【正文】 er service image project. China Railway after speed increasing, points to the environment has been greatly improved provides, at the same time, accurate, realtime passenger information has bee indispensable to the development of a step, so to further deepen construction of passenger information system is being one of the railway development of the more important issue. This thesis from the status quo of the highspeed rail passenger information system of IPTV technology is introduced to the train of the new media, also according to the actual situation of the railway passenger information system, and through the key technologies of 4G munication research, hypothesis of the development of railway munication, design based on a set of 4G munication technology and scheme of IPTV use of the highspeed rail passenger information system. 4G as a new generation of munication technology, the more rapid speed of wireless munication won the favor of more and more people, but also promote the China munication industry scale expansion and rapid development of, if the 4G used in railway munication system will add more high work efficiency for the railway transportation system. Keywords: Passenger information system 4G IPTV High speed railway 目 錄 第一章 緒論 ............................................................................................................... 1 鐵路旅客信息系統(tǒng)的發(fā)展 ................................................................................... 1 4G通信技術(shù)發(fā)展背景 ......................................................................................... 1 IPTV技術(shù)發(fā)展背景 ............................................................................................. 2 課題研究意義 ..................................................................................................... 3 課題發(fā)展前景 ..................................................................................................... 4 論文完成的主要研究內(nèi)容 ................................................................................... 4 第二章 關(guān)鍵技術(shù)及原理 ................................................................................................. 6 4G通信的核心技 術(shù) ............................................................................................. 6 4G通信的網(wǎng)絡(luò)結(jié)構(gòu) ............................................................................................. 8 IPTV的關(guān)鍵技術(shù) ................................................................................................ 9 IPTV技術(shù)的整體架構(gòu) ....................................................................................... 10 業(yè)務(wù)運營平臺 ........................................................................................ 11 IPTV網(wǎng)絡(luò)邏輯結(jié)構(gòu) ................................................................................ 12 第三章 高鐵旅客信息系統(tǒng)方案設(shè)計 .............................................................................. 13 旅客信息系統(tǒng)介紹 ............................................................................................ 13 旅客信息 系統(tǒng)的功能 ........................................................................................ 13 旅客信息系統(tǒng)的設(shè)計 ........................................................................................ 13 ....................................................................... 15 ........................................................................... 15 IPTVR系統(tǒng)的研究 ........................................................................................... 16 IPTVR系統(tǒng)功能 .................................................................................... 17 .......................................................................................................... 17 第四章 鐵路下一代移動通信系統(tǒng) LTER......................................................................... 19 鐵路通信網(wǎng)絡(luò)現(xiàn)狀與存在問題 .......................................................................... 19 引用 4G技術(shù) .................................................................................................... 19 高鐵 4G專網(wǎng)覆蓋 ............................................................................................. 20 本章小結(jié) .......................................................................................................... 21 第五章 結(jié)束語 ............................................................................................................. 22 總結(jié) ................................................................................................................. 22 展望 ................................................................................................................. 22 謝辭 ............................................................................................................................... 23 參考文獻(xiàn) ........................................................................................................................ 24 大連交通大學(xué) 2020 屆本科生畢業(yè)設(shè)計（論文） 1
