Abstract

A method of registering a physical location of an Internet Protocol (IP) device with an Emergency 911 (E911) system includes subscribing to the IP device using Session Initiation Protocol (SIP), receiving a message containing physical address information associated with the IP device, and storing the physical address information in a location information repository.

Claims

1. A method of registering a physical location of an Internet Protocol (IP) device with an Emergency 911 (E911) system, comprising:

subscribing to the IP device using Session Initiation Protocol (SIP);

receiving a message containing physical address information associated with the IP device; and

storing the physical address information in a location information repository.

2. The method of claim 1, wherein storing the physical address information comprises:

determining if the physical address information is different than currently stored physical address information in the location information repository; and

storing the physical address information in the location information repository if the physical address information is different than the currently stored physical address information.

3. The method of claim 1, wherein storing the physical address information comprises:

translating the physical address information from a first format into a second format that is compatible with the location information repository.

4. The method of claim 3, wherein the first format is an ASCII format.

5. The method of claim 1, wherein storing the physical address information comprises:

communicating the physical address information to the location information repository using a Web Service and/or an E2 interface.

6. The method of claim 1, wherein the location information repository is an Automatic Location Information (ALI) database.

7. The method of claim 1, wherein subscribing to the IP device comprises:

subscribing to a SIP proxy device that is operable as a proxy for the IP device in registering the IP device with a SIP network.

8. The method of claim 7, further comprising:

providing an interactive user interface on the SIP proxy device for entering the physical address information associated with the IP device.

9. The method of claim 7, further comprising:

loading a configuration file on the SIP proxy device that contains the physical address information associated with the IP device.

10. The method of claim 1, further comprising:

providing an interactive user interface on the IP device for entering the physical address information associated with the IP device.

11. The method of claim 1, further comprising:

loading a configuration file on the IP device that contains the physical address information associated with the IP device.

12. The method of claim 1, wherein receiving the message comprises:

receiving a message containing physical address information and a SIP phone number associated with the IP device.

13. A computer program product comprising computer-readable program code embodied on a computer-readable medium, the computer readable program code being configured to carry out the method of claim 1.

14. An E911 system configured to carry out the method of claim 1.

15. A method of registering a physical location of an Internet Protocol (IP) device with an Emergency 911 (E911) system, comprising:

receiving a message containing physical address information associated with the IP device;

translating the physical address information from a first format into a second format that is compatible with a location information repository; and

communicating the physical address information to the location information repository using a Web Service and/or an E2 interface.

16. The method of claim 15, wherein the first format is an ASCII format.

17. An E911 system configured to carry out the method of claim 15.

18. An Emergency 911 (E911) system, comprising:

a location information repository; and

an E911 registrar server that is configured to subscribe to an IP device using Session Initiation Protocol (SIP), to receive a message containing physical address information associated with the IP device, and to store the physical address information in the location information repository.

19. The E911 system of claim 18, wherein the E911 registrar server is further configured to subscribe to the IP device by subscribing to a SIP proxy device that is operable as a proxy for the IP device in registering the IP device with a SIP network.

20. The E911 system of claim 18, wherein the E911 registrar server is further configured to store the physical address information in the location information repository by translating the physical address information from a first format into a second format that is compatible with the location information repository and communicating the physical address information to the location information repository using a Web Service and/or an E2 interface.
