A method used for handoff comprises the following steps: obtaining the signal quality of the current community; starting timing when the signal quality of the current community is lower than the first threshold; setting the timing length according to the variation of the signal quality; and sending the measuring report if the signal quality of the current community is lower than the first threshold all the time in the timing length, wherein the faster the signal quality varies, the shorter the timing length is. Fast signal attenuation is coped with by adjusting the timing threshold of a timer, namely in the switching zone, the received attenuation velocity of the signal quality of the current community is different under the conditions of fast movement and slow movement of UE. UE can be ensured to timely switch to the new base station in any state by correspondingly setting the timing threshold of the timer according to the variation velocity of the signal quality linking UE and the original base station. The invention also discloses a device used for handoff.
