Abstract: PURPOSE: A method and an apparatus for transmitting user data in an HSDPA(High Speed Downlink Packet Access) mobile communication system are provided to efficiently use lub transmission resources and use buffer resources of nodes B which manage cells of an active set by transmitting a data frame of a frame protocol to only node B which manages best cells. CONSTITUTION: If a transmitting data frame exists, an SRNC(Serving Radio Network Controller) transmits an FP(Frame Protocol)(1501). The SRNC checks whether an MR(Measurement Report) including channel state information with nodes B is received from a UE(User Equipment)(1502). If the MR is received, the SRNC judges whether a new radio link is set up(1503). If it is determined that the new radio link is set up, the SRNC transmits a radio link setup request to nodes B which belong in an active set(1504). The SRNC checks whether a radio link setup response about the radio link setup request is received(1505). If the radio link setup response is received, the SRNC sets an lub channel using an ALCAP(1506). An SRNC adds identifiers of nodes B in which the channel is newly set up to an ASB(Active Set Node B)(1507). If the MR is not received, the SRNC checks whether a BCSI(Best Cell Switching Indication) is received from the node B(1508). If the BCSI is received from the node B, the SRNC checks whether the node B is identical to a node B stored in a BNB(Best cell Node B)(1509). If the BNB is changed, the SRNC updates the BNB(1510) and switches the channel to a new BNB(1511).
