1、闸复安切换成功率低问题分析1、指标统计闸复安ALH_3小区从口月18E!开始出现大量的切换失败,切换成功率为0%,全部都是S1的切换失败。口月20日11:00该小区的统计结果如下:S1切换请求次S1切换准备成功次S1切换成功次S1切换成功率S1切换失败次(切换取消)S1切换失败次(timer超时)353400.00%340除了一次准备失败,其它切换失败全部都是切换取消的counter计数。2、切换失败原因分析测试结果:测试过程中UE占用闸复安_3(PCI=191),在小区边缘RSRP-96dBm左右,邻区新成_1(PCI28
2、8)RSRP-89dBm,UE±发了多条测量报告,但是始终未收到切换命令,之后ueHi平恶化掉线:2iTw,e20^»W>^uf3iC»2«»OCCMJAUO7»1407^^14U&72J«11UW22743U072J97®UX>7232»5X23X22U0723M3U0724U07M230U072!U07256S1U07M071ftUtiwemt^tporttUmwww/R■阿tUt・l4jr・g•駅・p“fUt>UKW3、CH.ULDCCM.ULDCCM^ULDCCM.ULDCCH.ULOCCH.ULDCCH-ULQCCMJA7•i0704r)0IU07047MM3MCN.UWAV.昨U^704uoe■加伙0河・・】"00•忡、M«7X>W7■3・•"lorxjUOU・U07W575C4•如0越"8*1厦乜♦4IIEMTime彳ErtmiUd7MT23FrxnR*«3223応応JJJ・tft・Iwt复总安安胃大闸闸IfKKb闸怏血纠⑹砂268冷ooooo1Av席世驀7X18C3333333H43J12<04、25^23)51«97TMVh“191W««J0IM37900C^SRSRPCRS$«*CRSRSRQPmNomFTPPOCPacMACPHYIX冋B0BBooooE1214«1O?11312X2921・》50□TJ•NOENB侧信令结果:从ENB侧的信令来看,发送了切换请求后,很快收到MME发送的切换命令,但是源ENB紧接着发出handovercancel(cause,unspecified,)取消切换:1^12013-11-25141116.01937S100n110071145CTP94KARTOCAT.ACK1^425、2011-11-2)1411100n11007121SlAP47U1d-HandovtrPrep>ratlQn,Hando^«rR«^u1r*dRast«rXnforaatior«lockSysttmXnforaatiorBlockTypt1^432013-11-251411IS.00859510021007114bCTP625M.K1R42011-11-2514111V.OOVO/1100a210014SlAP1d-Marxtoverprep>ration・tundo、"t—andRRCConntctiorRecocf1Q6、uraton1^452013-11-2514IX16.(X»S74100n1100n901d^H«ndover<.ance1.Hirxlovercancel141118.02^218100a1100X1SCTP94H£ARTB£AT1^47201)-11-2$1411“•0222791007111007114vcrp3HtARIMAI^ACK1Q482OH14n1OO4<<1OO•iIIOO.114STTP62SACK1X92013-11-251411IS.10050910071210071SlAP86Han^ov«r<.7、anc«1.HandovtrcanctlAcknowl«d9«19S0?O1i1)2514n18.)OO*»491O<>7111OO712SVTP623K14■[T11«AH71«■区44ar■aHv■8、pv
