Embodiment Construction

[0066] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0067] At present, based on the rapid development of IEEE802.11 wireless local area network technology, wireless access to the Internet is becoming more and more popular among people. Many environmental places have WLAN coverage and show a rapid growth trend. However, with the increase of terminals in the wireless network, their mobility and fluctuation of data traffic will lead to large changes in the load of the entire network, and the channels used by APs will be allocated unevenly, resulting in a waste of channel resources in the entire network.

[0068] In this regard, this solution provides a wireless controller (i.e. AC, the same below), which can control the load balancing between APs, and it can flexibly select the mode of judging the lo...

Abstract

The invention discloses a wireless controller and a wireless load balancing method. According to the invention, a wireless controller is configured with relevant load balancing parameters and an AP needing load balancing is bound to a load balancing group configured in an AC; the AC collects a flow, reported by the AP regularly, of a WAN port and a received probe frame; and then the AC searches for an AP with the optimal load based on a configured threshold rule during terminal association. According to the wireless controller and the wireless load balancing method, a load mode is selected flexibly, the optimal-load AP is selected in a visible range of the terminal, and priority access of the 5-G frequency band is taken into consideration during the load balancing process, so that a properAP access is selected for the terminal effectively and a load balancing effect is realized.

Description

technical field [0001] The invention relates to the field of wireless communication, and more specifically relates to a load balancing technology for a wireless network according to terminal access conditions. Background technique [0002] At present, the coverage of wireless networks is becoming more and more common, and more and more wireless coverage adopts the network architecture of Fit AP+AC (thin AP+wireless controller), which is convenient for unified management of wireless networks. However, due to the mobile characteristics of STAs and the time-varying characteristics of wireless channels in WLAN, there will be a problem of great disparity in the load between APs, which will reduce the efficiency and performance of wireless networks, increase the risk of local network congestion, and cause poor resource utilization. [0003] Therefore, in order to improve the performance of wireless network access, it is necessary to better balance the load among APs and optimize t...
