IMS 注册慢问题分析

news 2024/11/4 12:31:55

1、问题描述

        VOLTE长时间没注册上。

2、Log分析

10-04 15:49:04.745089  2118  3531 D ImsService: enableIms, phoneId = 1
10-04 15:49:04.757739  1423  1498 D RmcImsCtlReqHdl: [1] requestSetImsCfg volte:1, vilte:1, vowifi:0, viwifi:0, sms:1,                 imsTestMode:0, eims:1
10-04 15:49:04.757800  1423  1498 I AT      : [1] AT> AT+EIMSCFG=1,1,0,0,1,1 (RIL_CMD2_READER_3 tid:481754402032)

    从Log看，IMS配置已经发送到Modem了。但是Modem发起PDN建立在15:49:30左右，这个导致IMS注册有明显的延时。

        进一步研究发现，上层发起PDN的建立依赖Modem上报AT< +EIMSPDN通知

如果对IMS感兴趣，可以参考

3、解决方案

        提交MTK Case确认为什么EIMSPDN建立过慢

Dear Customer,

We have checked the logs further, RF resource are fluctuate b/w SIM1 and SIM2.

As we can see from the logs DUT established bearer @ 15:49:04:651, at this time DUT has resource for 2 seconds, Next DUT star RSRS Process and sent to NW, But NW did not respond.

Due to RSRA Process not completed @ 15:49:04:651 modem received ra", "no_ra_initial, and REG was not done.

As we suggested you in previous Note please help to retest DUT/REF parallelly with same Sim card and share logs from bootup.
