Load balancing method for wireless network system

Abstract

A method for providing load balance to a wireless network system is disclosed, wherein a network management server (NMS) is used to group a plurality of access points into a plurality of groups. Each of the access points is pre-set with a plurality of water level values corresponding to an acceptable load thereof, and each of the water level values is pre-set with a corresponding trap up value. Only when the real-time load of one of the access points is up to the trap up value thereof, the access point actively sends a signal of a corresponding load status thereof to the NMS. Meanwhile, the NMS checks the water level values of the other access points belonged to the same group of the access point. If all of the water level values of the other access points belonged to the same group of the access point are not less than the water level value of the access point, the water level value of the access point which has the real-time load up to the trap up value thereof is upgraded once so as to allow the access point to keep a higher acceptable load. Thus, it is unnecessary for each of the access points to continuously broadcast its corresponding load status so as to prevent from occupying the bandwidth thereof and thus to improve the overall efficiency of the wireless network system.
