信息化是当今世界发展的重要主题,进入20世纪90年代以来,全球的信息化建设已经拉开了序幕,只有拥有信息资源开发和网络应用优势,才能掌握信息化建设的主动权。信息化,尤其是信息基础设施的建设,已成为各国综合国力的象征。作为信息业的主产业移动通信的发展自然成为重中之重。第三代移动通信是当前全球信息通信产业领域的热点,也是各方面关注的焦点。数字化和网络化已成为不可逆转的趋势,3G网络将为用户提供表现力更加丰富的音频、视频等多媒体内容的业务。
第三代移动通信(3G)的发展经历了体制标准之争,已逐步演进到标准的完善和设备开发之争以及未来的产业发展之争。面对激烈的竞争形势,快速提供业务、减少带宽资费、提高通信服务质量成为移动运营商在市场竞争中获胜的关键因素,这些关键因素之争的焦点又集中在基础网络建设,传输网是电信网的基础网络,因此,3G传输网的建设在整个3G网络发展中扮演重要角色。
全文以第三代移动通信(3G)网络建设为主题,进行分析和讨论。介绍了,3G发展状况和其所处的国内及国外的良好而深具挑战性的发展环境。较为系统地对3G网络建设所用到的主要技术进行了全面的叙述和分析。

The Third Generation Mobile Telecommunication (3G) Network Technology
The information-based is the important topic that world develop nowadays, which enters since 90's in 20 centuries. The information-based construction of the world has already drawn back the prologue, only owning the information resources development and networks to apply the advantage, then can control active power of the information-based construction. information-based,has been the standard every countries The development nature that is the main industry of the information industry to move the correspondence becomes heavy to win of heavy.
The development of the third generation mobile communication experienced the competition of the system, it have already gradually evolved the standard of perfection, the development of the equipments and the competition of the future industry development. Facing the vigorous competition situation, it becomes a triumphant key factor in the market that is quickly providing the business, reducing the cost of bandwidth and exaltating the service quantity of communication. The focus of the key factor is the construction of the basal network. Transport network is the foundation network, so the construction of the 3G transport network play an important role in the whole network. How to go to the relation between the traditional service and the burgeoning data service, the relation between the existing network and the Large-scale 3G network, comprehensive technique cost and customer need, which to choose the technique and the project, all of them is the problem which we must consider.
 This article take the third generation mobile telecommunication (3G) as the topic, carrying on the analysis and discussing. First,it introduced the development of 3G and the good and challenging environment。Go deep into the technique foundation of analyze its most and the key technique The full text compares to carried on the overall description and analysis to the background that the 3G network construction and the main technique use systematically.
Key words: CDMA,WCDMA,TD-CDMA,Connect the dint cut over
