摘要
综述了未来移动通信系统的发展趋势及其在技术上所面临的挑战 ,在分析国内外移动通信发展现状的基础上 ,指出了我国移动通信领域的发展战略。未来移动通信系统更高量级数据速率的要求、数据速率的大动态变化范围、IP地址的个人化和有限的频谱资源等诸多方面的特点 ,要求系统有更加先进的网络、更加灵活高效的空中接口和移动终端等。世界各国已经开始了 4G的研制工作。我国应该抓住时机 ,及时开始 4G关键技术的研究 ,在不断发展科研力量和输出知识产权的基础上 ,要充分利用各种有利因素 ,扩大我国在移动通信领域的国际影响 。
The developing trends and technical challenge of future mobile communications are summarized in this paper, and development strategies of China's mobile communications are suggested based on the analysis of developing status of world mobile communications. The characteristics of future mobile communications, such as requirement of data service with higher speed, huge variety range of data speed, personalization of IP address and limited wireless spectrum resource, put forward requirements of more advanced network, more flexible air interface and mobile terminals. The R & D of 4G has begun in all over the world. In order to develop China's mobile communications, China should grasps the opportunity to begin the R & G of 4G key technologies in time, and not only develops the force of R & D and outputs IPR, but also spreads the impacts in the world communication field through all sorts of beneficial factors.
