440. The first network device sends conditional handover configuration information to the terminal device.
For example, the conditional handover configuration information may be sent by using an RRC message. It should be understood that the message may be a new RRC message, an RRC reconfiguration message including a ReconfigurationWithSync information element, or an RRC connection reconfiguration message including a mobility control information (mobility control info) information element. This embodiment of this application is not limited thereto.
The conditional handover configuration information is used to configure a first measurement object and a handover condition threshold. The first measurement object configured by using the configuration information may be the same as or different from the measurement object configured by using the measurement configuration information in step 410.
Specifically, the configuration information includes the first measurement object and the handover condition threshold.
Optionally, the 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 type (for example, A1 to A6) associated with the handover condition threshold, a hysteresis value, a time to trigger TTT, and a reference signal type.
