Hi Experts!

Does anyone know which parameter is used to transmit Operator name (not MCC+MNC) over the air interface?

It does not appearing at the phone’s screen.

I believe it is on SIB1. LTE.

None.

This is always been identified by SIB -1 as per MCC and MNC.

In USIM specifications 31.102 you will see param name PNNI, OPLG.

So logic is USIM stores the OPLG once UE Search for frequency based on HPLMN or EPlmn EFS elementary file system will activate the EFSOPLG to extract operator name.

The UE typically receives Network Name and Network Time as a part of the attach process.

This is coming from the MME and transmitted via S1AP protocol in the “EMM Information” message:
