With reference to the second aspect, in an implementation of the second aspect, the conditional handover configuration information includes the first measurement object and the handover condition threshold.
With reference to the second aspect, in an implementation of the second aspect, the conditional handover configuration information further includes at least one of the following information: a measurement identifier associated with the first measurement object and the handover condition threshold, an event corresponding to the handover condition threshold, a hysteresis value, and a time to trigger TTT.
With reference to the second aspect, in an implementation of the second aspect, the conditional handover configuration information and the measurement configuration information are received by the terminal device by using one piece of signaling.
With reference to the second aspect, in an implementation of the second aspect, the conditional handover configuration information includes at least one of the following information: a cell identifier of the candidate target cell, frequency information of the candidate target cell, a C-RNTI allocated by the candidate target cell to the terminal device, an identifier of a first beam that belongs to the candidate target cell, and a first random access channel RACH resource.
