All the constituent elements of the wireless charging system 10 illustrated in FIG. 5 are not required constituent elements, and the wireless charging system 10 may be implemented by more constituent elements than the constituent elements illustrated in FIG. 5 or less constituent elements therethan. Here, the wireless charging equipment 300, the first terminal 200, and the second terminal 400 charge a battery provided in the corresponding first terminal 200 or second terminal 200 based on a charging signal transmitted from the wireless charging equipment 300 through alliance for wireless power (A4WP) scheme (alternatively, a magnetic resonance scheme). Further, the corresponding wireless charging equipment 300, the first terminal 200, and the second terminal 400 use BLE for low power in Bluetooth.

[0179] While one or more contents to be shared by the first terminal 200 and sharing target information are being stored, when the first terminal 200 communicates with the wireless charging equipment 300, the first terminal 200 receives information on one or more (alternatively, a plurality of) terminals including the first terminal 200 which is charging through the corresponding wireless charging equipment 300 transmitted from the wireless charging equipment 300. Thereafter, when the received information on one or more terminals is included in the sharing target information, the first terminal 200 exchanges connection condition information with at least one terminal (for example, the second terminal 400) through the wireless charging equipment 300 coinciding with the sharing target information and the information on one or more terminals and finally determines a connection method between the first terminal 200 and at least one terminal. Thereafter, the first terminal 200 and at least one terminal directly communicate with each other through the same dedicated app pre-installed in each terminal based on the determined final connection condition information. Thereafter, the second terminal 400 receives one or more contents to be provided (alternatively, shared) from the first terminal 200 and stores or outputs one or more received contents.

[0180] The first control unit 220 selects one (alternatively, one or more/a plurality of) content(s) among the plurality of contents pre-stored (alternatively, registered) in a second storage unit (not illustrated). Here, the corresponding contents may be files (for example, including images, audios, videos, motion pictures, games, map information provided from a map providing program, documents, and the like) and also be a folder (alternatively, folder information) including one or more files.

[0181] Further, the first control unit 220 select sharing target information to share the selected one (alternatively, one or more/a plurality of) content(s). Here, the sharing target information includes information (for example, including identification information, a telephone number, an e-mail address, and the like) on one or more (alternatively, a plurality of) second terminals 400. That is, the first control unit 220 selects (alternatively, generates) sharing target information including one or more (alternatively, a plurality of) telephone numbers (alternatively, identification information corresponding to a corresponding telephone numbers) among the plurality telephone numbers pre-stored in the first storage unit (alternatively, according to user's selection/control of the first terminal).

[0182] Further, the first control unit 220 receives information (for example, including identification information, a telephone number, an e-mail address, messenger information, and the like) on one or more (alternatively, a plurality of) terminals which is currently charging through the corresponding wireless charging equipment 300 transmitted from the wireless charging equipment 300 through the first communication unit 210.

[0183] Further, the first control unit 220 generates a charging terminal information request signal for requesting the information on one or more (alternatively, a plurality of) terminals which is currently charging through the corresponding wireless charging equipment 300 in which the first terminal 200 is charging and transmits the generated charging terminal information request signal to the wireless charging equipment 300 through the first communication unit 210.

[0184] Further, the first control unit 220 may also receive the information on one or more (alternatively, a plurality of) terminals which is currently charging through the corresponding wireless charging equipment 300 which is transmitted from the wireless charging equipment 300 through the first communication unit 210 in response to the transmitted charging terminal information request signal.

[0185] Further, the first control unit 220 determines (alternatively, verifies) whether the received information on one or more (alternatively, a plurality of) terminals which is charging through the corresponding wireless charging equipment 300 is included in the sharing target information.

[0186] Further, as the determined result (alternatively, the verified result), when the received information on one or more (alternatively, a plurality of) terminals which is charging through the corresponding wireless charging equipment 300 is not included in the sharing target information, the first control unit 220 displays (alternatively, outputs) information representing that the terminal corresponding to the sharing target information is not included in the received information on one or more (alternatively, a plurality of) terminals which is charging through the corresponding wireless charging equipment 300 (alternatively, information representing that a sharing target terminal included in the sharing target information is not charging through the corresponding wireless charging equipment 300) on the second display unit (not illustrated) and deletes (alternatively, discards) information on one or more (alternatively, a plurality of) terminals or stores the information in the first storage unit. In this case, the wireless charging equipment 300 continuously performs the charging function with the first terminal 200.

[0187] Further, as the determined result, when the received information on one or more (alternatively, a plurality of) terminals which is charging through the corresponding wireless charging equipment 300 is included in the sharing target information, the first control unit 220 verifies a specific terminal (alternatively, at least one specific terminal) which is charging through the wireless charging equipment 300 in the sharing target information. In the embodiment of the present invention, the corresponding specific terminal is described as the second terminal 400, but is not limited thereto, and the corresponding specific terminal may be at least one (alternatively, a plurality of) terminal(s).

[0188] Further, the first control unit 220 generates connection condition information (alternatively, access condition information/communication mode information) in order to determine the connection condition with the second terminal 400 which is the verified specific terminal. Here, the connection condition information may include any one communication mode among wireless communication modes such as Bluetooth and a WiFi mode. In this case, only when the second terminal 400 pre-permits (alternatively, admits) the content reception, a process of exchanging the connection condition information between the first terminal 200 and the second terminal 400 may be performed.

[0189] Further, the first control unit 220 exchanges the connection condition information (alternatively, the access condition information/the communication mode information) with the verified second terminal 400 via the wireless charging equipment 300 (alternatively, through the wireless charging equipment 300).

[0190] As such, the first terminal 200 and the second terminal 400 exchange the connection condition information with each other through the wireless charging equipment 300. Further, the first control unit 220 determines (alternatively, sets) final connection condition information by exchanging the corresponding connection condition information with the second terminal 400.

[0191] Further, the first control unit 220 directly communicates with (alternatively, accesses/is connected with) the second terminal 400 based on the verified final connection condition information. In this case, the first terminal 200 and the second terminal 400 may directly communicate with each other through the dedicated app pre-installed in each terminal.

[0192] Further, the first control unit 220 receives the selected one (alternatively, one or more/a plurality of) contents to the second terminal 400 through the first communication unit 210. In this case, the first control unit 220 may also transmit corresponding one (alternatively, one or more/a plurality of) content(s) to the second terminal 400 through the first communication unit 210 only when the second terminal 400 permits the content reception.

[0193] Further, when one (alternatively, one or more/a plurality of) content(s) is shared between the first control unit 220 and the second terminal 400, one (alternatively, one or more/a plurality of) content(s) selected in the first terminal 200 may synchronizes (alternatively, be shared) with the second terminal 400 by a synchronization scheme (for example, including file synchronization, folder synchronization, and the like).

[0194] As illustrated in FIG. 6, the second terminal 400 is constituted by a third communication unit 410, a third control unit 420, and a third battery 430. All the constituent elements of the second terminal 400 illustrated in FIG. 6 are not essential constituent elements, and the second terminal 400 may be implemented by more constituent elements than the constituent elements illustrated in FIG. 6 or less constituent elements therethan. Here, the second terminal 400 includes a PRU (not illustrated).

[0195] The third communication unit 410 communicates with other terminals by a wired/wireless communication method. Further, the third communication unit 410 communicates with the wireless charging equipment 300 using a BLE scheme by using BLE.

[0196] Further, the third communication unit 410 receives a power beacon signal transmitted from the wireless charging equipment 300.

[0197] The third control unit 420 executes an overall control function of the second terminal 400.

[0198] Further, a charging function between the third control unit 420 and the wireless charging equipment 300 is the same as the charging function between the first control unit 220 and the wireless charging equipment 300 which are included in the first terminal 200 described above, and the description thereof will be omitted.

[0199] Further, the third control unit 420 transmits identification information of the second terminal 400 to the wireless charging equipment 300 which is charging through the third communication unit 410.

[0200] Further, when the corresponding second terminal 400 is included in the sharing target information to share the contents in the first terminal 200 among one or more (alternatively, a plurality of) terminals which is charging through the wireless charging equipment 300 including the second terminal 400, the third control unit 420 receives the connection condition information (alternatively, the access condition information/the communication mode information) transmitted from the first terminal 200 via the wireless charging equipment 300 through the third communication unit 410. Here, the connection condition information may include any one communication mode among wireless communication modes such as Bluetooth and a WiFi mode. In this case, only when the second terminal 400 pre-permits (alternatively, admits) the content reception, a process of exchanging the connection condition information between the first terminal 200 and the second terminal 400 may be performed.

[0201] Further, the third control unit 420 generates response information (for example, including acceptance of the connection condition, generation of another connection condition information, and the like) representing whether to accept the received connection condition information.

[0202] Further, the third control unit 420 transmits the generated response information to the first terminal 200 via the wireless charging equipment 300 in response to the received connection condition information.

[0203] As such, the first terminal 200 and the second terminal 400 exchange the connection condition information with each other via the wireless charging equipment 300 and determine the final connection condition information.

[0204] Further, the third control unit 420 directly communicates with (alternatively, accesses/is connected with) the first terminal 200 based on the determined final connection condition information. In this case, the first terminal 200 and the second terminal 400 may directly communicate with each other through the dedicated app pre-installed in each terminal.

