Abstract

Certain embodiments of the present disclosure relate to a method and an apparatus for managing and optimizing service discovery in a peer-to-peer (P2P) wireless network. Nodes of the P2P network advertise their capabilities to their peers in the form of services. Efficient propagation and management of node'"'"'s services to other nodes is proposed in the present disclosure.

5. The method of claim 3, wherein detecting the internal trigger comprises:

receiving a query from at least one communication device other than the second communication device.

6. The method of claim 3, wherein detecting the internal trigger comprises:

determining that the first communication device has changed location.

7. The method of claim 1, wherein the peer-to-peer connection between the first communication device and the second communication device comprises a direct device-to-device connection.

8. The method of claim 1, wherein the peer-to-peer connection between the first communication device and the second communication device comprises a multi-hop mesh network.

9. The method of claim 1, wherein at least one of the communication devices comprises a wireless device.

10. The method of claim 1, wherein the network access point comprises a base station.

11. An apparatus for wireless communication, comprising:

means for receiving, at a first communication device, a first signal from a second communication device over a peer-to-peer connection between the first communication device and the second communication device;

means for receiving, at the first communication device, a second signal from an access point of a cellular network; and

means for a location-based operation at the first communication device with respect to the second communication device based at least in part on previous location information for the second communication device and current location information for the second communication device included in the first and second signals, wherein the means for the location-based operation includes;

means for moving a session between the first communication device and the second communication device implemented over the peer-to-peer connection to a connection between the first communication device and the second communication device implemented over the cellular network;

or

means for moving a session between the first communication device and the second communication device implemented over the cellular network to the peer-to-peer connection between the first communication device and the second communication device.

12. The apparatus of claim 11, further comprising:

means for updating an advertisement of services offered by the first communication device.

13. The apparatus of claim 12, further comprising:

means for detecting an internal trigger at the first device; and

means for distributing the advertised services based on the detected internal trigger.

14. The apparatus of claim 13, wherein the internal trigger comprises a time-based trigger.

15. The apparatus of claim 13, wherein the means for detecting the internal trigger comprises:

means for receiving a query from at least one communication device other than the second communication device.

16. The apparatus of claim 13, wherein the means for detecting the internal trigger comprises:

means for determining that the first communication device has changed location.

17. The apparatus of claim 11, wherein the peer-to-peer connection between the first communication device and the second communication device comprises a direct device-to-device connection.

18. The apparatus of claim 11, wherein the peer-to-peer connection between the first communication device and the second communication device comprises a multi-hop mesh network.

19. The apparatus of claim 11, wherein at least one of the communication devices comprises a wireless device.
