摘要
相较3G/4G时期,5G SA阶段网络架构、技术标准、VPDN业务实现方式等都发生了很大变化。首先深入调研国内VPDN业务开展现状,分析其业务需求、组网及计费特征,并对5G SA阶段核心网部署模式及3GPPR16相关的标准规范进行研究,提出了不同场景下5G SAVPDN业务的继承方案,并结合终端成熟度对5G阶段VPDN业务的开展模式和受限性进行了阐述,为5G SAVPDN业务开展及网络建设提供参考。
Compared with the 3G/4G period,the network architecture,technical standards and implementation methods of VPDN service in 5G SA phase have changed greatly.Firstly,it makes a deep investigation on the current situation of domestic VPDN busi-ness,analyzes its business requirements,networking and billing characteristics.Then,the core network deployment mode of 5G SA phase and 3GPP R16 related specifications are studied,and the inheritance schemes of 5G SA VPDN service in differ-ent scenarios are proposed.Finally,the development mode and limitation of 5G SA VPDN service are described in combination with terminal maturity,so as to provide a reference for 5G SA VPDN service development and network construction.