[0205] Further, the third control unit 420 receives one (alternatively, one or more/a plurality of) sharing content(s) transmitted from the first terminal 200 through the third communication unit 410. In this case, the third control unit 420 may receive the corresponding one (alternatively, one or more/a plurality of) content(s) transmitted from the first terminal 200 only when the second terminal 400 pre-permits the content reception. Here, when the first terminal 200 and the second terminal 400 directly communicate with each other, the direct communication between the first terminal 200 and the second terminal 400 may be continuously performed regardless of a case where the first terminal 200 or the second terminal 400 is charging through the wireless charging equipment 300, the charging stops, or the charging is completed.

[0206] Further, when the second terminal 400 does not pre-permit the content reception, the third control unit 420 immediately discards (alternatively, deletes) or does not store the corresponding one (alternatively, one or more/a plurality of) content(s) transmitted from the first terminal 200.

[0207] Further, the third control unit 420 stores the received one (alternatively, one or more/a plurality of) content(s) in a third storage unit (not illustrated). Further, the third control unit 420 displays the received one (alternatively, one or more/a plurality of) content(s) on a third display unit (not illustrated) through a dedicated app.

[0208] Further, the third control unit 420 generates sharing state information. Here, the sharing state information includes information on the contents shared between terminals, identification information of the first terminal 200 and the second terminal 400 sharing the contents with each other, identification information of the wireless charging equipment 300, a sharing time, and the like. Further, the third control unit 420 transmits the generated sharing state information to the wireless charging equipment 300 or the service providing device (not illustrated) through the third communication unit 410.

[0209] In this case, the corresponding service providing device stores the sharing state information as big data for providing an additional service. Further, when the first terminal 200 or the second terminal 400 visits a predetermined store (alternatively, visits the store where the corresponding wireless charging equipment 300 is installed), the sharing state information stored in the service providing device may be used as big data for providing the additional service from the service providing device.

[0210] Further, the service providing device generates additional service information for each terminal based on the sharing state information.

[0211] Further, the service providing device transmits the generated additional service information to the corresponding first terminal 200 or second terminal 400 through the wireless charging equipment 300. Here, the additional service information includes various contents curation such as promotion information for each store provided with the wireless charging equipment 300, coupon information, marketing information, review information for each product, news information, and music information.

[0212] Further, when a purchase function (alternatively, a payment function) for a specific product included in the additional service information transmitted to the first terminal 200 or the second terminal 400 is requested, the service providing device may also perform the purchase function for the corresponding product by interlocking among the wireless charging equipment 300, the first terminal 200 (alternatively, the second terminal 400), and the POS terminal (not illustrated).

[0213] The third battery 430 supplies the power to the corresponding second terminal 400.

[0214] Further, the third battery 430 performs a charging function based on the charging signal transmitted from the wireless charging equipment 300 by a control of the third control unit 420.

[0215] The second control unit 320 verifies one or more (alternatively, a plurality of) terminals which is charging through the wireless charging equipment 300 in real time.

[0216] Further, the second control unit 320 verifies information (for example, including identification information, a telephone number, an e-mail address, and the like) on one or more (alternatively, a plurality of) terminals which is charging through the wireless charging equipment 300, which are verified in real time.

[0217] Further, the second control unit 320 transmits the verified information on one or more (alternatively, a plurality of) terminals to one or more (alternatively, a plurality of) terminals which is charging through the second communication unit 310, respectively. In this case, the second control unit 320 may transmit the corresponding information on one or more (alternatively, a plurality of) terminals to one or more (alternatively, a plurality of) terminals which is charging through the second communication unit 310 in an empty time period (alternatively, a standby time period) in which the charging signal is not transmitted to one or more (alternatively, a plurality of) terminals, respectively.

[0218] Further, the second control unit 320 may also transmit the corresponding information to only the specific terminal requesting the information on one or more (alternatively, a plurality of) terminals which is currently charging.

[0219] That is, the second control unit 320 receives the charging terminal information request signal for requesting the information on one or more (alternatively, a plurality of) terminals which is currently charging which is transmitted from the first terminal 200, through the second communication unit 310.

[0220] Further, the second control unit 320 transmits the information on one or more (alternatively, a plurality of) terminals which is currently charging through the wireless charging equipment 300 to the first terminal 200 through the second communication unit 310 in response to the received charging terminal information request signal.

[0221] Further, when the second terminal 400 as the target terminal to share the contents to be shared in the first terminal 200 is currently charging through the wireless charging equipment 300, the second control unit 320 receives the connection condition information (alternatively, the access condition information/the communication mode information) transmitted from the first terminal 200 through the second communication unit 310. Here, the connection condition information may include any one communication mode among wireless communication modes such as Bluetooth and a WiFi mode.

[0222] Further, the second control unit 320 transmits the received connection condition information (alternatively, the access condition information/the communication mode information) to the corresponding second terminal 400 through the second communication unit 310.

[0223] As such, the first terminal 200 and the second terminal 400 exchange the connection condition information with each other via the wireless charging equipment 300.

[0224] Further, in the embodiment of the present invention, verifying the specific terminal (for example, including the second terminal 400 and the like) which coincides with the sharing target information and the information on the terminal which is charging through the wireless charging equipment 300 and performing the direct communication function with the verified specific terminal in the first terminal 200 are described, but are not limited thereto. The wireless charging equipment 300 may be configured to receive (alternatively, acquire) the sharing target information from the first terminal 200 and verify the specific terminal which coincides with the received sharing target information and the information on the terminal which is charging through the wireless charging equipment 300. Further, the wireless charging equipment 300 transmits the verified information on the specific terminal to the first terminal 200. Thereafter, the first terminal 200 may also perform a direct communication function with the corresponding specific terminal based on the information on the specific terminal provided from the wireless charging equipment 300.

[0226] Further, as such, a method of directly exchanging mass data among the plurality of terminals which is charging through the wireless charging equipment may be provided.

[0227] Hereinafter, a control method of a wireless charging system according to the present invention will be described in detail with reference to FIGS. 1 to 9.

[0228] FIG. 7 is a flowchart illustrating a control method of a wireless charging system according to a first embodiment of the present invention.

[0229] First, the first terminal 200 selects one (alternatively, one or more/a plurality of) content(s) among the plurality of contents pre-stored in the service providing device 100 while communicating. Here, the corresponding contents may be files (for example, including images, audios, videos, motion pictures, games, map information provided from a map providing program, documents, and the like) and also be a folder (alternatively, folder information) including one or more files.

[0230] Further, the first terminal 200 receives sharing link information on the corresponding selected contents provided (alternatively, transmitted) from the service providing device 100 and stores the received sharing link information. Here, the sharing link information includes address information in which the corresponding contents are stored in the corresponding service providing device 100, and the like.

[0231] As an example, the first terminal 200 selects an ∘∘ image among the plurality of contents pre-stored in the service providing device 100 while communicating and receives the sharing link information corresponding to the address information in which the ∘∘ image selected from the corresponding service providing device 100 provided from the service providing device 100 is stored (S710).

[0232] Thereafter, the first terminal 200 selects sharing target information to share the corresponding sharing link information. Here, the sharing target information includes information (for example, including identification information, a telephone number, an e-mail address, and the like) on one or more (alternatively, a plurality of) second terminals 400.

[0233] That is, the first terminal 200 selects sharing target information to share the corresponding sharing link information in information (for example, including identification information, a telephone number, an e-mail address, and the like) on the plurality of second terminals 400 prestored in the first terminal 200.

[0234] As an example, the first terminal 200 selects the sharing target information including telephone numbers of the first terminal, the second terminal, and the third terminal from the information on the plurality of pre-stored second terminals 400 (S720).

[0235] Thereafter, when the first terminal 200 exists in a BLE range of the wireless charging equipment 300, the first terminal 200 communicates with the wireless charging equipment 300. Further, the first terminal 220 charges the first battery 230 included in the first terminal 200 based on the charging signal transmitted from the wireless charging equipment 300.

[0236] Further, the first terminal 200 transmits the sharing link information, the sharing target information, the identification information of the first terminal 200, and the like to the wireless charging equipment 300 while communicating. In this case, the first terminal 200 may transmit the corresponding sharing link information, the sharing target information, the identification information of the first terminal 200, and the like to the wireless charging equipment 300 in an empty time period (alternatively, a standby time period) in which the charging signal is not transmitted to and received from the wireless charging equipment 300. Here, the identification information of the first terminal 200 includes an MDN, a mobile IP, a mobile MAC, Sim card unique information, a serial number, and the like.

[0237] As an example, when the first terminal 200 exists in a BLE range of the wireless charging equipment 300, the communication function between the first terminal 200 and the wireless charging equipment 300 is performed. Thereafter, the first terminal 200 transmits the sharing link information (for example, the sharing link information corresponding to the address information in which the ∘∘ image is stored), the sharing target information (for example, the sharing target information including the telephone numbers of the first terminal, the second terminal, and the third terminal), the identification information of the first terminal 200, and the like to the wireless charging equipment 300 (S730).

[0238] Thereafter, the wireless charging equipment 300 receives the sharing link information, the sharing target information, the identification information of the first terminal 200, and the like, which are transmitted from the first terminal 200.

[0239] Further, the wireless charging equipment 300 stores the received sharing link information, sharing target information, identification information of the first terminal 200, and the like.

