Problems solved by technology

Under the influence of interference, the wireless access request of wireless users may be wrong, resulting in access failure and reducing the overall efficiency of wireless access
In addition, in various interference situations, in order to ensure wireless access as accurately as possible, it is usually necessary to sacrifice part of the bandwidth for anti-interference, resulting in a decrease in the capacity of the wireless access system

Embodiment 1

[0028] The present invention allocates channels by receiving the interference detection information sent by the wireless access point. This allocation method fully considers the signal interference of the wireless access point, so that the channel allocation operation is optimized. In order to better describe the present invention in detail The above-mentioned technical solution and technical features are described in Embodiment 1 of the present invention below.

[0029] see figure 1 , which shows the allocation process of the wireless local area network access channel in the embodiment of the present invention.

[0030] This example includes:

[0031] Step S101: Receive interference detection information sent by the wireless access point, where the interference detection information includes the interference direction, interference type and interference intensity received by the wireless access point;

[0032] A wireless access point is a bridge connecting a wireless LAN to...

Embodiment 2

[0042] In the above embodiment, the interference detection information of each wireless access point is collected, and the chromaticity value of each wireless access point is calculated by using the interference graph generated based on the interference detection information, and then channel allocation is implemented according to the chromaticity value. Although this embodiment weakens the influence of interference signals, in terms of overall capacity, the system capacity is not significantly improved because the channels are only allocated optimally. For this reason, the present invention provides a step of increasing the system capacity on the basis of the above embodiments. see image 3 , which shows the flow of channel allocation in Embodiment 2 of the present application. This example includes:

[0043] Step S301: Receive interference detection information sent by the wireless access point, where the interference detection information includes the interference directi...

Embodiment 3

[0056] The foregoing embodiments describe the process of channel allocation using the interference detection information sent by the wireless access point which is interfered with by itself, but does not limit the specific form of the interference detection information sent by the wireless access point, although the form of transmission does not hinder The realization of the purpose of the invention of the present invention. However, in practical applications, in order to know the interference situation of the wireless access point more accurately, usually the wireless access point will perform interference detection in real time or periodically, and then send interference detection information in real time or periodically, so that The interference graph can be generated in real time or periodically, and channel allocation can be performed based on the interference graph. This method can detect in time the deterioration of the wireless access point's new interference business,...

Description

technical field [0001] The present invention relates to the technical field of wireless local area network, and more specifically, relates to a method for allocating access channels of a wireless local area network and corresponding equipment and systems. Background technique [0002] With the development of information technology, Wireless Local Area Networks (WLAN, Wireless Local Area Networks) have been widely used in environments such as homes, enterprises, hospitals, and airports. Since the wireless local area network uses the wireless network to transmit data, it no longer depends on traditional twisted pair, optical fiber and other wired devices within the wireless local area network, and does not need complicated wiring, which greatly saves the cost of network construction compared with the limited network. [0003] Although the wireless local area network has the above advantages, limited by the scarcity of wireless resources, the signal range coverage of the wirele...
