For another example, an event type of a reporting event configured in the reporting configuration is an event A5, and corresponding thresholds are a second reporting condition threshold (for example, a first threshold (threshold 1)) and a third reporting condition threshold (for example, a second threshold (threshold 2)). If a trigger condition of the event A5 is satisfied, it indicates that signal quality of the neighboring cell is greater than the threshold 2 and signal quality of the serving cell is less than the threshold 1. To be specific, when the signal quality of the neighboring cell corresponding to the measurement object is greater than the threshold 2, and the signal quality of the serving cell corresponding to the measurement object is less than the threshold 1, the terminal device sends the measurement report to the first network device.
