Abstract: The present specification relates to a method for performing discovery by a neighbor awareness networking (NAN) proxy server in a wireless communication system. The method for performing discovery by a proxy server may comprise: a step in which a NAN proxy client performs registration in a NAN proxy server; and a step in which the NAN proxy server performs discovery for a first service on behalf of the NAN proxy server client, wherein information for the first service is delivered to the NAN proxy server in the process of performing registration so as to be used in the discovery, and the discovery can be performed on the basis of the type of discovery.

Abstract: A method for a neighbor aware network (NAN) according to one embodiment of the present specification comprises the steps of: allowing a first terminal to exchange device capability information regarding a scheduling scheme for data communication with a second terminal in a search window; allowing the first terminal to maintain an awake state in a paging window to receive a paging message including identification information indicating a receiving terminal (recipient) for traffic to be received from the second terminal, when a paging scheme is selected by means of the scheduling scheme; and allowing the first terminal to terminate, early, the paging window and switching from the awake state to a sleep state, when a channel evaluation indicator indicating a channel state of a wireless channel according to a signal received at a physical layer of the first terminal is idling for a predetermined threshold time.

Abstract: The present specification may provide a method for performing data exchange by NAN terminal in a wireless communication system. In this instance, the method in which the NAN terminal performs data exchange may comprises the steps of: discovering a first service by a first NAN terminal using at least one of a publish message and a subscribe message; transmitting a data request message associated with the discovered first service to a second NAN terminal by the first NAN terminal; receiving a data response message from the second NAN terminal by the first NAN terminal; and performing data exchange relating to the first service with the second NAN terminal by the first NAN terminal. In this case, the data request message may be transmitted on the basis of a data request method called by the first NAN terminal, and service protocol type information and port number information, which are returned as a return value, may be included in the data request message and may be transmitted on the basis of the data request method.

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 specification relates to a method for performing service discovery by a first terminal in a wireless communication system. Here, the method for performing service discovery by a first terminal may comprise the steps of: performing a service discovery procedure with a second terminal; and establishing a session connection with the second terminal, wherein the service discovery procedure may be performed through an mDNS on the basis of an ASP. In addition, the service discovery procedure may comprise the steps of: exchanging PTR query messages on the basis of the mDNS; and exchanging SRV and TXT query messages on the basis of the mDNS, wherein the TXT record of the SRV and TXT query message may essentially include advertisement ID information for the service.

Abstract: The present specification relates to a method for establishing, by a first device, an ASP session in a wireless communication system. The method for establishing, by a first device, an ASP session comprises the steps in which: the first device establishes, on the basis of a P2P connection method, an ASP session with a second device for a first service which is set to a first network type; the first device and the second device perform a feature capability exchange procedure; and the first device establishes an ASP session for a second service with the second device. Here, the feature capability exchange procedure may be completed when the first device transmits a feature capability request message to the second device on the basis of the established ASP session for the first service and receives a feature capability response message from the second device.
