Abstract

A method for providing location information for VoIP emergency calling including: providing a location information database in operable communication with a location information server; maintaining a location information record corresponding to a physical location; associating a VoIP device with a location information record; receiving a request for the physical location of the VoIP device; and providing the physical location of the VoIP device.

Claims

1. A method for providing location information for VoIP emergency calling comprising:

providing a location information database in operable communication with a location information server;

maintaining a location information record corresponding to a physical location;

associating a VoIP device with a location information record;

receiving a request for the physical location of the VoIP device; and

providing the physical location of the VoIP device.

2. The method of claim 1, further comprising updating the location information record to reflect a change in the physical location of the VoIP device.

3. The method of claim 1, further comprising disassociating a VoIP device with an location information record when the VoIP device is disconnected from the physical location.

4. The method of claim 1, wherein the location information record comprises at least one of the following:

an Internet Protocol address field;

a network interface field;

a facility identification field;

a cable or wire identification field;

a living unit identification field; and

a living unit address field.

5. The method of claim 1, wherein the request for the physical location of the VoIP device includes an Internet Protocol address of the VoIP device.

6. The method of claim 1, further comprising adding a new location information record to the location information database corresponding to a new physical location.

7. The method of claim 1, wherein the location information database comprises a nested data structure.

8. A computer program product for providing location information for VoIP emergency calling, the computer program product comprising:

a storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for facilitating a method comprising;

providing a location information database in operable communication a with a location information server;

maintaining a location information record corresponding to a physical location;

associating a VoIP device with a location information record;

receiving a request for the physical location of the VoIP device; and

providing the physical location of the VoIP device.

9. The computer program product of claim 8, further comprising updating the location information record to reflect a change in the physical location.

10. The computer program product of claim 8, further comprising disassociating a VoIP device with an location information record when the VoIP device is disconnected from the physical location.

11. The computer program product of claim 8, wherein the location information record comprises at least one of the following:

an Internet Protocol address field;

a network interface field;

a facility identification field;

a cable or wire identification field;

a living unit identification field; and

a living unit address field.

12. The computer program product of claim 8, wherein the request for the physical location of the VoIP device includes an Internet Protocol address of the VoIP device.

13. The computer program product of claim 8, further comprising adding a new location information record to the location information database corresponding to a new physical location.

14. A system for providing location information for VoIP emergency calling comprising:

means for operating a location information database;

means for maintaining a location information record corresponding to a physical location;

means for associating a VoIP device with a location information record;

means for receiving a request for the physical location of the VoIP device; and

means for providing the physical location of the VoIP device.

15. The system of claim 14, further comprising means for updating the location information record to reflect a change in the physical location of the VoIP device.

16. The system of claim 14, further comprising means for disassociating a VoIP device with an location information record when the VoIP device is disconnected from the physical location.

17. The system of claim 14, wherein the location information record comprises at least one of the following:

an Internet Protocol address field;

a network interface field;

a facility identification field;

a cable or wire identification field;

a living unit identification field; and

a living unit address field.

18. The system of claim 14, wherein the request for the physical location of the VoIP device includes an Internet Protocol address of the VoIP device.

19. The system of claim 15, further comprising adding a new location information record to the location information database corresponding to a new physical location.
