摘要
5G时代将是一张网络满足多样化业务需求,基于NFV/SDN技术,采用通用硬件,实现网络功能软件化和基于差异化业务的资源编排。业务及网络平台运营通过数字化平台实现网络能力和业务需求的对接,开放网络能力,按用户面部署,减小业务时延。降低传输网压力,打破传统数据仅能从省级出口的路径,用户及业务数据下沉到本地,高频和低频混合组网。5G核心网与NFV基础设施结合,为普通消费者、应用提供商和垂直行业需求方提供网络切片、边缘计算等新型业务能力。5G核心网将从传统的互联网接入管道转型为全社会信息化的赋能者。
In the 5 G era, a network would meet the needs of diversified services. Based on NFV/SDN technology and general hardware, network functions would be softened and resource arrangement based on differentiated business be realized. Business and network platform operations realize the docking of network capabilities and business requirements through digital platform, open network capabilities, deploys according to users, reduces service delay, and decreases the pressure on the transmission network. By breaking the traditional data only from the provincial export path, users and business data sink to the local, thus to achieve high frequency and low frequency hybrid networking. The 5 G core network combines with NFV infrastructure to provide new business capabilities such as network slicing and edge computing for the ordinary consumers, application provider and vertical industry demanders. The 5 G core network would be transformed from the traditional Internet access pipeline into an enabler of information technology in the whole society.
