Patent ID: 7991403

Claim:
A method for providing load balance to a wireless network system provided with at least one terminal device, a plurality of access points, and a network management server (NMS), the method comprising: employing the NMS to group the access points into at least one group by the NMS, the access points being pre-set individually by respective water level values corresponding to respective acceptable loads of the access points, wherein the water level values are pre-set individually with corresponding up limit values, trap up values and low limit values; each of the trap up values is a relevant intermediate value between the corresponding up limit value and the corresponding low limit value at the same water level; posing the NMS at an idle status of communication and waiting for a warning signal of a load status from any of the access points; only when a real-time load of one of the access points is not less than the respective trap up value of said one of the access points, said one of the access points sending out said warning signal; upon detecting said warning signal, employing the NMS to check the water level values of the other access points belonged to the same group of said one of the access points; and when all of the water level values of the other access points belonged to the same group of said one of the access points are not less than the water level value of said one of the access points, said NMS upgrading the water level value of said one of the access points once, so that said one of the access points is allowed to keep a higher acceptable load.
