COMMUNICATION METHOD COMMONLY USING MOBILE COMMUNICATION TERMINAL AND COMMUNICATION SYSTEM CONTROLLER USED THEREFOR

摘要

Upon receiving an identification signal from an indoor base station (30), a mobile terminal (10) makes a location registration request to a controller (20) through the station (30). When the number and incoming address of the terminal (10) are stored, the controller (20) sends the acceptance of location registration to the terminal (10); when the number and address are not stored, the controller (20) stores the location of the terminal (10), the number and the incoming address, and makes a location registration request to a mobile communication exchange (40). The exchange (40) registers the location of the terminal (10) as location registration information in the area for the terminal (10) in a location register (50). Thereafter, when a request of location registration of the terminal (10) is made to the register (50), the register (50) requests the controller (20) to eliminate the incoming address added through the exchange (40).
