文档介绍：GSM-R GSM-R 系统在武广高铁的应用系统在武广高铁的应用 GSM-R system in the GSM-R system in the Wuhan Wuhan - - Guangzhou high-speed rail Guangzhou high-speed rail GSM-R 系统在武广高铁的应用,为我国高速铁路实现铁路信息化建设跨越式发展做出了一个成功的典范。采用所谓“天网”的 GSM-R 通信网络,实行高速动车组准确定位和控制。武广高速铁路通信网络的应用突出了安全、完整、统一、灵活、可靠、可扩展性的特点。 GSM-R 系统为铁路沿线人员(包括铁路工作人员、旅客、其他用户) 提供了语音和数据通信技术服务,为基于 GSM-R 的 CTCS-3( 列车运行控制系统)级列控提供了通信平台 GSM-R system in the Wuhan -Guangzhou high-speed rail applications for the realization of China's high-speed railway construction railway information by leaps and bounds made ?? a essful model. The so-called " " of GSM-R work, the implementation of high-speed EMU accurate positioning and control. Application of the Wuhan -Guangzhou high-speed work highlights the security, integrity, unity, flexible, reliable, scalable features. GSM-R system along the railway personnel (including railway staff, visitors, other users) provides voice and data communications technology services for GSM-R based on the CTCS-3 (Train Control System) level provides munication platform for train control . 一,应用于武广高铁 GSM-R 通信系统的特点 GSM-R ( Globle System of Mobile foRRailway )专门针对铁路移动通信的需求而推出的专用通信系统,由国际铁路联盟( UIC )和欧洲电信标准化组织制定技术标准,并被许多欧洲国家采纳。它基于 GSM 并在其功能上有所超越,是成熟的通过无线通信方式实现移动话音和数据传输的一种技术体制。 First, apply to the Wuhan -Guangzhou high-speed railway GSM-R communication system is characterized by GSM-R ( Globle System of Mobile foRRailway ) specifically for the needs of railway mobile communications and the launch of a munication system by the International Union of Railways (UIC) and the European munications anization development of technical standards, adopted by many European countries. It has been exceeded based on the GSM and its function is to realize a sophisticated technical system mobile voice and data transmission via munication. (一)铁路 GSM-R 相对公网 GSM 有着特殊的需求用户级别不同(语音呼叫,包括:组呼、群呼、增强多优先级与强拆)。功能寻址(调度)。基于位置的寻址(机车呼叫前方车站、后方车站)。高速列车运行情况下的移动通信。大量特殊的数据业务需求(列控、车次号等)。(A) railway GSM-R GSM work has a relatively specific needs
