周期性间断发送的语音码流平滑传输方法及系统技术方案

本发明专利技术公开了一种周期性间断发送的语音码流平滑传输方法及系统，属于通信技术领域。在本发明专利技术的所述方法中，发送端接收语音帧，并通过超帧将语音帧的语音数据发送至接收端；所述超帧由多个子帧和位于超帧末尾的填充域组成，所述方法的特征在于：a)发送端缓存一个语音帧的数据包，并在收到下一个语音帧的数据包之后开始向接收端发送语音数据；b)发送端通过一个超帧中的子帧的剩余数据发送能力向接收端发送上一超帧遗留的待发送语音数据；c)在超帧的填充域的时间窗口内，发送端停止向接收端发送语音数据。本发明专利技术可用于卫星通信尤其是卫星移动通信系统。

Method and system for transmitting voice code stream by periodically interrupted transmission

The invention discloses a method and a system for transmitting a voice code stream intermittently transmitted intermittently, belonging to the field of communication technology. In the method of the invention, the sender receives the speech frame, and through the super frame transmitting speech data frames to the receiving end; the super frame is composed of a plurality of sub frames and is located in the super frame at the end of the filling domain, the method is characterized by: a) sending a speech frame buffer the data packets, and after the data packets received from the voice of the next frame to the receiver to send voice data; b) transmitting through the remaining data transmission capability of a super frame in the sub frame is transmitted to the receiving terminal on the superframe left to send voice data; c) in the super frame region filling within the time window, the sending end to the receiving end stop sending voice data. The invention can be used for satellite communications, especially satellite mobile communication systems.
