摘要
3GPPEPS标准是CDMA网络演进的主要目标。本文分析了CDMA网络演进的总体趋势和方向,研究了CDMA向EPS演进中语音和数据业务互操作的需求和各演进阶段的网络特征,给出了可能的分阶段网络演进架构。
Evolved Packet System (EPS) standards introduced by 3GPP are the main long term evolution of CDMA network. The trends and directions of CDMA evolution are analyzed. The interworking requirements of voice and data services in the process of evolution from CDMA to EPS and the features of networks in different evolution stages are studied. The possible architectures of corresponding stage are given.
