Abstract
Disclosed are methods and apparatus for providing an access point for connection to the Internet. The methods may be performed using one or more user devices (e.g. smartphones or other mobile communications devices) which may be part of a residential Local Area Network or “home” network. A user device may detect that a connection to the Internet via a first access point is unavailable. This connection may be via a residential gateway. In response to the detection that Internet connectivity via the first access point is unavailable, a user device (e.g. the same or different user device) may activate a second access point (e.g. a wireless or mobile access point) to the Internet for use by other user devices. Other user devices may then connect to the Internet using this second access point. The second access point may be de-activated if Internet connectivity via the first access point is re-established.

Description
Field of the Invention
[0001] The present invention relates to providing access points for connection to the Internet.
Background of the Invention
[0002] Many user devices e.g. smartphones and other mobile communications devices, provide a “Mobile Hotspot” capability. The Mobile Hotspot capability enables a user device to function as a mobile access point to the Internet (or other network) which may be used by other user devices (e.g. other mobile communications devices) to connect to the Internet (or other network).
[0003] Typically, the Mobile Hotspot functionality of a user device has to be manually activated e.g. by a user of that user device.

Detailed Description
[0007] Embodiments of the invention provide methods and apparatus for providing an access point for connection to the Internet. The methods may be performed using one or more user devices (e.g. smartphones or other mobile communications devices) which may be part of a residential Local Area Network or “home” network. A user device may detect that a connection to the Internet via a first access point is not available (an access point being a device that, in normal operation, allows wireless devices to connect to the Internet). This connection may be via a residential gateway. In response to the detection that Internet connectivity via the first access point is not available, a user device (e.g. the same or different user device) may activate a second access point (e.g. a wireless or mobile access point) to the Internet for use by other user devices. Other user devices may then connect to the Internet using this second access point. The second access point may be de-activated if Internet connectivity via the first access point is re-established.
[0008] The user device that activates the second access point may have a capability to act as both a wireless or mobile access point and a router for the other user devices (e.g. it may have a capability to act as a Mobile Hotspot). The second access point may be provided by the user device activating this capability.
[0009] If there are multiple user devices that may provide the second access point, it may be determined which user device is to provide the second access point based on capabilities of the user devices. These capabilities may, for example, be dependent upon battery levels of the user devices, available processing power of the user devices, user specified preferences, the level of the wireless signal strength at the user devices, the cost of wireless communication of the user devices (e.g. user devices may be subscribed to different data plans with different charging characteristics), etc.
[0010] Further embodiments of the invention provide methods for connecting a user device to the Internet and user devices configured to connect to the Internet using those methods. The methods comprise, in response to a detection that Internet connectivity via the first access point is not available, a user device ascertaining that a connection to the Internet via the first access point is not available and that a connection to the Internet via a second access point is available. The second access point (e.g. a wireless or mobile access point) may be provided by a different user device and may have been activated by that different user device in response to the detection that a connection to the Internet via the first access point is not available. The user device may then connect itself to the Internet via the second access point.
[0011] In the following description, like reference numerals refer to like elements.
[0012] The following description is based on embodiments of the invention and should not be taken as limiting the invention with regard to alternative embodiments that are not explicitly described herein.
[0013] Apparatus for implementing any of the below described arrangements, and performing any of the below described method steps, may be provided by configuring or adapting any suitable apparatus, for example one or more computers or other processing apparatus or processors, and/or providing additional modules. The apparatus may comprise a computer, a network of computers, or one or more processors, for implementing instructions and using data, including instructions and data in the form of a computer program or plurality of computer programs stored in or on a machine readable storage medium such as computer memory, a computer disk, ROM, PROM etc., or any combination of these or other storage media.
[0014] It should be noted that certain of the process steps depicted in the below described process flowcharts may be omitted or such process steps may be performed in differing order to that presented below and shown in those process flowcharts. Furthermore, although all the process steps have, for convenience and ease of understanding, been depicted as discrete temporally-sequential steps, nevertheless some of the process steps may in fact be performed simultaneously or at least overlapping to some extent temporally.
