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.

Abstract translation: 公开了一种用于向无线网络系统提供负载平衡的方法，其中使用网络管理服务器（NMS）将多个接入点分组成多个组。 每个接入点都预先设置有与其可接受负载对应的多个水位值，并且每个水位值都以相应的上升值预先设定。 只有当其中一个接入点的实时负载达到其上升值时，接入点才能将其相应负载状态的信号主动发送给网管。 同时，NMS检查属于同一组接入点的其他接入点的水位值。 如果属于接入点的同一组的其他接入点的所有水位值都不小于接入点的水位值，则具有实时加载的接入点的水位值 对其上升值进行一次升级，以允许接入点保持更高的可接受负载。 因此，每个接入点不必连续地广播其对应的负载状态，以防止占用其带宽，从而提高无线网络系统的整体效率。

Abstract: A method for automatically allocating channels of a wireless network system comprises the steps of: actuating one of access points (APs) for collecting channel status information, such as channel numerals and Received Signal Strength Incident (RSSI), of the other of the access points near by that access point; calculating an accumulated RSSI value of each of the access points according to the collected channel numerals and the RSSI value via a Network Management Server (NMS); calculating the accumulated RSSI value of each of the access points by weighting to obtain a weighted RSSI value thereof; and switching an operation channel of the actuated access point into the better channel having a relatively lower weighted RSSI value for improving the overall efficiency of the wireless network system. Furthermore, the method for automatically allocating channels can be used to periodically monitor the channel status of the channel corresponding to each of the access points, so as to actively fine-adjust the channel of that access point or to change a monitor period.
