A method for reporting a measurement report of a measurement event, comprising: determining that a measurement event is generated at a time t0 in a user equipment UE in an activated state of discontinuous reception DRX mode; judging whether the time from t0 to a time point t1 at which the UE enters a DRX sleep state this time is less than the duration of a first time to trigger, TTT1, which is configured to the measurement event by the network, and whether the time from t0 to the time point t2 at which the UE exits a DRX sleep state for the last time is larger than the duration of TTT1; using TTT1 to time the measurement event, when it is judged that t1-t0 is greater than or equal to the duration of TTT1, and t2-t0 is less than or equal to the duration of TTT1; using a second time to trigger, TTT2, to time the measurement event, when it is judged that t1-t0 is less than the duration of TTT1, and t2-t0 is larger than the duration of TTT1, forcing the UE to perform a measurement operation to a serving cell and at least one neighboring cell of the serving cell when being in next one or next several activated states of DRX mode after the generation of the measurement event, and obtaining a measurement result; judging whether the measurement event corresponding to TTT1 is not outdated according to the measurement result by comparing the measurement event corresponding to TTT1 to the measurement result; when the measurement event corresponding to TTT1 is not outdated, reporting the measurement report corresponding to the measurement event corresponding to TTT1 to a network; otherwise, not reporting the measurement report corresponding to the measurement event corresponding to TTT1 to the network or updating the measurement event. determining that a measurement event is generated at a time t0 in a user equipment UE in an activated state of discontinuous reception DRX mode; judging whether the time from t0 to a time point t1 at which the UE enters a DRX sleep state this time is less than the duration of a first time to trigger, TTT1, which is configured to the measurement event by the network, and whether the time from t0 to the time point t2 at which the UE exits a DRX sleep state for the last time is larger than the duration of TTT1; using TTT1 to time the measurement event, when it is judged that t1-t0 is greater than or equal to the duration of TTT1, and t2-t0 is less than or equal to the duration of TTT1; using a second time to trigger, TTT2, to time the measurement event, when it is judged that t1-t0 is less than the duration of TTT1, and t2-t0 is larger than the duration of TTT1, forcing the UE to perform a measurement operation to a serving cell and at least one neighboring cell of the serving cell when being in next one or next several activated states of DRX mode after the generation of the measurement event, and obtaining a measurement result; judging whether the measurement event corresponding to TTT1 is not outdated according to the measurement result by comparing the measurement event corresponding to TTT1 to the measurement result; when the measurement event corresponding to TTT1 is not outdated, reporting the measurement report corresponding to the measurement event corresponding to TTT1 to a network; otherwise, not reporting the measurement report corresponding to the measurement event corresponding to TTT1 to the network or updating the measurement event.
