Abstract

A system and method for updating physical address location information of a wireless device for E911 services. The updating may include determining that the current geographical coordinate location of the wireless device has moved beyond a predetermined distance from a last recorded geographical coordinate location. A physical address location associated with the current geographical coordinate location may then be updated. The physical address location may be updated in the wireless device and/or a data repository operating on a data packet network. The physical address location may be communicated to a public safety answering point (PSAP) in response to an emergency 911 call being placed.

Claims

1. A method for updating physical address location information of a wireless device for E-911 services, said method comprising:

determining a current geographic coordinate location of a wireless device in communication with a data packet communications network; and

in response to determining that the current geographic coordinate location of the wireless device has moved beyond a predetermined distance from a last recorded geographic coordinate location, determining a physical address location associated with the current geographic coordinate location by receiving current physical address location from user input or from a networked database;

storing a record on the wireless device to associate the current physical address location with the current geographic coordinate location.

2. The method according to claim 1, wherein the determining a physical address location associated with the current geographic coordinate location includes connecting to a data packet communications network to query the physical address location based on the geographic coordinate location.

3. The method according to claim 1, wherein determining the current physical address location includes querying a history of previous physical address locations of the wireless device.

4. The method according to claim 3, further comprising:

determining if the physical address location of the wireless device is in the history of previous physical address locations of the wireless device; and

determining the physical address location associated with the current geographical coordinate location, in response to determining that the physical address location of the wireless device is in not the history of previous physical address locations of the wireless device.

5. The method according to claim 3, further comprising updating a last recorded physical address location with the current physical address location in response to the physical address location being found.

6. The method according to claim 3, further comprising prompting a user of the wireless device to input the physical address location in response to determining that no physical address location is found by the query.

7. The method according to claim 1, wherein determining a current geographic coordinate location of a wireless device includes determining a current geographic location of a voice over internet protocol (VoIP) device.

8. The method according to claim 1, wherein determining the current physical address location includes determining the current physical address location in response to determining that the current geographic coordinate location of the wireless device has moved a distance beyond 100 feet.

9. The method according to claim 1, wherein the current physical address location includes a street address.

10. The method according to claim 1, further comprising communicating the current physical address location to a public safety answering point (PSAP) in response to a user dialing 911.

15. The method according to claim 3, further comprising updating a last recorded physical address location with the current physical address location in response to the physical address location being found.

11. A system for updating physical address location information of a wireless device for E-911 services, said system comprising:

a processing unit configured to;

determine a current geographic coordinate location of a wireless device in communication with a data packet communications network; and

determine, in response to determining that the current geographic coordinate location of the wireless device has moved beyond a predetermined distance from a last recorded geographic coordinate location, a physical address location associated with the current geographic coordinate location by receiving current physical address location from user input or from a networked database; and

store a record on the wireless device to associate the current physical address location with the current geographic coordinate location.

12. The system according to claim 11, wherein determining a physical address location associated with the current geographic coordinate location includes the processing unit connecting to the data packet communications network to query the physical address location based on the geographic coordinate location.

13. The system according to claim 12, wherein the processing unit, in determining the current physical address location, is further configured to query a history of previous physical address locations stored for the wireless device.

14. The system according to claim 12, wherein the processing unit is further configured to:

determine if the physical address location of the wireless device is in a history of previous physical address locations stored for the wireless device; and

determine the physical address location associated with the current geographical coordinate location, in response to determining that the physical address location of the wireless device is in not the history of previous physical address locations of the wireless device.

16. The system according to claim 12, wherein the processing unit is further configured to prompt a user of the wireless device to input the physical address location in response to determining that no physical address location is found by the query on the data packet network.

17. The system according to claim 11, wherein the wireless device is a VoIP device.

18. The system according to claim 11, wherein the current physical address location is determined in response to the processing unit determining that the wireless device has moved beyond a predetermined distance of 100 feet.

19. The system according to claim 11, wherein the current physical address location includes a street address.

20. The system according to claim 11, wherein the processing unit is further configured to communicate the current physical address location to a PSAP in response to a user dialing 911.
