摘要
主要介绍了语音组呼业务、基于位置的寻址和基于位置的呼叫限制三类铁路特殊应用的基本概念,在分析其实现方式的基础上,对其如何在GSM-R系统编号方案中实现做了探讨,最后结合CIR车载设备阐述了GSM-R系统编号方案在实际应用中的意义。
The basic concept of voice g up call service, location based addressing and location based call restriction are introduced firstly. On the basis of analyzing their realization methods, we discuss how to implement these special railway services in the GSM-R numbering scheme. Fi- nally, the significance of the GSM-R numbering scheme in practical application is explored in combination with on-board CIR equipment.
