Abstract: A method and apparatus for performing a state transition for Device to Device (D2D) communication are provided. The method includes determining whether D2D initiation is required, while a terminal is operating in a first or a second state defined by EPS (Enhanced Packet System) Mobility Management (EMM)-Deregistered and EPS Connection Management (ECM)-IDLE at a Non-Access Stratum (NAS) layer and Radio Resource Control (RRC)-IDLE. If the D2D initiation is required, the method includes transitioning to a third state defined by EMM-Registered and ECM/RRC-Connected and performing the D2D initiation through a mobile communication network. If a deactivation condition is satisfied or a D2D state update is completed in the third state, the method includes transitioning to a fourth state defined by EMM-Registered and ECM/RRC-IDLE, and if a state update or scheduling for D2D communication is required in the fourth state, the method includes transitioning to the third state.

Abstract: A discovery method for Device-to-Device (D2D) communication is provided. A terminal transmits a discovery service request message for D2D communication including one of application information and group information for a Proximity based Service (ProSe) to a server. The terminal receives, from the server, a discovery service key delivery message including a discovery service key corresponding to the one of the application information and the group information for a ProSe. The terminal acquires the discovery service key by decrypting the discovery service key delivery message, and performs discovery by encrypting a discovery code with the acquired discovery service key.
