三移动网合一——以体制创新带动西部IT产业的跨越式发展

Three MT in One"—The Leaping Development of IT Industry in western China driven by system innuvation

随着人类生活的高速化、信息化和移动化 ,包括个人视讯 (信息或娱乐 )在内的多媒体移动通信将成为人们不可或缺的生活需要。在移动的情况下 ,一切视讯 /通信都应是一个有机的整体 ,必然要求“三移动网含一”。又由于在移动网的情形下 ,技术最新、历史负担最小 ,“三移动网”也才有可能真正“合一”。同时 ,“移动 (无线 )接入”也将是现有网络的薄弱点———“接入网”的最佳手段和最后终结。基于国际上近年来实施数字地面电视积累的丰富经验 ,新一代“多载波扩频”技术为我国数字地面电视的发展开创了无限生机。以数字地面电视的分布化、双向化、基站化的“蜂窝单频网”为基础 ,在VHF/UHF波段上利用最先进的现代信号处理 /数字通信技术 ,将我国的移动地面电视 (MobileTelevision Terrestrial)、、移动通信 (MoblleTelecommunication)、移动因特网 (MobileTCP/IP)在全面的系统、协议、设备、终端、服务的意义上统一为整体 ,从国外的“多协议、多业务、多制式”的纷繁巢臼和历史负担中脱颖而出 ,把我国交互式地面电视网开发成一个无线、移动、宽带的双向数据通道———“三移动网合一 (ThreeMTinOne)” ,并采用光因特网 (IPoverOptical/IPoverDWDM)为主干网。本文在国内外率先提出了“三移动网合一”

With our social life comes to a more effcient,mobile and informative stage,the multimedia mobile communication,including personal videocommunication(informative and/or entertaining),shall be a indispensable daily requisite,Under the condition of mobility,all AV telecom/telecomnunication shall be a full organized integration thus the'Three MT in One'must become a necessity,In the mobile area,with the newest tcchnology and test historical burden,the implementation of 'Three MT in One'could be only possible. Meantime,'Mobile(Wireless)access'is also the best candidare and the ultimate solution of'Access Net'-the weak point and bottleneck of the existing network.Cuidea by the worldwide expcriences of Digtal Terrestrial TVs implementation recent years,our new technology called'Multi Carrier CDMA'makes use of the most advanced modern Siginal processing/Digital Communication techniquse in VHF/UHF TV symem,the'Cellular Single Frequcncy Network'inspires a prospective vista to the development of Chiness Dignal Terrestrial TV.This new technology integrates the Mobile Television Terrestrial.Mobile Telecommunication,and Mobile TCP/IP to a unique structure for China in the extent of system,protocol,equipment and service.Extricating from the complex imbroglio and historical predicament of 'Multi protocols,Multi scrvices,Multisystems'that many western countries have to suffer,the Chinese interactive terrestrial TV network is to go along with the new way of 'Three MT in One'which paves the wireless,mobile,wide band and bi directional data free way of China.The'IP over Optical'and'IP over DWDM'are adopted as its backbone network.This paper initially broaches a feasible scheme of'Three MT in One'both domestically and internationally.It jamps over the so called'4th generation'mobile communication,constructs a new domain of Information Industry on a base of our own Intelligeiice Property and may inaugurate a whole New World of our countrys economy.It also lifts a great banner of'Developing West China'and'coanstracting Silicon Valley of Sichuan'.
