Abstract
A method and an apparatus for service discovery in a Wi-Fi direct (WFD). The method includes: generating by a first WFD device a service discovery request frame for discovering whether a service is supported by a second WFD device in the WFD network; transmitting the generated service discovery request frame from the first WFD device to the second WFD device; and receiving at the first WFD device a service discovery response frame from the second WFD device in response to the transmitted service discovery request frame, wherein the service discovery request frame and the service discovery response frame are generated by using a Wi-Fi protected setup (WPS) information element (IE).
