    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.
