铁路5G-R互联互通测试体系思考

Exploration on Railway 5G Interoperation Test System

随着5G标准的不断完善,全球移动运营商5G网络设备已经成熟,我国铁路将5G作为铁路专网新一代移动通信技术制式,铁路专用应用设备研发正在进行,铁路5G-R设备的互联互通亟待开始,为5G-R系统的部署创造条件。依据5G-R系统架构和互联互通测试理论,给出了5G-R互联互通测试框架,创新定义一种互联互通测试方法—积木堆叠法,并使用该方法设计测试框架中“已验证5G-R系统”搭建流程,为5G-R互联互通测试提供可靠的测试系统。在此基础上,给出5G-R系统待测设备的互联互通测试接口、测试方案,同时给出互联互通测试规范设计流程,静态、动态测试环境框架,为铁路互联互通测试工作的整体设计和开展提供思路。

With the continuous improvement of 5G standards,5G network equipment of global mobile operators has become mature.Chinas railways take 5G as a new generation of mobile communication technology for railway dedicated network,the R&D of railway application equipment is under way,and the 5G-R equipment interoperation test needs to be started urgently to provide conditions for the deployment of future 5G-R system.Based on the system architecture of 5G-R network and the theory of interoperation test,this paper presents the test architecture of 5G-R interoperation,innovatively puts forward one test method named the building block to set up processes for the verified 5G-R system described in the test architecture.According to the building process of the building block method,this paper lists the interoperation test interface and key test content of the test interface for the equipment to be tested,offers the design process of the interoperation test specification and the test framework of interoperation static and dynamic test environment.
