端到端网络切片关键技术及应用

End to end network slicing key technology and applications

5G网络承载着"万物互联"的愿景,使移动通信的服务范围从人与人通信延伸到物与物、人与物智能互联,渗透至更加广阔的行业和领域。为此,5G应具备更强的灵活性和可扩展性,以适应海量的设备连接和多样化的用户需求。按需、定制、差异化的服务将是未来运营商业务提供的重要模式,也是运营商新的价值增长点。端到端网络切片是实现这一目标的关键技术。本文对网络切片技术进行研究,从架构、使能技术和应用3个方面,对网络切片技术在5G时代的作用进行了深入分析。

The 5 G network bears the vision of"Internet of everything",which enables the service scope of mobile communication to extend from human-to-human communication to the intelligent interconnection of things and human.To this end,5 G should be more flexible and scalable to accommodate the massive number of device connections and diverse user needs.On-demand,customized,and differentiated services will be an important model and a new value growth point for operators.End-to-end network slicing is a key technology to achieve this goal.This paper studies the network slicing technology,and analyzes the role of network slicing technology in the 5 G era from three aspects:architecture,enabling technology and application.
