1. A method comprising:
sending, by an apparatus, a measurement report to a source access network device, wherein the measurement report comprises a second signal quality of a target cell obtained through measurement performed by the apparatus on the target cell, and further comprises a first indication indicating that the target cell is suspicious;
receiving, by the apparatus, a radio resource control (RRC) reconfiguration message from the source access network device, wherein the RRC reconfiguration message carries a measurement indication and a handover condition, the measurement indication indicating the apparatus to measure a channel state of the target cell;
measuring, by the apparatus, the channel state of the target cell based on the measurement indication, to obtain a first signal quality of the target cell; and
determining, by the apparatus based on the first signal quality of the target cell and the handover condition, whether to perform a handover procedure to handover to the target cell.
