Abstract

A mobile communication device is configured to use peer-to-peer communication to update presence information for the associated subscriber. Peer-to-peer communication bypass the network and reduce network overhead and reduce bandwidth consumption. The mobile communication device can also be configured to provide updated presence information to the network, whenever there is a change in presence.

Claims

1. A mobile wireless communication device, comprising:

a push-to-talk communication system configured to send and receive push-to-talk communications; and

a peer-to-peer communication system configured to communicate network administrative information for the mobile wireless communication device to other mobile communication devices.

2. The mobile wireless communication device of claim 1, wherein the network administrative information comprises presence information.

3. The mobile wireless communication device of claim 1, wherein the network administrative information comprises location information.

4. The mobile wireless communication device of claim 2, further comprising a user interface and a processor interfaced with the user interface, wherein a subscriber can input a change of presence through the user interface, and wherein the processor is configured receive the change in presence from the user interface and cause the peer-to-peer communication system to update other mobile communication devices with the change in presence information.

5. The mobile wireless communication device of claim 4, wherein the processor is further configured to update a network with the change in presence via the push-to-talk communication system.

6. The mobile wireless communication device of claim 2, wherein the peer-to-peer communication system is configured to receive updated presence information from other mobile wireless communication devices.

7. The mobile wireless communication device of claim 6, further comprising a memory configured to store the updated presence information for the other mobile communication devices.

8. The mobile wireless communication device of claim 1, wherein the peer-to-peer communication system is a short range wireless communication system.

9. The mobile wireless communication device of claim 8, wherein the short range wireless communication system is a WiFi system.

10. The mobile wireless communication device of claim 8, wherein the short range wireless communication system is a Bluetooth™

system.

11. The mobile wireless communication device of claim 8, wherein the short range wireless communication system is a wideband CDMA system.

12. The mobile wireless communication device of claim 8, wherein the short range wireless communication system is an optical communication system system.

13. The mobile wireless communication device of claim 6, further comprising a processor, wherein the processor is configured to send the updated presence information for another mobile communication device to still other mobile communication devices via the peer-to-peer communication system.

14. A method for updating presence in a mobile communication system, comprising:

receiving an change in presence indication;

communicating the change in presence via a peer-to-peer communication system; and

communicating the change in presence to a network via a push-to-talk communication system.

15. The method of claim 14, wherein the change of presence is to begin accepting push-to-talk communications, and wherein the method further comprises receiving push-to-talk communications.

16. The method of claim 15, further comprising receiving an indication the push-to-talk communications will not be received, and communicating the new change in presence via a peer-to-peer communication system.

17. The method of claim 16, further comprising communicating the new change in presence to a network via a push-to-talk communication system.

18. The method of claim 14, further comprising receiving update presence via the peer-to-peer communication system.

19. The method of claim 18, further comprising storing the updated presence information received via the peer-to-peer communication system.

20. The method of claim 18, further comprising transmitting the updated presence information received via the peer-to-peer communication system.

21. A mobile wireless communication device, comprising:

a push-to-talk means for sending and receiving push-to-talk communications; and

a peer-to-peer communication means for communicating presence information for the mobile communication device to other mobile communication devices.

22. The mobile wireless communication device of claim 21, further comprising a means for inputting a change of presence and a processing means for receiving the change in presence and causing the peer-to-peer communication means to update other mobile communication devices with the change in presence information.

23. The mobile wireless communication device of claim 22, wherein the processing means is further for updating a network with the change in presence via the push-to-talk means.

24. The mobile wireless communication device of claim 21, wherein the peer-to-peer communication means is further for receiving updated presence information from other mobile communication devices.

25. The mobile wireless communication device of claim 24, further comprising a memory configured to store the updated presence information for the other mobile communication devices.
