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(shuō)明書(shū)

Specifically, in this embodiment of this application, when the signal quality of the serving cell deteriorates, the terminal device may determine the target cell based on the conditional handover configuration information sent by the first network device. Compared with the current technology in which when signal quality of a current serving cell deteriorates, a network device sends a handover message to indicate, to a terminal device, a target cell to which the terminal device needs to be handed over, this embodiment of this application can ensure a success rate of sending the configuration information when the first network device sends the configuration information to the terminal device, for example, the first network device sends the conditional handover configuration information to the terminal device when link communication quality is relatively good. Further, the terminal device determines the target cell based on the configuration information, and performs random access to the determined target cell, to complete a handover procedure, thereby improving a handover success rate.

With reference to the first aspect, in an implementation of the first aspect, the conditional handover configuration information is used to configure a first measurement object and a handover condition threshold, where a measurement result of the first measurement object and the handover condition threshold are used to determine whether a trigger condition of a conditional handover is satisfied.

That the terminal device determines a first target cell based on the conditional handover configuration information includes the following.
