In other words, in this embodiment of this application, the terminal device may be triggered relatively early to send the measurement report. In other words, when the signal quality of the serving cell is relatively good, the terminal device may be triggered to send the measurement report.
It should be understood that in this embodiment of this application, after the trigger condition of the event in the reporting configuration associated with the measurement object is satisfied, the terminal device may send the measurement report once. Optionally, the terminal device may alternatively periodically send the measurement report. For example, after the terminal device determines that the trigger condition of the event in the reporting configuration associated with the measurement object is satisfied, the terminal device sends the measurement report, and the terminal device sends the measurement report again at an interval of a specific period of time. This embodiment of this application is not limited thereto. In an actual application, in step 320, the network device may receive a plurality of measurement reports from one terminal device within a period of time. This embodiment of this application is not limited thereto.
330. The first network device performs handover preparation with the candidate target network device.
