Abstract

A system and method for performing a location update is disclosed. A preferred embodiment comprises transmitting a first location update transmission and receiving back a location update transmission response that is not simply an indication of success or failure. In an embodiment a redirection message is included in order to redirect the mobile station to another base station instead of simply telling the mobile station that the location update transmission has failed.

Claims

1. A method for wireless communication comprising:

receiving a location update transmission at a wireless base station; and

transmitting a location update response from the wireless base station, the location update response comprising a message, the message being other than success or failure.

2. The method of claim 1, wherein the location update response comprises a redirection message.

3. The method of claim 2, wherein the redirection message comprises a center frequency and an offset frequency.

4. The method of claim 2, wherein the redirection message comprises information regarding an available base station.

5. The method of claim 1, wherein the wireless base station is a Femto wireless base station.

6. The method of claim 5, wherein the wireless base station is a closed group Femto base station.

7. The method of claim 1, further comprising determining if the wireless base station is the most efficient base station for further transmissions based upon a load balancing determination.

8. A method for wirelessly transmitting data, the method comprising:

transmitting a first location update transmission from a mobile station; and

receiving a location update transmission response at the mobile station, the location update transmission response comprising a message free from an indication of success or failure.

9. The method of claim 8, wherein the location update transmission response comprises information on redirection.

10. The method of claim 9, wherein the information on redirection includes information on an available base station.

11. The method of claim 9, wherein the information on redirection comprises a center frequency and an offset frequency.

12. The method of claim 8, further comprising transmitting a second location update transmission from the mobile station in response to the location update transmission response.

13. The method of claim 12, wherein the second location update transmission is transmitted based on an identification in the location update transmission response.

14. The method of claim 12, wherein the second location update transmission is performed without entering into a Network Re-Entry from Idle Mode operation.

15. The method of claim 8, wherein the first location update transmission is transmitted during an idle mode.

16. A method for wirelessly transmitting data, the method comprising:

transmitting a first location update transmission from a mobile station to a first base station;

receiving a location update transmission response at the mobile station from the first base station, the location update transmission response comprising a redirect message that indicates a second base station; and

transmitting a second location update transmission from the mobile station to the second base station.

17. The method of claim 16, wherein the redirect message comprises a center frequency and an offset frequency.

18. The method of claim 16, where the transmitting a second location update transmission is performed without entering in to a Network Re-Entry from Idle Mode operation.

19. The method of claim 16, wherein the first location update transmission is transmitted during an idle mode.

20. A wireless base station comprising:

a receiver configured to receive a location update transmission; and

a transmitter configured to transmit a location update transmission response, the location update transmission response comprising a message different from a success indication and different from a failure notification.

21. The wireless base station of claim 20, wherein the location update transmission response comprises redirection information.

22. The wireless base station of claim 20, wherein the wireless base station is a Femto base station with restricted access.

23. A wireless mobile station comprising:

a transmitter configured to transmit a first location update transmission; and

a receiver configured to receive a first location update response, the first location update response comprising information indicative of a redirection.

24. The wireless mobile station of claim 23, wherein the transmitter is further configured to transmit a second location update transmission in response to the first location update response.

25. The wireless mobile station of claim 23, wherein the transmitter is configured to transmit the first location update transmission while in idle mode.
