With reference to the first aspect, in an implementation of the first aspect, the cancellation condition includes a fifth signal quality threshold, and when the signal quality of the serving cell is greater than the fifth signal quality threshold, the handover cancellation condition is satisfied; or the cancellation condition includes a sixth signal quality threshold, and when the signal quality of the candidate target cell is less than a sum of the sixth signal quality threshold and the signal quality of the serving cell, the handover cancellation condition is satisfied.
In this embodiment of this application, when the signal quality of the serving cell becomes better, because the signal quality of the serving cell is relatively good, normal running of services can also be ensured with no need to perform the handover. Therefore, in this embodiment of this application, when the signal quality of the serving cell is relatively good, the process of determining the target cell that satisfies the trigger condition is canceled, to avoid an unnecessary determining process, reduce energy consumption of the terminal device, and reduce implementation complexity of the terminal device.
With reference to the first aspect, in an implementation of the first aspect, that the terminal device cancels the determining process, and continues to communicate with the serving cell includes the following.
The terminal device sends a notification message to the first network device, where the notification message is used to indicate the first network device to release the configuration information.
