摘要： A Wireless Local Area Network (WLAN) handover method is provided. The method comprises a mobile station receiving probe frames sent in a predefined time interval from a current associated access point and an adjacent access point during a preset time period. The station obtains and stores a signal strength for each access point based on the beacon frames. The station performs fuzzy processing of the signal strengths and change rates of the signal strengths to obtain fuzzy data characterizing levels of the signal strengths and the change rates. The station performs fuzzy reasoning based on the fuzzy data to obtain reasoning outputs. A target access point is determined by the station based on the reasoning outputs. The station authenticates with the target access point, and sends a re-association request frame to the target access point. Re-association is established after a re-association response frame is received by the station.
