('ATM是特殊的面向连接的协议，不提供任何确认机制。虽然ATM提供了从AAL0到AAL5多种类型的适配层协议，但没有一种AAL支持简单的点到点的可靠传输，于是在AAL层定义了SSCOP实现此功能，SSCOP只用于控制信令，不用做数据传输。为了有效可靠地承载信令，在传输网络层使用分层结构，从下到上分别是SAAL（AAL5交换）、MTP3B和SCCP。再往上就是应用层的如NBAP（NodeB应用部分）、RANAP（无线接入网络应用部分）等。SAAL作为底层承载，采用AAL5交换，向MTP3B提供可靠的面向连接的数据传输，在OSI的7层体系中，可对应理解为数据链路层；MTP3B用于ATM网络中传送信令（MTP3用在TDM信令承载网中），MTP3B完成信令消息的传递和分发，包括消息识别、消息分配、消息路由控制三个功能，可理解为OSI的网络层；SCCP（信令连接控制部分）是MTP3B的增强，建立面向连接或无连接的网络服务。具体说来，MTP3B以信令链路、OSP、DSP等寻找路由，SCCP则结合了SSN子系统号，SSN区分使用SCCP的软件实体，如RANAP、RNSAP、SCCP管理等。在传输网络控制面内，与传输网络用户面协议一一对应。传输网络用户面的各连接都是由控制面信令控制的。无线网络用户面底层承载为AAL2，适合传送实时性强的话音数据。所以该协议栈为电路域的接口协议。如果是分组域，则承载就是AAL5。以上可以看出，根据话音数据、分组数据的特点，UTRAN采用不同的ATM适配层协议，对于控制信令采用了AAL5，其他用到的AAL还包括AAL0和AAL1（如RNC实现电路仿真业务CES）。此外，UTRAN中还使用了IMA（ATM反向复用技术）、IPOA（IP与ATM结合的技术）等ATM技术，在此不做详细介绍。6.3.2.3MTP-3bTerminationTheconfigurationoftheMTP-3bsignalingpointfunctioninRNCisrepresentedbytheMtp3bSpItu,Mtp3bSpAnsiorMtp3bSpTtcMOtypes,correspondingtodifferentmarket-dependentversionsoftheMTP-3bprotocols.TheexampleinFigure26andTable52arefortheITU-Tversion.EachremotenodeandtypeofsignalingserviceisrepresentedbyanaccesspointforMTP-3bsignaling,Mtp3bAp.TheroutingpossibilitiesforMTP-3bmessagestoeachremotenodeisrepresentedbyconfigurationofsignalingroutesetsMtp3bSrs,signalingroutes,Mtb3bSr,andsignalinglinksets,Mtb3bSls.Figure26RNCMTP-3bSignalingforIuTable52RNCMTP-3bSignalingforIuPos.MO:=Parent:=,...=Comment1MO:Mtp3bSpItu=1Parent:TransportNetwork=1networkInd=NATIONAL_NETWORKsignalingPointCode=ThepointcodeallocatedtoRNCrpuId=ReferencetoPos.1inTable38.2MO:Mtp3bSrs=csParent:Mtp3bSpItu=1(Pos.1)desPointCode=ThepointcodeallocatedtoMSCautoReroute=false3MO:Mtp3bSrs=psParent:Mtp3bSpItu=1(Pos.1)desPointCode=ThepointcodeallocatedtoSGSNautoReroute=false4MO:Mtp3bSls=csParent:Mtp3bSpItu=1(Pos.1)mtp3bSrsId=ReferencetoMOinPos.2.5MO:Mtp3bSls=psParent:Mtp3bSpItu=1(Pos.1)mtp3bSrsId=ReferencetoMOinPos.3.6MO:Mtp3bSr=csParent:Mtp3bSrs=cs(Pos.2)linkSeM3uId=ReferencetoMOinPos.4.priority=17MO:Mtp3bSr=psParent:Mtp3bSrs=ps(Pos.3)linkSeM3uId=ReferencetoMOinPos.5.priority=18MO:Mtp3bAp=csParent:Mtp3bSpItu=1(Pos.1)routeSetId=ReferencetoMOinPos.2serviceInd=3IndicatesSCCPusage9MO:Mtp3bAp=psParent:Mtp3bSpItu=1(Pos.1)routeSetId=ReferencetoMOinPos.3serviceInd=3IndicatesSCCPusage10MO:Mtp3bAp=cqParent:Mtp3bSpItu=1(Pos.1)routeSetId=ReferencetoMOinPos.2(AssumesthatthesameSS7destinationpointcodeisvalidforQ.2630andRANAPtoMSC.)serviceInd=12IndicatesQ.2630usage6.3.2.4SignalingLinkstoMSCandSGSNFigure27RNCSignalingLinksforRANAPtoMSCandSGSNTable53RNCSignalingLinksforRANAPtoMSCandSGSNPos.MO:=Parent:=,...