Communication channel determination method, device and equipment

Abstract

The embodiment of the invention discloses a communication channel determination method, device and equipment. The method is executed by target wireless access point equipment, and comprises the following steps: if detecting that wireless access equipment is connected with the target wireless access point equipment, determining transmission performance data of the wireless access equipment, whereinthe transmission performance data is performance data when the wireless access device transmits data through a candidate channel; determining an optimal channel according to the transmission performance data and the use condition of the candidate channel; and switching the current channel connected with the target wireless access point device to the optimal channel. According to the embodiments of the present invention, the influence of the transmission performance data of the wireless access device on the process of determining the optimal channel is more comprehensively considered in the presence of the access of the wireless access device, and the optimal channel is accurately determined from the candidate channels by combining the transmission performance data and the use condition ofthe candidate channels, thereby more accurately determining the optimal channel.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a method, device, and equipment for determining a communication channel. Background technique [0002] With the continuous development of wireless local area networks, more and more offices, homes, campus interiors, and public places have begun to use wireless local area networks more. With the development of the Internet of Things, more and more smart devices are used in daily life, and more AP (Access Point, wireless access point) devices are added to the network environment. [0003] As an access point of a wireless network, an AP device has a coverage range ranging from tens of meters to thousands of meters; in high-density wireless deployment areas, the same channel is often used by different APs. When there is an overlapping area between these APs, there will be a problem of channel interference with each other. And there are channel co...

Problems solved by technology

When there is an overlapping area between these APs, there will be a problem of channel interference

And there are channel congestion problems, resulting in network speed drop, disconnection, and abnormal network operation. Therefore, in order to enable embedded devices to have a better network experience when they are used as AP access points, it is necessary to real-time in the current wireless network environment. Avoid congested channels, choose the best channel, and switch smoothly

[0004] In the current method, in a complex environment, the detection value obtained according to cca (clear channel detection technology, Clear Channel Assessment) is relatively high, so the accuracy of judging the size of channel traffic according to cca technology is low

Moreover, most mainstream algorithms will set the automatic channel of the device to three channels of 1, 6, and 11, causing most devices to be congested in channels 1, 6, and 11.

In addition, when calculating and selecting channels, most of the current solutions do not take into account the idle channel of the WIFI wireless access device, so sometimes if the wireless access device is busy, even if the AP side of the device sends out the data packets accurately and quickly, there is no guarantee The wireless access device can receive timely and correct

Moreover, the current method will take more time to wait for customer data feedback during the channel switching process, resulting in a serious packet loss rate
