LTE-R应用于中国铁路的技术分析

摘要

LTE-R is the main development trend for the next generation railway mobile communication system. The article introduces the technical features of LTE-R and its technical superiority in relation to conventional mobile communication. It specifies the railway businesses applicable to LTE-R,making a comparison of service patterns that may be adopted. By analyzing multiple aspects including technical features,network structure and so on,it make a discussion about the feasibility of LTE-R application in domestic railways,with proposals made for network evolution.%LTE-R是下一代铁路移动通信系统的主要发展方向。介绍LTE-R的技术特点及其相对于传统移动通信的技术优势，阐述LTE-R可承载的铁路业务，并对可能采用的制式进行对比。通过对技术特点、网络结构等多方面的分析，对LTE-R应用于中国铁路的可行性进行探讨，并对网络的演进提出建议。
