摘要
GSM-R应用过程中,在频率规划、传输速率和系统应用等方面受到较大限制,我国铁路已确定下一代专用移动通信系统的发展方向为LTE-R。从带宽、网络结构和系统承载的业务等方面分析LTE-R系统与GSM-R系统的异同;基于LTE-R所承载的业务,前瞻性地研究了LTE-R相关检测技术及其检测系统的架构和组成,为LTE-R系统日常动态检测提供技术积累和系统支撑。
The GSM-R technology is limited in terms of frequency plan, transmission rate and system application, as the application results show. Theretbre, the LTE-R technology has become the development direction of the next generation railway communication system. The paper compares LTE-R and GSM-R with respects to bandwidth, network structure and services provided by the system, etc. Based on the services provided by LTE-R, the paper studies in a forward-looking way the LTE-R related detection technologies and structure of the detection system, providing technical Ibundation and support fbr routine dynamic detection of LTE-R system.