[0240] As an example, the wireless charging equipment 300 stores the sharing link information (for example, the sharing link information corresponding to the address information in which the ∘∘ image is stored), the sharing target information (for example, the sharing target information including the telephone numbers of the first terminal, the second terminal, and the third terminal), the identification information of the first terminal 200, and the like, which are transmitted from the first terminal 200 (S740).

[0241] Thereafter, while the corresponding first terminal 200 is charging by interlocking between the first terminal 200 and the wireless charging equipment 300, the wireless charging equipment 300 receives the identification information of the second terminal 400 (alternatively, the information on the second terminal 400) transmitted from the second terminal 400. Here, the communication method between wireless charging equipment 300 and the second terminal 400 may be any one of wired/wireless communication methods. In this case, the second terminal 400 communicates with (alternatively, accesses) the wireless charging equipment 300 through the dedicated app pre-installed in the corresponding second terminal 400 and may transmit the identification information of the corresponding second terminal 400 to the wireless charging equipment 300.

[0242] As an example, while transmitting the charging signal to the first terminal 200 connected to the corresponding wireless charging equipment 300 (alternatively, positioned in the BLE radius of the corresponding wireless charging equipment 300) at a predetermined time interval (for example, 250 ms) in the wireless charging equipment 300, the wireless charging equipment 300 communicates with the second terminal 400 through a specific app pre-installed (alternatively, set) in the second terminal 400 and receives the identification information of the second terminal 400 (alternatively, a telephone number of the second terminal 400) transmitted from the corresponding second terminal 400 (S750).

[0243] Thereafter, the wireless charging equipment 300 determines (alternatively, verifies) whether the identification information of the second terminal 400 is included in the pre-stored sharing target information.

[0244] As an example, the wireless charging equipment 300 determines whether the received identification information of the second terminal 400 (alternatively, the telephone number of the second terminal 400) is included in the stored sharing target information (for example, the sharing target information including the telephone numbers of the first terminal, the second terminal, and the third terminal) (S760).

[0245] As the determined result, when the identification information of the second terminal 400 is not included in the pre-stored sharing target information, the wireless charging equipment 300 deletes (alternatively, discards) or stores the identification information of the corresponding second terminal 400. In this case, the wireless charging equipment 300 continuously performs the charging function with the first terminal 200.

[0246] As an example, when the received identification information of the second terminal 400 (alternatively, the telephone number of the second terminal 400) is not included in the stored sharing target information (for example, the sharing target information including the telephone numbers of the first terminal, the second terminal, and the third terminal), the wireless charging equipment 300 continuously performs the charging function with the first terminal 200 and deletes the identification information of the corresponding second terminal 400 (S770).

[0247] Further, as the determined result, when the identification information of the second terminal 400 is included in the pre-stored sharing target information, the wireless charging equipment 300 transmits the stored sharing link information to the second terminal 400. In this case, the wireless charging equipment 300 continuously performs the charging function with the first terminal 200.

[0248] As an example, when the received identification information of the second terminal 400 (alternatively, the telephone number of the second terminal 400) is included in the stored sharing target information (for example, the sharing target information including the telephone numbers of the first terminal, the second terminal, and the third terminal), the wireless charging equipment 300 continuously performs the charging function with the first terminal 200 and transmits the stored sharing link information (for example, the sharing link information corresponding to the address information in which the ∘∘ image is stored) to the second terminal 400 (S780).

[0249] Thereafter, the second terminal 400 receives the sharing link information transmitted from the wireless charging equipment 300 in response to the received identification information of the second terminal 400 (alternatively, the information on the second terminal 400). Further, the second terminal 400 stores the received sharing link information.

[0250] Further, the second terminal 400 communicates with the service providing device 100 related with the corresponding sharing link information based on the received sharing link information.

[0251] Further, the second terminal 400 requests the transmission of the contents corresponding to the corresponding sharing link information to the service providing device 100 based on the corresponding sharing link information.

[0252] Further, the second terminal 400 receives the contents corresponding to the corresponding sharing link information transmitted from the service providing device 100 in response to the request and outputs or stores the received contents.

[0253] In this case, the corresponding service providing device 100 stores sharing state information as big data for providing an additional service. Here, the corresponding sharing state information includes identification information of the first terminal 200 related with the sharing state information, identification information of the second terminal 400, sharing link information (alternatively, sharing target), a sharing time, and the like. Further, when the first terminal 200 or the second terminal 400 visits a predetermined store, the sharing state information stored in the service providing device 100 may be used as big data for providing the additional service from the service providing device 100.

[0254] As an example, the second terminal 400 receives the sharing link information (for example, the sharing link information corresponding to the address information in which the ∘∘ image is stored) transmitted from the wireless charging equipment 300 accessed through the pre-installed (alternatively, set) specific app. Further, the second terminal 400 accesses the service providing device 100 corresponding to the received sharing link information (for example, the sharing link information corresponding to the address information in which the ∘∘ image is stored).

[0255] Further, the second terminal 400 requests the transmission of the ∘∘ image corresponding to the corresponding sharing link information based on the sharing link information. Further, the second terminal 400 receives the ∘∘ image corresponding to the corresponding sharing link information transmitted (alternatively, provided) from the service providing device 100 in response to the corresponding request and stores or displays the received ∘∘ image (S790).

[0256] FIG. 8 is a flowchart illustrating a control method of a wireless charging system according to a second embodiment of the present invention.

[0257] First, the first terminal 200 registers (alternatively, stores) a coupon issued from the service providing device 100 or a coupon server (not illustrated). In this case, the first terminal 200 may register (alternatively, store/interlock) the corresponding coupon in a dedicated app preinstalled in the first terminal 200. Here, the corresponding coupon may be generated based on coupon information including an affiliated company title (alternatively, a brand/affiliated company name) issuing a coupon, a coupon name, a unique code (alternatively, a coupon number), a title, a benefit, a usage place, a usage period (alternatively, an expiration date), a usage method, a coupon type (for example, a free coupon or a paid coupon), a store title (alternatively, identification information of one or more (alternatively, a plurality of) wireless charging equipment capable of using the coupling) capable of using the corresponding coupon, and the like.

[0258] Further, the first terminal 200 may register the coupon issued from the service providing device 100 or the coupon server (not illustrated) through an SMS format, a push message format, an e-mail format, QR code recognition, and the like.

[0259] As an example, the first terminal 200 registers a free coupon for a cup of Americano of a ∘∘ brand, which is issued from the service providing device 100 in a ΔΔ app installed in the first terminal 200. Here, the corresponding free coupon may include identification information of first to 100-th wireless charging equipment (S810).

[0260] Thereafter, when the first terminal 200 exists in a BLE range of the wireless charging equipment 300, the first terminal 200 communicates with the wireless charging equipment 300. Further, the first terminal 200 charges the battery 230 included in the first terminal 200 based on the charging signal transmitted from the wireless charging equipment 300. In this case, the first terminal may verify the identification information (alternatively, unique information of the wireless charging equipment 300) of the wireless charging equipment 300.

[0261] As an example, when the first terminal 200 exists in the BLE range of first wireless charging equipment, the first terminal 200 communicates with the first wireless charging equipment. Further, the first terminal 200 receives identification information of the first wireless charging equipment transmitted from the first wireless charging equipment (S820).

[0262] Thereafter, while the first terminal 200 is wirelessly charged through the wireless charging equipment 300, the first terminal 200 executes a specific app preinstalled in the first terminal 200 and selects one (alternatively, one or more/a plurality of) coupon(s) among a plurality of coupons registered (alternatively, stored) the specific executed app.

[0263] As an example, while the first terminal 200 is wirelessly charged by interlocking with the wireless charging equipment 300, the first terminal 200 executes the specific app and selects the free coupon for a cup of Americano of the ∘∘ brand among the plurality of coupons registered in the specific executed app (S830).

[0264] Thereafter, when a predetermined button is selected (alternatively, when the corresponding button is selected/clicked while the coupon is selected), the first terminal 200 verifies (alternatively, determines) whether the selected coupon is a coupon usable in a store with the wireless charging equipment 300.

[0265] That is, when the predetermined button is selected, the first terminal 200 verifies whether the received identification information of the wireless charging equipment 300 is included in the identification information of one or more (alternatively, the plurality of) wireless charging equipment capable of using the corresponding coupon, which is included in coupon information on the selected coupon.

[0266] As an example, when a predetermined use button is selected, the first terminal 200 verifies whether the received identification information of the first wireless charging equipment is included in the identification information of the plurality of wireless charging equipment capable of using the corresponding free coupon for a cup of Americano, which is included in the coupon information on the free coupon for a cup of Americano of the ∘∘ brand (S840).

[0267] According to a result of the verification (alternatively, a result of the determination), when the selected coupon is not the coupon usable in the store with the wireless charging equipment 300 (alternatively, when the received identification information of the wireless charging equipment 300 is not included in the identification information of one or more (alternatively, the plurality of) wireless charging equipment capable of using the corresponding coupon included in the coupon information on the selected coupon), the first terminal 200 outputs information indicating whether the corresponding coupon may not be shared. In this case, the first terminal 200 continuously performs a charging function with the wireless charging equipment 300.

[0268] As an example, when the identification information of the first wireless charging equipment is not included in the identification information of the plurality of wireless charging equipment capable of using the free coupon for a cup of Americano, which is included in the coupon information on the free coupon for a cup of Americano of the ∘∘ brand, the first terminal 200 outputs the information indicating that the free coupon for a cup of Americano of the ∘∘ brand may not be shared (S850).

