摘要
第五代移动通信(5G)具有低时延、高速率的特点,同时在我国5G发展具有良好的政策环境和商业环境。5G技术铁路应用已具备良好的基础和技术支撑,将5G技术应用到铁路有利于提升安全保障水平、运营效率、智能化水平并促进5G相关产业链的发展。对铁路5G专网架构、互联互通接口及协议栈进行论述,结合技术特点和信令流程提出铁路5G专网互联互通测试方案,提出将开源平台应用到铁路5G专网互联互通测试的方法,能够提高测试效率,扩大测试覆盖范围。
The 5th-generation mobile communication(5G)features short latency and high speed.Meanwhile,5G development enjoys favorable policy environments and business environments in China.Railway application of 5G technology,which has solid foundation and technical support,helps improve railway safety,operation efficiency,and intelligence level,and promote the development of 5G-related industrial chains.This paper mainly discusses the railway 5G private network architecture,interoperability interfaces and protocol stacks,proposes a railway 5G private network interoperability test plan based on technical characteristics and signaling process,and proposes a method for applying the open source platform to the railway 5G private network interoperability test,thus improving test efficiency and expanding test coverage.