[0015] Referring now to the Figures, FIG. 1 is a schematic illustration (not to scale) showing an example network 1 that will be used to describe embodiments of the present invention.
[0016] This example network 1 comprises a first user device 2, a second user device 4, a third user device 6, an access point 8, a residential gateway 10 and the Internet 12. In other embodiments, the present invention may be implemented in a different network that may comprise a different number of user devices. Also, the present invention may be implemented in a different network that may comprise one or more appropriate different types of devices instead of or in addition to any or all of those devices in the network 1 shown in FIG. 1 .
[0017] In the example network 1, the user devices 2, 4, 6, the access point 8, and the residential gateway 10 may be part of a residential Local Area Network (LAN) of a user of the user devices. This residential LAN may be referred to as a “home network”.
[0018] The terminology “user device” is used herein to refer to a personal or mobile computing device. Thus, each of the user devices 2, 4, 6 may be, for example, a smartphone, a wireless phone, a desktop personal user device, a laptop user device, a tablet user device, a mobile station, an entertainment appliance, a netbook, a game console, etc.
[0019] Each of the user devices 2, 4, 6 is connected to each of the other user devices 2, 4, 6, and to the access point 8 via a first communication link 14. The first communication link 14 is a Wi-Fi™ communications link. In other embodiments, the first communication link 14 may be a different type of communication link, e.g. an Ethernet communications link.
[0020] The access point 8 is a wireless access point or a wireless router. In addition to being connected, via the first communication link 14, to each of the user devices 2, 4, 6, the access point 8 is connected (via a second communications link 16 which may, for example, be a wired or wireless communications link) to the residential gateway 10. In other embodiments, the second communication link 16 may be a different type of communication link.
[0021] The residential gateway 10 is connected to the Internet 12 via a third communications link 18. The third communications link may, for example, be a Wide Area Network (WAN) communications link such as ADSL/ATM, PPP, Frame Relay, Cable, Metro Ethernet, etc. This WAN communications link can be realized with any type of applicable technology including wired, wireless and satellite communication technologies. The residential gateway 10 is a home networking device that is configured to act as a gateway to connect the user devices 2, 4, 6 to the Internet 12. In other embodiments, the residential gateway 10 may act as a gateway to connect the user devices 2, 4, 6 to a different WAN other than Internet 12.
[0022] In the network 1, the access point 8 functions as a wireless access point or router (for the user devices 2, 4, 6) that provides access to the residential gateway 10 and subsequently to the Internet 12. The access point 8 is hereinafter referred to as the “primary access point”.
[0023] In other words, in the network 1, connectivity to the Internet 12 is provided to each of the user devices 2, 4, 6 via the primary access point (which is provided by the access point 8 which is connected to the Internet via the residential gateway 10).
[0024] Each of the user devices 2, 4, 6 has a capability to act as a wireless or mobile access point, and a router, for devices connected to it (e.g. the other user devices). In this embodiment, each of the user devices 2, 4, 6 has a Mobile Hotspot capability (as the user devices 2, 4, 6 are connected together via a Wi-Fi™ communications link, i.e. the first communications link). In other words, each of the user devices 2, 4, 6 is able to function as a mobile access point (for each of the other user devices 2, 4, 6) to the Internet 12. In other words, each of the user devices 2, 4, 6 is able to provide Internet connectivity for each of the other user devices 2, 4, 6.
[0025] FIG. 2 is a process flow chart showing certain steps of an embodiment of a process that may be performed by the entities in the example network 1.
[0026] At step s2, via the first communication link 14, each of the user devices multicasts a “capability” message that is received by each of the other user devices 2, 4, 6, which are configured to receive multicast messages at the multicast address where the “capability” message is sent. A capability message provided (i.e. multicast or sent) by a user device may be indicative of that user device's ability, readiness, and/or willingness to act as a Mobile Hotspot provider for the other user devices. In other words, a capability message provided by a user device may be indicative of that user device's “capability level”, which may be a level that indicates that user device's relative ability, readiness, and/or willingness to act as a Mobile Hotspot provider for the other user devices. A capability message provided by a user device may, for example, indicate a battery status for that user device, available processing power that may be provided by that user device, one or more user defined preferences, the level of the wireless signal strength at the user device, the cost of wireless communication of the user device (e.g. user devices may be subscribed to different data plans with different charging characteristics), etc.
