The present invention discloses a radio connection re-establishment method, including: starting a first timer if a first preset number of out-of-synchronization indications are obtained continuously, where the first preset number and/or a duration of the first timer corresponds to a cell of highest signal quality measured by a user equipment UE; and triggering a radio resource control RRC re-establishment procedure if a second preset number of synchronization indications are not received before timeout of the first timer. The radio connection re-establishment method in the present invention reduces overhead.
