METHOD AND SYSTEM FOR ESTABLISHING WIRELESS FIDELITY DIRECT(WFD) CONNECTION IN A WFD NETWORK ENVIRONMENT

摘要

The present invention provides a method and system for establishing a Wireless Fidelity(Wi-Fi) Direct(WFD) connection between Wi-Fi devices. When a user makes a request for a WFD connection, a source Wi-Fi device transmits a probe request frame with a first set of parameters on a pre-defined channel. The first set of parameters includes a Peer to Peer(P2P) Information Element(IE), persistence capability, and persistence information. Then, a destination Wi-Fi device sends a probe response frame including a second set of parameters to the source Wi-Fi device. The second set of parameters includes P2P IE including device discovery information and service discovery information, a discovery counter, and a validity timer. Furthermore, the source Wi-Fi device persistently stores the discovery information received in the probe response frame. Moreover, the source Wi-Fi device sets up a WFD connection with the destination Wi-Fi device using the discovery information.