[0027] The user devices 2, 4, 6 may multicast a capability message to a designated (i.e. pre-configured) multicast address periodically, for example, every five minutes.
[0028] Thus, at step s2, each of the user devices 2, 4, 6, in effect, advertises to each of the other user devices 2, 4, 6 (which are configured to receive the multicast messages) its capability or willingness to act as a Mobile Hotspot (i.e. take on a role of Mobile Hotspot provider) for each of the other user devices 2, 4, 6. This capability advertisement may, for example, be accomplished using an extended version of Simple Service Discovery Protocol (SSDP) that is defined as part of the Universal Plug and Play (UPnP) specification.
[0029] In other embodiments, capability messages may be shared between the user devices 2, 4, 6 in a different appropriate way, e.g. they could be broadcast or shared via alternative means such as email or via Bluetooth communications.
[0030] At step s4, each of the user devices 2, 4, 6 receives, from each of the other user devices, the capability messages multicast by those other user devices 2, 4, 6.
[0031] At step s6, each of the user devices 2, 4, 6 processes the capability messages it has received from each of the other user devices 2, 4, 6.
[0032] This processing by each of the user devices 2, 4, 6 is performed such that each of the user devices 2, 4, 6 determines which user device 2, 4, 6 is the “best” device to act as a Mobile Hotspot (i.e. provide a mobile access point to the Internet 12) for each of the other user devices 2, 4, 6. For example, each of the user devices 2, 4, 6 may determined that the first user device 2 is the best device to act as a Mobile Hotspot for the other user devices 4, 6. A user device 2, 4, 6, may be determined to be the best device to act as a Mobile Hotspot based on any appropriate criteria and/or using any appropriate function (e.g. any function of one or more of the capability messages). For example, a user device 2, 4, 6 may be determined to be the best device to act as a Mobile Hotspot if it has the highest battery level, the most available processing power, or fulfils one or more user defined preferences.
[0033] In an example implementation, the capabilities multicast by each user device 2, 4, 6 are expressed as numeric values that are fed into a “cost function” (CF), e.g.
CF=x1*(battery level)+x2*(processing power)+x3*(RF signal strength)+x4*(user-defined preference)+x5*(communications cost)
where x1, x2, x3, x4 and x5 are predefined weight values.
CF=x1*(battery level)+x2*(processing power)+x3*(RF signal strength)+x4*(user-defined preference)+x5*(communications cost)
where x1, x2, x3, x4 and x5 are predefined weight values.
[0034] In this example, all user devices 2, 4, 6 may calculate the cost function that corresponds to all user devices 2, 4, 6. The best user device to act as a Mobile Hotspot may be the user device 2, 4, 6 that is determined to have the highest cost function.
[0035] The user device 2, 4, 6 which (at step s6) it is determined is the best device to act as a Mobile Hotspot is hereinafter referred to as the “best device”.
[0036] Each of the user devices 2, 4, 6 may process the capability messages it has received using the same algorithm (e.g. the “cost function” (CF) described above) that each of the other user devices 2, 4, 6 use to processes the capability messages they have received. This tends to provide that each of the user devices identify the same user device 2, 4, 6 as the best device for acting as a Mobile Hotspot.
