摘 要
TD-SCDMA第三代[4]移动通信系统是我国无线通信标准组织CWTS提出的并得到ITU批准的三大主流标准之一。随着第三代移动通信的发展,我们将面临如下的问题:TD-SCDMA网络结构复杂,不但通信协议繁多,接口复杂,同时还与2G网共存;复杂的3G网络数据业务。TD-SCDMA网络将面临着不断更新的新业务挑战;用户对TD-SCDMA期望值的提高,使得TD网络QoS保障面临前所未有的挑战;TD-SCDMA网络大规模建网的同时,互联互通问题在所难免。目前针对TD-SCDMA网络的现有维护手段主要还是依赖于测试仪表,功能上还有很大欠缺,一般都是等到出现问题才进行测试,维护处于被动,主要用于发生故障时的排障。对于全面了解网络运行数据,掌握网络运行状态的要求,需要一个能够提供长期相关数据的维护平台,因此,TD-SCDMA集中监测系统应运而生。
TD-SCDMA网络集中监测系统将在系统的实验研发、网络建设与优化,以及运行维护中,起到极其重要的作用。其主要是利用网络监测仪监测其设备的状态、或者利用网络集中监测系统的功能来及时的检测其设备的互连互通问题。集中监测系统具有集中性、实时性、全天候三大特点,变被动为主动,它不影响网络的运行,能够及时发现网络故障并预警,同时可以保存数据并复原故障场景,使移动用户能够实时监视、追踪和测试当前网络状况,从而使网络维护人员掌握和分析网络和业务运行情况,是中国移动运营商维护和优化TD-SCDMA网络,实现“业务与服务双领先”战略最重要的支撑系统。
Iub接口作为TD-SCDMA网络一个重要接口,该模块信令监测技术的研究和开发在TD-SCDMA集中监测系统开发中不可或缺。论文以TD-SCDMA集中监测系统为研究背景,首先概要介绍了TD-SCDMA的技术特点和网络结构,并深入研究了Iub接口在网络中的功能、协议栈结构,接着分析了TD-SCDMA集中监测系统的结构、功能。在介绍监测系统总体结构和软件构架的基础上,详细分析了Iub接口信令监测的整体方案及接口的解码监测,并对监测方案中的解码模块做了详细设计和实现,结合3GPP协议对仿真结果进行了详细说明,表明该文提出的Iub接口FP层信令解码设计方案准确、可靠、达到了预期的目标。最后,对论文的研究和开发工作进行了全面的总结,并对课题的进一步的研究进行了展望。

Abstract
TD-SCDMA communication system is proposed by Chinese Wireless Telecommunication Standard(CWTS) and is approved by the ITU as one of the three main standard. With the development of third generation mobile communications, we will face the following problems: TD-SCDMA network structure is too complex with numerous communication protocols, interfaces, and also co-exist with the 2G network; what’s more,the data services of the 3G network is too complex. TD-SCDMA network will face new and evolving business challenges; user ’s expectations of improving the network making TD network’s QoS face unprecedented challenges; the Interconnection will also be a problem when build a large-scale of TD-SCDMA network.At present, the available means for maintaining TD-SCDMA network mainly depends on testing instruments, and there are defficiencies in function. Usually, people only do testing when the problems happens, and maintenance is passive, which is mainly used to eliminate barriers when it get failure. In order to comprehensively understand the network operations data, master the requirements of the network operational status, we need to provide a long-term data maintenance platform. Therefore, TD-SCDMA centralized monitoring system came into being.
TD-SCDMA Centralized monitoring system plays a vital role on network construction, research, network optimization and network maintenance. It mainly use the network monitoring equipment to monitor the status of the equipments, or use the function of Centralized monitoring system to detect the interconnection problems of equipments in time.Centralized monitoring system has three main features: centrality, real-time and all-weather, which could change from passiveness to activeness and does not affect the operation of the network. It has the ability to detect network failures and makes advanced warning. Furthermore it could save the data and recover failure scene, and enable mobile users to real-time monitor, track and test the current network, which would make the network maintenance personnel master and analyze the running conditions of the network and business. TD-SCDMA centralized monitoring system is the most important supporting system for Chinese mobile operators to maintain and optimizes the TD-SCDMA network, and achieves the strategy of “leading both in business and service”.
As a very important interface in TD-SCDMA network, the researches and development of signaling monitoring technology, which are done to the Iub interafce, is indispensable to TD-SCDMA centralized monitoring system. This thesis is set in the researches of TD-SCDMA centralized monitoring system. Firstly, paper has introduced the technical characteristics and network architecture of TD-SCDMA, and also has done intensive study in the functions、structure of protocol stack。Then we analyzed the structure and functionality of TD-SCDMA Centralized mornitoring system. After introduced the overall structure of monitoring system and the architecture of software, the entire scenario of Iub interface signaling monitoring and the monitoring of interface decoding was detailedly analyzed. And exhibited and analyzed the decoding module in monitoring scenario, proved the design scenario of signaling decoding of FP layer on Iub interface is accurate and reliable, achieved the expected purpose. At last, I summarized the research and development on this thesis and looked ahead to the further research of this task.
