  • 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
