1. being used in wireless personal local area network (WPAN) data channel the communication equipment discovery selected and the method coordinated between the first device and the second device, the method includes:

  • Used media access mechanisms based on asynchronous contention to send one group in finding channel (100) by the first and second equipment and find beacon block (101);

    Channel (100) is found by the first and second device scans;

    WithBy using media access mechanisms based on asynchronous contention exchange channel selection command frame (600) in finding channel (100), coordinate between the first and second devices, to select data channel,Wherein exchange channel selection command frame (600) including;

    First equipment asks the second equipment to perform scan channel by sending scan channel request command (600);

    Second equipment carrys out responsive channels scan request command (600) by sending ACK frame, and performs asked scanning;

    First equipment one receives ACK frame and is carried out the scan channel of its own;

    Second equipment comes to the first device report scanning result by sending scan channel response (600);

    First equipment selects data channel based on scanning result, and asks the second equipment to change to selected data channel by sending channel-change request order (600);

    WithSecond equipment by send channel-changing response command (600) accept or refuse selected by data channel.
