Wireless channel switching method and system, access point and workstation

Abstract

The embodiment of the invention provides a wireless channel switching method and system, an access point and a workstation, and the method is applied to the access point and comprises the steps: detecting whether a current wireless channel of current communication is interfered or not; if so, determining a target channel based on the interference intensity of each wireless channel determined by channel scanning in a preset scanning time period; broadcasting the identifier of the target channel and the switching moment to notify a workstation to switch from the current wireless channel to the target channel for communication based on the switching moment; and enabling the access point to switch to the target channel for communication based on the switching moment. The access point determines the interference intensity of each wireless channel through channel scanning in the preset scanning time period; after the target channel is determined, the identifier and the switching moment of the target channel are broadcasted, so that the access point and the workstation can be switched to the target channel for communication based on the switching moment, and the problems of data loss andcommunication interruption cannot be caused.

Description

technical field [0001] The present invention relates to the technical field of electronic communication, in particular to a wireless channel switching method, system, access point and workstation. Background technique [0002] Devices participating in wireless communication in a wireless communication network are divided into two types: access points and workstations. An access point can communicate with one or more workstations on a certain channel to form a network. Before the access point communicates with the workstation, it will select a channel among the multiple available wireless channels and fix it to communicate on this channel. The access point will periodically broadcast on this channel to announce the existence of the network. After the workstation is powered on, it monitors multiple wireless channels, and applies to join the network when it finds the broadcast of the access point on a certain channel. The access point will authenticate it. After the authentic...

AI Technical Summary

Problems solved by technology

Because the workstation finds that it cannot listen to the broadcast of the access point and searches for the access point to switch channels, the workstation will still send data to the access point on the original channel, and the access point cannot receive the data sent by the workstation. cause data loss, communication interruption
