A mobile communication system and its method, which uses a discrimination code specific to a mobile terminal as an discriminating signal for both of reverse channel and forward channel between a mobile terminal and a mobile communication network, are provided. 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.

1. A mobile communication system comprising:a mobile communication network; and a mobile terminal device which performs communications with said mobile communication network, said mobile communication network including a plurality of base stations and a base station control equipment by a code division multiple access (CDMA) system, wherein said mobile terminal comprises: a call connection requesting part for transmitting, through a predetermined control channel, a call connection request signal by adding specific information provided for said mobile terminal; a transmitting part for diffusing and modulating a transmitting signal of a reverse channel transmitted from said mobile terminal to each of said base stations based on a transmission diffusing code specified by said specific information provided for said mobile terminal; and a receiving part for oppositely-diffusing and demodulating a received signal of a forward channel transmitted from each of said base stations to said mobile terminal based on a receiving oppositely-diffusing code specified by said specific information provided for said mobile terminal; and wherein said mobile communication network further comprises: a translating part for translating said specific information provided for said mobile terminal, which is contained in said call connection request signal received through said control channel, and extracting a diffusing code used for each of said reverse channel and forward channel for said mobile terminal; a transmitting part for diffusing and modulating a transmitted signal based on said forward channel transmission diffusing code extracted by said translating part; and a receiving part for oppositely-diffusing and demodulating a received signal based on said reverse channel receiving oppositely-diffusing code extracted by said translating part.