[0269] Further, according to a result of the verification, when the selected coupon is the coupon usable in the store with the corresponding wireless charging equipment 300 (alternatively, the received identification information of the wireless charging equipment 300 is included in the identification information of one or more (alternatively, the plurality of) wireless charging equipment capable of using the corresponding coupon included in the coupon information on the selected coupon), the first terminal 200 transmits the coupon information on the coupon, the identification information of the wireless charging equipment 300, the identification information of the first terminal 200, and the like to one or more second terminals 400 which are charging through the wireless charging equipment 300. In this case, the first terminal 200 continuously performs the charging function with the wireless charging equipment 300.

[0270] Here, the first terminal 200 may transmit the coupon information on the corresponding coupon, the identification information of the wireless charging equipment 300, the identification information of the first terminal 200, and the like to one or more second terminals 400 via the wireless charging equipment 300.

[0271] Further, the first terminal 200 receives information (for example, identification information, a phone number, an e-mail address, messenger information, and the like) on one or more second terminal 400 which is charged through the corresponding wireless charging equipment 300, which is transmitted from the wireless charging equipment 300. Thereafter, the first terminal 200 may transmit the coupon information on the coupon, the identification information of the wireless charging equipment 300, the identification information of the first terminal 200, and the like to one or more second terminals 400 through a dedicated app based on the received information on one or more second terminals 400.

[0272] As an example, when the identification information of the first wireless charging equipment is included in the identification information of the plurality of wireless charging equipment capable of using the free coupon for a cup of Americano, which is included in the coupon information on the free coupon for a cup of Americano of the ∘∘ brand, the first terminal 200 transmits the coupon information on the free coupon for a cup of Americano, the identification information of the first wireless charging equipment, the identification information of the first terminal 200, and the like to the first wireless charging equipment. Thereafter, the first wireless charging equipment receives the coupon information on the free coupon for a cup of Americano, the identification information of the first wireless charging equipment, the identification information of the first terminal 200, and the like, which are transmitted from the first terminal 200. Further, the first wireless charging equipment verifies one or more second terminals 400 which are currently charged through the corresponding first wireless charging equipment. Thereafter, the wireless charging equipment 300 transmits the coupon information on the free coupon for a cup of Americano, the identification information of the first wireless charging equipment, the identification information of the first terminal 200, and the like, to one or more second terminals 200 which are verified.

[0273] As another example, when the identification information of the first wireless charging equipment is included in the identification information of the plurality of wireless charging equipment capable of using the free coupon for a cup of Americano, which is included in the coupon information on the free coupon for a cup of Americano of the ∘∘ brand, the first terminal 200 receives the information (for example, the identification information, the phone number, the e-mail address, the messenger information, and the like) on one or more second terminals 400 which are charged through the first charging equipment, which is transmitted from the first wireless charging equipment. Thereafter, the first terminal 200 transmits the coupon information on the free coupon for a cup of Americano, the identification information of the first wireless charging equipment, the identification information of the first terminal 200, and the like to one or more second terminals in a text message format based on the received information on one or more second terminals 400 (S860).

[0274] Thereafter, each of one or more second terminals 200 receives the coupon information on the coupon, which is transmitted from the first terminal 200 or the wireless charging equipment 300, the identification information of the wireless charging equipment 300, the identification information of the first terminal 200, and the like. Further, the second terminal 400 determines (alternatively, verifies) whether the second terminal 400 is charged through the wireless charging equipment 300 or the identification information of the wireless charging equipment 300 in which the second terminal 400 matches the received identification information of the wireless charging equipment 300.

[0275] That is, in order to verify whether the second terminal 400 is positioned at the store capable of using the received coupon information (alternatively, the coupon corresponding to the corresponding coupon information), the second terminal 400 determines whether the second terminal 400 is charged through the wireless charging equipment 300 installed at the store or the identification information of the wireless charging equipment 300 that performing charging matches the identification information of the wireless charging equipment, which is transmitted from the first terminal 200 (alternatively, the wireless charging equipment 300).

[0276] As an example, the second terminal 400 receives the coupon information on the free coupon for a cup of Americano, the identification information of the first wireless charging equipment, the identification information of the first terminal 200, and the like, which are transmitted from the first terminal 200. Further, the second terminal 400 verifies identification information of second wireless charging equipment which currently performs charging. Thereafter, the second terminal 400 determines whether the identification information of the second wireless charging equipment which performs charging matches (is the same as) the identification information of the first wireless charging equipment, which is transmitted from the first terminal 200 (S870).

[0277] According to a result of the determination (alternatively, according to a result of the verification), when the second terminal 400 is not charged through the wireless charging equipment 300 or when the identification information of the wireless charging equipment 300 in which the second terminal 400 is charged does not match the received identification information of the wireless charging equipment 300, the second terminal 400 deletes (alternatively, discards) or does not store the received coupon information.

[0278] As an example, when the identification information of the second wireless charging equipment that performs charging is not the same as the identification information of the first wireless charging equipment transmitted from the first terminal 200, the second terminal 400 deletes the coupon information on the free coupon for a cup of Americano, which is transmitted from the first terminal 200 (S880).

[0279] Further, according to the result of the determination, when the second terminal 400 is charged through the wireless charging equipment 300 or when the identification information of the wireless charging equipment 300 in which the second terminal 400 is charged matches the received identification information of the wireless charging equipment 300, the second terminal 400 registers (alternatively, stores) the coupon corresponding to the received coupon information in a specific app (for example, the same as the specific app installed in the first terminal 200) preinstalled in the corresponding second terminal 400. In this case, the second terminal 400 continuously performs the charging function with the wireless charging equipment 300.

[0280] Further, the second terminal 400 generates coupon transfer completion information (alternatively, coupon registration completion information) and transmits the generated coupon transfer completion information to the service providing device 100, the first terminal 200, the wireless charging equipment 300, and the like. Here, the coupon transfer completion information includes information indicating that issuing the coupon is completed, the identification information of the second terminal 400, the identification information of the first terminal 200, the identification information of the wireless charging equipment 300, the coupon information, and the like.

[0281] As an example, when the identification information of the second wireless charging equipment that performs charging is the same as the identification information of the first wireless charging equipment transmitted from the first terminal 200, the second terminal 400 registers the free coupon for a cup of Americano, which corresponds to the coupon information for the free coupon of a cup of Americano, which is transmitted from the dedicated app, in a ΔΔ app installed in the corresponding second terminal. Further, the second terminal 400 generates coupon transfer completion information including information indicating that issuing the free coupon for a cup of Americano, the identification information of the second terminal 400, the identification information of the first terminal 200, the identification information of the first wireless charging equipment, the coupon information, and the like and transmits the generated coupon transfer completion information to the service providing device 100, the first terminal 200, the first wireless charging equipment, and the like.

[0282] As another example, when the identification information of the second wireless charging equipment that performs charging is the same as the identification information of the first wireless charging equipment transmitted from the first terminal 200, the second terminal 400 registers the free coupon for a cup of Americano, which corresponds to the coupon information for the free coupon of a cup of Americano, which is received in the text message format, in a ΔΔ app installed in the second terminal. Further, the second terminal 400 generates coupon transfer completion information including information indicating that issuing the free coupon for a cup of Americano, the identification information of the second terminal 400, the identification information of the first terminal 200, the identification information of the first wireless charging equipment, the coupon information, and the like and transmits the generated coupon transfer completion information to the service providing device 100, the first terminal 200, the first wireless charging equipment, and the like (S890).

[0283] FIG. 9 is a flowchart illustrating a control method of a wireless charging system according to a third embodiment of the present invention.

[0284] First, the first terminal 200 selects one (alternatively, one or more/a plurality of) content(s) among the plurality of contents pre-stored (alternatively, registered) in the first terminal 200. Here, the corresponding contents may be files (for example, including images, audios, videos, motion pictures, games, map information provided from a map providing program, documents, and the like) and also be a folder (alternatively, folder information) including one or more files.

[0285] Further, the first terminal 200 selects sharing target information to share the selected content. Here, the sharing target information includes information (for example, including identification information, a telephone number, an e-mail address, and the like) on one or more (alternatively, a plurality of) other terminals 400.

[0286] That is, the first terminal 200 selects sharing target information including one or more (alternatively, a plurality of) telephone numbers (alternatively, identification information corresponding to a corresponding telephone numbers) among the plurality telephone numbers pre-stored (alternatively, registered) in the first terminal 200.

[0287] As an example, the first terminal 200 selects a ∘∘ image among the plurality of contents prestored in the first terminal 200.

[0288] Further, the first terminal 200 selects sharing target information including telephone numbers of a second terminal, a third terminal, and a fourth terminal among telephone numbers for the plurality of pre-stored other terminals 400 (S910).

[0289] Thereafter, when the first terminal 200 exists in a BLE range of the wireless charging equipment 300, the first terminal 200 communicates with the wireless charging equipment 300. Further, the first terminal 200 charges the first battery 230 included in the first terminal 200 based on the charging signal transmitted from the wireless charging equipment 300. In this case, the first terminal 200 transmits the identification information of the corresponding first terminal 200 to the wireless charging equipment 300. Here, the identification information of the first terminal 200 includes an MDN, a mobile IP, a mobile MAC, Sim card unique information, a serial number, and the like.

