Abstract: Proposed is a method for receiving a Wi-Fi service by a wireless LAN station supporting an application service platform (ASP). Specifically, the Wi-Fi service can be received through at least two connection techniques, for example, a Wi-Fi direct connection of Wi-Fi infrastructure connection may be used. The wireless LAN station having an ASP may detect information on each of the connection techniques and may be provided with the Wi-Fi service using one of the connection techniques. In addition, when a change in a communication environment or the like occurs, the connection technique may be switched and, in this case, signaling for switching the connection technique may be used.

Abstract: Disclosed are a method for constructing a docking protocol for using a docking service in a direct communication system, and an apparatus therefor. To this end, a method by which a first wireless device constructs a docking protocol with a second wireless device comprises: a step for searching for a probe; a step for searching for a service; a step for enabling the first wireless device to construct an application service platform (ASP) session with the second wireless device; and a step for enabling the first wireless device to construct a docking protocol with the second wireless device. At this point, the step for constructing the ASP session can be selectively performed according to the capability or the device type of the first wireless device or the second wireless device.

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.
