ABSTRACT:
In a radio telephone system and a call charging method used in the radio telephone system, when a user of a radio telephone issues a telephone call to a public telephone network by utilizing a radio controller installed in a PBX employed on the premises of a company to which the telephone user does not belong, the PBX reports both terminal number information of the radio telephone and call account information for charging the call account to the terminal to the public telephone network. When the information is received, the public telephone network charges the call account to the radio telephone. If the information is not transmitted from the PBX to the public telephone network, the call account is charged to the call originating line of the PBX.
