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.