[0290] As an example, when the first terminal 200 exists in a BLE range of the wireless charging equipment 300, the communication function between the first terminal 200 and the wireless charging equipment 300 is performed. Further, the first terminal 200 transmits the identification information of the corresponding first terminal 200 to the wireless charging equipment 300 (S920).

[0291] Thereafter, the wireless charging equipment 300 verifies one or more (alternatively, a plurality of) terminals including the first terminal 200 which is currently charging through the corresponding wireless charging equipment 300 and verifies information (for example, including identification information, a telephone number, an e-mail address, and the like) on the verified one or more (alternatively, a plurality of) terminals.

[0292] Further, the wireless charging equipment 300 transmits the verified information on one or more (alternatively, a plurality of) terminals to one or more (alternatively, a plurality of) terminals which is charging, respectively. In this case, the wireless charging equipment 300 may transmit the corresponding information on one or more (alternatively, a plurality of) terminals to one or more (alternatively, a plurality of) terminals which is charging in an empty time period (alternatively, a standby time period) in which the charging signal is not transmitted to one or more (alternatively, a plurality of) terminals, respectively.

[0293] As an example, while the charging signals are transmitted to the plurality of terminals including the first terminal 200 connected to the corresponding wireless charging equipment 300 (alternatively, positioned in the BLE radius of the corresponding wireless charging equipment 300) at a predetermined time interval (for example, 250 ms) in the wireless charging equipment 300, respectively, the wireless charging equipment 300 verifies the plurality of terminals including the first terminal 200 which is currently charging and verifies the verified telephone numbers of the plurality of terminals (alternatively, identification information corresponding to the corresponding telephone numbers), respectively. Thereafter, the wireless charging equipment 300 transmits the verified telephone numbers of the plurality of terminals to the corresponding plurality of terminals, respectively.

[0294] Further, in the embodiment of the present invention, transmitting the information on one or more (alternatively, a plurality of) terminals which is charging in the empty time period in the wireless charging equipment 300 to each terminals is described, but is not limited thereto. The wireless charging equipment 300 may transmit the information on one or more (alternatively, a plurality of) terminals which is charging only in a specific terminal (for example, the first terminal 200) requesting the information on the terminals which is currently charging through the corresponding wireless charging equipment 300.

[0295] Thereafter, the first terminal 200 which is charging through the wireless charging equipment 300 receives the information on one or more (alternatively, a plurality of) terminals which is charging through the wireless charging equipment 300 transmitted from the wireless charging equipment 300.

[0296] Further, the first terminal 200 determines (alternatively, verifies) whether the received information on one or more (alternatively, a plurality of) terminals which is charging through the wireless charging equipment 300 is included in the sharing target information.

[0297] As an example, the first terminal 200 determines whether the received telephone numbers of the plurality of terminals (alternatively, the identification information of the plurality of terminals) is included in pre-selected sharing target information (for example, sharing target information including telephone numbers of the second terminal, the third terminal, and the fourth terminal) (S940).

[0298] As the determined result (alternatively, the verified result), when the received information on one or more (alternatively, a plurality of) terminals which is charging through the wireless charging equipment 300 is not included in the sharing target information, the first terminal 200 outputs information representing that the terminal corresponding to the sharing target information is not included in the received information on one or more (alternatively, a plurality of) terminals which is charging through the corresponding wireless charging equipment 300 (alternatively, information representing that a sharing target terminal included in the sharing target information is not charging through the corresponding wireless charging equipment 300) and deletes (alternatively, discards) or stores the corresponding information on one or more (alternatively, the plurality of) terminals. In this case, the wireless charging equipment 300 continuously performs the charging function with the first terminal 200.

[0299] As an example, when the received telephone numbers of the plurality of terminals (for example, including telephone numbers of a fifth terminal and a sixth terminal) are not included in the pre-selected sharing target information (for example, the sharing target information including the telephone numbers of the second terminal, the third terminal, and the fourth terminal), the first terminal 200 continuously performs the charging function with the wireless charging equipment 300 and outputs information representing that the sharing target terminal included in the sharing target information is not charging through the corresponding wireless charging equipment 300 (S950).

[0300] Further, as the determined result, when the received information on one or more (alternatively, the plurality of) terminals which is charging through the corresponding wireless charging equipment 300 is included in the sharing target information, the first terminal 200 verifies the second terminal 400 as a specific terminal which is charging through the wireless charging equipment 300 in the sharing target information. Here, the specific terminal may be one or more (alternatively, a plurality of) terminals.

[0301] Further, the first terminal 200 exchanges connection condition information (alternatively, access condition information/communication mode information) with the verified second terminal 400 via the wireless charging equipment 300 (alternatively, through the wireless charging equipment 300). Here, the connection condition information may include any one communication mode among wireless communication modes such as Bluetooth and a WiFi mode. In this case, only when the second terminal 400 pre-permits (alternatively, admits) the content reception, a process of exchanging the connection condition information between the first terminal 200 and the second terminal 400 may be performed.

[0302] As such, the first terminal 200 and the second terminal 400 exchange the connection condition information with each other through the wireless charging equipment 300. Further, the first terminal 200 and the second terminal 400 determine (alternatively, sets) final connection condition information by exchanging the corresponding connection condition information with each other.

[0303] As an example, when the received telephone numbers of the plurality of terminals (for example, including telephone numbers of the second terminal and the fifth terminal) are included in the pre-selected sharing target information (for example, the sharing target information including the telephone numbers of the second terminal, the third terminal, and the fourth terminal), the first terminal 200 continuously performs the charging function with the wireless charging equipment 300 and transmits connection condition information of a WiFi scheme to the second terminal 400 via the wireless charging equipment 300. Thereafter, the second terminal 400 transmits response information (for example, acceptance/permission of the connection condition information of the WiFi scheme) representing whether to accept the received connection condition information of the WiFi scheme to the first terminal 200 via the wireless charging equipment 300. Thereafter, the first terminal 200 determines the final connection condition information (for example, the connection condition information of the WiFi scheme) based on the response information transmitted from the second terminal 400 (S960).

[0304] Thereafter, the first terminal 200 directly communicates with (alternatively, accesses/is connected with) the second terminal 400 based on the verified final connection condition information. In this case, the first terminal 200 and the second terminal 400 may directly communicate with each other through the dedicated app pre-installed in each terminal.

[0305] As an example, the first terminal 200 directly communicates with the second terminal 400 by the WiFi scheme through the preinstalled dedicated app.

[0306] Further, the first terminal 200 transmits one (alternatively, one or more/a plurality of) sharing content(s) selected above to the second terminal 400.

[0307] Further, the second terminal 400 receives one (alternatively, one or more/a plurality of) content(s) from the first terminal 200 and stores one (alternatively, one or more/a plurality of) received content(s). In this case, only when the second terminal 400 pre-permits (alternatively, admits) the content reception, the second terminal 400 may receive one (alternatively, one or more/a plurality of) content(s) transmitted from the first terminal 200. In addition, while the corresponding second terminal 400 does not pre-permit the content reception, a direct connection process with the first terminal 200 is not performed or one (alternatively, one or more/a plurality of) content(s) transmitted from the first terminal 200 is immediately discarded (alternatively, deleted) or not stored.

[0308] As an example, the first terminal 200 transmits the selected ∘∘ image to be shared to the second terminal 400 through the dedicated app. Thereafter, the second terminal 400 receives the ∘∘ image transmitted from the first terminal 200 through the dedicated app, stores the received ∘∘ image, and display the ∘∘ image through the dedicated app (S970).

[0309] FIG. 10 is a schematic configuration diagram for describing a content sharing system (alternatively, a wireless charging system) according to an embodiment of the present invention.

[0310] Referring to FIG. 10, the content sharing system 1000 (alternatively, the wireless charging system) according to the embodiment of the present invention means a system that supports content sharing between multiple terminals 1100 and 1200. The content sharing system according to the embodiment of the present invention may be configured to include a first terminal 1100 that intends to share contents and a second terminal 1200 that may share the contents. Further, the content sharing may be performed between the terminals 1100 and 1200 which are wirelessly charged.

[0311] The first terminal 1100 may sense one or more second terminals 1200 positioned within a predetermined radius and support a connection process with the second terminal 1200. In particular, the second terminal 1200 according to the embodiment of the present invention may exist in plural. When a plurality of connectable second terminals 1200 are detected, the first terminal 1100 may select an optimal second terminal 1200 among the plurality of second terminals 1200 and transmit and share the contents after establishing connection with the selected second terminal 1200.

[0312] For example, when the plurality of second terminals, that is, second terminal a 1210, second terminal b 1220, and second terminal c 1230 are detected, the first terminal 1100 may select the optimal second terminal, for example, the second terminal c 1230 by considering content related information including a content reproduction condition, for example, the kind, the type, reproduction information, and the like of the contents, time information, and the like, and may transmit and share the content after establishing the connection with the selected second terminal c 1230.

[0313] A content sharing method between the first terminal 1100 and the second terminal 1200 will be described below in more detail and the first terminal 1100 and the second terminal 1200 according to the embodiment of the present invention may be implemented in various forms. For example, the first terminal 1100 and the second terminal 1200 may adopt fixed terminals such as a smart TV, a desktop computer, and the like as well as mobile terminals such as a smart phone, a tablet PC, a personal digital assistants (PDA), a portable multimedia player (PMP), an MP3 player, a navigation, and the like.

