TD-SCDMA路测系统的网络优化分析与研究
|
摘要
随着移动通信业的逐步发展,移动通信市场的竞争日益加剧,网络质量的好坏已成为网络运营商占领移动通信市场、把握成败的关键。TD-SCDMA作为我国第一个具有自主知识产权的第三代移动通信技术主流标准,必将成为我国未来第三代移动通信网络的主要网络体系。因此,对于未来的TD-SCDMA网络运营商而言,如何经济有效地建设一个TD-SCDMA网络,如何开展网络优化工作,保证网络的高性价比是运营商特别关心的问题。可见,TD-SCDMA网络规划和优化工作越来越重要。
作为网络优化工具的典型代表,路测是网络建设和优化中的一项基本而且重要的手段。以本人参与的TD-SCDMA的无线网络优化路测项目为背景,本文在TD-SCDMA系统基础理论之上,从网络优化路测技术出发,设计与实现了AirWisdom路测系统中的诊断分析模块,并运用此系统来分析网络优化问题,指导网络优化工作。本文的主要研究是基于路测模式下的网络优化分析。
在简要介绍了第三代移动通信系统的概况和分析了TD-SCDMA系统关键技术特征后,本文分析了TD-SCDMA网络优化的重要性、必要性以及当前网络优化工作所面临的一些挑战,提出了在TD-SCDMA网络规划初期,通过路测方法来进行网络优化。然后,文章分析了路测模式中网络优化的方法、内容、流程、一般性原则和测试过程中一些常见性网络问题。为了及时地发现和有效地解决当前TD-SCDMA网络优化中的问题,本文设计并实现了AirWisdom路测系统诊断分析中的导频污染、越区覆盖、邻区优化模块。在诊断分析实现过程中,文章详细地分析了诊断分析的流程、设计方案和实现方法。随后,透过具体的网络优化案例可以分析出,本文设计的系统诊断分析功能能够发现网络中的导频污染、越区覆盖、掉话、邻区漏配等问题,能够分析问题发生的原因以及由此对网络造成的影响,并且针对这些问题进行优化,给出问题解决方案。从问题的处理结果也可以看出,文中提出的解决方案针对性强,能够指导网络优化工程师迅速地定位网络问题和解决网络问题,提高网络质量。
With the development of the industry of mobile communications and the ever-increasing competition, the quality of the network is the key to the success of network operators. TD-SCDMA is one of the criteria of the third generation of mobile communication technology about which we have our own intellectual property rights. For the future TD-SCDMA network operators, their major concern is how to build a TD-SCDMA network efficiently and how to optimize the network in order to ensure high performance at low cost. Consequently, the network planning and optimization of TD-SCDMA becomes more and more important.
As the typical example of the tools of network optimization, drive test is one fundamental and very important method in network planning and optimization. Based on the theory of TD-SCDMA system and the technology of drive test, this thesis designs and realizes the model of diagnosis analysis in AirWisdom drive test system, which helps to analyze the problems and guides the specific examples of network optimization. The thesis mainly focuses on the research of network optimization in drive test model.
After the brief introduction of the third generation of mobile communication system and the key characteristics of TD-SCDMA system, the thesis points out the importance and necessity of TD-SCDMA network optimization and the challenges we are facing now and puts forward that drive test could be used in network optimization at the beginning stage of TD-SCDMA planning. Then the thesis analyzes the methods, contents, procedures and general principles of drive test in network optimization and points out some common problems in drive test. To solve the current problems in TD-SCDMA network optimization efficiently, the thesis designs and realizes the models of pilot pollution, over coverage and neighbor cell optimization for diagnosis analysis in AirWisdom drive test system. The thesis elaborates the procedures, designing proposals and realizing methods of the diagnosis analysis. Subsequently from the specific case study of network optimization, it can be seen that the system designed in this thesis could detect the problems such as pilot pollution, over coverage, drop call and neighbor cell missing, analyze the causes and their effects on the network, and provide solutions to these problems. From the final results we can see that these solutions can guide the network optimization engineer to locate and solve network problems very quickly and help to improve the quality of the network.
