AT+QNWCFG other information

Hi,
is there a guide that explains the results of these commands?

For exemple, if write AT+QNWCFG = “qci”
what are those numbers?
In this moment i use quectel EM-12

thanks
BR

Where can I find this document?

Our company shares documents internally, but I have not found the complete document at present

Is there an equivalent command for the 5G modules like RN520N-G?
I need to know the QCI values of the registered PDN’s.
