【摘要】：随着移动通信业务的高速发展,越来越多的普通人享受着移动通信发展带来的便捷。目前我国的移动通信网络正处在2G网络、3G网络、WLAN网络以及4G试验网络共存阶段。从网络覆盖范围、用户数量以及业务量等三方面分析,当前应用最广泛的仍然是2G网络,而WLAN网络、3G网络正处在高速发展阶段,正在为公众提供优质的数据业务服务。但随着网络规模以及网络语音、数据业务量的高速发展,网络中正不断暴露出各种各样的新问题,这些问题困扰着网络的健康发展,在这些问题中最为突出的是:如何合理配置无线资源问题、提升无线网络性能的优化问题、WLAN高速发展期下的网络精确规划问题等。针对以上网络发展中最为凸显的三类问题,作者结合自身工作实际,展开了深入研究,从网络资源配置原则、数据分析规则、优化实例等3个方面开展了系统研究,通过研究实践,提出了一套系统解决GPRS网络GBL/GSL/PCU/PDCH等无线资源的配置优化方法,解决了GPRS系统资源优化问题。在无线资源优化方面,为了充分发挥现网资源的利用效率,本文对现网大量的统计样本点进行了深入分析,从整网级、小区级以及分场景覆盖三方面进行了探讨,找出了随着无线利用率增长,网络性能出现陡峭恶化的区域,确定为无线利用率优化的控制上限,用于指导实际生产。本文在研究提升无线网络性能方面,聚焦网络热点问题,重点剖析了影响网络接入性能的PCH寻呼优化以及影响网络稳定性能的隐性故障问题,从理论分析入手,制定算法规则,结合现网实际,提出了一套针对无线网络性能提升的优化方法,并通过现场优化实践,验证了优化方法正确有效。本文对2G/3G/WLAN网络共存阶段的协同优化问题进行了尝试性探讨,重点针对WLAN站点精确部署,协同分流2G/3G业务热点进行了研究。作者通过研究提出了一套基于PS域信令监测系统分析,精确定位WLAN业务热点的分析方法,解决了当前WLAN站点规划不准确,易出现设备热装冷用的突出问题。在提出WLAN站点精确规划的基础上,作者开发了WLAN精确规划的自动分析工具,支撑了WLAN站点的高效、精确规划,达到了WLAN建设与GSM、TD-SCDMA网络协同发展目的。
[Abstract]:With the rapid development of mobile communication services, more and more ordinary people enjoy the convenience of the development of mobile communication. At present, the mobile communication network in China is in the stage of coexistence of 2G network, 3G network, WLAN network and 4G test network. From three aspects of network coverage, the number of users and the volume of business, the current application is the most widely used. It is still the 2G network, while the WLAN network and 3G network are in the high speed development stage and are providing high quality data service for the public. However, with the rapid development of the network scale and the network voice, the high speed of the data business, the network is constantly exposing a variety of new problems. These problems have plagued the healthy development of the network. The most prominent problem is how to rationally configure the problem of wireless resources, improve the optimization of wireless network performance, the problem of network precision planning under the high speed development period of WLAN. In view of the three most prominent problems in the development of the above network, the author has carried out a thorough study on the basis of the principle of network resource allocation and data. The system research is carried out in 3 aspects, such as the rules of analysis and the optimization of example. Through the research and practice, a set of methods to optimize the configuration of the wireless resources such as the GPRS network GBL/GSL/PCU/PDCH is put forward to solve the problem of the optimization of the resources of the GPRS system. The statistical sample points are analyzed in depth. From the three aspects of the whole network level, the community level and the sub scene coverage, we find out the area with the increase of wireless utilization rate and the steep deterioration of the network performance. It is determined that the control upper limit of the wireless utilization rate optimization is used to guide actual production. This paper is to improve the performance of wireless network. Focusing on the hot issues of network, this paper focuses on the analysis of the PCH paging optimization which affects network access performance and the hidden faults that affect the network stability. From the theoretical analysis, the algorithm rules are formulated, and a set of optimization methods for the performance promotion of wireless network is proposed in combination with the reality of the current network. The optimization method is correct and effective. This paper attempts to discuss the cooperative optimization problem of 2G/3G/WLAN network coexistence stage, focusing on the precise deployment of the WLAN site and coordinating the hot spot of 2G/3G service. The author has put forward a set of analysis parties based on the PS domain signaling monitoring system analysis to accurately locate the hot spot of the WLAN service. The method, which solves the problem of the inaccurate planning of the current WLAN site, is easy to appear in the hot installation of the equipment. On the basis of the precise planning of the WLAN site, the author develops an automatic analysis tool for the precise planning of WLAN, which supports the efficient and accurate planning of the WLAN site, and achieves the purpose of coordinating the development of WLAN with GSM and TD-SCDMA network.
