5G边缘计算组网关键技术研究

Research on Key Technologies of 5G Edge Computing Networking

为了满足边缘计算的需求,需要5G网络具备相应的业务分流能力。通过对MEC系统结构的梳理,对MEC应用场景进行了归类,通过对多种5G PDU会话建立及业务分流技术的对比分析,介绍了对应各类MEC应用场景的5G UL CL分流组网技术和多DNN组网技术,并指出了现有5G分流技术的不足之处,最后介绍了5G UPF下沉的部署方式和5G网络提供的二次认证/授权功能。

In order to meet the requirements of edge computing, 5G network needs to have the traffic steering capability. By reviewing the mobile edge computing(MEC) system architecture, the MEC application scenarios are classified. Through the comparative analysis of various technologies on 5G PDU session establishment and traffic steering, the 5G UL CL traffic steering and networking technologies and multi-DNN networking technology are introduced as well as the corresponding MEC application scenarios. Also, the shortcomings of current 5G traffic steering technologies are pointed out. Finally, the sinking deployment mode of 5G UPF and the secondary authentication/authorization function provided by 5G network are introduced.
