一、其中MSG_ID_EAS_GAS_ACTIVATE_GCELL_CNF只是指示這個redirection動做完成,但不表明它最後是成功。看隨後上報RATCM_GAS_PLMN_LOSS_IND表明GSM找不到cell脫網了,也就間接說明此次redirect沒有找到合適cell。
或者能夠看看UE有沒有在某個cell創建RR鏈接,能夠經過OTA信令去觀察。

3、重定向過程
網絡在LTE的RRC_connection_release若是攜帶重定向的列表,那麼手機會去搜這個表中的全部頻點去搜小區,按照信號強度排序,首先嚐試信號最強的接收SIB消息,搜夠該小區的SIB小區進行嘗試接入,若是失敗會嘗試第二個小區。
接入到2G的信號要知足C1是最基本的判斷條件。若是不知足C1是不會嘗試接入。
MT端CSFB重定向攜帶的頻點包含了44也包含38,手機這個時候去測量這些頻點尋找小區,此次測量出來38小區的信號比44的好,所以駐留到38小區了。 駐留到38小區以後發起LAU,攜帶CS-MT=1的指示給網絡,這樣的作法至關將paging response帶給網絡,效果是同樣的,這個沒有問題。你能夠看接下來的一通10:21:35也是同樣的行爲,網絡LAU以後應該下發CC_SETUP,可是這通網絡並無下發CC_SETUP而是直接RR__CHANNEL_RELEASE。 以前看到MO端發生了N200超時且信號很是弱,所以覺得是MO端引發的異常致使。如今看來這通掉話是MT端致使的。 --------------------------------------------------------------------------------------------- 掉話CALL: Type Index Time Local Time Module Message Comment Time Different OTA (PCORE) 1014543 86422075 10:20:11:314 RRM_TDD [MS->NW] RR__PAGING_RESPONSE OTA (PCORE) 1051278 86991121 10:20:47:819 EMM_NASMSG [NW->MS] EMM_CS_Service_Notification(paging identity="TMSI_PAGING_TYPE") OTA (PCORE) 1051484 86991138 10:20:47:819 EMM_NASMSG [MS->NW] EMM_Extended_Service_Request(service type="MT_CSFB", CSFB response="CSFB_ACCEPTED_BY_UE") OTA (PCORE) 1051773 86991523 10:20:47:819 ERRC_CONN [NW->MS] ERRC_RRCConnectionRelease(cause:[ReleaseCause_other], redirectInfo:[1]) geran startingARFCN: 44 bandIndicator: dcs1800 (0) followingARFCNs: explicitListOfARFCNs (0) explicitListOfARFCNs: 20 items Item 0 ARFCN-ValueGERAN: 632 Item 1 ARFCN-ValueGERAN: 629 Item 2 ARFCN-ValueGERAN: 622 Item 3 ARFCN-ValueGERAN: 621 Item 4 ARFCN-ValueGERAN: 526 Item 5 ARFCN-ValueGERAN: 521 Item 6 ARFCN-ValueGERAN: 517 Item 7 ARFCN-ValueGERAN: 80 Item 8 ARFCN-ValueGERAN: 79 Item 9 ARFCN-ValueGERAN: 78 Item 10 ARFCN-ValueGERAN: 75 Item 11 ARFCN-ValueGERAN: 72 Item 12 ARFCN-ValueGERAN: 70 Item 13 ARFCN-ValueGERAN: 67 Item 14 ARFCN-ValueGERAN: 65 Item 15 ARFCN-ValueGERAN: 62 Item 16 ARFCN-ValueGERAN: 58 Item 17 ARFCN-ValueGERAN: 41 Item 18 ARFCN-ValueGERAN: 38 Item 19 ARFCN-ValueGERAN: 47 PS (PCORE) 1053305 87001391 10:20:48:486 RRM_TDD [RCS] Sorted power scan list: Index:0 ARFCN:38 POWER:-336 PS (PCORE) 1053306 87001391 10:20:48:486 RRM_TDD [RCS] Sorted power scan list: Index:1 ARFCN:44 POWER:-355 OTA (PCORE) 1053484 87015357 10:20:49:380 RRM_TDD [NW->MS] RR__SI_1 (ARFCN[38], TC[0]) OTA (PCORE) 1053893 87015406 10:20:49:380 MM [MS->NW] MM__LOCATION_UPDATING_REQUEST (LU type: MM_NORMAL_LU) //csmt = 0x01 OTA (PCORE) 1057012 87049289 10:20:51:551 MM [NW->MS] MM__LOCATION_UPDATING_ACCEPT OTA (PCORE) 1058628 87056644 10:20:52:022 RRM_TDD [NW->MS] RR__CHANNEL_RELEASE --------------------------------------------------------------------------------------------- 下一通: Type Index Time Local Time Module Message Comment Time Different OTA (PCORE) 1128068 87736382 10:21:35:419 ERRC_CONN [NW->MS] ERRC_RRCConnectionRelease(cause:[ReleaseCause_other], redirectInfo:[1]) OTA (PCORE) 1129920 87747062 10:21:36:209 RRM_TDD [NW->MS] RR__SI_1 (ARFCN[38], TC[255]) OTA (PCORE) 1130436 87747124 10:21:36:209 MM [MS->NW] MM__LOCATION_UPDATING_REQUEST (LU type: MM_NORMAL_LU) OTA (PCORE) 1133511 87777491 10:21:38:156 MM [NW->MS] MM__LOCATION_UPDATING_ACCEPT OTA (PCORE) 1135140 87784850 10:21:38:627 CC [NW->MS] CC__SETUP
