PURPOSE:To prevent the wrong use by giving two peculiar numbers, namely, a dial number and a terminal number to a mobile terminal and collating these numbers to identify whether a call is correct or not when call originating and terminating are controlled. CONSTITUTION:When receiving a subscriber number D of a mobile terminal 1, which is found distinctly on a telephone directory or the like, from the fixed network side, a mobile communication exchange 5 identifies a home memory station 7, where the device number of the mobile terminal 1 is stored, in accordance with the subscriber number D and transmits the subscriber number D through a common line signal path 6. The home memory station 7 reads out a device number X corresponding to the subscriber number D of the mobile terminal 1 and returns the subscriber number D and the device number X to the mobile communication exchange 5 through the common line signal path 6. When the mobile communication exchange 5 transmits the received device number X through a control line 4, a radio base station 3, and a radio channel 2, the regular mobile terminal 1 receives the device number X and transmits a subscriber number ID stored in the mobile terminal 1 to the exchange 5 through the radio channel 2, the radio base station 3, and the control line 4. The exchange 5 checks whether the subscriber number D and the subscriber number ID coincide with each other or not. |
