Uplink data transmission and reception method and apparatus in a hand-off region using a transmission channel for the uplink service

The present invention is a code division in the use of the enhanced uplink channel (E-DCH) of a terminal in a mobile communication system using a multiple access system, associated to a cell that does not support cell and the E-DCH supporting the E-DCH hand the user terminal (UE) located in the overhead area is adapted to be mapped to the radio bearer comprises a radio bearer and a DCH does not include the E-DCH under control of the serving radio network controller (RNC), to one uplink logical channel, and as it moves between cells through any one radio bearer selected by the user terminal (UE) or the SRNC transmits the uplink data. The present invention reduces the delay time caused by the reconfiguration of the radio bearer to reduce the signaling overhead for the radio bearer reconfiguration.
