【正文】 e train number functions, scheduling order transfer function, the train tail device messaging function, shunting lootives, signal and control information system transfer capabilities, as well as train control data transmission function.GSMR dispatch munication system is mainly responsible for the train dispatching munications, scheduling munications for cargo, traction substation dispatch munications, scheduling and private munication, station munications, emergency munications, construction maintenance munications, and crossing munications. Dispatching munication system work using GSMR, both can take full advantage of the wireless, can also be bined with wired together to acplish the scheduling munication tasks.Functional addressing is very important for advanced addressing, trunked dispatch munication technology and the necessary means. In the business of functional addressing, each MSISDN can be established with more than one function number mapping, but a function of number can only be assigned to a user. Functional addressing business is divided into a voice calling capabilities addressing and the short message function addressing.The basis of the papers from the GSMR that is GSMR theory, work structure and functions on GSMR railway munication, and the status of the QinghaiTibet railway 蘭州交通大學(xué)畢業(yè)設(shè)計3munication on the part of the GSMR function in the QinghaiTibet railway munication the application has been designed. When a work is pleted, the work of pipeline management and maintenance is very important, therefore, at the end of the paper on this to make the design.Keywords: GSMR。論文從 GSMR 的基礎(chǔ)即 GSMR 原理、網(wǎng)絡(luò)結(jié)構(gòu)和功能等入手，闡述了 GSMR在鐵路通信中的應(yīng)用,并結(jié)合青藏鐵路通信的現(xiàn)狀對 GSMR 的部分功能在青藏鐵路通信中的應(yīng)用進行了設(shè)計。利用 GSMR 進行調(diào)度通信系統(tǒng)組網(wǎng)，既可以完全利用無線方式，也可以同有線方式結(jié)合起來，共同完成調(diào)度通信任務(wù)。GSMR 目前在我國鐵路通信中的應(yīng)用主要有：調(diào)度通信功能、車次號傳輸與列車停穩(wěn)信息的傳送功能、調(diào)度命令傳送功能、列車尾部裝置信息傳送功能、調(diào)車機車信號和監(jiān)控信息系統(tǒng)傳輸功能以及列車控制數(shù)據(jù)傳輸功能等等。由于 GSMR 可實現(xiàn)跨越國界的高速和一般列車之間的通信，能將現(xiàn)有的鐵路通信應(yīng)用融合到單一網(wǎng)絡(luò)平臺中，以減少集成和運行費用，而且由于 GSMR 是由已標(biāo)準(zhǔn)化的設(shè)備改進而成，GSM 平臺上已經(jīng)提供了大量的業(yè)務(wù)，因而引入鐵路專用的功能時只需最低限度地改動，故能保證價格低廉、性能可靠地實現(xiàn)和運行。GSMR 調(diào)度通信系統(tǒng)主要負責(zé)列車調(diào)度通信、貨運調(diào)度通信、牽引變電調(diào)度通信、其他調(diào)度及專用通信、站場通信、應(yīng)急通信、施工養(yǎng)護通信和道口通信等。功能尋址業(yè)務(wù)分為語音呼叫功能尋址和短消息功能尋址。蘭州交通大學(xué)畢業(yè)設(shè)計2AbstractGSMR (GSM for Railway) is a system which adds the scheduling munication function and the elements used in suitable for highspeed environment to the GSM cellular system, and is able to feet with the special railway scheduling munication technology requirements of the International Union of Railways. Because GSMR can control the munication between the crossborder highspeed trains with the general trains, can integrate the existing railway munications applications into a single work platform, to reduce integration and operating costs. And GSMR is the improvement made by the standardization of equipment, and the GSM platform has provided a lot of business, thus only need minimally changing during the introduction of the railway special features, and it can ensure low prices, and reliable performance to achieve and operation .Currently the using of GSMR is in China39。 Maintenance.目錄摘要 .............................................................................................................................................11 緒論 .......................................................................................................................................1 引言 .................................................................................................................................1 鐵路通信的發(fā)展歷程和現(xiàn)狀 .........................................................................................1 現(xiàn)代鐵路運輸對無線通信的發(fā)展要求 .........................................................................2 GSMR 的發(fā)展歷史及技術(shù)特點 ....................................................................................42 GSMR 系統(tǒng)概述 .................................................................................................................5 GSMR 基本原理 ............................................................................................................5 帶狀覆蓋 ..................................................................................................................6 面狀覆蓋 ..................................................................................................................8 GSMR 的網(wǎng)絡(luò)結(jié)構(gòu)及功能 ..........................................................................................14 BSS 結(jié)構(gòu)和功能 ...................................................................................................16 NSS 結(jié)構(gòu)和功能 ...................................................................................................17 OSS 結(jié)構(gòu)和功能 ...................................................................................................183 GSMR 在青藏線中的應(yīng)用 ...............................................................................................19 青藏線 GSMR 系統(tǒng)介紹 .............................................................................................19 GSMR 設(shè)計的主要原則及標(biāo)準(zhǔn) ..........................................................................19 GSMR 傳輸網(wǎng)絡(luò) ..................................................................................................20 GSMR 基站的設(shè)置 ..............................................................................................21 越區(qū)切換 ................................................................................................................22 GSMR 在青藏鐵路上的的應(yīng)用及設(shè)計 ......................................................................22 調(diào)度通信 ................................................................................................................22 功能尋址 ................................................................................................................27 調(diào)度命令傳送 ........................................................................................................35 列尾裝置信息傳送 ........................
