摘要
目前我国既有第二代移动通信系统产业链已表现出萎缩趋势,及时完成铁路下一代移动通信技术应用准备,对促进我国铁路移动通信系统发展具有重要意义.本文阐述了发展我国铁路下一代移动通信系统的迫切性,对当前主流宽带移动通信系统的发展现状进行了分析,结合我国铁路主要应用场景业务需求特点,对第4代及第5代移动通信技术在铁路应用的适用性进行了分析.提出在试验验证基础上抓紧申请铁路适用频率,建议铁路正线采用以3GPP (third generation partnership project) LTE (long-term evolution)为基础的集群通信系统并采用3GPP组呼方案,在站场及枢纽地区可采用包括第5代移动通信技术(5G)在内的多种通信技术.提出结合现场高速试验、开展技术及装备研究/制,研究制订相应技术标准体系,研究第5代移动通信等新技术在铁路的工程应用.
At present, the industrial chain of second-generation mobile communication systems in China is in a state of atrophy. Hence, application-oriented research of next generation railway mobile communication systems （NGRMSs） is of great significance to the development of railway mobile communication systems in China. The urgency of developing NGRMSs in China is presented. The state-of-the-art popular mobile communication systems were reviewed. The adaptability of fourth generation （4G） and fifth generation （SG） communication systems for railway applications were analysed taking the requirements of future railway systems in China into consideration. Based on the analyses, the following developments were proposed. A practical and dedicated spectrum should be applied for NGRMS based on the trial line verification results. Third generation partnership project （3GPP）, long-term evolution （LTE）, and 3GPP group communication schemes should be used in NGRMSs for realising tranking communications in railway intervals. Furthermore, multiple wireless communication standards, including 5G communication systems, should be made functional in railway yards and terminals. Technological and equipment research should be carded out with field trial at high-speed line. Technical standards for NGRMSs should be established. Finally, research should be performed on the applications of 5G and other new technologies in railway engineering.
