Abstract:
The present invention relates to a wireless communication system and, more particularly, to a method and apparatus for performing a proximity service in a wireless communication system. According to one embodiment of the present invention, a method for allowing a first Internet protocol multimedia subsystem (IMS) terminal to perform a proximity service (ProSe) in a wireless communication system can comprise the steps of: allowing the first IMS terminal to transmit a first session initiation protocol (SIP) message containing ProSe communication request information to a second IMS terminal through a network node; and receiving a second SIP message containing ProSe communication response information from the second IMS terminal through the network node.
