Claim:
A method of discovering a service in a Wi-Fi direct (WFD) network, the method comprising: 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 using a Wi-Fi protected setup (WPS) information element (IE), and wherein the WPS IE in the service discovery request frame comprises a field configured to selectively comprise a value identifying the service and a value for discovering a plurality of services supported by the second WFD device.
