A method performed by a wireless device in a wireless communication system is discussed. The method includes receiving, by the wireless device, broadcast signaling from a network, wherein the broadcast signaling informs that the network supports a device-to-device (D2D) related information; after receiving the broadcast signaling, transmitting, by the wireless device, a message including the D2D related information based on a change of the D2D related information to the network; receiving, by the wireless device, D2D radio resources from the network via a dedicated signaling; and performing, by the wireless device, a D2D operation based on the D2D radio resources.
