摘要
第三代移动通信系统虽然仍处于预商用阶段 ,但许多公司和组织早已对三代以后的移动通信系统及其关键技术开始前瞻性的预研工作了。本文首先分析了未来移动通信系统的发展趋势 ,认为未来的移动通信系统将具有更高的传输速率、更高的频谱利用率 ,同时支持与基于IP的其它数据网络的互联互通 ;最后 。
Although 3G mobile systems are still in the phase of pre commercialized, many famous companies and international organizations have started the far sighted research of beyond 3G or 4G mobile communication systems earlier. This paper first analyzes the tendency of future mobile communication systems and the authors believe the future mobile communication systems should have the characteristics of high data rate, high spectral efficiency besides having the ability of interoperation and interconnection with other IP based data networks. Finally this paper describes the probably adopted network structures and wireless transportation techniques in the future mobile communication systems.
