摘要
本文介绍了基于IP架构的分组语音核心网的TrFO特性,并结合自行开发的cdma20001x系统,讨论了TrFO特性在基于IP架构的cdma20001x移动通信中的具体实现方案,详细讨论了多种声码器的灵活配置策略,并对各种策略进行了模拟比较,模拟结果对实际工程实现具有重要意义。
The TrFO characteristic in the IP-based packet speech core network(CN) is introduced. Taking the self-developed system as an example, a scheme for implementing TrFO in the IP-based cdma2000 1x system is discussed, strategies of multi-vocoder unbended configuration are explained and simulated.The results are very important for the practical work.
