摘要： A method apparatus and system for cell handover are provided. The method includes the following steps. User equipment (UE) initiates a cell handover. If the UE is not in a downlink discontinuous reception state, the cell handover is performed when the UE is not in the downlink discontinuous reception state. If the UE is in a downlink discontinuous reception state, the UE exits the downlink discontinuous reception state and performs the cell handover when the UE is not in the downlink discontinuous reception state. The embodiments of the present invention prevent the problem that the UE cannot receive a handover indication command during the cell handover in time because the UE is in the downlink discontinuous reception state, thus reducing time delay of the cell handover, avoiding longer service interruption, and reducing the call drop rate.
