1. A handover method, comprising:
receiving, by a user equipment (UE), a radio resource control (RRC) reconfiguration message from a source base station, wherein the RRC reconfiguration message comprises a list of target cells for performing a conditional handover by the UE, and information of each target cell in the list of target cells for performing the conditional handover comprises: a conditional handover command of the target cell generated by the target cell, and a first measurement configuration identifier, wherein the first measurement configuration identifier is used to indicate a first execution condition for the UE to perform a conditional handover to the target cell; and
selecting, by the UE, responsive to detecting that a radio link failure has occurred with a source cell, a target cell from the list of target cells; and
initiating, based on the selecting, a handover to the target cell.
