LTE-R系统架构研究

Research on LTE-R System Architecture

简要介绍国内外铁路下一代移动通信系统的研究现状,提出我国的LTE-R系统架构,主要包括EPC系统、无线接入网和用户设备。为实现语音业务,重点分析EPC的构成,引入IMS系统。对无线接入网的组成进行描述,并提出用户设备的分类和功能需求。对LTE-R系统架构研究具有参考意义。

This paper briefly introduces the research status of the next generation mobile communication system for railways at home and abroad, and puts forward Chinese LTE-R system architecture, including EPC system, radio access network and user equipment. In order to realize voice services, it analyzes the structure of EPC, introduces the IMS system and the composition of the radio access network, and proposes the classification and functional requirements of user equipment. The paper can provide significant reference for the research on LTE-R system architecture.
