らに詳しく説明する。In the present invention, the base station and the terminal reproduce the stored voice data while storing the voice data in the memory during a normal call. During the silence period that occurs at the time of channel switching or handover, the audio data stored in the memory is continuously reproduced to reduce the silence time and reduce discomfort due to silence. Hereinafter, the present invention will be described in more detail with reference to the drawings and the like.

After the accumulation for a certain period of time without affecting the conversation is completed, the audio data stored in the FIFO memory 7 is sent to the audio processing unit 8 to reproduce the audio.

At this time, the voice data stored in the FIFO memory 7 is sent to the voice processing unit 8 to reproduce voice. . When the audio data stored in the FIFO memory 7 is exhausted, the audio output is muted.

Then, the storage of the audio data is started again. In the case of a sound, the audio data is immediately reproduced and output as in this example.

Thereafter, the audio data is sent to the audio processing unit 8 and the reproduction of the audio is resumed.

る。As described above, in the present invention, voice data is first stored in the FIFO memory 7 at the start of a call, and when the stored voice data reaches a certain amount of time that does not hinder the call, the voice data is sent to the voice processing unit 8. Send and play from the speaker. If audio data cannot be received due to handover or channel switching, the terminal continues to reproduce the audio data stored in the FIFO memory 7. This allows
The mute time due to handover or channel switching is shortened by the time stored in the FIFO memory 7, and the sense of incongruity due to audio interruption can be reduced. Further, when the handover or the channel switching is completed, the sound is output to the speaker without storing the sound in the FIFO memory 7 until the silence of the received sound is detected. When the silence detection unit 7 detects silence, the audio data is FI
The data is stored in the FO memory 7, and the data required for the conversation is stored in the FIFO memory 7 without erasing. FIFO
When the audio data for the predetermined time is again stored in the memory 7, the audio data is sent to the audio processing unit 8, and the reproduction of the audio is resumed.

である。As described above, according to the present invention, even when the call is interrupted due to a handover or the like, the interruption of the voice is minimized, and the call can be continued with a sense of discomfort to the caller reduced. Also, in this example, the example of reception from the base station to the terminal has been described, but the same applies to transmission from the terminal to the base station, and a simple configuration can improve the call quality.
