摘要:

EPS系统的优点之一是可以支持非3GPP无线网络接入,其中包括CDMA网络,而EPS的核心网EPC是3GPP和3GPP2在核心网层面实现融合的基础。由于CDMA和EPC是两个标准组织分别制定的技术标准,因此需要一些特别的关键技术来实现CDMA网络接入EPC,其中包括PMIP隧道、承载管理、多PDN连接以及CDMA与EPC网络之间的QoS转换等,本文将通过对这些技术的介绍,分析CDMA网络在接入EPC时如何实现3GPP2技术和3GPP技术的转换和承接。

Abstract:

One of the remarkable characteristic of EPS system is supporting the non-3gpp radio network access,including the CDMA network. EPC which is the core network of EPS is the foundation of the 3GPP and 3GPP2 network integration in core network level. As CDMA and EPC are constituted by the different standard organization,some special technologies should be deployed to realize the CDMA accessing EPC,including PMIP channel,bearer administration,muti-PDN connection and QoS parameter’mapping between the CDMA and EPC network.This paper focuses on those key technologies about network integration of CDMA accessing to EPC.
