长三角一体化核心网规划建设研究

Research on Planning and Construction of Integrated Core Network in Yangtze River Delta

长三角城市群之间经济联系十分紧密,人员流动频繁,跨省通信业务需求旺盛。传统上以省为单位进行核心网网络规划建设资源利用率低,专业化运营能力不强,无法快速推出业务适应市场竞争,不能充分发挥网络虚拟化后电信云的能力与优点。详细分析了核心网网络功能虚拟化、软件化、集中化、云化的演进趋势,给出了长三角一体化核心网规划建设目标和策略,针对长三角一体化核心网推进过程中存在的问题,给出了解决建议。

Due to the strong economic ties between the city groups in the Yangtze River Delta and large flow of traveler,there is exuberant demand for cross provincial communications service.The disadvantage of lower resources utilization ratio and lack of professional operation ability is being revealed in the system of traditional planning and construction system of CN which is based on the unit of provinces.The system is showing a weak ability in either meeting the demand of quick launch of service,or bringing on the advantage of network technology evolution.It analyzes the network evolution in network function virtualiza-tion,software defined network,cloud computing,and gives a goal and strategy of the integration planning and construction of the core network in the region of Yangtze River Delta.Meanwhile,it provides solutions on the possible problems brought on in the process of core network integrating.
