摘要: 为促进铁路综合数字移动通信系统(GSM-R)语音组呼业务(VGCS)正常运用,以保障在非正常状态下和紧急情况下处置危及铁路行车安全的重要事项顺利进行,通过分析GSM-R的VGCS实现原理和实施技术方案,结合2个在铁路通信网中实际发生的VGCS运用异常的典型案例,分析业务运用异常的案例问题发生的根源,重点研究GSM-R系统与调度通信系统间VGCS流程,并优化与调整实施方案。研究表明:通过优化与调整GSM-R与调度通信系统间VGCS实施方案,可避免在铁路枢纽或跨局地区等复杂条件下GSM-R的VGCS运用异常问题。

Abstract: In order to promote the normal use of GSM-R VGCS in railway integrated digital mobile communication system, ensure that under abnormal conditions and emergency situations to deal with the important issues endangering the safety of railway traffic smoothly, implementation principle and implementation technical scheme of GSM-R VGCS was analyzed, and two typical cases of abnormal application of VGCS in railway communication network was combined with, the root cause of the problem that focuses on VGCS flow between GSM-R system and scheduling communication system were mainly studied, and the implementation scheme was optimized and adjusted. The research shows that: by optimizing and adjusting the implementation scheme of VGSC between GSM-R system and dispatching communication system, the abnormal application of GSM-R VGCS under complex conditions such as railway hub or cross bureau area can be effectively avoided.

Key words: global system for mobile communications-railway(GSM-R), voice group call service(VGCS), dispatching communication main system, call organizing, number format
