Abstract

Methods and apparatus for mobile voice service management are described. An example method includes receiving a mobile network request for registering with a mobile network and responsive to the mobile network request, sending a response including an area identity list and an identifier indicating whether an area identified in the tracking area identity list supports a service.

Claims

1. A method of a mobility manager, the method comprising:

receiving a mobile network request for registering with a mobile network; and

responsive to the mobile network request, sending a response including an area identity list and an identifier indicating whether an area identified in the area identity list supports a service.

2. A method as defined in claim 1, wherein the service is voice over internet protocol multimedia subsystem service (VoIMS).

3. A method as defined in claim 1, wherein the service is voice over long term evolution (LTE) via generic access (VoLGA).

4. A method as defined in claim 1, wherein the network request is a TRACKING AREA UPDATE and the response is a TRACKING AREA UPDATE ACCEPT.

5. A method as defined in claim 1, wherein the network request is a ROUTING AREA UPDATE and the response is a ROUTING AREA UPDATE ACCEPT.

6. A method as defined in claim 1, wherein the network request is an ATTACH request and the response is an ATTACH ACCEPT.

7. A method as defined in claim 1, wherein the identifier indicates that the area does not support the service.

8. A method as defined in claim 1, wherein the identifier indicates that the area supports the service.

9. A method as defined in claim 1, wherein the identifier indicates whether all areas on the area identity list support the service.

10. A method as defined in claim 1, further comprising:

acquiring information about a set of areas; and

selectively storing areas that support the service in the area identity list.

11. A method as defined in claim 1, further comprising:

acquiring information about a set of areas;

selectively storing areas that support the service and a second service in the area identity list.

12. A method as defined in claim 1, wherein the area identity list is at least one of a tracking area identity list and a routing area identity list.

13. A mobility manager comprising:

a receiver to receive a mobile network request for registering with a mobile network; and

a transmitter responsive to the mobile network request, to send a response including an area identity list and an identifier indicating whether an area identified in the area identity list supports a service.

14. A mobility manager as defined in claim 13, wherein the service is voice over internet protocol multimedia subsystem service (VoIMS).

15. A mobility manager as defined in claim 13, wherein the service is voice over long term evolution (LTE) via generic access (VoLGA).

16. A mobility manager as defined in claim 13, wherein the network request is a TRACKING AREA UPDATE and the response is a TRACKING AREA UPDATE ACCEPT.

17. A mobility manager as defined in claim 13, wherein the network request is an ATTACH request and the response is an ATTACH ACCEPT.

18. A mobility manager as defined in claim 13, wherein the network request is a ROUTING AREA UPDATE and the response is a ROUTING AREA UPDATE ACCEPT.

19. A mobility manager as defined in claim 13, wherein the identifier indicates that the area does not support the service.

20. A mobility manager as defined in claim 13, wherein the identifier indicates that the area supports the service.

21. A mobility manager as defined in claim 13, wherein the identifier indicates whether all areas on the area identity list support the service.

22. A mobility manager as defined in claim 13, further comprising:

an acquirer to acquire information about a set of areas; and

an analyzer to selectively store areas that support the service in the area identity list.

23. A mobility manager as defined in claim 13, further comprising:

an acquirer to acquire information about a set of areas;

an analyzer to selectively store areas that support the service and a second service in the area identity list.

24. A mobility manager as defined in claim 13, wherein the area identity list is at least one of a tracking area identity list and a routing area identity list.

25-26. -26. (canceled)

27. A mobile station comprising:

a transmitter to send a network request; and

a receiver to receive a response to the network request including a area identity list and an identifier indicating whether an area identified in the area identity list supports a service.

28. A mobile station as defined in claim 27, further comprising a list extractor to extract the area identity list from the response.

29. A mobile station as defined in claim 28, further comprising a manager to determine whether all areas identified on the area identity list support the service based on the identifier.

30. A mobile station as defined in claim 27, wherein the area identity list is at least one of a tracking area identity list and a routing area identity list.
