南京邮电大学硕上研究生学位论文摘要摘要随着移动通信技术的迅猛发展,传统的以话音和低速数据业务为主的第二代地面移动通信系统己逐渐不能满足人们的要求,3G以其先进的技术特征和丰富多彩的业务类型吸引了广大用户的关注。第三代移动通信系统具有更高的容量、更高的速率等诸多优势, 但同时也给无线网络规划带来新的问题。WCDMA系统无线网络的规划工作是WCDMA系统走向商用的关键工作,它直接影响到设备性能的发挥,网络的容量和运行质量,同时也直接影响到网络的建设成本。本文以湖北省恩施市为例,探讨WCDMA网络中纯语音业务、语音及数据混合业务的无线网络覆盖规划方法及流程,做一些容量、覆盖及质量规划,根据规划需求和网络特性,设定工程参数和无线资源参数,并在满足一定信号覆盖、系统容量和业务质量要求的前提下,用最合理的方法使网络的工程成本最低。 WCDMA是一个软容量和混合业务系统,在进行无线网络规划的时候,需要充分考虑容量、覆盖和系统干扰的相互影响。该无线网络规划包括预规划和详细规划,其中预规划包括链路预算、容量规划、站数估算等:详细规划包括现场调研、站址选择、传播模式调校及规划、软件仿真等。该无线网络规划是根据本人的工程实际经验及WCDMA的理论相结合,在中国联通发展WCDMA之际,参与工程前期规划,与设计院、设备厂家充分沟通做出湖北省恩施市的 WCDMA无线网络规划。本论文的一些结论和方法对正在进行的WCDMA网络建设有一定的实际指导意义。关键词:WCDMA,无线网络规划,容量,覆盖南京邮电大学硕士研究生学位论文 ABSTRACT ABSTRACT With the rapid development of the mobi munication technology,The traditional second munication system has not been able to meet people’S request gradually because of the primary services of the voice and the low—speed ,featuring advanced technology and varied business types, begins to attract more and more attention from the excellences of 3G mobile munication system include high capacity and high excellences bring on difficulty to plan work at the same planning of work of WCDMA system iS critical work for WCDMA system to Planning directly influences the performance of the equipments,work’S capacity and the operation quality,as well as the cost of work’S cOnstruct ion. ThiS thesiS which shows the example ofENSHI inHUBEI,discusses the methods work planning for the speech and data services plans the capability,coverage and quality and sets the radio resource parameters according to the makes work cost the least based on fulfilling the requirements of certain signal coverage,system capabi 1ity and service quality. WCDMA is a soft capacity and the mix operational channel, carrying on the work planning, needs to consider fully the capacity,the coverage and the system disturbance mutual work planning includes the pre—pla
