[0001] 1. Field of the Disclosure

[0002] The present disclosure generally relates to emergency alarm systems and Voice over Internet Protocol (VoIP) communications networks.

[0003] 2. Background Art

[0004] Voice over Internet Protocol (VoIP) communications is replacing circuit switch-based communications. A characteristic associated with VoIP communications is its simplicity with routing calls and information. VoIP communications enables flexibility that is not readily available to individuals and businesses using circuit switch-based communications. As such, it is desirable to adapt useful features to VoIP communications networks.

[0005] The present disclosure is pointed out with particularity in the appended claims. However, other features of the present disclosure will become more apparent and the present disclosure will be best understood by referring to the following detailed description in conjunction with the accompanying drawings in which:

[0006] FIG. 1 illustrates a block diagram of an emergency system in accordance with the present disclosure;

[0007] FIG. 2 illustrates a flowchart describing operation of the emergency system in accordance with the present disclosure; and

[0008] FIG. 3 illustrates a diagrammatical representation of a machine in the form of a computer system within which a set of instructions, when executed, causes the machine to perform any one or more of the methodologies in accordance with the present disclosure.

[0009] The present disclosure discloses a system for advanced Voice over Internet Protocol (VoIP) notification of an emergency in a building having a VoIP network and further having an alarm system for detecting emergencies in the building. The system includes a VoIP call management device in communication with the alarm system for being alerted to an emergency detected by the alarm system. In response to being alerted by the alarm system to an emergency in the building the VoIP call management device places a VoIP emergency call via the VoIP network to a VoIP telephone of an emergency authority user located outside of the building and the VoIP call management device places another VoIP emergency call via the VoIP network to a VoIP telephone of a non-emergency authority user located outside of the building who is to be notified of the emergency. In response to being alerted by the alarm system to an emergency in the building the VoIP call management device may further communicate a notification via the VoIP network to VoIP telephones located inside the building in order to alert users of the building to the emergency.

[0010] The present disclosure discloses a system for advanced VoIP notification of an emergency. This system includes a VoIP network associated with a building. The VoIP network has a VoIP call management device. The VoIP network further has VoIP telephones for use by building users located within the building. The VoIP network is connected to an Internet Protocol (IP) network connected to VoIP telephones for use by users located outside of the building such that the VoIP telephones for use by the building users and the users located outside of the building are connected in order for these users to communicate VoIP telephone calls to one another. This system further includes an alarm system for detecting an emergency in the building. The alarm system is in communication with the VoIP call management device. In response to detecting an emergency in the building, the alarm system directs the VoIP call management device to have the VoIP network place a VoIP emergency call to the VoIP telephone of an emergency authority user located outside of the building. In response to the VoIP network placing the VoIP emergency call to the VoIP telephone of the emergency authority user, the VoIP call management device has the VoIP network place another VoIP emergency call to the VoIP telephones of non-emergency authority users located outside of the building who are to be notified of the emergency. In response to detecting an emergency in the building, the alarm system may further direct the VoIP call management device to communicate a notification to the VoIP telephones for use by the building users in order to alert the building users of the emergency.

[0011] The present disclosure discloses a method for advanced VoIP notification of an emergency. The method includes using an alarm system to detect for emergencies in a building. In response to the alarm system detecting an emergency in the building, a VoIP emergency call is placed from a VoIP telephone of a VoIP network associated with the building to a VoIP telephone of an emergency authority located outside of the building. In response to the VoIP emergency call being placed to the VoIP telephone of the emergency authority user, another VoIP emergency call is placed to the VoIP telephones of non-emergency authority users located outside of the building who are to be notified of the emergency. In response to the alarm system detecting an emergency in the building, a notification may be communicated to VoIP telephones of the VoIP network associated with the building for alerting users of the building to the emergency.