[0037] At step s8, the best device determines whether or not connectivity to the Internet 12 via the primary access point (i.e. via the access point 8 and the residential gateway 10) is possible. For example, if at step s6 each of the user devices 2, 4, 6 determine that the first user device 2 is the best user device to act as a Mobile Hotspot, at step s8, the first user device 2 determines whether or not Internet access via the access point 8 and residential gateway 10 is possible. The determination of whether or not internet connectivity via the primary access point is possible may be performed using any appropriate process. For example, the best device may send a “ping” message, via the primary access point, to be received by a host on the Internet. If no response to the ping message is received by the best device, the best device may determine that connectivity to the Internet 12 via the primary access point is not possible. As another example, the best device may use the UPnP protocol to check if the WAN interface of the residential gateway 10 is in operable status or not (e.g. due to connectivity errors or component malfunction). In this case, the residential gateway 10 may support the UPnP protocol.
[0038] The best device may periodically determine whether or not connectivity to the Internet 12 via the primary access point is possible. For example, the best device may transmit (or attempt to transmit) a ping message to an Internet host every few minutes. Alternatively, when the UPnP protocol is used to determine the status of WLAN interface of the residential gateway 10, the best device may configure the residential gateway to notify the best device immediately after the status of WAN interface changes.
[0039] If, at step s8, it is determined that connectivity to the Internet 12 via the primary access point is possible, the process of FIG. 2 may return back to step s2.
[0040] However, if at step s8 it is determined that connectivity to the Internet 12 via the primary access point is not possible, the process of FIG. 2 may proceed to step s10.
[0041] At step s10, via the first communication link 14, the best device multicasts a “fall back activated” message to each of the other user devices 2, 4, 6. The “fall back activated” message may indicate that connectivity to the Internet 12 via the primary access point is not possible and/or that connectivity to the Internet 12 may be acquired via a mobile access point provided by the best device. In other words, the “fall back activated” message may indicate that an Internet connection may be acquired using the best device as a Mobile Hotspot.
[0042] At step s12, after multicasting the fallback activated message, the best device activates its Mobile Hotspot capability. In other embodiments, the Mobile Hotspot capability of the best device may be activated before or during transmission of the fallback activated message. By activating its mobile Hotspot capability, the best device may function as a mobile access point (for each of the other user devices 2, 4, 6) to the Internet 12. In other words, the best device may provide Internet connectivity for each of the other user devices 2, 4, 6. The access point to the Internet 12 provided by the best device (using its Mobile hotspot capability) is hereinafter referred to as the “secondary access point”.
[0043] At step s14, each of the user devices 2, 4, 6 other than the best device receives, from the best device, the fallback activated message multicast by the best device at step s10.
[0044] At step s16, each of the user devices 2, 4, 6 connect (e.g. reconnect) to the Internet 12 via the secondary access point provided by the best device. The best device may connect to Internet 12 in any appropriate way, for example, over a 3G or 4G wireless network. Each of the other user devices 2, 4, 6 (i.e. other than the best device) may connect to the Internet using the secondary access point provided by the best device (i.e. using the best device as a Mobile Hotspot).
[0045] FIG. 3 is a schematic illustration (not to scale) showing an example of how the entities of the network 1 may be connected together at step s16 of the process of FIG. 2 .
[0046] In this example, connection of the user devices 2, 4, 6 to the Internet 12 via the primary access point (i.e. via the access point 8 and the residential gateway 10) has been interrupted due to a break in the third communications link 18 (represented by an “X” in FIG. 3 ). In other examples, connection of the user devices 2, 4, 6 to the Internet 12 via the primary access point may not be possible for a different reason, e.g. because the access point 8 has failed or the communications link 16 is broken.
[0047] In this example, the first user device 2 is acting as a Mobile Hotspot (i.e. providing a mobile access point to the Internet 12) for each of the other user devices 4, 6. Thus, in this example, the first user device 2 has been determined to be the best device.
[0048] In this example, the first user device 2 (i.e. the best device) is connected to the Internet via a fourth communications link 20. The fourth communications link 20 may be a wireless communications link, e.g. a 3G or 4G data connection. Also, the second and third user devices 4, 6 are each connected to the Internet 12 using the secondary access point provided by the first user device 2 (i.e. using the first user device 2 as a Mobile Hotspot). In other words, the second and third user devices 4, 6 are each connected to the Internet 12 via the first communication link 14, the first user device 2, and the fourth communications link 20.
[0049] Returning now to the process of FIG. 2 , at step s18 the best device determines whether or not connectivity to the Internet 12 via the primary access point (i.e. via the access point 8 and the residential gateway 10) is possible. This step (i.e. step s18) may be performed in the same way as step s8 as described earlier above. For example, the best device may periodically ping the WAN IP address of the residential gateway 10 to determine if the communications link 18 is operational or not. Alternatively, the best device may use the UPnP protocol to check the status of the WAN link of the residential gateway 10, assuming the WAN is broken and interrupt connectivity to the Internet 12.
[0050] In other words, at step s18, the best device determines whether or not Internet connectivity via the primary access point has been re-established.
[0051] The best device may periodically determine whether or not connectivity to the Internet 12 via the primary access point is possible.
[0052] If, at step s18, it is determined that that connectivity to the Internet 12 via the primary access point is not possible, the process of FIG. 2 proceeds to step s20.
[0053] If at step s18 it is determined that that connectivity to the Internet 12 via the primary access point is possible, the process of FIG. 2 proceeds to step s22. Step s22 will be described in more detail later below after a description of step s20.
[0054] At step s20, it has been determined that connectivity to the Internet 12 via the primary access point is not possible and Internet connectivity continues to be provided to the user devices 2, 4, 6 via the secondary access point. In other words, the best device continues to act as a Mobile Hotspot for the other user devices 2, 4, 6. In other words, the best device may continue to connect to the Internet 12 in some way other than via the primary access point, whilst the other user devices continue to use the best as a mobile access point to the Internet 12.
[0055] After step s20, the process of FIG. 2 returns to step s18. Thus, the best device may continuously monitor Internet connectivity via the primary access point to determine when Internet connectivity via the primary access point is re-established.
[0056] At step s22, it has been determined that connectivity to the Internet 12 via the primary access point is possible (i.e. Internet 12 connectivity via the primary access point has been re-established) and the best device multicasts (e.g. via the first communication link 14) a “fall back de-activated” message that is received by each of the other user devices 2, 4, 6. The “fall back de-activated” message may indicate that connectivity to the Internet 12 via the primary access point is possible and/or that connectivity to the Internet 12 via the secondary access point should be discontinued. In other words, the “fall back de-activated” message may indicate that an Internet connection using the best device as a Mobile Hotspot should no longer be sought, and that connection to the Internet via the primary access point may be re-established.
[0057] At step s24, the best device de-activates its Mobile Hotspot capability. This may, for example, be performed after the best device has multicast the fall back de-activated message. By de-activating its Mobile Hotspot capability, the best device may no longer function as a mobile access point (for each of the other user devices 2, 4, 6) to the Internet 12. In other words, the “secondary access point” to the Internet 12 is no longer available.
[0058] At step s26, each of the user devices 2, 4, 6 other than the best device receives, from the best device, the fallback de-activated message multicast by the best device at step s22.
[0059] At step s28, each of the user devices 2, 4, 6 may connect (e.g. reconnect) to the Internet 12 via the primary access point (i.e. via the access point 8 and the residential gateway 10).
[0060] Thus, a method in which the Mobile Hotspot functionality of a user device may be triggered is provided.
[0061] The above described methods and systems may advantageously be used to monitor Internet connectivity via a primary access point.
[0062] Furthermore, if it is detected that Internet connectivity via this primary access point is no longer possible, connection to the Internet via a different secondary access point may be automatically made available (i.e. by automatically triggering the Mobile Hotspot functionality of a device).
[0063] Furthermore, not only is the Mobile Hotspot functionality of a device automatically triggered if Internet connectivity via the primary access point is no longer available, but the device of which the mobile functionality is triggered is the device that is considered to be the “best” device (of all possible Mobile Hotspot providers) for providing this Mobile hotspot service. Thus, the device that e.g. provides the most reliable connection, has the longest battery life, etc. may advantageously be selected to provide a secondary access point to the Internet.
