基于信令的感知指标体系梳理思路、举例1、思路1、正常流程分析2、提炼感知指标3、提炼感知关联指标4、确定感知指标及关联指标算法（定位感知指标某一项比较差的原因）5、异常状况分析：定位原因（信令层面的原因）a、信令上明确指示失败的。b、由于超时引起的。6、形成感知指标体系7、形成规范2、举例以普通主叫（不带彩铃，不带V网，被叫号码没有呼转，没切换）为例：正常流程如下：信道请求(CHAN-REQ)AMSBSSMSCVLR鉴权响应CM业务接受加密模式命令加密模式完成（CIPMODCOM）加密模式命令（CIPMODCMD）CM-业务接受（CM-SERV-ACC）鉴权响应（AUTH－RES）AUmBSSAPAMAPBHLRMAPDBSSAPAAUCBBSSBMSUm启动加密（START-CIP）接受接入请求（ACPACCESREQ）收到响应，VLR核对鉴权响应，如相符，继续处理，否则，拒绝该用户业务请求业务请求（CM-SERV-REQ）鉴权请求鉴权请求（AUTH－REQ）CM-业务请求（CONN-REQ）CON-CONF(接续确认)CC处理接入请求（PROCACCESREQ）启动鉴权鉴权参数请求AUT-INFO-REQAUT-INFO-PROY立即分配(IMMED-ASSIGN)鉴权参数响应鉴权响应（AUTH－RES）加密模式完成BSSAPAMAPBMAPDAMSBSSMSCVLR建立呼叫（SETUP）指配请求（ASSIGN-REQ）指配完成指配完成（ASSIGN-COMP）指配请求（ASSIGN-REQ呼叫继续（CALLPROC）建立呼叫（SETUP）AUmHLR被叫所在VLR为去话发送信息（S.F.O.C）完成呼叫(回主叫用户数据COMCALL）路由信息回送（RoutingInfotmationResp)路由信息请求（SendRoutingInformation）提供漫游号码（ProvideMSRNReq）回送漫游号码（PROVMSRNResp）呼叫继续（CALLPROC）IAI(IAM)MSC用户感知指标梳理如下：接入类：1、端到端接通率2、接续时延保持类：1、非主叫、被叫明确挂机引起的通话流程结束。通话质量类：感知指标定义如下：接入类：接通率指标定义：手机振铃次数+（手机未振铃，但原因为被叫用户忙、被叫用户关机、用户拨打无效号码等与网络无关原因）/发起呼叫次数端到端接通率关联指标：1、接入成功率=ESTIND(CMServiceREQ)/ChannelRQD,如下图：、接入成功率关联指标：2、业务请求成功率=CMServiceACC/CMServiceREQ业务请求关联指标：接续确认率、鉴权请求成功率3、呼叫建立成功率=Alerting+（手机未振铃，但原因为被叫用户忙、被叫用户关机、用户拨打无效号码等与网络无关原因）/SETUP关联指标：TCH分配成功率、取被叫用户路由成功率、局间接续成功率8、异常状况分析：定位原因（信令层面的原因）a、信令上明确指示失败的。b、由于超时引起的。1、异常流程：A、信令上明显指示失败的ChannelACTChannelACTACKIMMASSCMDBTSBSCMSCMSChannelREQSABMESTIND(CMServiceREQ)CR(CMPL3information)CCSetupCallProceedingASSREQASSCMDSABMESTINDASSCMPASSCMPAlertingConnectConnectACKTalkingDISCRELRELCMPClearCMDClearCMPCMServiceAcceptedChannelACTChannelACTACKUAUAChannelRELRELINDDeactiveSACCHRFChannelRELRFChannelRELACKDISCUARLSDRLSDCMP(1)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(27)(28)(29)(30)(31)(32)(33)(34)(35)(36)(37)(38)(39)(40)(26)ChannelRQD(2)失败点：如上图：1、信令流程到(4)若收到Channelactivationnegativeacknowledge可能原因为：...102、信令流程到（5）若收到Immediateassignmentreject原因为：...........................143、信令流程到（11）若收到CMservicereject原因为：...........................................154、信令流程到（8）若收到CMserviceabort原因为：.............................................165、信令流程到（16）若收到Channelactivationnegativeacknowledge可能原因为：166、.信令流程到（21）若收到AssignmentFailure原因为：.......................................20原因描述：1.信令流程到(4)若收到Channelactivationnegativeacknowledge可能原因为：原因分类：Class(000):NormaleventClass(001):NormaleventClass(010):ResourceunavailableClass(011):ServiceoroptionnotavailableClass(100):ServiceoroptionnotimplementedClass(101):Invalidmessage(e.g.parameteroutofrange)Class(110):ProtocolerrorClass(111):Interworking详细原因如下：ClassValueCauseDiagnostics000----NormalEvent0000000radiointerfacefailureChannelNumber0000001radiolinkfailureChannelNumber0000010handoveraccessfailureChannelNumber0000011talkeraccessfailureChannelNumber0000100reservedforinternationaluse0000101reservedforinternationaluse0000110reservedforinternationaluse0000111O&Mintervention0001000reservedforinternationaluse0001:::00011100001111normalevent,unspecified001----NormalEvent0010000reservedforinternationaluse0010:::00101110011000reservedfornationaluse0011:::0011111010----Resourceunavailable0100000equipmentfailure0100001radioresourcenotavailableChannelNumber0100010terrestrialchannelfailureChannelNumber0100011CCCHoverloadChannelNumber0100100ACCHoverloadChannelNumber0100101processoroverload0100110reservedforinternationaluse0100111BTSnotequipped0101000remotetranscoderfailureChannelNumber0101001notificationoverflowChannelNumber0101010reservedforinternationaluse0101011reservedforinternationaluse0101100reservedfornationaluse0101101reservedfornationaluse0101110reservedfornationaluse0101111resourcenotavailable,unspecified011----ServiceorOptionNotAvailable0110000requestedtranscoding/rateadaptionnotavailableChannelNumber0110001reservedforinternationaluse011::::01111100111111serviceoroptionnotavailable,unspecified100----ServiceorOptionNotImplemented1000000encryptionalgorithmnotimplementedChannelNumber1000001reservedforinternationaluse1000:::10001111001000reservedfornationaluse1001:::10011101001111serviceoroptionnotimplemented,unspecified101----InvalidMessage1010000radiochannelalreadyactivated/allocatedChannelNumber1010001reservedforinternationaluse1010:::10101111011000reservedfornationaluse1011:::10111101011111invalidmessage,unspecified110----ProtocolError1100000messagediscriminatorerrorMessageDiscrim1100001messagetypeerrorMessageType1100010messagesequenceerrorMessageTypeETSI3GPPTS08.58version8.6.0Release199969ETSITS100596V8.6.0(2000-11)ClassValueCauseDiagnostics1100011generalinformationelementerror1100100mandatoryinformationelementerrorElementIdentif1100101optionalinformationelementerrorElementIdentif1100110informationelementnon-existentElementIdentif1100111informationelementlengtherrorElementIdentif1101000invalidinformationelementcontentsInform.Element1101001reservedforinternationaluse1101010reservedforinternationaluse1101011reservedforinternationaluse1101100reservedfornationaluse1101101reservedfornationaluse1101110reservedfornationaluse1101111protocolerror,unspecified111----Interworking1110000reserve
