RADIO COMMUNICATION TERMINAL, TRANSMISSION FUNCTION ADJUSTING METHOD AND TRANSMISSION FUNCTION CONTROL PROGRAM USED IN THE RADIO COMMUNICATION TERMINAL,

摘要

Provided is a radio communication terminal capable of reducing a load on a mobile communication network and saving an uplink radio resource. In step A1, a separate channel setup request message requesting is transmitted from a mobile telephone (10) to a mobile communication network (NW). In step A2, it is judged whether rrc Connection Setup Complete (separate channel setup complete message) has been retransmitted upon separate channel setup during the previous communication. If Yes, control is passed to step A3. In step A3, a predetermined delay time T1 is added to the transmission timing by the separate channel and transmission of the separate channel (DPDCH) is started at the timing of the parameter [PC Preamble + SRB delay] + delay time T1. After this, no separate channel setup complete message will be retransmitted.
