Abstract

A method is provided that includes participating in a peer-to-peer wireless communications network that includes a group controller for creating and ending the network and controlling access to the network by wireless stations. A member of the network receives a status indicator from the group controller indicating that the group owner is or will be no longer serving as group owner.

Claims

1. A method, comprising:

participating in a peer-to-peer wireless communications network that includes a group controller for creating and ending the network and controlling access to the network by wireless stations; and

receiving a status indicator from the group controller indicating that the group owner is or will be no longer serving as group owner.

2. The method of claim 1 wherein the wireless communications network conforms to a IEEE 802.11 standard.

3. The method of claim 1 wherein the status indicator is included in a beacon transmission.

4. The method of claim 1 further comprising reinitiating a master negotiation sequence with remaining wireless stations in the peer-to-peer wireless communications network upon receiving the status indicator.

5. The method of claim 4 wherein the master negotiation sequence includes assigning one of the remaining wireless stations the role of group owner.

6. The method of claim 1 wherein each of the wireless stations is configured to be operable as the group controller.

7. The method of claim 6 further comprising identifying a remaining one of the wireless stations as a new group owner after receipt of the status indicator.

8. The method of claim 7 further comprising periodically transmitting a beacon broadcast to identify the new group owner.

9. A wireless station, comprising:

an RF interface configured to exchange wireless signals with remote devices over peer-to-peer connections in a wireless communications network having a group controller for creating and ending the network and controlling access to the network by the remote devices; and

a processor configured to detect a status indicator from the group controller indicating that the group owner is or will be no longer serving as the group owner.

10. The wireless station of claim 9 wherein the processor is further configured to generate a status indicator when the wireless station is acting as the group controller and will no longer be serving in that role.

11. The wireless station of claim 9 wherein the RF interface conforms to a IEEE 802.11 standard.

12. The wireless station of claim 9 wherein the status indicator is included in a beacon transmission.

13. The wireless station of claim 9 wherein the processor is further configured to reinitiate a master negotiation sequence with remaining wireless stations in the wireless communications network upon receiving the status indicator.

14. The wireless station of claim 13 wherein the master negotiation sequence includes assigning one of the remaining wireless stations the role of group owner.

15. At least one computer-readable medium encoded with instructions which, when executed by a processor, performs a method including:

arranging a first wireless station to function as a group controller in a peer-to-peer wireless communications network that includes a plurality of wireless stations including the first wireless station, wherein the group controller is configured to create and end the network and control access to the network by each of the wireless stations; and

transmitting a status indicator when the first wireless station is or will be no longer functioning as the group owner.

16. The computer-readable medium of claim 15 wherein the status indicator is transmitted upon receipt of user input.

17. The computer-readable medium of claim 15 wherein the status indicator is transmitted upon detection of a failure in the first wireless station.

18. The computer-readable medium of claim 15 wherein the wireless communications network conforms to a IEEE 802.11 standard.

19. The computer-readable medium of claim 18 wherein the status indicator is included in a beacon transmission.

20. The computer-readable medium of claim 15 wherein arranging the first wireless station to function as the group controller includes periodically transmitting a beacon broadcast from the first wireless station to initiate an association process, said beacon broadcast indicating that the first wireless station is able to serve as the group owner.
