WCDMA无线网络规划设计
摘要
在我国,目前已经拥有了全球最大的移动通信网和最大的移动用户数,移动用户的数量已经超过4亿,而且这个数字还将快速增长。现有的第二代移动通信系统无论是在频谱资源,还是在所能提供的业务方面,都已经不能满足移动通信用户的需求。
本论文讨论的WCDMA是一项全球应用最广、最成熟的3G技术,论文从WCDMA的应用现状出发,首先介绍了3G标准的提出及其商用情况,并简要地阐述了研究WCDMA技术的意义。然后介绍了无线网络系统,重点分析了无线网络系统及3G网络的规划与设计方法。接着重点分析了WCDMA网络的规划的流程和注意事项以及需要重点考虑的因素,并阐述了WCDMA核心网络的规划与设计方法。
最后本文在对3G的市场需求进行定性预测的基础上,结合兰州市的具体情况,分析了WCDMA网络规划时所需考虑的基本原则,提出在兰州市构建WCDMA核心网络的预规划方案。

ABSTRACT
Mobile subscriber's rate of rise goes far beyond the fixed telephone user's rate of rise in our country and even the world. At present already we had the global biggest work in our country and the biggest mobile subscriber number, and mobile subscriber's quantity already approached four hundred million, moreover, this number also is growing fast. The existing second-generation munication system regardless of is in the frequency spectrum resources or in the service aspect which can provide, all already could not satisfy the munication service development demanded.
Here what the paper discusses is the technology of WCDMA which is the most widely used and most mature of the third generation munication ,papers from the applications status of WCDMA, introduced the proposal and the 3G mercial conditions, and briefly explained the significance of WCDMA technology. Then introduced the work system,and emphasis analyzed the planning and design methods of the work System and work. Then analyzed the work planning process and key considerations and the need to take into account factors, And elaborated the planning and design methods of the WCDMA work.
And then,based on the qualitative forecast of 3G market and service and Lanzhou’s actual situation,then analysis the basic principles which should be considered in the WCDMA’work planning, and proposed the pre-planning of WCDMA work in Lanzhou City.
