面向垂直行业的N4接口解耦技术

N4 Interface Decoupling Technology for Vertical Industries

为了满足5G网络服务垂直行业场景下对边缘UPF轻量化、低成本和灵活部署的需求,需要推动支持N4接口解耦和轻量化UPF。首先对UPF进行了功能简化和分级,并提出分档容量和性能要求,然后对N4接口实现模型及流程进行了介绍,明确了轻量化UPF功能要求、N4接口解耦技术要求,可有效地指导UPF产品开发,加速产业成熟,最后对支持N4解耦的轻量化UPF典型部署模式进行了探讨。希望通过推动N4解耦,共同促进UPF朝着更加开放、灵活的方向发展,创造开放繁荣的5G边缘生态。

In order to meet the requirements of the edge UPF with lightweight,low cost and flexible deployment for the vertical industry in 5G network,it is necessary to promote N4 interface decoupling and lightweight UPF.First,the UPF functions are simplified and classified,the graded capacity and performance requirements are proposed.Then the implementation models and procedures of N4 interface are introduced,the requirements of lightweight UPF functions and N4 interface decoupling technologies are clarified to effectively guide the product development of UPF and accelerate the industry maturity.Finally,this article discusses the typical deployment patterns of lightweight UPF with N4 interface decoupling.It is hoped that promoting N4 interface decoupling facilitates UPF in a more open and flexible direction,and creates an open and prosperous 5G edge ecology.
