FIELD: means of communication. ^ SUBSTANCE: invention refers to communication method. In the mobile telephone terminal of the transmitting side there subsequently entered is voice data to be transmitted, and the determination whether the entered voice data is quiet is performed. The voice data accepted to be quiet is replaced with group numbers, and voice data indicating a loud voice, as well as group numbers being the result of the replacement, are transmitted in a wireless manner. On the other hand, in the mobile telephone terminal of the receiving side, the signals transmitted in a wireless manner are received, and voice data and group numbers of the received signals are different. Voice data is reproduced as it is, and group numbers are reproduced as silence, and the processing is performed on the basis of group numbers as well. This allows transmitting the pre-determined data once more with high efficiency and without considerable deterioration of communication quality. This also simplifies the following-up participation in the group call. ^ EFFECT: providing effective transmission of voice information and control information without reducing transmission efficiency of voice information. ^ 6 cl, 7 dwg |
