Title: METHOD AND DEVICE FOR SENDING WIRELESS LOCAL AREA NETWORK BEACON
Abstract:
Disclosed are a method and device for sending a wireless local area network beacon. The method comprises: a wireless access point receiving a data frame sent by a wireless terminal; determining a first moment according to the data frame, wherein the time interval between the first moment and a second moment is N times the beacon period of the wireless terminal, N ≥ 2, and the second moment is the moment when the wireless access point newly sends a beacon; sending a first unicast beacon to the wireless terminal at the first moment, wherein the BSSID of the first unicast beacon is the unique BSSID between the wireless access point and the wireless terminal. Zero roaming is realized when the wireless terminal roams between different APs. Additionally, since a time interval between the sending of two unicast beacons is greater than or equal to two beacon periods, the wireless access point is prevented from sending a beacon to the wireless terminal in each beacon period, thus reducing air interface time occupied by the wireless access point in sending a beacon, and reducing air interface overhead.
