Abstract

PURPOSE:To facilitate the connection from the exchange to the mobile radio terminal by receiving the area signal from the base station within each area through the mobile terminal and then transmitting the signal including the self-terminal number every time the terminal changes its belonging area. CONSTITUTION:Base station 4 and 5 of area A and B transmit the area identification signal every fixed time, and mobile radio terminal 6 receives the area identification signal from the base station in the area of its own. When terminal 6 moves to area A from other area, it detects the variation of the area identification signal to be received to transmit the signal including the self-terminal number to station 4. Station 4 transmits the signal to exchange 1 via circuit 7, and exchange 1 memorizes the storage position information of circuit 7 of the memory corresponding to the terminal. When the incoming call is produced at terminal 6, exchange 1 calls out nearest telephone 2 of terminal 6 based on the contents of the memory to secure the talking with the owner of terminal 6.