[0064] The above described methods and systems advantageously tend to provide that user devices may still connect to the Internet, even if connection to the Internet via the preferred route is not possible.
[0065] In the above embodiments, each of the user devices may be capable of acting as a Mobile Hotspot. Thus, it may be possible that, if connection to the Internet via the primary access point is no longer possible, each of the devices may connect to the internet independently from one another (e.g. via a respective 3G or 4G wireless communications link). However, having each device connect independently to the internet may incur a greater total cost to the user or users of the user devices because several separate Internet connections would be used as opposed to only one. Thus, the above described methods and systems may advantageously reduce the cost to a user of connecting to the Internet.
[0066] Furthermore, having each device connect to the Internet via a separate and different Internet connections would tend to use the battery power of the devices faster than if, as in the above described methods and systems, only one such Internet connection is maintained. Thus, the above described methods and systems may advantageously save battery power of one or more of the user devices.
[0067] In the above embodiments, each of the user devices may connect to the access point (e.g. using a Wi-Fi connection). In this case, even if the connection to the internet is interrupted or broken (e.g. because the residential gateway fails or because the WAN link to the Internet is interrupted), the user devices may still “see” a strong signal (e.g. Wi-Fi signal) from the access point. If a user device sees such a strong signal from the access point, it may not decide to use an alternative way of connecting to the internet (e.g. via a 3G or 4G wireless communications link) even if connection to the internet via the access point (i.e. via the Wi-Fi link) is no longer possible. The above described methods and systems advantageously tend to solve this problem.
[0068] In the above embodiments, the method of FIG. 2 comprises the best device determining whether or not Internet connectivity via the primary access point is possible. However, in other embodiments, it may be determined whether or not Internet connectivity via the primary access point is possible in a different way. For example, one or more different user devices may determine whether or not Internet connectivity via the primary access point is possible instead of or in addition to the best device.
[0069] In the above embodiments, upon detection that Internet connectivity via the primary access point is not possible, the best device distributes a fallback activated message to each of the other devices. This message may indicate to the other devices that Internet connectivity via the primary access point is not possible and that Internet connectivity via the best device may be acquired. However, in other embodiments, this information (i.e. that Internet connectivity via the primary access point is not possible and that Internet connectivity via the best device may be acquired) may be ascertained by one or more of the devices in a different way.
[0070] For example, one or more of the other devices may multicast the fallback activated message as opposed to the best device. Alternatively, the fallback activated message may be sent from one device to another in a sequence. Alternatively, no fallback activated message may be sent. In this case, each device may monitor Internet connectivity via the primary access point, and once it is detected that Internet connectivity via the primary access point is no longer possible, the current best device may automatically enable its Mobile Hotspot functionality, and each of the other device may automatically re-connect to the Internet using the current best device as a mobile access point to the Internet.
[0071] In the above embodiments, upon detection that Internet connectivity via the primary access point is re-established, the best device distributes a fallback de-activated message to each of the other devices. This message may indicate to the other devices that Internet connectivity via the primary access point is possible and that the other devices may reconnect to the Internet using the primary access point. However, in other embodiments, this information (i.e. that Internet connectivity via the primary access point has been re-established) may be ascertained by one or more of the devices in a different way.
[0072] For example, one or more of the other devices may multicast the fallback de-activated message as opposed to the best device. Alternatively, the fallback de-activated message may be sent from one device to another in a sequence. Alternatively, no fallback de-activated message may be sent. In this case, each device may monitor Internet connectivity via the primary access point, and once it is detected that Internet connectivity via the primary access point has been re-established, the best device may automatically disable its Mobile Hotspot functionality, and each of the other device may automatically re-connect to the Internet using the primary access point. Alternatively, a device (e.g. the best device) may monitor Internet connectivity via the primary access point, and once it is detected that Internet connectivity via the primary access point has been re-established, the best device may automatically disable its Mobile Hotspot functionality. Each of the other devices may detect that connection to the internet via the secondary access point is not longer available and then may automatically re-connect to the Internet using the primary access point.
