[论文摘要]随着信息时代的到来，计算机技术的蓬勃发展，以及人们对移动通信的需求迅速增加，移动通信技术的更新换代的声音越来越大。人们不禁会问，移动通信技术的未来是什么？而3G正是在这种时代背景下诞生的。3G是英文3rd Generation 的缩写，指第三代移动通信技术。相对第一代模拟制式手机（1G）和第二代GSM、TDMA 等数字手机（2G），第三代移动通信一般地讲，是指将无线通信与国际互联网等多媒体通信结合的新一代移动通信系统。它能够处理图像、音乐、视频流等多种媒体形式，提供包括网页浏览、电话会议、电子商务等多种信息服务。
本文从移动通信发展简史、3G系统的功能特点、世界三大主流3G标准的比较分析等几个方面着手，详细介绍第三代移动通信技术的技术特点和中国3G的发展现状及未来。

[Abstract] Along with the information age arrival, the mobile communication demand is rapid increase since the development of the computer science. The mobile communication technology renewal is imminent. What is the future of the mobile communication technology? 3G. 3G is the third generation for short. It means the third generation mobile communication technology. The cellular concept was introduced in the 1G technology which made the large scale mobile wireless communication possible. Digital communication has replaced the analogy technology in the 2G which significantly improved the wireless communication quality. 3G stand is the third generation of wireless communication technologies, which can process the image, music, the video frequency flows and so on many kinds of media form, provides including the homepage browsing, the teleconference, electronic commerce and so on the multiple message service. Therefore, the difficulty brought by the method of labeling an image manually becomes significant.
This article will introduce the mobile communication development brief history, the 3G system function characteristic and the comparison and analysis of the three main 3G standard. And then it detailed introduce the third generation mobile communication technology technical characteristic and 3G development present situation and future in China.
