Multi-homed peer-to-peer network

摘要

Techniques are provided for efficient peer-to-peer (P2P) service discovery and group formation, as well as maintenance of P2P session continuity. In one example, there is provided a method, operable by an originating user equipment (UE), that may involve transmitting a request for P2P service discovery and group formation assistance to a discovery server via a serving node over an air-interface channel. The method may involve receiving scoped information from the discovery server for participating in a P2P communication session, and establishing the P2P communication session with at least one terminating UE based at least in part on the received scoped information. The method may involve maintaining P2P communication session continuity by reverting to bearer signaling via a packet core.

主权项

1. A method for peer-to-peer (P2P) networking operable by an originating user equipment (UE), facilitated by a wireless wide area network, comprising:
transmitting a request for P2P service discovery and group formation assistance to a discovery server via a serving node over an air-interface channel; receiving scoped information from the discovery server for participating in a P2P direct communication session, wherein the scoped information identifies a subset of a plurality of UEs that are appropriate for service discovery; selecting a packet delivery network gateway based on information received from the discovery server during the P2P service discovery; establishing a new Evolved Packet System (EPS) bearer or using an existing EPS bearer to communicate with a terminating UE based on whether the originating UE and the terminating UE are serviced by a same eNodeB; and establishing, via the selected packet delivery network gateway, the P2P direct communication session with the terminating UE based at least in part on the received scoped information.
