A mobile terminal includes a predetermined modulating and demodulating code generator, and makes a call connection request through an access channel based on broadcast information from a base station. The call connection request contains an equipment number of the mobile terminal, and based on this equipment number, the network side device discriminates a code corresponding to this mobile terminal. The base station modulates and demodulates a reverse channel and forward channel signals based on the discriminated code.
