摘要
本文首先介绍了应用于CDMA系统的声码器,然后结合一种基于IP的CDMA2000系统,描述了语音传输与控制流程,并讨论了在各种业务流控制模型中声码器的管理方法,说明该系统节约了声码器资源、简化了信令流程并提高了业务质量。
This paper introduces the vocoder applied in CDMA systems. With a model of CDMA2000 system based on IP, it describes the transmission and control of voice, then discusses the control method of vocoder applied in all kinds of control models of operation stream. It shows that this system saves vocoder resource and simplifies signaling flow and improves operation quality.
