Abstract: When triggering a handover request, a source network device requests a measurement indication from a target access network device using the handover request, where the measurement indication indicates the terminal device to measure a channel state of a target cell. In this way, the source network device sends the measurement indication to the terminal device using an RRC reconfiguration message. Then, the terminal device measures the specified channel state of the target cell based on the measurement indication, to obtain a measurement result, and then determines, depending on whether the measurement result meets a handover condition, whether to perform cell handover.
