Method and system for switching channel of access point and access point

Abstract

The invention provides a method and system for switching a channel of an access point (AP) and an access point AP, wherein the method comprises the following steps: the AP increases a load value of the AP announced in a wireless local area network to be a preset high load value while determining that channel is required to be switched, wherein the high load value assures that the AP satisfies a load balancing condition; the AP forces the current STA (Mobile Terminal) accessed into the AP to go offline while a preset time length is reached or the number of mobile terminals (STA) accessed into the AP is lower than a preset number threshold; and the AP switches the channel after all STAs accessed into the AP are offline. The invention greatly reduces the situation of long-time service interruption of the STAs in the channel switching process of the AP by combining the AP channel switching with load balancing.

Description

technical field [0001] The invention relates to wireless network communication technology, in particular to a method, system and access point for channel switching of an access point. Background technique [0002] For a wireless local area network, channels are very scarce resources, and each access point (AP) can only work on a limited channel allocated to it. Since there are a large number of possible interference sources in the working frequency band of the wireless LAN, such as radar, microwave, etc., they will interfere with the normal operation of the AP. By adjusting the channel of the AP, each AP can be guaranteed to work on the optimal channel, which can only reduce and Avoid adjacent channel interference. [0003] Before the AP performs channel switching, a mobile terminal (STA) that has accessed the AP needs to be transferred to a neighbor AP. To solve this problem, there are mainly two ways in the prior art: [0004] The first method: Before the AP performs ch...

Problems solved by technology

[0006] Both of the above two methods use the forced STA offline method, which is too simple and rude. After the STA on the original channel is driven offline, it may not be able to find a neighbor AP that can be accessed, resulting in long-term service interruption.
