【摘要】 无线网络优化是一个改善全网质量、确保网络资源有效利用的过程,移动通信网络是一个动态的网络。由于话务密度分布不均匀、频率资源紧张、网络配置未达最佳并且长期处于不断变化之中等因素,使得现有网络的服务质量不尽如人意,巨额的投资并没有得到最高的收益,所有这些都要求运营商应不断地准备对网络进行调整,以便优化资源配置,合理地调整网络的参数,使网络达到最佳的运行状态,这就是移动通信网络优化要达到的目标。 本文分析了基站扩容、参数修改等网络调整办法的局限性。并统计分析出在各个时间段上,不同类型的小区有不同的资源需求,而目前无线网络容量的设计思路是按照小区的最忙时来设计容量,这不可避免的造成了一定的资源浪费,从目前的话务增长趋势来分析,这种设计也很难完全满足到所有的话务突发情况。从而提出动态调配调整移动蜂窝网的载频资源,提高网络利用率具有积极的意义。 动态调配调整移动蜂窝网的载频资源,还涉及提高调整的反应速度的问题。文中从介绍了无线资源动态配置及优化系统的工作原理和技术性能,引出系统能实现的功能。并探讨该系统在不同的使用环境中的运用方式,和预先要解决的容量分析和上下行平衡等问题,按照理论依据得出考虑相关问题的必要性和可行性。 论文以贵阳移动使用无线资源动态配置及优化系统的实例,验证了该系统能动态配置无线资源,提高资源利用率,从而有效吸收话务量。同时该系统的引入对无线网络指标的影响较小。论文还把贵阳移动在使用该系统时遇到的问题逐一分析,从技术层面深究问题出现的原因,从理论联系实际的角度论证解决问题的可行性技术方案。 全文结合贵阳移动公司在使用无线资源动态配置和优化系统的过程中发现的问题,分析问题出现的原因,把处理问题用到的各种技术手段,调整方案归纳整理,提炼出该系统所适宜的应用环境和建设实施的技术规范。文中以提高载频资源利用率同样的思路,首次提出频率资源同样存在时间域上的利用率问题。更多还原

【Abstract】 Wireless optimization is a process of improving the network quality and efficiently using the network source. The wireless network is dynamic. Due to the traffic unbalance, shortage of the frequency, the network configuration can not and never be achieved to the best and it always change all the time, so the service is not as good as our expectation. We invest huge money but the return is not satisfied. All of this asks carriers keeping ready to turn the network to optimize the network by adjusting the network parameter reasonably to make the network working properly and optimally. This is the goal of the Wireless optimization.In the article I analyze the disadvantage of some normal optimization ways, such as the upgrade of the BTS and adjusting the parameter and so on, and gets the conclusion that there are different network demands at different time and type of the Cell. Normally, the way to design the network is based on the busiest time traffic model but it could unavoidably make the waste of the source because most of it is the non-busiest time and from the trend of increasing traffic it is found that it is also difficult to satisfy the suddenhigh traffic situation, for example meeting or sports game ...... So the dynamicconfiguration of the network is more attractive and important.The action rate is involved in the dynamic configuration. The article describes the principle of the wireless optimization and dynamic configuration and get the conclusion that what can be done by now. It also discusses the dynamic configuration’s different operation model under different situation and why and how to analyze the capability, unlink and downlink balance issue in advance.It proves in the article that the dynamic configuration system is useful to configure the RF resource dynamically, improve the utilize rate and absorb the traffic efficiently in using the system by Guiyang Mobile. On the other hand, the system has very less distortion for the network index. It also analyzes every issue, which was met in the Guiyang, presents why it was occurred technically and gives a reasonable resolution.It concludes the suitable environment of application and technical standard for the dynamic configuration system based on using this system, finding out all kind of issue during the time when Guiyang Mobile was using it, analyzing the reason why those issues are occurred, and concluding all kinds of technical way to resolve them as well. The paper figured out the new ideals at the first time that utilization of RF resource has closerelationship with the time.更多还原
