基于NFV的移动网络新型架构与关键技术研究

网络功能虚拟化技术在实现网元软件功能与专用硬件设备解耦的同时,驱动了移动网络架构设计方法的创新。本文提出一种基于虚拟化网元功能重构思想的网络架构设计思路,重新定义了与接入无关的统一控制平面和全局扁平的传输平面。新型架构方案具备以用户为中心、全局数据流路由优化、多接入系统融合、网络功能开放可编排等特性。

Research on NFV Based Mobile Network

Network Function Virtualization technology, which achieve the decoupling of the network software ruction from the dedicated netwrok equipment, is considered as a innovation to drive the re-architecture of the next generatoin mobile network. In this paper, we propose a new architeture concept based on the idea of virtualized network functoin reconstruction which re-define the RAT independent network control function plane and all fiat transprot plane.This architeture concept have many new features such as customer-centric service provision, global data flow routing opmization, multi-RAT coordination and network function orchestration.
