Wireless local area network access point scheduling method, controller, access points and system

Abstract

The present invention relates to a method for scheduling an access point of a wireless local area network. The method comprises: within a current scheduling cycle of a network running state, a first controller receiving statistical performance data reported by a plurality of access points in a first access point cluster within the last scheduling cycle, wherein the first access point cluster comprises the first controller and a plurality of access points connected to the first controller; according to statistical performance information, generating a scheduling solution of the plurality of access points within the next scheduling cycle; and broadcasting the scheduling solution to the plurality of access points, for configuring a sending parameter within the next scheduling cycle by the plurality of access points within the current scheduling cycle according to the scheduling solution, and communicating with a user equipment according to the sending parameter, wherein the sending parameter comprises an antenna direction, an upper limit value of a transmission power, and a threshold value of an estimated parameter of an idle channel. By means of the embodiments of the present invention, that the effect of different access points on other access points when communicating with the user equipment (UE) is reduced is realized in a local area network with a plurality of access points, thereby improving the access rate of the wireless local area network.

Description

technical field [0001] The invention relates to the communication field, in particular to a wireless local area network access point scheduling method, controller, access point and system. Background technique [0002] Wireless local area network (Wireless Local Area network, WLAN) is more and more widely used, and a single access point (Access Point, AP) WLAN cannot meet the access requirements of user equipment in a large coverage area. In the WLAN of the access point, multiple APs belonging to the same WLAN work on the same channel frequency, such as figure 1 It is shown that when different user equipments communicate with APs concurrently, due to wireless signal collisions, the bandwidth allocated to each user equipment may not increase due to the increase in the number of APs, but may decrease instead. [0003] In order to reduce the impact on user equipment communicating with other APs when a single user equipment communicates with an AP, such as figure 2 As shown, ...

Problems solved by technology

However, in a WLAN system with multiple APs, it will still have a great impact on the concurrent communication of user equipment within the range of other APs, which will affect the network throughput of the wireless LAN with multiple APs.
