Description

语音编码速率调整的方法和设备 技术领域
本发明涉及移动通信系统，尤其涉及一种语音编码速率调整的方法和设备。
背景技术
为了提升用户的通话感受，引入了一种免码变换操作(Transcoder Free Operation，TrFO)技术。如果发送端用户设备(user equipment，UE)和接收端UE支持相同的语音编码速率，则在建立业务承载的过程中不进行码变换操作，使用相同的语音编码速率进行语音通话。由于TrFO技术中只在发送端UE进行编码，避免了传统呼叫过程中因重复编码操作对语音信号造成的损害，显著提高了语音信号的质量。
在TrFO技术的应用过程中，发明人发现：若发送端UE采用的语音编码方式是接收端UE无法正确解码的语音编码速率，则接收端UE会发送消息请求发送端UE调整语音编码速率。在某些情况下，会出现发送端UE不及时调整语音编码速率，例如，发送端UE拒绝进行语音编码速率调整，导致接收端UE无法正确解码发送端UE发送的语音数据，从而造成语音单通的问题。
