PURPOSE: To enable connection to the base station of a system even when the system ID of that system is not matched. CONSTITUTION: With the position registration of a mobile station 5, any zone number is not used but the system ID of exchanges 1 and 2 and the base station ID of base stations 3 and 4 are used and the common number of the system is allocated to the zone number in alarm information transmitted by the base stations 3 and 4. Thus, even when the system ID is not matched but the system common numbers provided for the base stations 3 and 4 and the mobile station 5 are matched, the base stations 3 and 4 and the mobile station 5 can be connected. Thus, it is not necessary for the mobile station 5, which moves through plural zones, to register the position again or to previously store a lot of system ID each time it moves through the zones. |