[0314] Further, the first terminal 1100 and the second terminal 1200 may be implemented in a homogeneous form, but implemented in a heterogeneous form. For example, the first terminal 1100 may be the smart phone and the second terminal 1200 may be the smart TV. In the case of the first terminal 1100 and the second terminal 1200 of the present invention, modification of a portable apparatus is very diversified with the tendency of convergence of a digital apparatus and all portable apparatuses may not be enumerated, but units at levels equivalent to the levels the mentioned units may adopt the first terminal 1100 and the second terminal 1200 according to the present invention.

[0315] Moreover, the first terminal 1100 and the second terminal 1200 according to the embodiment of the present invention may transmit and receive various data via a communication network according to an operation of a user. Further, the first terminal 1100 and the second terminal 1200 may perform voice or data communication according to an implementation scheme thereof and transmit and receive various pieces of information with a separate web server.

[0316] Further, in order to support the process, the first terminal 1100 and the second terminal 1200 may include a memory storing a browser, a program, and a protocol for transmitting and receiving information, a microprocessor for calculating and controlling various programs by executing various programs, and the like. In this case, the microprocessors installed in the first terminal 1100 and the second terminal 1200 may process a program command for executing the method according to the embodiment of the present invention. In one implementation example, the processor may be a single-threaded processor and in another implementation example, the processor may be a multi-threaded processor. Furthermore, the processor may process a command stored in the memory or a storage device.

[0317] Moreover, the first terminal 1100 and the second terminal 1200 according to the embodiment of the present invention may preferably transmit and receive various pieces of associated information through a short-distance wireless communication scheme. For example, the first terminal 1100 and the second terminal 1200 may perform communication by using the short distance wireless communication scheme such as WiFi, Bluetooth, Zigbee, radio frequency identification (RFID), and near field communication (NFC).

[0318] Moreover, the first terminal 1100 and the second terminal 1200 according to the embodiment of the present invention may use two communication schemes in parallel. For example, the first terminal 1100 may sense and connect one or more second terminals 1200 by using the NFC communication scheme and transmit contents to the second terminal 1200 according to the WiFi communication scheme. Hereinafter, a primary configuration and an operating method of the terminal according to an embodiment of the present invention will be described.

[0319] FIG. 11 is a block diagram illustrating a primary configuration of a first terminal according to an embodiment of the present invention.

[0320] Prior to describing the primary configuration with reference to FIG. 11, the primary configuration of the terminal based on the first terminal 1100 that intends to share the contents is described for easy description, but the present invention is not limited thereto and the second terminal 1200 may be configured similarly.

[0321] Referring to FIGS. 10 and 11, the terminal according to the embodiment of the present invention may be configured to include a connection unit 1110, an input unit 1120, a control unit 1130, a storage unit 1140, and an output unit 1150.

[0322] When the respective components are described in more detail, first, the connection unit 1110 serves to sense one or more connectable second terminals 1200 and support the connection. Further, the connection unit 1110 may serve to transmit a message for establishing connection to the second terminal 1200 selected by the control unit 1130 and transmit the contents to the connected second terminal 1200 when the connection with the second terminal 1200 is completed.

[0323] In particular, the connection unit 1110 according to the embodiment of the present invention may be configured to include a communication module 1111 and a tag module 1112. The communication module 1111 is a module supporting various wired/wireless communication schemes and the tag module 1112 means a module that supports an electronic tag. Here, the electronic tag may support the short distance wireless communication schemes such as the RFID communication and the NFC communication. In particular, in the embodiment of the present invention, using the NFC communication scheme will be described as an example. The NFC is a technology as short distance wireless communication that uses a specific frequency domain which is 13.56 Mhz and transmits data with low power within a short distance (within 10 km), which has an advantage to accurately determine the will of the user, that is, whether the user selects whether to use the NFC communication.

[0324] In order to use the electronic tag, preferably, any one terminal of the first terminal 1100 and the second terminal 1200 includes a reader unit that may read a tag and any one terminal preferably includes a tag unit that may be read by the reader unit. In the embodiment of the present invention, it will be described assumed that the second terminal 1200 includes the tag unit and the first terminal includes the reader unit that may read the tag of the second terminal 1200.

[0325] Further, the connection unit 1110 according to the embodiment of the present invention may use a communication scheme for different connections and a communication scheme for transmitting the contents in parallel. For example, in order to sense one or more second terminals positioned within the predetermined radius, the connection unit 1110 may use the tag module 1112. Further, the connection unit 1110 may read identification information of the second terminal 1200 through the tag module 1112 and perform a connection process with the second terminal 1200 selected by the control unit 1130. In addition, the connection unit 1110 may transmit the contents to the second terminal 1200 connected thorough the communication module 1111.

[0326] The input unit 1120 transfers various pieces of information such as number and text information input from the user and signals input associated with various function setting and control of a function of the terminal to the control unit 1130. In particular, the input unit 1120 of the present invention may support user inputs for setting an initial connection condition to correspond to one or more second terminals 1200. Further, the input unit 1120 of the present invention may support various types of user inputs.

[0327] The input unit 1120 may include key input means such as a keyboard or a keypad, touch input means such as a touch sensor or a touch pad, voice input means, and gesture input means configured to include at least one of a gyro sensor, a terrestrial magnetic sensor, an acceleration sensor, a proximity sensor, and a camera.

[0328] Besides, the input unit 1120 may include all types of input means which is currently developed or may be developed afterwards.

[0329] The control unit 1130 which performs general control of the terminal according to the embodiment of the present invention may be configured to include at least one processor including a central processing unit (CPU)/micro processing unit (MPU), an execution memory (for example, a register and/or a random access memory (RAM)) to which at least one memory loading datum is loaded, and a bus inputting/outputting at least one datum in/from the processor and the memory in terms of hardware. Further, the control unit 1130 may be configured to include a predetermined program routine or program data which is loaded to the execution memory from a predetermined recording medium and calculated by the processor in order to a function (for example, a connection and content sharing function of the second terminal 1200) defined in the terminals 1100 and 1200 in terms of software. In other words, a component which may be processed in terms of the software among the function provided in the terminal may be determined as a function of the control unit 1130 in order to process the content sharing method according to the embodiment of the present invention.

[0330] The control unit 1130 of the present invention is functionally connected with at least one component provided to support the content sharing method according to the embodiment of the present invention. That is, the control unit 1130 is functionally connected with the connection unit 1110, the input unit 1120, the storage unit 1140, and the output unit 1150 and controls the flow of signals for supplying power to each component and performing the function of each component.

[0331] In particular, the control unit 1130 according to the embodiment of the present invention may first serve to sense one or more connectable second terminals 1200 and support the connection.

[0332] The control unit 1130 determines whether the identification information of the second terminal 1200 is registered identification information when one or more second terminals 1200 which approach within a predetermined radius are scanned through the connection unit 1110 and the identification information of the scanned second terminal 1200 is transferred from the connection unit 1110. According to a result of the determination, when the identification information of the second terminal 1200 is the registered identification information, the control unit 1130 determines the second terminal 1200 as the connectable terminal. In addition, when identification information of another second terminal 1200 is received from the connection unit 1110 within a predetermined time range, the control unit 1130 determines whether the identification information of another second terminal 1200 is the registered identification information similarly and when the identification information of another second terminal 1200 is the registered identification information, the control unit 1130 determines another second terminal 1200 as the connectable terminal. Herein, the predetermined time range may be preferably a time range between several seconds to several minutes.

[0333] In addition, the control unit 1130 determines whether the connectable second terminal 1200 exists in plural. When the plurality of connectable second terminals 1200 exist, the control unit 1130 may perform a process of selecting an optimal second terminal 1200 by comparing predetermined connection conditions and content reproduction conditions for reproducing the contents to correspond to the second terminals 1200, respectively.

[0334] In more detail, first, the control unit 1130 stores and manages information on a connection condition to correspond to the connectable second terminal 1200 in advance. Here, the connection condition may be any one of access information, positional information, service information, and specification information for establishing the connection. First, the access information may be identification information including an ID and a password for connection to the terminal. When an in-house is described as an example, the positional information as information on a location at which the second terminal 1200 is positioned may be information indicating whether the second terminal is positioned in a living room, whether the second terminal is positioned in a main room, and the like. The service information as information on a service supported by the second terminal 1200 may include, for example, information notifying that the second terminal 1200 is the smart TV when the second terminal 1200 is the smart TV. Further, the service information may include even information on a communication scheme supported to receive the contents by the second terminal 1200. For example, the service information may be information indicating whether to support the WiFi communication scheme at the time of receiving the contents, and the like. Further, the specification information as information associated with a specification of the second terminal 1200 may be, for example, information associated with hardware such as resolution information, a communication speed, and the like supported by the second terminal 1200.

[0335] While the control unit 1130 stores the information on the connection condition in advance, the control unit 1130 compares the prestored connection condition and the a content reproduction condition in a current state to correspond to each second terminal 1200 in order to select the optimal second terminal 1200 among the plurality of second terminals 1200. Herein, the content reproduction condition may content related in formation including any one of the kind, the type, and reproduction information of contents to be reproduced and current time information. Here, the kind of the contents may mean information on the kind of the contents such as a movie, a game, and the like and the type may be other information set in the contents, for example, permitted age information, information such as violence, and the like. When the contents are the movie, the reproduction information may be time information regarding a reproduced movie and when the contents are the game, the reproduction information may be information associated with the progress of the game. In addition, the time information means time information regarding a current time.

