Method, equipment and network for load balancing based on frequency band in wireless local area network

Abstract

The invention provides a method, equipment and a network for load balancing based on frequency band in wireless local area network. The method comprises the steps as follows: when a wireless AC (Access Controller) is related on a wireless terminal or the wireless terminal departs from the AC, the load of a first frequency band and that of a second frequency band in a load balancing group can be obtained, wherein the load balancing group includes a plurality of APs (Access Points) with signals covering one another below the AC; the AC subtracts the load of the first frequency band from the load of the second frequency band to obtain a load difference value; and under the condition that the absolute value of the load difference value is not smaller than the load threshold, the AC indicates all the APs in the load balancing group not to reply a detection request of the first frequency band of a dual-band wireless terminal in the follow-up procedure. The method has the advantage that the phenomenon that the dual-band wireless terminal adopts a frequency band with too large load for access can be avoided, so that load balancing based on frequency band can be realized, and load balancing between frequency bands can be realized.

Description

technical field [0001] The invention relates to communication technology, in particular to a frequency band-based load balancing method for a wireless local area network, a wireless access controller and a network. Background technique [0002] The main communication frequency bands of the wireless local area network standard IEEE802.11 include: 2.4G frequency band and 5G frequency band. Among them, the 2.4G frequency band is 2.4GHz to 2.4835GHz, and IEEE 802.11b / g (hereinafter referred to as 802.11b / g) is applied to this frequency band. The 5G frequency band is 5.15GHz to 5.35GHz, and 5.725GHz to 5.825GHz, and IEEE 802.11a (hereinafter referred to as 802.11a) is applied to this frequency band. [0003] With the popularization of WLAN (Wireless Local Area Network, wireless local area network), there are more and more wireless users, many of whom use dual-band STAs that can simultaneously support 2.4G frequency band and 5G frequency band. However, because the professional k...
