Method and apparatus for uplink data transmission in handover area using transport channels for uplink service

摘要

A method and an apparatus for uplink data transmission using an enhanced uplink dedicated channel (E-DCH) in a mobile telecommunication system which employs a code division multiple access (CDMA) scheme are provided. User equipment (UE) located in a handover area related to a cell supporting the E-DCH and a cell not supporting the E-DCH configures a radio bearer including the E-DCH and a radio bearer including an uplink dedicated channel (DCH) such that they are mapped to one uplink logical channel, and transmits uplink data through any one radio bearer selected by the UE or a serving radio network controller (SRNC). Thus, a delay time due to radio bearer reconfigurations and signaling overhead for the radio bearer reconfigurations are reduced.
