【摘要】 在政府和运营商的大力支持下,TD-SCDMA的网络建设工作正在如火如荼地展开。随着网络建设进度的发展,网络质量的测试成为工作的重点。在网络大规模建设完成之后,需要进行全网的测试评估工作,了解网络运行状态,在保持网络质量的前提下,进一步进行优化。无线环境评估作为网络评估非常重要的一个方面,其主要作用是对移动通信网络在当前区域的网络覆盖质量进行评估,让优化人员对当前区域的网络情况有全面的了解。路测软件的作用是通过采集分析海量的测试数据,帮助优化人员更好地掌握无线网络的运营现状。对于作为网络服务基础的无线环境,路测软件必须给予足够的重视,无线环境评估模块作为路测软件中不可或缺的功能模块,正是承担了对网络无线环境进行分析评估的任务。因此,设计并开发出具有无线环境质量评估功能的网络路测软件是非常有价值的。本文以"TD-SCDMA路测系统中无线环境评估模块的设计与实现’为课题,做了以下工作：1)根据TD-SCDMA网络结构、无线环境的特点、网络评估和网络优化要求,给出了无线环境评估的模型,突出了评估模型的三要素,分别为覆盖评估、干扰评估和导频污染评估。2)根据建立的无线环境评估模型,提出了覆盖、干扰和导频污染评估各自的评估指标和评估算法。3)实现了无线环境评估模块的基本功能,包括从数据库获取数据,分析数据,显示分析结果并保存为报表。4)在基本功能完成的基础上,添加了手动设置参数门限值的功能,可随时根据实际情况调整分析门限。5)对评估模块的功能进行了大量实际测试,修正评估算法并对未来的发展进行了展望。更多还原

【Abstract】 By the support of the China government and China Mobile, the network construction is in full swing. With the progress of the development of network construction, the testing of network quality has become the focus of work.After the completion of large-scale construction of the wireless network, It is need to test and evaluation the whole wireless network to get the ststus of the network.It is necessary not only just maintaining the network quality, but also to optimizate the perfomace of network.Radio Environmental assessment as a very important aspect of network evaluation, It is use to evaluate the radio network’s coverage and service quality in the current region. Radio Environmental assessment can help the engineer to get the current situation of the network and optimize it better.wireless mobile network testing software help people learn and master the operational status of the wireless network through collecting and analyzing massive test data. The testing software must pay attention to the assessment function in this field, while environmental quality evaluation module, the important function module, is responsible for the assignment of analyzing and assessing the wireless environment. Thus, the design and development of wireless mobile network testing software with wireless environment quality assessment function has a very important value.With the "Design and Implementation of the Radio Environment Evaluate Module of TD-SCDMA" as research focus, this paper mainly complete the following work: 1) Deeply study of TD-SCDMA network structure and network optimization. Based on those knowledge, design the radio environmental assessment model, identify the three elements of the assessment model: Coverage, Interference, and Pilot Pollution.2) Analysis the function requirement of wireless environment evaluate module, especially the evaluation algorithm, contains the coverage, interference and pilot pollution.3) Design and implement the basic function of wirless environmental assessments, including access to data from the database, analyze data, display results and save the reports.4) Design and implement the threshold manually set function, that the parameters of the threshold can be adjusted according to actual situation at anytime.5) Doing a large number testing of the module, modified assessment algorithm development and doing the future prospect.更多还原
