AbstractFixed-MobileConvergence(FMC)aimstoenableusertogetthesameserviceexperiencethroughdifferentaccessnetworks.Inordertoachievetheconvergenceoffixedandmobilenetworks, the solutionssuch as UMA,Femtocell andIMS are proposed.But, theFMC promoted by telecomoperatorshasitsnaturaldisadvantages,thatis,theusercanonlyhaveafreechoiceamong thenetworkswhichbelongtotheoperatorhe/shehassubscribedto.Thoughtherearelotsof networksintheuser’sarea,theusercannotchoosethem.Althoughusercanchoosetobuytheservicesfrommultipleoperators,itwillincreasethecostandleadtheuserintotrouble,suchas multipleuseridentities,multiplenetworkbillsandsoon.InordertoaddresstheshortcomingsofthecurrentFMC,acustomer-cenricbasedFMCmodelisproposed.Thismodeliscustomer-centricandseparatestheAAAoperationfromthenetworkoperator,sothattheusercanchoosethenetworkfreely.ThentheAAAofthenewmodelhasalargedifferencewiththeAAAoftraditionalconvergenceandthisproducesnewAAAsignalingflow.Thesignallinginterfacesare definedforthe model.Thenbasedontheextension ofDiameter protocol,adetaileddescriptionofthenewsignalingflowisgiven.Afterthat,basedontheopensourcefreeDiameterprotocolstack,thenewsignalingflowsareimplemented.Atlast,thepaperconcludeswithasummaryoftheworkandresearch,andlooksaheadintothefutureresearch.Keywords:fixedmobileconvergence,AAA,Diameterprotocol,freeDiameter目录第一章绪论11.1研究背景11.2研究目标和研究内容21.3研究思路与创新点21.4论文结构安排3第二章文献综述52.1引言54.3.3接口协议扩展314.4基础信令流程344.4.1阶段1：认证和授权344.4.2阶段2：接入阶段364.4.3阶段3：终止阶段384.4.4 重新认证和重新授权414.4.5 为用户的账户充值434.4.6故障恢复机制464.5切换相关流程494.5.1用户触发的切换504.5.2 业务提供商触发的切换514.6多个接入网络提供商承载的固定移动融合业务524.7本章小结55第五章I-AAA信令流程实现575.1引言575.2协议消息575.2.1 ‘A’接口上的消息575.2.2 ‘B’接口上的消息595.2.3 ‘C’接口上的消息60freeDiameter开源协议栈介绍61freeDiameter开源协议栈的扩展615.5测试平台的搭建665.5.1 硬件平台665.5.2 软件平台665.5.3 编译安装665.5.4 配置运行675.5.5部署架构图685.6运行结果及其分析685.6.1 用户与接入网络提供商之间的认证和授权685.6.2 同时使用多个接入网络提供商的信令流程705.7本章小结71第六章总结与展望726.1总结726.2展望73参考文献75附录1 攻读硕士学位期间撰写的论文77附录2 攻读硕士学位期间申请的专利78附录3 攻读硕士学位期间参加的科研项目79致谢80第一章绪论1.1研究背景近年来，随着互联网的兴起，网络融合已是大势所趋。为了适应这种趋势
