PURPOSE:To attain complete message transmission by transmitting always the state of a mobile station equipment to a base station equipment to allow the base station equipment to grasp always the state of the mobile station equipment and switching the character transmission into the voice transmission depending on the state of the mobile station equipment. CONSTITUTION:A command or the like from the base station equipment A of a communication equipment is inputted from a keyboard 19, monitored on a display 21 and transmitted to a mobile station equipment B via a radio equipment 23 and an antenna 9 under the control of a control section 20. An antenna 5 and a radio equipment 4 of the equipment B receive a signal from the equipment A and gives the signal to a control section 3 from a MODEM2. A reception signal is displayed on a display device 10 via a changeover switch 14 and outputted to a printer 11. Further, the information collected by an information collecting device 1 is transmitted to the equipment A conversely via the switch 14, the MODEM2, the radio equipment 4 and the antenna 5. Then the equipment A always grasps the stage of the equipment B and changes over the character transmission into the voice transmission which using microphones 15, 17 and speakers 16, 18 depending on the state of the equipment B. |
