A circuit switched fallback, CSFB, handover method, wherein the method comprises: receiving (101, 201), by a base station serving a Long Term Evolution, LTE cell, a CSFB indication, wherein the CSFB indication indicates that user equipment is handed over from the LTE cell to a 2G/3G cell to perform a circuit switched, CS, service, and the site of the base station serving the LTE cell is the same as a site of a base station serving the 2G/3G cell; sending, by the base station after receiving the CSFB indication, a measurement control message to the user equipment, wherein the measurement control message is used to instruct the user equipment to measure cell signal quality and send a corresponding event measurement report; and according to a receiving status of the event measurement report sent by the user equipment, selecting, by the base station, to complete CSFB handover by using blind handover, or to complete CSFB handover by using measurement-based handover; wherein the sending a measurement control message to the user equipment comprises: sending a first measurement control message comprising a first threshold and a second measurement control message comprising a second threshold to the user equipment simultaneously, wherein the first measurement control message is used to instruct the user equipment to measure signal quality of a current LTE cell and send a first event measurement report if the measured signal quality of the LTE cell is greater than the first threshold, and the second measurement control message is used to instruct the user equipment to measure signal quality of the current LTE cell and a 2G/3G neighboring cell of the current LTE cell and send a second event measurement report if the measured signal quality of the 2G/3G neighboring cell is greater than the second threshold; and accordingly, the according to a receiving status of the event measurement report sent by the user equipment, selecting, by the base station, to complete CSFB handover by using blind handover, or to complete CSFB handover by using measurement-based handover comprises: if the first event measurement report is first received, selecting to complete the CSFB handover by using the blind handover; and if the second event measurement report is first received, selecting to complete the CSFB handover by using the measurement-based handover. receiving (101, 201), by a base station serving a Long Term Evolution, LTE cell, a CSFB indication, wherein the CSFB indication indicates that user equipment is handed over from the LTE cell to a 2G/3G cell to perform a circuit switched, CS, service, and the site of the base station serving the LTE cell is the same as a site of a base station serving the 2G/3G cell;
