MTK C2K mdoem log分析

一、網絡釋放鏈接實例

4#主叫端看到10:27(1x系統時間+8小時爲北京時間)1x系統時間 02:27:28.340撥通電話，被叫端收到尋呼page response接入成功後02:27:32.42收到網絡的realease order即被網絡釋放形成被叫端失敗，主叫端隨後 02:27:37.400也被網絡釋放，是被叫端接入成功後被網絡釋放(釋放緣由並未下發，終端也不可得知)形成本次電話失敗，是網絡緣由形成，終端行爲正常。

二、關於終端未收到paging的緣由

3次電話提示沒法接通分析以下：
去電log中3次電話失敗的主叫端撥通時間點：
( 1x 20:17:53.900)(!DO 01:29:12.693)> ETS Id=CP Spy, SpyId=CP IOP ATC recvd data, Data=<CR><LF>^CONN:1,0<CR><LF>
( 1x 20:18:18.740)(!DO 01:29:14.720)> ETS Id=CP Spy, SpyId=CP IOP ATC recvd data, Data=<CR><LF>^CONN:2,0<CR><LF>
( 1x 20:18:43.300)(!DO 01:29:16.933)> ETS Id=CP Spy, SpyId=CP IOP ATC recvd data, Data=<CR><LF>^CONN:3,0<CR><LF>

來電log即被叫端狀況：
在283頻點PN380小區上20:17:45退出業務態後在283頻點PN380小區上每一個1x尋呼週期都正常監聽尋呼，3次主叫撥通時間點後的10多秒內的全部尋呼週期的QPCH信道都指示爲off即快速尋呼信道都指示沒有本終端尋呼，終端始終在PN380小區未作切換中間也未從新作註冊到20:19:29收到尋呼並MT成功(即第4次電話成功)，RSSI約-85dbm小區導頻強度爲-5~-8db信號正常，因此應該是網絡緣由(具體終端也不可得知)未下發尋呼形成前面3次電話未收到尋呼而失敗。

附貼被叫端第2次電話失敗(其餘2次也是如此)監聽尋呼都爲off的log：

三、SRLTE方案中c2kmodem申請不到RF資源

主叫端在14:56:52進入鏈接態RTC - Service Connect Completion，隨後網絡會下被叫尋呼
被叫端：
14:56:54.700快速尋呼信道指示爲非off，14:56:54.800正常醒來準備監聽PCH信道但因爲與MD1的監聽尋呼相沖突而申請不到RF天線資源HSC_RESYNC_DENIED_MSG直到14:56:55.100才收到PCH消息並立刻睡下，因此是C2K監聽尋呼使用天線與MD1監聽尋呼相沖突而申請不到RF資源致使沒收到這次電話尋呼而MT失敗。SRLTE方案是會存在這種狀況的，是正常狀況。

四、小區信號質量變差，網絡未指派好的小區到激活集

在通話中網絡指配了3個激活小區PN126/368/264，而隨後激活小區導頻強度極差<-20db而候選集PN24變得極好終端申請了將PN24加入到激活集，但還沒加上就因激活小區導頻強度極差出現5秒內FFCH譯碼全錯即TC_RELEASE_FADE而掉話。因此是小區信號質量驟變且網絡指配PN24從激活集移除致使的5秒內FFCH譯碼全錯而掉話。
