A method used for handoff comprises the following steps: adopting the measuring value of the signal quality of the current community to predict the value of the signal quality in the future specified time to obtain the first predicted value; starting timing when the first predicted value is lower than the first threshold; and sending the measuring report if the first predicted values are all lower than the first threshold in the first time period. The predicted value of the signal quality is adopted to replace the original measuring value, so the event trigger time point is advanced, thus saving precious time for subsequent handoff and further ensuring that UE can still successfully carry out handoff under the condition of rapid deterioration of link. The invention also discloses a device used for handoff.
