基于IMS的网络融合分析研究

四川师范大学成都学院本科毕业设计基于IMS的交换网络融合分析研究学生姓名吴修利学号2009101096所在系通信工程系专业名称通信工程班级2009级1班指导教师倪磊四川师范大学成都学院二○一三年五月四川师范大学成都学院本科毕业设计I基于IMS的交换网络融合分析研究学生：吴修利指导教师：倪磊内容摘要：随着通信技术的发展，融合是通信界网络发展的必然走向，其覆盖范围非常广，包括运营商、用户、网络技术、设备与解决方案等各个方面。从用户角度，通过无线有线的接入方式和简单易行的通信方式可以享受个性化服务；从运营商角度，融合可以向用户提供全面的业务服务，并能提高在市场所占有的利润和份额。鉴于IMS（IP多媒体子系统）具有采用SIP协议进行与接入无关、呼叫控制和能够灵活提供多种业务的特点，本文在IMS体系结构的基础上，提出网络融合的参考架构，并对IMS实现固定和移动网络融合的可行性进行详细分析，分析结果表明固网PSTN和移动网络在IMS在能实现互通。关键词：IMS交换网络网络融合四川师范大学成都学院本科毕业设计IIAnalysisofFusionSwichedNetworkBasedonIMSAbstract:Withthedevelopmentofcommunicationtechnology,integrationisaninevitabletrendofthefuturedevelopmentofthenetwork.Itscoverageisverywide,includingallaspectsofthenetworktechnology,users,operators,equipmentandsolutions.Totheuser'spointofview,theycanenjoypersonalizedservicefromcommunicationmodewhichusesthesimpleway.Totheoperator’spointofview,integrationcanprovideuserswithfull-serviceoperation.Italsocanofferthemincreasingmarketshareandprofits.BecauseIMS(IPMultimediaSubsystem)hasthecharacterswhichincludeSIPprotocolforcallcontrol,havingnothingtodowiththeaccessandtheflexibilitytoofferavarietyofbusiness.ThisarticleisbasedonIMSarchitectureandanalysisthefusionwhetheritisfeasible.Weobtainedaresultsthatthefixed-linePSTNandmobilenetworkstoachieveinteroperabilityinIMS.Keywords:IMSSwitchedNetworkFusion四川师范大学成都学院本科毕业设计III目录前言............................................................................................................................................11移动交换网络架构..............................................................................................................21.1移动台子系统（MS）.................................................................................................31.1.1移动终端(MT)..................................................................................................31.1.2用户识别卡（SIM）........................................................................................31.2基站子系统（BSS）...................................................................................................31.2.1基站收发台（BTS，BaseTransceiverStation）....................................31.2.2基站控制器（BSC，BaseStationController）......................................31.3网络子系统（NSS）...................................................................................................41.3.1移动交换中心（MSC）.....................................................................................41.3.2拜访位置寄存器（VLR）.................................................................................41.3.3归属地位置寄存器（HLR）.............................................................................41.3.4鉴权中心（AUC）.............................................................................................41.3.5设备识别寄存器（EIR）.................................................................................52IMS........................................................................................................................................52.1IMS的定义..................................................................................................................52.2IMS的网络架构..........................................................................................................52.2.1业务应用层......................................................................................................62.2.2控制层............................................................................................................72.2.3传送层..............................................................................................................82.3IMS的优点..................................................................................................................83基于IMS的固定与移动网络融合方案.............................................................................83.1网络融合的需求分析.................................................................................................83.2基于IMS的下一代融合网络架构.............................................................................93.2.1接入层............................................................................................................103.2.2传输层............................................................................................................103.2.3会话控制层....................................................................................................103.2.4应用层............................................................................................................113.3融合分析...................................................................................................................123.3.1融合的方案分析............................................................................................12四川师范大学成都学院本科毕业设计IV3.3.3融合的接入安全分析....................................................................................154结束语................................................................................................................................17参考文献:....................................................................................................
