Problems solved by technology

For example, if a certain interference source is busy, its adverse impact on air interface quality is greater than the sum of the impact of multiple interference sources with stronger signal strength but idler
It can be seen that the existing WLAN air interface quality estimation methods cannot accurately and comprehensively reflect the actual air interface quality, and the existing WLAN air interface quality estimation methods are not easy to reflect the interference of non-WLAN interference sources, such as microwave ovens, Bluetooth devices, etc. interference

Abstract

An embodiment of the invention discloses a WLAN air interface quality monitoring method and a device. The WLAN air interface quality monitoring method comprises the steps of obtaining background noise of a current working channel of an AP, the communication quality of the AP, the interference signal strength of other AP to the AP and the interference service amount of other AP communicated with a WLAN terminal to the AP; respectively allocating different weights for obtained parameters and uniformly converting the weights into dimensionless interference levels; adding data of converted interference levels together to obtain the interference level of the current working channel of the AP, and confirming whether the current working channel of the AP is required to be switched or not according to the interference level of the current working channel of the AP. By adopting the WLAN air interface quality monitoring method and the device, the interference magnitude in a WLAN system air interface environment can be accurately and comprehensively, and a WLAN system can conveniently and reasonably select the working channel.

Description

technical field [0001] The present invention relates to a wireless local area network, in particular to a WLAN (Wireless Local Area Network, wireless local area network) air interface quality monitoring method and device. Background technique [0002] WLAN technology is a local area network technology based on wireless transmission. Compared with wired network technology, it has the characteristics of flexibility, rapid network construction and personalization. Applying this technology to the access network field of the telecommunication network can provide users with wireless access conveniently and flexibly. This application is suitable for public places with high user mobility and data service requirements, high-end enterprise and home users, occasions where temporary network construction is required, and environments where it is difficult to use wired access. [0003] In recent years, the application of WLAN has developed rapidly, and has been widely used in homes, ente...
