PROBLEM TO BE SOLVED: To provide a radio communication device which needs to discriminate a communication kind in one communication network. SOLUTION: The radio communication device has communication kinds such as a duplex, a half-duplex, and a broadcast communication mode, and outputs a sound of different tone quality by adding an identification code 4 indicating a communication kind in a radio control signal for a mutual communication connection between transmission and reception devices 1 and 8 and sending them out of a transmission terminal device 1, displaying the contents of the communication kind in the radio control signal in characters at a character display part 11 through the processing of an identification code reception part 9 and a reception processing part 10 when a line connection is made by a reception terminal device 8 through a radio repeater 5, and varying the generation frequency of a tone generation part 12 in the reception terminal device 18 and its combination and repetition cycle. Further, a speech is outputted a variable sound volume output part 13 while the reception sound volume of a receiver is varied by an incoming terminal device 8 according to the contents of the communication kind so that a termination operator can hear it with the reception sound volume matching the communication kind at the time of termination. |
