摘要： 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.

摘要： The present invention relates to a load balancing method for a wireless local area network, which includes the following steps: initializing the load balancing group, self-organizing to select an online access point from the load balancing group as a load balancing agent center, each access point of the said balancing group managing and processing the load balance in accordance with the load level and balance optimizing policy, therefore implements the network load balance. The method of the invention improves reliability of the network load information, presents the load information from invalidly broadcasting in the wireless local area network, therefore reduces the additional overhead for managing the load balance of the wireless network, particularly in the network that having three layers switching equipment, self-organizing to select the agent center can utilize the network resource in effect, therefore managing the dynamic load balance information much more effectively, reducing the dependence on the upper server, and managing the network much more flexibly.
