Abstract: The present specification may provide a method for performing discovery by a seeker terminal in a wireless communication system. In this instance, the method by which a seeker terminal performs discovery may comprise the steps of: transmitting a first frame associated with discovery, by the seeker terminal, to an advertiser terminal; receiving, from the advertiser terminal, a second frame in response to the first frame; and discovering a matching P2P terminal on the basis of the received second frame. The seeker terminal may transmit the first fame by operating in only a search mode, without a listen mode and a scan mode; the advertiser terminal may transmit the second frame by operating in only a listen mode: and the seeker terminal and the advertiser terminal may perform discovery in only a first channel.

Abstract: In the present specification, a method may be provided in which a NAN terminal exchanges frames in a wireless communication system. Here, the method in which a NAN terminal exchanges frames may include the steps of: transmitting a first frame, in which a first NAN terminal requests first properties information, to a second NAN terminal, and receiving a second frame for the first properties information from the second NAN terminal. Here, when the first frame is a service discovery frame, the first properties information may be set on the basis of a first field value of the first frame, and when the first frame is a GAS frame, the first properties information may be set as proxy service information.

Abstract: The present invention relates to a method for a NAN proxy client transitioning a state in a wireless communication system. Here, the method for a NAN proxy client transitioning a state may comprise the steps of: the NAN proxy client transitioning, to a NAN proxy server, a request message requesting the escrowing of a proxy service; receiving a response message from the NAN proxy server; performing registration to the NAN proxy server on the basis of the response message; and the state of the NAN proxy client transitioning. Here, if the registration to the NAN proxy server is performed, the state of the NAN proxy client can be transitioned to a first state.
