网络虚拟化在运营商2G退网转型架构上的应用分析

Analysis on Application of Network Virtualization in the Transformation Architecture of 2G Network Shutdown for Operators

2G退网不仅仅会带来终端和无线网络结构的变化,对移动核心网也有很明显的网络架构转型需求。为了更好地帮助运营商实现快速的2G退网,降低移动网络运维投入,提升无线频谱利用率,增加运营商利润收入,讨论了如何使用虚拟化技术实现2G退网后的核心网转型,基于IMS的Vo LTE可以很好地解决4G语音业务问题。另外,网络虚拟化改造也将给这次转网提供强大的技术支撑。基于统一虚拟化云平台解决方案,移动运营商可以更快速地完成网络转型和新业务部署,平滑演进以解决2G退网4G广覆盖的技术需求。

2G network shutdown not only brings about the change of terminal and radio parts, but also evidently requires the network architecturc transformation of core networks. In order to help operators realize fast 2G network shutdown, reduce the operation and maintenance investment of mobile networks, enhance radio spectrum efficiency and increase operators＇ profit and revenue, virtualization technique was discussed to realize the transfbnnation of core networks after 2G network shutdown. YbLTE based on IMS can solve 4G voice service very well. In addition, the network virtualization also provides the powerful technical support to the network transformation. Based on the unified virtualized cloud platform solution, mobile operators can fast achieve the network transformation, the new service deployment and the smooth evolution to deal with the technical requirements of 2G network shutdown and 4G broad coverage.
