摘要: 在铁路数字移动通信系统(GSM-R)中,分组域通用分组无线业务 (General Packet Radio Service,GPRS)系统主要承载调度、状态监测等非实时性业务,为提高研发效率,需要设计一种符合GSM-R要求的GPRS仿真系统。介绍GSM-R分组域仿真系统的系统架构,分析仿真系统的技术难点,阐述仿真系统在信令流程上与现网的区别,给出仿真通信系统无线与IP侧全协议栈的实现方法,构建出满足研发测试要求的GSM-R分组域仿真系统,同时对传输速率、网络时延等多项性能指标进行测试,表明所设计GSM-R分组域仿真系统能支持真实铁路应用产品在仿真环境中的无差异通信。

Abstract: In the railway digital mobile communication system (GSM-R), General Packet Radio Service (GPRS) system mainly carries non-real-time services such as scheduling and status monitoring. In order to improve the efficiency of research and development, a GPRS simulation system that meets the requirements of GSM-R is required. This paper first introduces system architecture of GSM-R packet domain simulation system, and explains the technical difficulties of simulation system, then describes the difference between simulation system and current network in the signaling process. The whole IP protocol simulation method is proposed and a GSM-R packet domain simulation system is built that meets the requirements of R & D and testing. Finally, the system performance indexes such as transmission rate and network delay are tested, which shows that the designed GSM-R packet domain simulation system can support non-difference communication of real railway application products in the simulated network environment.

Key words: GSM-R, GPRS, packet domain, network simulation
