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

The embodiment of the invention discloses a WLAN air interface quality monitoring method and device. Wherein, the method includes obtaining the background noise of an AP's current working channel, the AP's own communication quality, the interference signal strength of other APs to the AP, and the interference traffic of other APs communicating with the WLAN terminal to the AP; The above parameters of the AP are assigned different weights, and are uniformly converted into a dimensionless interference level; the data converted into interference levels are added together to obtain the interference level of the current working channel of the AP, which is determined according to the interference level of the current working channel of the AP. Whether to switch the working channel of the AP. The embodiments of the present invention can more accurately and comprehensively reflect the magnitude of interference in the air interface environment of the WLAN system, and facilitate the WLAN system to select working channels more reasonably.
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.
