GSM网络优化方法研究毕业论文_精品.doc

摘 要 网络优化是一门正在发展中的技术,技术难度大,涉及的技术领域广泛,技术复杂度也在不断提高,对网络优化的技术要求也越来越高. 移动网络本身的演进和发展也为网络优化的不断带来新的课题。 本文对GSM网络优化方法进行了研究，GSM网络优化的方法很多，文中对GSM系统、网络优化的目标和流程进行简单的介绍，主要研究了室内覆盖的优化、天线系统的优化、掉话的分析解决方法以及对大学园区网络优化结果进行了分析。具体内容如下： 室内覆盖问题包括对室内移动通信话音质量、网络质量、系统容量的改善问题。改善室内覆盖，有两种基本方法：一种是加大室外信号解决室内的覆盖；另一种是采用室内信号分布系统方式来结决室内覆盖。 天线系统的优化，天线的性能质量直接影响移动通信网络的覆盖和服务质量，调整天线的方向参数、增益、输入阻抗、驻波比和极化方式等都能对移动通信网起到优化的作用。 切换导致的掉话；干扰导致的掉话；天馈线原因产生掉话的情况进行了分析和解决方法。 大学园区高话务的简要分析和解决方案。 关键词： GSM ； 频率复用通信质量网络优化  Abstract The network optimization is developing the technology, the technical difficulty in a big way, involves area of technology widespread, technical complex also unceasingly is enhancing, optimizes the specification to the network more and more to be also high The motion network itself evolution and the development also optimizes for the network unceasingly brings the new task. This article conducted the research to the GSM network optimization method, the method which the GSM network optimized have been very many, in the article the goal and the flow which to the GSM system, the network optimized carries on the simple introduction, mainly studied optimized, the antenna system optimization which in the room covered, has fallen the speech the analysis solution as well as has carried on the analysis to the big academy area network optimization result. Concrete content as follows: In the room covers the question including to the room in the mobile communication voice quality, the network quality, the system capacity improvement question. In the improvement room covers, some two essential methods: Outside one kind enlarges in the signal solution room cover; another kind is uses in the room the signal distribution system way to tie definitely in the room to cover. The antenna system optimization, the antenna performance quality direct influence mobile communication network cover and the grade of service, adjust the antenna the direction variable, the gain, the input impedance, the standing-wave ratio and the pol
