PCT No. PCT/JP97/03302 Sec. 371 Date May 12, 1998 Sec. 102(e) Date May 12, 1998 PCT Filed Sep. 18, 1997 PCT Pub. No. WO98/12894 PCT Pub. Date Mar. 26, 1998When a power supply to a mobile station is turned on, mobile station identification information is read out from a non-volatile storage of a subscriber information module. A module identification information is read out from the non-volatile storage of the mobile station. The mobile station identification information which is read out is collated against the own mobile station identification information, and module identification information which is read out is collated against identification information for the loaded subscriber information module. If the module identification information does not coincide, the communication processing information is read out from the loaded subscriber information module and is stored into the non-volatile storage of the mobile station to update its content. Identification information for subscriber information module is stored into the non-volatile storage of the mobile station to update it. Identification information for the mobile station is stored into the non-volatile storage of the subscriber information module to update it. Subsequently, communication processing information stored in the non-volatile storage of the mobile station is read out to set up a condition which enables a communication. When the collation indicates a "coincidence", communication processing information which is previously stored in the non-volatile storage of the mobile station is read out to set up a condition which enables a communication.
