Method for controlling AP connection priority under WiFi environment

Abstract

The invention relates to the field of wireless communication, and discloses a method for controlling AP connection priority under a WiFi environment. By means of the method, more optimized WiFi connection selected is provided for users. Twelve recommended priority levels are defined according to the severity degree of the interference problem in the WiFi practical environment, the recommended priority levels are used for guiding a current WiFi system to select appropriate AP trigger connection, APs of the twelfth priority level, the eleventh priority level, the tenth priority level, the ninth priority level, the eighth priority level and the seventh priority level can be used for normal connection communication, the specific priority levels are evaluated according to communication quality, the sixth priority level and the fifth priority level represents APs where normal connection can be conducted but communication quality problems happen, the specific priority levels are classified according to influences on the communication quality, the fourth priority level, the third priority level, the second priority level and the first priority level represent APs where connection processes are abnormal, and the specific priority levels are classified according to abnormity causes. The method is suitable for rapidly selecting optimal AP connection through user devices under the WiFi environment.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for controlling AP connection priority in a WiFi environment. Background technique [0002] As we all know, WiFi, as the wireless communication method with the highest utilization rate at present, is closely related to people's life. However, the working frequency band of WiFi is strictly limited, which is divided into two categories: 2.4G and 5G. 2.4G has 13 channels in total, and only channels 1, 6, and 11 are independent of each other. Because 5G channels involve special purposes such as military affairs, other The channel also has its strict limitations, so more and more routers work within the limited channel bandwidth, and the actual communication capability will inevitably be reduced to varying degrees due to various environmental interference factors. [0003] The general way to control AP connection priority in traditional technology is: WiFi scans the AP ...

AI Technical Summary

Problems solved by technology

[0004] The above method is suitable under general conditions, but for specific working conditions of a certain AP, such as: whether the working channel of the AP is currently congested, whether the device nodes connected to the lower level of the current AP are saturated, and other specific issues cannot be detected in real time and provide corresponding solutions. connection selection

It can be seen that there are still defects in the way of controlling the priority of AP connection in the traditional technology.