[0012] The present disclosure discloses a computer-readable medium for advanced VoIP notification of an emergency. The medium includes instructions for using an alarm system to detect for emergencies in a building. The medium further includes instructions for placing a VoIP emergency call from a VoIP telephone of a VoIP network associated with the building to a VoIP telephone of an emergency authority located outside of the building in response to an emergency in the building being detected. The medium further includes instructions for placing another VoIP emergency call to the VoIP telephones of non-emergency authority users located outside of the building who are to be notified of the emergency in response to the VoIP emergency call being placed to the VoIP telephone of the emergency authority user. The medium may further include instructions for communicating a notification to VoIP telephones of the VoIP network associated with the building for alerting users of the building to the emergency in response to the emergency being detected.

[0013] In general, the present disclosure provides a method and system for advanced Voice over Internet Protocol (VoIP) emergency notification. The method and system provide useful features to VoIP communications networks by readily aiding both emergency authorities and those in need during an emergency situation within a locale such as a building or a campus of buildings.

[0014] The method and system facilitate action and reaction during an emergency situation in a building(s) having a standard building alarm system and a VoIP telephone network by combining the utility of the alarm system with the flexibility of the VoIP network. The method and system enable the alarm system and/or building security personnel to take control of and use the VoIP network in order to provide emergency notification to the building users in the event of an emergency in the building.

[0015] The VoIP network includes VoIP telephones for the building users to place and receive VoIP telephone calls. The VoIP network is part of a larger VoIP communications network which enables VoIP telephone calls to be placed between the VoIP telephones within the building and VoIP telephones located outside of the building.

[0016] The method and system include two functional aspects. A first functional aspect is the building alarm system and/or building security personnel being able to take control of the VoIP network of the building in the event of an emergency in the building in order to provide emergency notification to the building users via their VoIP telephones. A second functional aspect is a VoIP call management device of the VoIP network recognizing that a VoIP emergency call (such as a “911” call) has been placed to offsite emergency authorities (either by the alarm system or the building security personnel) and then routing a duplication of the emergency call to onsite security/emergency personnel and/or other affected parties (e.g., family members of a building user affected by the emergency, the building's owner, etc.). The VoIP call management device routes the duplicate emergency call to any of these recipients in either interactive or audio-only mode. The duplicate emergency call serves as a notification for its recipients to prepare for the arrival of the emergency authorities. As such, the duplicate emergency call further serves for coordinating activities between the duplicate emergency call recipients and the emergency authorities depending on the nature of the emergency.

[0017] Referring now to FIG. 1, a block diagram of an emergency system 10 in accordance with the present disclosure is shown. Emergency system 10 is generally for use with a locale such as a building 12 or a campus of buildings. Emergency system 10 includes an alarm system 14 and a VoIP telephone network 18. Alarm system 14 and VoIP network 18 are located in and are associated with building 12.

[0018] Alarm system 14 provides typical alarm functions to monitor for emergency situations in building 12. Emergency situations monitored by alarm system 14 include unauthorized building intrusions, fires in the building, distress calls placed by building users, etc. Alarm system 14 is operable for providing relief in response to an emergency situation. For example, alarm system 14 triggers a building sprinkler system to sprinkle water in building 12 in response to detecting a fire. As another example, alarm system 14 triggers visual/audible alerts to notify the building users of an emergency in building 12 in response to detecting the emergency. As a further example, alarm system 14 notifies emergency authorities in response to detecting an emergency. To this end, as will be described in greater detail below, alarm system 14 is operable with VoIP network 18 to place a VoIP “911” emergency telephone call to outside emergency authorities such as a ”911” operator. Security personnel 16 of building 12 are in communication with alarm system 14 to be apprised of any emergency situation detected by the alarm system in order to be aware of and respond to the emergency.

[0019] VoIP network 18 includes a VoIP call management device 20 and a plurality of VoIP telephones 22. Building users 24 use VoIP telephones 22 to make VoIP telephone calls with other building users and with VoIP telephone users located outside of building 12. To this end, VoIP call management device 20 connects with an Internet Protocol (IP) network 26. IP network 26 is located outside of building 12 and connects with the VoIP telephones of VoIP telephone users outside of the building. As shown in FIG. 1, VoIP telephones outside of building 12 include VoIP telephones 28 of ordinary VoIP telephone users located outside of building 12, VoIP telephones 30 of emergency authorities including a “911” operator, and VoIP telephones 32 of individuals outside of the building that are to be notified of emergencies in the building (e.g., the owner of the building, physicians of building users, family members of building users, etc.).