[0336] As such, the control unit 1130 selects the optimal second terminal 1200 by comparing the prestored connection condition and the content reproduction condition in the current state to correspond to each second terminal 1200 in order to select the optimal second terminal 1200 among the plurality of second terminals 1200. For example, the contents which are currently reproduced may be viewed by 19 years old or more and contents having multiple violence and further, when the current time is 11 p.m., the user will continuously enjoy the contents in a restricted environment rather than an exposed environment. In this case, the control unit 1130 may select the second terminal 1200 which is the tablet PC positioned in a small room among the plurality of second terminals 1200 as the optimal second terminal 1200.

[0337] As another example, the contents which are currently reproduced are the game contents and may be used by the whole family and when the current time is afternoon, the control unit 1130 may be positioned in the living room among the plurality of second terminals 1200 and select the second terminal 1200 which is the smart TV having an excellent specification as the optimal second terminal 1200.

[0338] Moreover, when the control unit 1130 compares the predetermined connection conditions and the content reproduction conditions to correspond to the second terminals 1200, respectively, the control unit 1130 further compares user preference information in addition thereto to select the optimal second terminal 1200. For example, when the user uses the tablet PC more frequently than the smart TV in usual, the control unit 1130 may select the second terminal 1200 corresponding to the tablet PC as the optimal second terminal 1200.

[0339] Then, the control unit 1130 may transmit a message defined for establishing the connection to the selected second terminal 1200. In this case, the control unit 1130 may transmit the defined message including the contents. In particular, the control unit 1130 according to the embodiment of the present invention may transmit the message including only contents regarding residual parts other than the content part which is currently reproduced up to now.

[0340] Here, the defined message may be, for example, an NDEF message supported in the NFC communication scheme. The NDEF message will be described with reference to FIG. 12.

[0341] FIG. 12 is an exemplary diagram for describing a message defined according to the embodiment of the present invention.

[0342] Referring to FIG. 12, the NDEF message according to the embodiment of the present invention includes one or more NDEF records. The NDEF record is a part in which substantial data are stored and includes information on the content which is currently reproducing in the embodiment of the present invention. Further, the NDEF record may be implemented by items such as a record header, a type length, a payload length, an ID length, a type, an ID, and a payload.

[0343] The items constituting the NDEF record will be defined as follows in more detail.

	TABLE 1

[0344] Referring back to FIG. 11, furthermore, the control unit 1130 according to the embodiment of the present invention may transmit only the remaining contents except for the contents which are reproduced up to now in the NDEF message when the NDEF message is transmitted to the second terminal 1200.

[0345] For example, the content is a content for a movie of about 2 hours, and when the movie of 1 hour is reproduced up to now, the terminal does not transmit all the contents to be included in the NDEF message to the selected second terminal 1200, but may transmit only the content for the remaining 1 hour to be included in the NDEF message.

[0346] In order to support the aforementioned operation, the control unit 1130 of the present invention may be constituted by including a connection control module 1131 and a content control module 1132. The connection control module 1131 serves to detect the plurality of second terminals 1200 and support a connection process with any one second terminal 1200 which is optimally selected as described above. The content control module 1132 serves to transmit the content which is currently reproducing to the connected second terminal 1200.

[0347] The storage unit 1140 may temporarily store various data generated while executing an application program including application program required for a functional operation according to the embodiment of the present invention. Particularly, the storage unit 1140 according to the embodiment of the present invention may store terminal identification information 1141 on one or more second terminals 1200 and a connection condition 1142 corresponding to the terminal identification information 1141. Further, various information related with the content may be stored.

[0348] The storage unit 1140 may largely include a program area and a data area. The program area stores related information for driving the terminal such as an operation system (OS) for booting the terminal. The data area is an area where data generated according to a use of the terminal are stored and may store the terminal identification information 1141, the information on the connection condition 1142, and the information on the content as described above. The storage unit 1140 may be constituted by including a storage medium such as a flash memory, a hard disk, a multimedia card micro type memory (for example, an SD or XD memory, and the like), an RAM, and a ROM.

[0349] The output unit 1150 outputs information on a series of operation states and operation results generated while the terminal executes the function. The output unit 1150 may be constituted by including a display module and a sound source output module. The display module may constituted by a liquid crystal display (LCD), a thin film transistor LCD (TFT-LCD), an organic light emitting diode (OLED), a light emitting diode (LED), an active matrix organic LED (AMOLE), a flexible display, and a 3 dimension display, and the like. Further, among the displays, some displays may be configured as a transparent or optical transmissive type so as to view the outside through some displays. This is constituted by a transparent display type including a transparant OLED (TOLED).

[0350] As such, main constituent elements of the terminal will be described with reference to FIG. 11. However, constituent elements illustrated in FIG. 11 are not required constituent elements and the terminal may be implemented by more constituent elements than the constituent elements illustrated and may be implemented by less constituent elements therethan. For example, when the terminal is implemented by a set-top box, the output unit 1150 may be omitted.

[0351] Further, positions of the main constituent elements of the terminal illustrated in FIG. 11 may be changed in any degree for convenience or for other reasons. Further, as the modules configuring the control unit 1130, only the connection control module 1131 and the content control module 1132 are illustrated, but the modules are not limited thereto, and the control unit 1130 may be constituted by various modules performing various functions.

[0352] Hereinabove, the main configuration and operation method of the terminals 1100 and 1200 according to the embodiment of the present invention are described.

[0353] Hereinafter, a content sharing method according to an embodiment of the present invention will be described with reference to FIGS. 13 to 16.

[0354] Prior to the description, as described above, it is described under the assumption that the first terminal 1100 is a terminal which requests the content to be continuously reproduced by transmitting the content while reproducing to the second terminal 1200 while the content is reproducing and the second terminal 1200 receives the content from the first terminal 1100 and is a terminal which may subsequently reproduce a next part after the first terminal 1100 reproduces the content.

[0355] FIG. 13 is a flowchart illustrating a content sharing method according to a fourth embodiment of the present invention.

[0356] Referring to FIGS. 10 to 13, the content sharing method according to the embodiment of the present invention first verifies one or more second terminals 1200 to which a first terminal 1100 is connectable for content sharing (S1310). As the verified result, in the case where one or more connectable second terminals 1200 exist in plural (S1320), the first terminal 1100 verifies a predetermined connection condition corresponding to the plurality of second terminals 1200.

[0357] Thereafter, the first terminal 1100 compares the verified connection condition of the plurality of second terminals 1200 and a content reproduction condition for content reproducing to select an optimal second terminal 1200 (S1340) and establish connection with the selected second terminal 1200 (S1350).

[0358] The content sharing method according to the embodiment of the present invention will be described in more detail.

[0359] FIG. 14 is a flowchart illustrating a content sharing method according to a fifth embodiment of the present invention.

[0360] Referring to FIGS. 10 and 14, in order to detect one or more second terminals 1200 which are connectable with the first terminal 1100 to share the content, one or more second terminals 1200 positioned within a predetermined radius are scanned (S1405), and when a normal scanning process is performed (S1410), the second terminal 1200 transmits identification information capable of identify the second terminal 1200 to the first terminal 1100 according to the scanning process (S1415).

[0361] The scanning process may be performed through a short range wireless communication scheme as described above. In more detail, when a distance between the first terminal 1100 and the second terminal 1200 is positioned within the predetermined radius, the first terminal 1100 and the second terminal 1200 may transmit and receive information according to a supportable communication scheme, and the first terminal 1100 may read the identification information of the second terminal 1200. For example, when the first terminal 1100 and the second terminal 1200 transmits and receives the information by a Bluetooth communication scheme, the first terminal 1100 may read a Bluetooth MAC address from the second terminal 1200. Further, in the case where the first terminal 1100 and the second terminal 1200 transmits and receives the information by an NFC communication scheme, when an access unit of the first terminal 1100 and an access unit of the second terminal 1200 contact or approaches each other, the first terminal 1100 may read identification information provided in a tag of the second terminal 1200.

[0362] The first terminal 1100 receiving the information verifies the scanned identification information of the second terminal 1200 (S1415) and determines whether the identification information of the second terminal 1200 is registered identification information (S1420).

[0363] When the identification information of the second terminal 1200 is the registered identification information, the first terminal 1100 verifies the second terminal 1200 as the connectable terminal (S1425).

[0364] Here, the first terminal 1100 sets a predetermined time range, and when a scanning process with another second terminal 1200 is not detected within the predetermined time, in step S1425, the verified connection of the second terminal 1200 may be immediately established.

[0365] However, a plurality of second terminals 1200 to which the identification information is received within the predetermined time or according to the scanning process, and further, when the plurality of second terminals 1200 is all connectable terminals (S1430), the first terminal 1100 verifies a predetermined connection condition in response to each second terminal 1200 (S1435).

[0366] In this case, the first terminal 1100 stores the connection condition in response to the identification information of the second terminal 1200 and verifies the corresponding connection condition according to the verified identification information of the second terminal 1200.

