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)

In this embodiment of this application, the terminal device may be handed over from the serving cell (that is, the source cell) to the target cell when the handover trigger condition is satisfied. In an actual application, there may be a case in which the handover trigger condition is never satisfied or a conditional handover procedure does not need to be performed. This embodiment provides the method for canceling a conditional handover. When a condition for triggering cancellation of a conditional handover is satisfied, the information included in the conditional handover configuration information is deleted, and a reserved resource is released, so that storage overheads and a waste of resources can be reduced.

It should be understood that FIG. 7 describes only a method for canceling a conditional handover procedure in a process of searching for a target cell. In an actual application, the conditional handover procedure may also be canceled in a random access process. This embodiment of this application is not limited thereto. For example, in a process in which the terminal device performs the random access to the first target cell, if the handover cancellation condition is satisfied, the terminal device cancels the random access process, and continues to communicate with the serving cell.
