摘要

This application provides a communication method and a communications apparatus. The method includes: receiving, by a terminal device, conditional handover configuration information from a first network device, where the first network device is a network device to which a serving cell belongs, and the serving cell is a cell that currently accessed by the terminal belongs; and determining, by the terminal device, a first target cell based on the conditional handover configuration information.

說明書

Optionally, the configuration information may further include TTT indication information, and the TTT indication information is used to indicate whether the terminal device uses a TTT mechanism to search for the first target cell.

If the TTT indication information indicates that the TN mechanism does not need to be used, once the terminal device determines that the trigger condition is satisfied, the terminal device is handed over to the target cell that satisfies the trigger condition. If the TTT indication information indicates that the TN mechanism needs to be used, and the candidate target cell always satisfies the trigger condition only when within a time to trigger (TTT) configured by a network, the terminal device determines the candidate target cell as the first target cell. After the time to trigger is reached, the terminal device is handed over to the first target cell that satisfies the trigger condition.

It should be understood that a length of the time to trigger corresponding to the TTT mechanism may be configured in the reporting configuration, or may be configured in the conditional handover configuration information. This embodiment of this application is not limited thereto.
