Volte呼叫信令流程資料

頁腳頁腳終端開機的IMS注冊過程:用戶開機以后，首先完成附著過程，附著完成以后，發(fā)起IMS注冊過程。在IMS注冊流程中，先建立QCI=5的SIP信令承載。然后進行SIP的注冊過程，當完成注冊過程以后，就可以進行VoLTE呼叫了。SIP信令的注冊過程如下圖所示。「E才Mff533jeS d;Type231CIT311「二河Jt上|*gklkl. .,!u-4同工fft"叩刎I9€.|_H_GC.H23112T9014MM期M所啪加Rl/KBOOH.BOH|H，WMHfAlt.wh日同甲IT就|EPBvhiZE1I3T361?HF?匚GornErlluEfi■日qu日引GGGH.ULmnijM4RR3C0rnie:1lc-SetjpCCCM_DL13:1DirjeijtF:RCCM,ine:iiDjJsijpLsm^ece-KCHJAU1K3T293*OLP疝伊同jrlTr&g的「DC&bLDL33ir"期*in白riw胃上口」白女FPErihl53103?29]iIdenltv^esiioraeEP￡klkl211137291.UUrtfanmaignTfanTEi1DCCHJJLJ31137561*OLInrlhm^i-nTghq加KckjotSMMMMJ4ijfrBn1>ralienRf中JB寸EPB『MZTIl-irOB7wAi-rtFenfT3tt?nr■電弓仲口惦三EF5ItaihlniEaraa4DCCIHJJL^iiDjrnB4D'Lj^mmonTrininrDCCH_DL?31537745*即l*麻如面匚口rnmarEFPBinhl211?37745,Se:jrif?IMAJeCjmileteEPE始hl^3.1BJr745/UUnurnalijnTrsn-slerDCCHIJLnii37m40|_1咖「口外”|1nJh『DCCH_t>L制iutmSBDZld:Eg?1「位rmnii"E日利爭口E-R卻23：1[1:37.750,UU-uTamali3nT-ansaErDCCH_IJLMEuai4UEC電曲◎川鵬上力dURDCCbLDL231Q43239tUECtFMllMnim.adlan■窗即3憤工小卡「不偷就停DCUHJJLaiuaaiDCCH_Dl331C421521￡ec」小包口曲匚的黨的DCCHJJL311C421BJ:RRECorinnzliarPncC'nEqursliar—DC"_DL,,■■1*.■.rfi'SCCUH而印W市H」由制力rCQFnph!yDCCH.ULp3lC43JR：1峨=41皿11fxi|E『M■<■：4出口mDsfiuitEFSBei'HrConiFfl^enue-FlEPS fl23：1E4129Bji出口?加L'BriUlCEFS365-BhCDhUeXlAZCCPtEF53MjJ.IL心卻喟*M<h1。巾割電虺EPSMM'''s_''■'卜仙“旭「小小近切「DCCM_UL：■1「4-1A1P「i"Cl]?巾HHIfF中懺;lFPESM|JI口44.DfaUunii-rtisicnr-anygrDC*iJL1*ITfWrhfriJCiXiiiB^liij^R^cfinguralrirDCC-i.lX.23U43洞*RRiJCof'ninrlinRncn^3ijra1iirCijipph,'iKCi-LA0L.!■,$^cbvihBDefeultEFBBEiarorCnnkeortEFB5M23：,1L13.573Ai：ca=rteDersuitEFS!0e?'5rCnnie：irtj4Ci：€ptEJF5SM2J.ICH」」UL而上扁3HI■?勒ri"亦bCCH_LILa1US741帆也把ur”n西川即口浦WXKJJL?|1J46372dEEGIHTER◎SIP23-IB45303>PE^ISTEfT401GSFniUKMIRE0怕「￡艮6SIP2MQ47J2J*R匚。口1r￡R3(J0WSIP231847331BUBaC^IBE行，SEP231U<75434SUESCAIBE,200下,SIP23.104754.3jtjcmFYmSlPaimu?4NOTIFY20dE,Q>P
