5G公网铁路应用接入架构设计研究

Design and Research on Access Architecture of 5G Public Network Railway Application

为顺应铁路大规模开展5G公网业务应用的发展趋势,进一步加强铁路5G业务应用集中管控,提高5G公网铁路应用的一致性、安全性和规模效应,深入开展5G公网铁路应用架构研究。以实际铁路业务5G公网应用需求为驱动,以5G网络切片、边缘计算等技术为依托,基于铁路业务的部署特点及应用场景,提出广域号卡集、广域切片、局域切片、局域物理专网4种网络接入架构,并针对典型应用业务提出相应的5G公网接入方案。5G公网为铁路信息化业务提供了辅助承载能力,通过5G公网铁路应用架构设计,规范铁路业务使用5G公网的技术接口,为业务扩展、资费优惠、安全防护、运营管理、服务质量控制等工作提供技术支撑,有助于提升铁路智能化服务水平。

In order to cater to the development trend of large-scale 5G public network business application in railways,we further strengthen the centralized control of railway 5G business applications,improve the consistency,safety and scale effect of 5G public network railway application,and carry out in-depth research on the architecture of 5G public network railway application.Driven by the actual application requirements of 5G public network for railway business,relying on 5G network slicing,edge computing and other technologies,and based on the deployment characteristics and application scenarios of railway business,four network access architectures are proposed:wide area number card set,wide area slicing guarantee,local area slicing guarantee and local area physical private network,and corresponding 5G public network access schemes are proposed for typical application business.The 5G public network provides auxiliary carrying capacity for railway information business.Through the architecture design of the 5G public network railway application,the technical interface of 5G public network is standardized for railway business,which provides technical support for business expansion,tariff preference,safety protection,operation management,service quality control and so on,contributing to improving the level of railway intelligent service.
