BC95-G Network Registration Status error

Hi.

The ATI response message for the NB-IoT in use is as follows,
Quectel
BC95-G
Revision:BC95GJBR02A03_LGU

We are testing the function of checking the network connection status 12 seconds after hardware reset.

Logs in Test Progress
[Normal]
modemTx->AT+CEREG?
+CEREG:0,2
OK

modemTx->AT+CEREG?
+CEREG:0,1
OK

[Abnormal]
modemTx->AT+CEREG?
+CEREG:0,2
OK

modemTx->AT+CEREG?
+CEREG:0,2
OK

modemTx->AT+CEREG?
+CEREG:0,2
OK

modemTx->AT+CEREG?
+CEREG:0,2
OK
If it is normal, wait about 12 seconds, and within 10 seconds, the network is confirmed to be normal

When abnormal, waiting 12 seconds and reading the status value for 3 minutes did not change the network registration status.

This situation occurs frequently, so I would like to ask you how to normalize communication quickly in case of abnormality.

I want to know, is the terminal registration more likely to succeed, or more likely to fail?
Through the log analysis you provided, the registration may fail due to the reasons of radio signals. If permitted, I need you to provide debug log for detailed analysis

We got debug logs thanks to you.
However, I can’t upload the file because I’m a new user, so I’m sharing it through Google Drive link.

Through the analysis of the Log provided by you, the terminal registration network and sending and receiving data are normal during this period. Please continue to monitor abnormal logs
