Abstract: The present invention relates to a method and device that may determine a service provided by a WiFi device to be connected before connecting a WiFi direct network. According to at least one embodiment of the present invention, if a service for an owner device of a wireless communication group is discovered for in the process of discovering for a service for the wireless communication group, there is the advantage that is possible to more conveniently perform the service discovery process by obtaining supported service information on each device belonging to the group. In addition, if there is a currently unavailable service in the process of discovering for the service for the wireless communication group, there is the advantage that it is possible to provide information highly necessary for a user to determine network establishment by further providing information on the unavailable service.
