US 2010/0165850 A1 · DATA FORWARDING METHOD AND APPARATUS THEREOF

Abstract

The invention relates to a method of data forwarding during handover in a mobile communication system, the mobile communication system comprising a plurality of base stations and a base station, the base station being coupled to a gateway, a telecommunication link being established between a user equipment and the base station, the method comprising: selecting a set of base station from the plurality of base stations as candidate base stations for a handover of the user equipment by the base station; selecting a first target base station for handover from the set of base stations by the base station; obtaining downlink data from a gateway and up-link data from a user equipment by the base station; forwarding the uplink and downlink data from the base station to the first target base station. The method further comprises: detecting a handover or radio link failure by the user equipment;—transmitting a connection establishment message to a second target base station of the set of base stations by the user equipment; accepting access request of the user equipment by the second target base station; transmitting a message by the second target base station to the base station, the message being indicative of access of the user equipment to the second target base station; and forwarding the uplink and downlink data to the second target base station.
