摘要：
A switching system (3) has, in addition to an ordinary accounting function, an origination-only accounting control unit 6 to monitor the number of message units used by an origination-only portable telephone (1B) identified by a terminal identification number and to deny the origination of a call by the origination-only portable telephone (1B) upon the increase of the number of used message units to a predetermined number. The origination-only accounting control unit (6) accepts the origination of a call made by the origination-only portable telephone (1B) when a prescribed input about the origination-only portable telephone (1B) is given thereto by a system operator by operating a predetermined terminal device (7) or the like after the denial of origination of a call by the origination-only portable telephone (1B).
