Claim:
1. A method for a mobile terminal to switch from a source base station to a target base station, comprising: acquiring designated channel resource information from channel resources used by a source base station, wherein the designated channel resource information is used for the source base station to transmit a switching command to the mobile terminal; calculating a signal to interference and noise ratio of a designated channel resource; determining whether the signal to interference and noise ratio is smaller than a preset signal to interference and noise ratio; when the signal to interference and noise ratio is smaller than the preset signal to interference and noise ratio, acquiring information of a relevant base station, which uses the designated channel resource, wherein the relevant base station is neither the source base station nor the target base station; sending indication signaling to the relevant base station according to the information of the relevant base station, wherein the indication signaling carries the designated channel resource information, the indication signaling is used to instruct the relevant base station to stop using the designated channel resource when the mobile terminal switches to the target base station, and the indication signaling is one of the following: load information indication, a resource state request, and radio resource state information correction; sending a switching request message to the target base station, wherein the switching request message comprises the designated channel resource information, and the switching request message is further used to instruct the target base station to stop using the designated channel resource when the mobile terminal performs switching; and sending the switching command to the mobile terminal through the designated channel resource.
