基于GSM-R的CIR动态线路数据传输可行性方案研究

Feasibility Study on CIR’s Dynamic Line Data Transmission over GSM-R

目前,机车综合无线通信设备中线路数据存储采用本地静态线路数据库方式,存在维护管理难度大、成本高等不足。对GSM-R系统点对点短消息、GPRS和小区广播短消息3种数据传输方式承载动态线路数据传输业务的可行性进行了研究,并提出了基于GSM-R的CIR动态线路数据传输的可行性方案,能够对线路数据库进行集中维护和管理。

At present,the line data in the Cab Integrated Radio communication equipment is stored in the form of local static database,which results in the difficulties of maintenance management and high cost.So,a study is made on the feasibility of CIR’s dynamic line data transmission over GSM-R’s three services of data transmission:point-to-point short message,cell broadcast short message,and GPRS.Finally,a feasibility scheme for CIR’s dynamic line data transmission over GSM-R is presented.
