PURPOSE:To decrease the possibility of cut off of head of speech by delaying the time from a point of time detecting a voice energy from a telephone set at the transmission side until a channel assignment request is received from a mobile exchange station to introduce the TASI system to the mobile telephone system. CONSTITUTION:When a voice input come from a telephone set 6, the voice energy is detected by a voice energy detecting circuit 8 and read by a control section 5. The control section 5 controls a synthesizer 4 by the detection of the voice energy and transmits the channel assignment request to a mobile exchange station. A voice delay circuit 7 delays the voice by the time length from the detection of the voice energy until the reception of the channel assignment command from the mobile exchange station. When the channel assignment signal is transmitted from the mobile exchange station, a reception section 2 transmits the information to the control section 5 and the synthesizer 4 generates a designated frequency. Thus, the transmission section 3 transmits a radio wave from an antenna 9 toward the mobile exchange station in the frequency of the synthesizer 4. |
