高速铁路通信系统从GSM-R到5GNR-R演进研究

Research on the Evolution of High-Speed Railway Communication System from GSM-R to 5GNR-R

高速铁路(HSR)提高了铁路服务的质量,提高了客户满意度,并有助于建立社会经济平衡的社会。这种高效的运输方式在投资、技术、行业和环境方面都带来了重大挑战。为了处理不断增加的交通量,确保乘客安全并提供实时多媒体信息,需要用于HSR的新通信系统。在过去的十年中,公共网络已经从以语音为中心的第二代系统(例如功能有限的全球移动通信系统(GSM))发展到提供更高数据速率的第五代宽带系统(例如第5代移动通信技术(5GNR))。因此,对于HSR而言,用具有更高容量和能力的下一代铁路专用通信系统5GNR铁路(5GNR-R)替代当前的GSM铁路(GSM-R)技术非常重要。

High-speed railway(HSR)improves the quality of railway services,improves customer satisfaction,and helps build a society that is socially and economically balanced.This efficient mode of transportation has brought major challenges in terms of investment,technology,industry,and the environment.In order to handle the ever-increasing traffic volume,ensure passenger safety and provide real-time multimedia information,a new communication system for HSR is required.In the past decade,public networks have evolved from voice-centric second-generation systems(such as the Global System for Mobile Communications(GSM)with limited functions)to fifth-generation broadband systems that provide higher data rates(such as the 5th generation).Generation mobile communication technology(5GNR)).Therefore,it is very important for HSR to replace the current GSM railway(GSM-R)technology with 5GNR railway(5GNR-R),a next-generation railway dedicated communication system with higher capacity and capabilities.
