Abstract: Disclosed are methods for service discovery in a wireless personal area communication network. A method for service discovery, performed in a terminal, the method comprises performing a passive scan for searching a specific service based on whether to receive a frame including a specific service identifier; and, when it fails to search the specific service, performing an active scan which broadcasts a service discovery request command frame for searching the specific service. Thus, service discovery may be efficiently performed by reducing the operation complexity of the terminal and minimizing the power consumption of the terminal needed for service discovery, without support of a upper layer.