[0020] VoIP network 18 further includes a VoIP telephone 34 for use by security personnel 16. In the same manner that building users 24 use their VoIP telephones 22 to make VoIP telephone calls with other VoIP telephone users inside and outside of building 12, security personnel 16 use VoIP telephone 34 to make VoIP telephone calls to other VoIP telephone users. For instance, security personnel 16 use VoIP telephone 34 to make VoIP telephone calls via VoIP network 18 to VoIP telephones 22 of building users 24. In response to detecting an emergency in building 12 and/or in response to being apprised of an emergency by alarm system 14, security personnel 16 use VoIP telephone 34 to place a VoIP “911” emergency telephone call via VoIP network 18 to VoIP telephone 30 of a “911” operator for receipt by emergency authorities (such as the fire and police departments). Similarly, alarm system 14 is in communication with VoIP call management device 20 to automatically place a VoIP “911” emergency telephone call via VoIP network 18 to VoIP telephone 30 of the “911” operator in response to detecting an emergency situation.

[0021] Emergency system 10 generally includes two functional aspects. A first functional aspect is the ability of alarm system 14 and/or security personnel 16 to take control of VoIP network 18 based on the nature of an emergency in building 12. A second functional aspect is the ability of VoIP call management device 20 to recognize that a VoIP “911” emergency telephone call has been placed to outside emergency authorities (either by alarm system 14 or security personnel 16) and then route a duplication of the emergency call to VoIP telephone 34 of security personnel 16 and/or to VoIP telephones 32 of parties having an interest in the emergency (e.g., family members of building users affected by the emergency, the building's owner, etc.).

[0022] With respect to the first functional aspect, alarm system 14 and/or security personnel 16 take control of the entire (or a subset of the entire) VoIP network 18 based on the nature of an emergency in building 12 in order to communicate with VoIP telephones 22 to provide an emergency notification to building users 24. More particularly, alarm system 14 and/or security personnel 16 interact with VoIP call management device 20 in order to have the VoIP call management device provide an emergency notification to building users 24 via VoIP telephones 22.

[0023] Several manifestations of the emergency notification exist. For example, VoIP call management device 20 rings VoIP telephones 22 of building users 24 in order to provide the emergency notification to the building users. As another example, VoIP call management device 20 places VoIP telephones 22 not currently involved in calls in a speaker phone mode to announce an emergency and give instructions (i.e., forming a public address system). As another example, VoIP call management device 20 breaks into ongoing calls being made by VoIP telephones 22 to provide the emergency notification to building users 24.

[0024] Alarm system 14 connects to VoIP call management device 20 in order to take control of VoIP network 18 and have the VoIP call management device provide an emergency notification to building users 24 via their VoIP telephones 22 in response to the alarm system detecting an emergency. Security personnel 16 have access to an emergency interface of VoIP network 18 in order to take control of the VoIP network and have VoIP call management device 20 provide an emergency notification to building users 24 via their VoIP telephones 22 in response to an emergency. For instance, VoIP telephone 34 of security personnel 16 includes an emergency interface 36. Emergency interface 36 is in communication with VoIP call management device 20 in order to enable security personnel 16 to interact with the VoIP call management device and take control of VoIP network 18 for providing the emergency notification to building users 24 via VoIP telephones 22. VoIP telephones 22 of building users 24 may also be configured with the emergency interface. The emergency interface may also be embodied as a web-based or standalone application on a computer 38 that is communicable with VoIP call management device 20.

[0025] As such, via an emergency interface of VoIP network 18, security personnel 16 notify affected building users 24 via their VoIP telephones 22 of an emergency and are able to give warnings/emergency instructions to affected building users in response to being apprised of the emergency. Likewise, alarm system 14 notifies affected building users 24 via their VoIP telephones 22 of an emergency and is able to give warnings/emergency instructions to affected building users in response to detecting the emergency. In the latter case, emergency system 10 is automated by a direct emergency interface between alarm system 14 and VoIP call management device 20 in order to reduce the load on security personnel 16 as well as to handle after-hours conditions where security personnel may not be present at building 12.

