Abstract
The invention discloses a method for wireless terminal dynamically switching window in a wireless LAN environment. The wireless LAN comprises several access points and stations which establish wireless communication connections with the access points. The stations can switch the current access window by scanning. The method characterizes in that including following steps: giving the switching window an initial value through the stations; the stations judge if there is another access point of which the signal quality is greater than that of the current access window through scanning wireless channels; if so, further judge if the stations are in a frequently handoff status, if so, the handoff judging result is not allowed to switch window; if not, the handoff judging result is allowed to switch window. The present invention can adaptively adjust the stations' switch windows according to the stations' handoff status and frequently handoff status. On one hand, the invention avoids the occurring of frequently handoff by changing the handoff conditions of the stations, increasing the access efficiency of the stations which is in the handoff status and in a wireless LAN environment, while maintaining the sensitivity of the stations which is in the handoff status, ensuring the quality of the wireless links between the stations and the access points.
