1. A method of performing location registration by a remote user equipment (UE) in a wireless communication system, the method comprising:
transmitting a direct communication request message to a relay UE;
receiving, from the relay UE, a direct communication response message including location registration period information and location registration action time information in response to the direct communication request message; and
transmitting a first tracking area update (TAU) request message to a mobility management entity (MME), upon expiration of the location registration action time information,
wherein the location registration period information is applied after the location registration action time information is applied, and
wherein, after transmitting the first TAU request message, the remote UE transmits a second TAU request message after expiration of a time corresponding to the location registration period information.
