Problems solved by technology

However, this method only achieves load balancing by controlling the association process of STAs when STAs are connected. It is a passive load balancing method, and its adjustment and convergence speed will be relatively slow.
In extreme cases, if no new

Embodiment Construction

[0026] The specific implementation of the load balancing method for the centralized wireless local area network of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] Such as figure 1 As shown, a load balancing method of a centralized wireless local area network, comprising steps:

[0028] S110. Obtain a wireless access point whose load is greater than a preset first overload threshold;

[0029] The load may be the number of user terminals (STA numbers) accessed by the AP, or / and traffic, etc.; if the load of the wireless access point is not greater than the first overload threshold, the AP is within the normal operating range and is not Do any load balancing operation, if the load of the wireless access point is greater than the first overload threshold, the AP is in the abnormal working range, the load is too large, and a load balancing operation is required;

[0030] S120. Control the wireless access point to sto...

Abstract

The invention provides a load balancing method of a concentrated-type wireless local area network and an access controller. The method includes the steps of obtaining a wireless access point with a load larger than a preset first overload threshold value, controlling the wireless access point to stop responding to an access request of a new user terminal, obtaining a candidate wireless access point in an accessed user terminal list which records information of correlated candidate wireless access points of user terminals, obtaining a new wireless access point with a load meeting a preset threshold value of the new user terminal from the candidate wireless access point, removing the user terminal from the wireless access point accessed currently and controlling the new wireless access point to have access to the user terminal. When a network topological structure is changed, loads of APs are adjusted in time, and loads in the whole network are balanced.

Description

technical field [0001] The invention relates to the technical field of wireless local area networks, in particular to a load balancing method and an access controller of a centralized wireless local area network. Background technique [0002] The 802.11 protocol group is a standard developed by the International Institute of Electrical and Electronics Engineers (IEEE, Institute of Electrical and Electronics Engineers) for wireless local area networks (WLAN), including 802.11a, 802.11b, 802.11g, 802.11n, etc. [0003] The wireless local area network is high-speed and low-cost, and can form a complementary advantage with the mobile communication network, providing the latter with high-quality indoor data service distribution technology, and has a suitable carrier-class operation mode, so the recent development is very rapid. WLAN networks generally have three architectures: autonomous architecture, centralized architecture, and distributed architecture. The characteristic of c...
