D2D ProSe技术与铁路应用场景分析

D2D ProSe Technology and Its Railway Application Scenario

基于国内外铁路对新一代移动通信系统的需求,深入研究3GPP相关技术规范,提出将D2D ProSe应用到铁路新一代移动通信系统。对D2D ProSe的关键技术、网络架构、接口和技术优势进行论述;结合技术特点,分别在网络故障和网络工作正常情况下,分析其在铁路的潜在应用,并给出相应作业的D2D ProSe通信流程;提出D2D ProSe在铁路应用面临的关键问题。D2D ProSe不但可有效解决脱网通信问题,而且可以拓展铁路新一代移动通信系统的应用范畴,提高网络健壮性和业务容量,实现基础设施共享,降低建设和维护成本。

Based on the requirements for the new-generation mobile communication system of railways in China and abroad,3GPP related technical specifications have been deeply studied,and D2D ProSe is proposed to be applied to the new-generation mobile communication system of railways.The paper discussed key technologies,network architecture,interfaces and technical advantages of D2D ProSe;in combination with the technical characteristics,the potential application in railways was analyzed respectively under network failure and normal network operation,and corresponding D2D ProSe communication flow was given;the key problems faced by D2D ProSe in railway application were put forward.D2D ProSe can not only solve the issue of offnetwork communication,but also expand the application scope of the new-generation mobile communication system of railways,improve network robustness and business capacity,realize infrastructure sharing,and reduce construction and maintenance costs.
