If the second electronic device 120 searches for the first electronic device 110 that is broadcasting, it determines whether the first electronic device 110 still has a pairing credit (S33). If it is determined that the first electronic device 110 has no pairing quota, the second electronic device 120 searches whether the first electronic device 110 is broadcasting. The second electronic device 120 sends a pairing request _Am to the first electronic device 110, applying to join the pairing group (S35). If the first electronic device 110 does not agree to the pairing application A _m , it is determined whether the first electronic device 110 still has a pairing quota. If the first electronic device 110 agrees to the pairing application A _m , the first electronic device 110 executes the pairing procedure and obtains a tag T _m of the first electronic device 110 ( S37 ).

The automatic pairing method as described in claim item 10 further includes: When the connection code received by the second electronic device searches for the timeout, the second electronic device searches whether the first electronic device is broadcasting; If the second electronic device finds that the first electronic device is broadcasting, then determine whether the first electronic device still has a pairing quota; The second electronic device sends the pairing application to the first electronic device, applying to join the pairing connection group; If the first electronic device agrees to the pairing application, the first electronic device executes the pairing procedure, and sends a tag to the second electronic device by the first electronic device. The automatic pairing method according to claim 11, wherein if it is determined that the first electronic device has no pairing quota, the second electronic device searches whether the first electronic device is broadcasting. The automatic pairing method according to claim 11, wherein if the first electronic device does not agree to the pairing application, it is determined whether the first electronic device still has a pairing quota. The automatic pairing method as described in claim 10, wherein, if the pairing tag of the second electronic device does not appear in the pairing tag signal of the broadcast signal, the second electronic device searches for the first electronic The device is broadcasting. A wireless communication system with an automatic pairing mechanism for providing a first electronic device and at least one second electronic device for pairing and connection to form a group, which includes: The first electronic device continuously broadcasts a broadcast signal, wherein the broadcast signal includes a pairing information and an audio-visual information; Wherein, the first electronic device receives a pairing application sent by the second electronic device, and judges whether it has a matching quota according to the pairing information, and if it has the matching quota, executes a matching procedure to update the pairing information, the The format of the broadcast signal is composed of a control signal, a pairing information and an audio-visual information, and the format of the pairing signal is composed of a device independent identification code, a label and a pairing control signal.