[0026] The type of warnings/emergency instructions provided by alarm system 14 and security personnel 16 may be predetermined based on different types of emergencies. As such, the emergency interface allows customized broadcasting ability based on either predefined emergency scenarios or scenarios chosen by security personnel 16 in order for quicker and more effective notification to building users 24.

[0027] With respect to the second functional aspect, VoIP call management device 20 recognizes that a VoIP “911” emergency telephone call has been placed to VoIP telephone 30 of emergency authorities (either by alarm system 14 or security personnel 16) and then routes a VoIP duplication of the emergency call to VoIP telephone 34 of security personnel 16 and/or to VoIP telephones 32 of parties interested in the emergency (e. g., family members of building users affected by the emergency, the building's owner, etc.). VoIP call management device 20 routes the duplicate VoIP emergency call to VoIP telephones 32, 34 in either interactive or audio-only mode. The duplicate emergency call serves as a notification for its recipients to prepare for the emergency authorities. As such, the duplicate emergency call further serves for coordinating activities between the duplicate emergency call recipients and the emergency authorities (such as fire and police authorities) depending on the nature of the emergency.

[0028] Accordingly, the second functional aspect allows for automatic recognition of a VoIP emergency telephone call placed by either alarm system 14 or security personnel 16 to VoIP call management device 20 for receipt by VoIP telephones 30 of emergency authorities (i.e., the “911” operator) via VoIP network 18. Upon recognition, VoIP call management device 20 routes the VoIP emergency call normally to VoIP telephone 30 of emergency authorities, but also routes. a duplication of the emergency call (i.e., a second VoIP emergency call) to a VoIP telephone 32 of each party having an interest in the emergency (as well as to VoIP telephone 34 of other security personnel in building 12 if desired). To this end, VoIP call management device 20 has a list of parties to be notified of emergencies in building 12 and the telephone numbers of their associated VoIP telephones 32, 34. VoIP call management device accesses this list and routes the second emergency call to VoIP telephone 32, 34 of each party to be notified of an emergency.

[0029] The list of interested parties may be correlated with different emergency types. As such, VoIP call management device 20 routes the second emergency call to only a subset of the interested parties on the list depending on the type of emergency. In addition to other security personnel of building 12, such interested parties include offsite security personnel, personal physicians, the building owner and operator, family members of building users, etc.

[0030] The duplicate emergency call to each interested party conferences the interested parties into the original VoIP emergency call placed to VoIP telephone 30 of emergency authorities. This conference call can either be audio-only to serve as notification or can be a live conference to allow for coordination and facilitation with emergency authorities.

[0031] A benefit of emergency system 10 includes increasing the utility of current emergency systems and adding improved ability for coordination among building security personnel, emergency authorities, and other interested parties.

[0032] Referring now to FIG. 2, with continual reference to FIG. 1, a flowchart 40 describing operation of emergency system 10 is shown. The operation of emergency system 10 begins with alarm system 14 and/or security personnel 16 detecting an emergency in building 12 as shown in block 42. In response to the emergency, alarm system 14 (automatically) and/or security personnel 16 (manually) place a VoIP “911” emergency telephone call to VoIP telephone 30 of emergency authorities via VoIP network 18 as shown in block 44. In response to the emergency, alarm system 14 (automatically) and/or security personnel 16 (manually) take control of VoIP network 18 in order to provide emergency notification and instructions to building users 24 via VoIP telephones 22 as shown in block 46. VoIP call management device 20 recognizes that a VoIP “911” emergency telephone call has been placed to emergency authorities via VoIP network 18 and then routes a duplicate VoIP emergency call to VoIP telephones 32, 34 of other parties to be notified of the emergency as shown in block 48.

[0033] Referring now to FIG. 3, a diagrammatic representation of a machine in the form of a computer system 600 is shown within which a set of instructions, when executed, may cause the machine to perform any one or more of the methodologies discussed herein. In some embodiments, the machine operates as a standalone device. In some embodiments, the machine may be connected (e.g., using a network) to other machines. In a networked deployment, the machine may operate in the capacity of a server or a client user machine in server-client user network environment, or as a peer machine in a peer-to-peer (or distributed) network environment.
