应急通信场景下的5G轻量核心网应用研究

Research on lightweight 5GC application in emergency communication

应急通信保障存在快速部署、快速上线、简化配置流程的需求,而基于3GPP标准的组网架构太过庞大和复杂,难以满足需求。轻量化5GC旨在参考标准架构,基于通用硬件平台搭载虚拟化技术,实现软硬件解耦,控制与转发分离的云化核心网,并通过整合、裁剪网元功能来减少业务流程,提升业务处理能力,成为应急通信行业新的解决方案。从基于构建应急通信专网应用场景入手,分析轻量5G核心网的实现架构和关键技术,并结合应急保障典型案例进行部署方案的探索。

Emergency communication support requires rapid deployment,quick on-line and simplified configuration process,but the network architecture based on 3GPP standard is too large and complex to meet.Lightweight 5GC aims at referring to the standard architecture,carrying virtualization technology based on the common hardware platform,realizing the decoupling of hardware and software,controlling and forwarding the cloud core network,and reducing the business process and improving the business processing capacity through the integration and tailoring of network element functions,becoming a new solution for the emergency communication industry.Based on the application scenario of emergency communication private network,this paper analyzes the implementation architecture and key technologies of lightweight 5G core network,and explores the deployment scheme based on typical cases of emergency support.
