摘要
为解决5G公网网络稳定性不足,且5G-R频谱与网络资源受限的问题,通过分析3种5G专用网络部署方案的特点,并结合铁路业务对5G非公共网络组网的需求,基于公网集成非公共网络模式(PNI-NPN),探讨适用于铁路行业的5G公网专用部署方案,分析研究其可行性及应用前景;针对5G公网专用方案,提出相应的安全需求。该方案的探讨为铁路5G网络信息化建设提供参考。
In order to solve the problems of insufficient 5G public network stability and limited 5G-R spectrum and network resources,through analyzing the characteristics of three types of 5G private network deployment schemes,combined with the business needs of the railway industry for 5G nonpublic network networking,based on public network integrated non-public network(PNI-NPN),this paper discusses the 5G private public network deployment scheme suitable for the railway industry,analyzes and studies its feasibility and application prospects,and puts forward the corresponding security requirements for the 5G private public network scheme.The discussion of this scheme provides a reference for the future railway 5G network informatization construction.
