A channel switching method, applied at a mobile terminal side and comprising: sending (S101), by a mobile terminal, 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, wherein the channel switching command comprises at least a set rate threshold; and receiving (S102), by the mobile terminal, a feedback message from the first access point, wherein the feedback message is sent by the second access point to the first access point; and when the feedback message indicates that channel switching preparation of the second access point is ready, breaking, by the mobile terminal, a connection to the first access point and setting up a connection to the second access point to complete the channel switching; wherein the channel switching command further comprises a frequency scan interval; and the second access point performs channel scan and switching processing according to the set rate threshold and the frequency scan interval, and wherein the method further comprises, when the feedback message indicates that a channel with a rate that is higher than the set rate threshold is not found after the second access point performs channel scan, sending, by the mobile terminal, a frequency scan interval adjustment command to the first access point, so that the first access point sends the frequency scan interval adjustment command to the second access point and the second access point performing channel scan and switching processing according to an updated frequency scan interval. sending (S101), by a mobile terminal, 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, wherein the channel switching command comprises at least a set rate threshold; and receiving (S102), by the mobile terminal, a feedback message from the first access point, wherein the feedback message is sent by the second access point to the first access point; and when the feedback message indicates that channel switching preparation of the second access point is ready, breaking, by the mobile terminal, a connection to the first access point and setting up a connection to the second access point to complete the channel switching; wherein the channel switching command further comprises a frequency scan interval; and the second access point performs channel scan and switching processing according to the set rate threshold and the frequency scan interval, and wherein the method further comprises, when the feedback message indicates that a channel with a rate that is higher than the set rate threshold is not found after the second access point performs channel scan, sending, by the mobile terminal, a frequency scan interval adjustment command to the first access point, so that the first access point sends the frequency scan interval adjustment command to the second access point and the second access point performing channel scan and switching processing according to an updated frequency scan interval. <EOS>
