Abstract

Peer-to-peer (P2P) authorization by a mobile entity of a wireless communications system may include receiving a P2P authorization accept message from a management entity via a non-access stratum (NAS), receiving a radio resource control (RRC) P2P configuration request from a network entity, and sending an RRC P2P configuration complete message to the network entity via an access stratum. A management entity receiving a P2P authorization request message from a mobile entity may perform a P2P authorization check based on the received P2P authorization request message, and if the mobile entity is authorized, send a P2P authorization accept message to the mobile entity via the NAS. Alternatively, P2P authorization by a mobile entity may include sending a registration message including a P2P authorization request to a core network, and receiving a registration accept message from the core network that includes an initial context setup request and a P2P authorization response.