=CommentSignalinglinktoMSC1MO:AtmTrafficDescriptor=U3PMParent:TransportNetwork=1ingressAtmPcr=egressAtmPcr=ingressAtmMcr=egressAtmMcr=ingressAtmQos=CLASS_THREEegressAtmQos=CLASS_THREEATMtrafficdescriptorforSAAL-NNIsignalinglinksforIu.SeeSection4.4.1.2regardingpcrandmcrvaluesSeeSectionserviceCategory=UBR+packetDiscard=true3.2.6.1regardingMOnamingconvention.2MO:VclTp=vc34Parent:...,VpcTp(Pos.3inFigure24)externalVci=34SignalinglinktoMSC.SeeSection2.6.2.4.atmTrafficDescriptorId=ReferencetoMOinPos.1.3MO:Aal5TpVccTp=csaParent:TransportNetwork=1processorId=ReferencetoPlugInUnitforactiveSccpMP,forexample,MS-8inRNC3810andMS-7inRNC3820.SeeSection2.3.2.1andSection2.6.2.4.vclTpId=ReferencetoMOinPos.2fromUserMaxSduSize=280toUserMaxSduSize=280SeeSection4.4.1.4MO:NniSaalProfile=win250Parent:TransportNetwork=1Seeprofile"win250"inSection4.4.1.4.Recommendedprofileforhigh-speedSAAL-NNIsignalinglinkSeeSection4.4.1.5MO:NniSaalTp=csaParent:TransportNetwork=1nniSaalProfileId=ReferencetoMOinPos.4.aal5TpVccTpId=ReferencetoMOinPos.3.MaxSduSize=276SeeSection4.4.1.6MO:Mtp3bSlItu=csaParent:Mtp3bSls=cs(Pos.4inTable52)tpId=ReferencetoMOinPos.5sigLinkCode=0Settodifferentvalues(0-15)fordifferentlinksinthesamesignalinglinksetSignalinglinktoSGSN7MO:VclTp=vc35Parent:...,VpcTp(Pos.3inFigure24)externalVci=35SignalinglinktoSGSN.SeeSection2.6.2.4atmTrafficDescriptorId=ReferencetoMOinPos.18MO:Aal5TpVccTp=psaParent:TransportNetwork=1processorId=ReferencetoPlugInUnitforactiveSccpMP,forexample,MS-8inRNC3810andMS-7inRNC3820.SeeSection2.3.2.1andSection2.6.2.4.vclTpId=ReferencetoMOinPos.6fromUserMaxSduSize=280toUserMaxSduSize=280SeeSection4.4.1.9MO:NniSaalTp=psaParent:TransportNetwork=1nniSaalProfileId=ReferencetoMOinPos.4.aal5TpVccTpId=ReferencetoMOinPos.7.MaxSduSize=276SeeSection4.4.1.10MO:Mtp3bSlItu=psaParent:Mtp3bSls=ps(Pos.5inTable52)tpId=ReferencetoMOinPos.9.sigLinkCode=0Settodifferentvalues(0-15)fordifferentlinksinthesamesignalinglinkset.6.3.2.5SCCPandRANAPFigure28RNCSCCPSignalingforIuTable54RNCSCCPSignalingforIuPos.MO:=Parent:=,...=Comment1MO:SccpSp=1mtp3bSpId=CommonParent:TransportNetwork=1attributesforSCCP.ReferencetoMOinPos.1inTable52.2MO:SccpScrc=1Parent:SccpSp=1(Pos.1)TheSCCProutingcontrolMOholdsperformancemanagementcountersforSCCP.3MO:SccpApLocal=ranapParent:SccpScrc=1(Pos.2)LocalAPforRANAP)ssN=142SubsystemnumberforRANAP=142(3GPPTS23.003).maxConn==NumberofsimultaneousSCCPconnectionsforRANAP.Thevalueofthisattributeshouldbedeterminedbasedontheexpec
