Channel Automatic Selection and Switching Method and System, and Wireless Access Point

A method of switching a channel, comprising:

• performing, by an access point (AP), quality detection on a first channel to obtain a first quality detection result after a station (STA) couples with a first virtual access point (VAP) of the AP via the first channel;
• determining, by the AP based on the first quality detection result, whether the first channel needs to be switched;
• performing, by the AP, quality detection on a plurality of backup channels to obtain a plurality of second quality detection results when the first channel needs to be switched;
• determining, by the AP, a second channel from the backup channels based on the second quality detection results, wherein the second channel corresponds to a second VAP;
• instructing, by the AP, the STA to switch from the first channel to the second channel which uses a same network coupling information as the first channel;
• and
• performing, by the AP, data transmission with the STA using the second VAP via the second channel.

An electronic device, comprising:

• one or more processors;
• and
• one or more memories coupled to the one or more processors and comprising instructions that, when executed by the one or more processors, cause the electronic device to:
• perform quality detection on a first channel to obtain a first quality detection result after a station (STA) couples with a first virtual access point (VAP) of an access point (AP) via the first channel;
• determine, based on the first quality detection result, whether the first channel needs to be switched;
• perform quality detection on a plurality of backup channels to obtain a plurality of second quality detection results when the first channel needs to be switched;
• determine a second channel from the backup channels based on the second quality detection results, wherein the second channel corresponds to a second VAP;
• instruct the STA to switch from the first channel to the second channel which uses a same network coupling information as the first channel;
• trigger the AP to perform data transmission with the STA using the second VAP via the second channel.

A non-transitory computer readable storage medium having stored thereon executable instructions that, when executed by an electronic device, cause the electronic device to:

• perform quality detection on a first channel to obtain a first quality detection result after a station (STA) couples with a first virtual access point (VAP) of an access point (AP) via the first channel;
• determine, based on the first quality detection result, whether the first channel needs to be switched;
• perform quality detection on a plurality of backup channels to obtain a plurality of second quality detection results when the first channel needs to be switched;
• determine a second channel from the backup channels based on the second quality detection results, wherein the second channel corresponds to a second VAP;
• send a notification message instructing the STA to switch from the first channel to the second channel which uses a same network coupling information as the first channel;
• and
• trigger the AP to perform data transmission with the STA using the second VAP via the second channel.
