Abstract

This application discloses systems and methods for associating the geographic location of VoIP devices and monitoring and updating these locations such that emergency personnel can be directed to a caller'"'"'s location based on the stored geographic-location information.

Claims

1. A method comprising:

receiving a session request from an Internet protocol device;

determining if the Internet protocol device is off-cycle or on-cycle based on the Internet protocol device'"'"'s registration information;

in response to determining the Internet protocol device is off-cycle, requesting location information of the Internet protocol device; and

in response to determining the Internet protocol device is on-cycle, initiating a session and allowing traffic from and to the Internet protocol device.

2. The method of claim 1, wherein requesting location information of the Internet protocol device further comprises storing the location information and then initiating the session and allowing traffic from and to the Internet protocol device.

3. The method of claim 1 further comprising:

disabling emergency services locating if the location information for the Internet protocol device is unavailable.

4. The method of claim 1, wherein the session request is executed via a session initiation protocol.

5. The method of claim 1 further including periodically querying to determine if the Internet protocol device is off-cycle and in response to determining that the Internet protocol device is off-cycle setting a flag requiring a request for location information of the Internet protocol device before initiating a next session.

6. The method of claim 1 further comprising:

receiving periodic self re-registrations from the Internet protocol device.

7. A computer program product comprising at least one computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:

a first executable portion configured to receive a session request from an Internet protocol device;

a second executable portion configured to determine if the Internet protocol device is off-cycle or on-cycle based on the Internet protocol device'"'"'s registration information;

a third executable portion configured, in response to determining the Internet protocol device is off-cycle, to request location information of the Internet protocol device; and

a fourth executable portion configured, in response to determining the Internet protocol device is on-cycle, to initiate a session and allow traffic from and to the Internet protocol device.

8. The computer program product of claim 7, wherein the third executable portion is further configured to store the location information and then initiate the session and allow traffic from and to the Internet protocol device.

9. The computer program product of claim 7, wherein the computer-readable program code portions further comprise:

a fifth executable portion configured to disable emergency services locating if the location information for the Internet protocol device is unavailable.

10. The computer program product of claim 7, wherein the first executable portion is further configured to receive the session request via a session initiation protocol.

11. The computer program product of claim 7, wherein the computer-readable program code portions further comprise:

a fifth executable portion configured to periodically query to determine if the Internet protocol device is off-cycle and in response to determining that the Internet protocol device is off-cycle to set a flag requiring a request for location information of the Internet protocol device before initiating a next session.

12. The computer program product of claim 7, wherein the computer-readable program code portions further comprise:

a fifth executable portion configured to receive periodic self re-registrations from the Internet protocol device.

13. An apparatus comprising:

a processor configured to;

receive a session request from an Internet protocol device;

determine if the Internet protocol device is off-cycle or on-cycle based on the Internet protocol device'"'"'s registration information;

request location information of the Internet protocol device in response to determining the Internet protocol device is off-cycle; and

initiate a session and allow traffic from and to the Internet protocol device in response to determining the Internet protocol device is on-cycle.

14. The apparatus of claim 13 wherein to request location information of the Internet protocol device, the processor is further configured to store the location information and then initiate the session and allow traffic from and to the Internet protocol device.

15. The apparatus of claim 13, wherein the processor is further configured to:

disable emergency services locating if the location information for the Internet protocol device is unavailable.

16. The apparatus of claim 13 wherein to receive a session request from an Internet protocol device, the processor is further configured to receive the session request via a session initiation protocol.

17. The apparatus of claim 13, wherein the processor is further configured to:

periodically query to determine if the Internet protocol device is off-cycle and in response to determining that the Internet protocol device is off-cycle to set a flag requiring a request for location information of the Internet protocol device before initiating a next session.

18. The apparatus of claim 13, wherein the processor is further configured to:

receive periodic self re-registrations from the Internet protocol device.
