A channel switching method, apparatus, and system are disclosed. A mobile terminal sends a channel switching command to a first access point, so that the first access point parses the channel switching command and sends a parsed channel switching command to a second access point and the second access point performs channel switching according to the parsed channel switching command. The mobile terminal receives a feedback message from the first access point. When the feedback message indicates that channel switching preparation of the second access point is ready, the mobile terminal breaks a connection to the first access point and sets up a connection to the second access point to complete the channel switching.
