modem上报SIM卡状态为unknown问题分析

news 2025/8/9 8:30:59

问题描述：

QCM6125平台上客户反馈了一个问题：

140486 多次切换云卡和物理卡模式出现无法识别物理卡

问题分析：

APP和radio日志分析：

刚开始只有AP日志，看样子SIM卡是识别到了，只是没有激活：

怀疑类似问题：

http://redmine.ukelink.com/issues/139240 手动杀掉进程，出现云卡Ready timeout

问题在于这台设备的卡槽一有一张实体sim卡，当云卡被remove掉后这张实体sim卡起来了并且走到了ready的状态，当modem正在读卡并且将卡状态发送到ap侧时，uservice下发了event 1，关闭了实体卡通道，同时也关闭了实体sim卡。但对于ap侧来说卡一这张卡的session_state已经是activated的，但是还没有更新index_gw_pri_prov的状态，所以当实体sim卡变为absent的时候并没有更新session_state。随后在卡一起云卡的时候由于卡一已经是activated状态，故ap侧未下发激活卡的命令，因此云卡出现了ready timeout。

只是139240问题是物理卡影响了物理卡，而140486问题是云卡影响到了物理卡。因此做类似39240问题的处理：云卡切物理卡时event 3和0也间隔1秒。

modem日志分析：

后面我们复现出modem日志后发现和139240问题不同，仅从qcril卡状态打印来看卡这段时间一直是present:

难道是modem没上报卡状态？查看以前的问题总结：

发现在卡2 从power up开始的整个card_detection期间，卡1有卡状态变化要报给AP时，双卡的extended_card_status的card_state 都是 UIM_EXTENDED_CARD_STATE_UNKNOWN，就是这个原因导致云卡退出时qcril没收到absent的卡状态，再启动物理卡时就没有再进行激活卡的操作。这和SDX55平台的卡问题是一样的，高通的bug。
