摘要： PURPOSE:To decrease the number of connecting functions necessary for call connection and to reduce logical hardwares by recognizing a local connection call and an incoming transfer connection call as an outgoing connection call and an incoming connection call respectively and executing the call connection by combining the outgoing connecting function and the incoming connecting function. CONSTITUTION:The respective call connections such as outgoing connection call, incoming connection call, local connection call and incoming transfer connection call in a mobile communication are realized by combining two functions such as the outgoing connecting function and the incoming connecting function. Namely, mobile terminals 1 and 2 are connected with radio base stations 7 and 8, which is connected with a speech path device 11. And a mobile communication exchange 16 is constituted in order to include the speech path device 11, a central processing device 12, a state storage memory 13 and information transfer memories 14 and 15 and the speech path device 11 is connected with fixed terminals 23 and 24 via trunk line exchanges 19 and 20 and through subscriber-line exchanges 21 and 22. Radio zones 3 and 4 are included in the control area 25 of the mobile communication exchange 16 and a folded communication line 26 is connected to the speech path device 11.

摘要： 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.