[0367] Here, the connection condition may be constituted by including at least one of, for example, access information, position information, service information, and specification information, as the condition for establishing the connection with the second terminal 1200. The access information may be identification information including an ID and a password for connection to the terminal. The position information as information on a position where the second terminal 1200 is positioned may be information on whether the second terminal 1200 is positioned at a living room or in a main room when describing an in-house as an example. The service information as information on a service supported by the second terminal 1200 may include information notifying a smart TV, for example, when the second terminal 1200 is the smart TV. Further, information on a communication scheme supporting for the content reception of the second terminal 1200 may be included therein. For example, information on whether a WiFi communication scheme is supported when receiving the content may be included. Further, the specification information as information related with specification of the second terminal 1200 may be, for example, information related with hardware such as resolution information and a communication velocity which is supported by the second terminal 1200.

[0368] In addition, the first terminal 1100 verifies a content reproduction condition (S1440). Here, the content reproduction condition may include content related information including any one of a content kind to be reproduced, a type, and reproduction information and current time information. Here, the content kind means information on a content kind such as a movie and a game, and the type may be other information set in the content, for example, available age information, information such as violence. The reproduction information may be time information on a reproduced movie and the like when the content is a movie, and maybe information related with game progressing and the like when the content is a game. In addition, the time information means time information on a current time point.

[0369] Furthermore, in the embodiment of the present invention, it is exemplified that the first terminal 1100 first verifies the connection condition and verifies the content reproduction condition, but the present invention is not limited thereto, and the first terminal 1100 may simultaneously verify the connection condition and the content reproduction condition or first verify the content reproduction condition.

[0370] In addition, the first terminal 1100 compares the verified connection condition and content reproduction condition (S1445) and selects an optimal terminal (S1450). For example, the content while currently reproducing may be watched over 19 years old and a content having a full of violence, and further, when the current time is 11 p.m, a user wants to subsequently view the content in a limited environment rather than an exposed environment. In this case, the first terminal 1100 may select the second terminal 1200 which is a tablet PC positioned in a small room among the plurality of second terminals 1200 as the optimal terminal.

[0371] Further, when the content while currently reproducing is a sound source, a second terminal 1200 having the most excellent specification related with the sound source reproduction among the plurality of second terminals 1200 as the optimal terminal.

[0372] The first terminal 1100 establishes the connection with the selected terminal when the optimal terminal is selected (S1455) and may transmit the content to the connected terminal. Here, the first terminal 1100 according to the embodiment of the present invention does not transmit all the contents, but may transmit only the rest of the contents except for the currently reproduced content. Further, when the same game content is stored in the first terminal 1100 and the second terminal 1200, the first terminal 1100 may transmit only the information related with the game progressing to the second terminal 1200.

[0373] Furthermore, in the embodiment of the present invention, preferably, the information may be transmitted and received by the NFC communication scheme. This will be described with reference to FIG. 15.

[0374] Referring to FIG. 15, the first terminal 1100 performs a process of scanning one or more second terminals, that is, a second terminal a 1210 and a second terminal b 1220 which are positioned in a predetermined radius (S1505 to S1510). The scanning process is performed when the distance between the first terminal 1100, the second terminal a 1210, and the second terminal b 1220 is within the predetermined range, or may be performed by contacting the access unit of the first terminal 1100 and the access units of the second terminal a 1210, and the second terminal b 1220 supporting the NFC communication scheme. To this end, each terminal may include any one of an NFC tag and a reader capable of reading the NFC tag.

[0375] In addition, as the scanning process is performed, each of the second terminal a 1210 and the second terminal b 1220 transmits the identification information capable of identifying each second terminal to the first terminal 1100. Thereafter, the first terminal 1100 determines whether the received identification information is registered identification information.

[0376] As the determined result, when the received identification information is the registered identification information, the first terminal 1100 determines the corresponding second terminal as the connectable terminal (S1525).

[0377] In addition, the first terminal 1100 determines whether connectable terminals include a plurality of terminals.

[0378] In the case of the registered connectable terminal, the first terminal 1100 verifies a predetermined connection condition to each terminal (S1535). In addition, the first terminal 1100 verifies the content reproduction condition for the current content reproduction (S1540), compares the connection condition and the content reproduction condition which are pre-set in each terminal (S1545), and selects the optimal terminal (S1550).

[0379] For example, when the second terminal a 1210 is an MP3 player, the second terminal b 1220 is a smart TV, and the content while reproducing in the first terminal 1100 is the sound source, the first terminal 1100 may select the second terminal a 1210 having the optimal specification for outputting the sound source. In addition, the first terminal 1100 transmits an NDEF message including information on the content to the second terminal a 1210 (S1555).

[0380] In this case, when the first terminal 1100 may transmit all of the contents, but reproduces the contents, the first terminal 1100 may transmit only the remaining part except for the currently reproduced content part included in the NDEF message to the second terminal a 1210.

[0381] The second terminal a 1210 receiving the remaining part verifies the content included in the NDEF message (S1560) and may reproduce the content (S1565).

[0382] As described above, according to the content sharing method according to the embodiment of the present invention, it is possible to increase user convenience by performing connection with a second terminal, in the case where identification information of the detected second terminal is identification information pre-registered in the first terminal to share the contents when a connectable second terminal is detected while the identification information is pre-registered between terminals to more easily share the contents among the terminals.

[0383] Further, it is possible to reproduce the contents under an optimal condition by selecting an optimal second terminal and performing connection with the selected second terminal by comparing a content reproduction condition for reproducing contents and a predetermined connection condition corresponding to each second terminal, when a plurality of connectable second terminals is detected.

[0384] Further, by using the NDEF message supported by the NFC communication scheme, all the contents are not transmitted when transmitting the content, but only some contents may be partially transmitted, and as a result, it is possible to more efficiently use the communication source when transmitting the content.

[0385] Furthermore, in order to use the content sharing method according to the embodiment of the present invention, the first terminal 1100 needs to pre-store the information on one or more connectable second terminals 1200.

[0386] That is, as illustrated in FIG. 16, the first terminal 1100 scans the second terminal 1200 to be connected (S1610) and may receive the terminal identification information and the connection condition information from the second terminal 1200 (S1620).

[0387] In addition, the first terminal 1100 may store the connection condition in response to the terminal identification information (S1630), and while the connection condition on one or more connectable terminals is pre-stored, the content sharing method may be used in the embodiment of the present invention.

[0388] The wireless charging equipment, the terminal, and the wireless charging system comprising the same according to the embodiment of the present invention may be prepared with a computer program, and codes and code segments configuring the computer program may easily deduced by a computer programmer in the art. Further, the corresponding computer program is stored in the non-transitory computer readable storage medium, and read and executed by the computer or the wireless charging equipment, the terminal (alternatively, user equipment) including the PRU, the service providing device, the second terminal, and the like to implement the wireless charging equipment, the terminal, and the wireless charging system comprising the same.

[0389] The non-transitory computer readable storage medium includes a magnetic storage medium, an optical storage medium, and a carrier wave medium. The computer program implementing the wireless charging equipment, the terminal, and the wireless charging system comprising the same according to the embodiment of the present invention may be stored and installed in embedded memories of the wireless charging equipment, the terminal (alternatively, the user equipment) including the PRU, the service providing device, the second terminal, and the like. Alternatively, external memories of a smart card and the like which store and install the computer program implementing the wireless charging equipment, the terminal, and the wireless charging system comprising the same according to the embodiment of the present invention may be installed in the wireless charging equipment, the terminal (alternatively, the user equipment) including the PRU, the service providing device, the second terminal, and the like through an interface.

[0390] As described above, according to the present invention, it is possible to conveniently share contents (for example, including multimedia contents, a business card, profile information, and the like) on a cloud by easily sharing information on a remote place based on a wireless charging situation and a cloud service.

[0391] Further, as described above, according to the present invention, it is possible to enlarge an application range of the wireless charging system and improve convenience of usage by transmitting sharing link information and identification information of one or more second terminals to the wireless charging equipment in a terminal, verifying the access to a corresponding second terminal in the wireless charging equipment to provide the sharing link information to the corresponding second terminal, and storing the sharing link information in the second terminal or downloading contents corresponding to the sharing link information, in the case where the terminal acquiring the sharing link information provided from the service providing device is charged in the wireless charging equipment.

[0392] Further, as described above, according to the present invention, it is possible to increase an advertisement effect and increase sales according to substantial purchase by providing a coupon usable in a corresponding store to a second terminal which is charging in the wireless charging equipment, in the case where the terminal getting a coupon provided from the service providing device is charged through the wireless charging equipment provided in the store to induce friends including the terminals to the store where the wireless charging equipment is provided.

[0393] Further, as described above, according to the present invention, it is possible to enlarge an application range of the wireless charging system and improve convenience of usage by registering a coupon usable in a store where the corresponding wireless charging equipment is installed which is provided from a terminal which is charging through the corresponding wireless charging equipment to a dedicated app installed in a second terminal in the second terminal which is charging through the wireless charging equipment.

[0394] Further, as described above, according to the present invention, it is possible to conveniently share the content stored in the first terminal, enlarge an application range of the wireless charging system, and improve convenience of usage by sharing data among a plurality of terminals which is charging through the wireless charging equipment.

[0395] Further, as described above, according to the present invention, it is possible to enhance usability by providing a method of directly exchanging mass data among the plurality of terminals which is charging through the wireless charging equipment to efficiently share information and share a file among many terminals of the same user.
