Abstract: A method to manage a Radio Resource Control (RRC) connection in an evolved NodeB (eNB) in a wireless communication system supporting a Device to Device (D2D) scheme is provided. The method includes starting an inactivity timer to control a User Equipment (UE) to transition into an RRC idle state after setting up an RRC connection with the UE. The method also includes allocating a D2D resource to the UE when a resource request message to request the D2D resource for a direct communication between UEs is received from the UE. The method further includes transmitting a resource response message including information related to the allocated D2D resource to the UE and stopping the inactivity timer. The method includes releasing the allocated D2D resource and restarting the inactivity timer based on a predetermined option.
