To provide a wireless communication terminal enabling to reduce the load on a mobile communication network and saving upstream wireless resources.In step A1, an establishment request message for an individual channel is transmitted from a cell phone 10 to a mobile communication network NW. In step A2, determination is made as to whether an rrc Connection Setup Complete (individual channel establishment completion message) has been retransmitted at the establishment of the individual channel at the time of the previous communication. When the retransmission has been done (YES), it proceeds to step A3. In step A3, a predetermined delay time T1 is added to transmission timing with the individual channel, and transmission begins along the individual channel (DPDCH) at timing of parameters [PC Preamble+SRB delay]+delay time T1. As a result, after that, an individual channel establishment completion message will not be retransmitted.
