PURPOSE:To increase the frequency efficiency and then realizing the large capacity as well as the economization, by carrying out the message transmission between the mobile station and the fixed terminal which is added to the telephone of the subscriber to be connected to the mobile message exchange. CONSTITUTION:The communication system comprises fixed terminal 7, telephone 8, general exchange 9, mobile message exchange 10, mobile message control station 11, mobile message base station 13, mobile station 15 and others. Thus in case the message is transmitted to station 15 from terminal 7, fixed calling subscriber supplies the message to the keyboard of terminal 7 and then dials the number corresponding to the mobile message communication service. Thus terminal 7 is connected to station 11. Then station 11 gives the order to station 13 to call station 15 and at the same time sets up the radio circuit. After this, the message is transmitted to station 15 (with transmission velocity of several kb/s). |
