1. A method of data forwarding during handover in a mobile communication system, the method comprising: selecting first and second base stations from a plurality of other base stations as candidate base stations for a handover of a user equipment by a source base station, the source base station and the plurality of other base stations forming a mobile communication system and coupled to a gateway, wherein a telecommunication link is established between the user equipment and the gateway through the source base station; selecting the first target base station from said candidate base stations for an attempted handover of the user equipment by said source base station; obtaining downlink data from the gateway and uplink data from the user equipment by said source base station; forwarding said uplink and downlink data from said source base station to said first target base station; receiving an arrival message from the second target base station of the candidate base stations indicative of access of the user equipment to the second target base station after the second target base station accepted an access request from the user equipment in response to receiving a connection establishment message from the user equipment after the user equipment detected a handover failure or a radio link failure in conjunction with the attempted handover to the first target base station; and forwarding said uplink and downlink data to said second target base station.
