Question: In a 5G network, when a SUPI contains a GLI, what is the recommended format for the realm part of the NAI if the operator owns a PLMN ID?
Option 1: mcc<MCC>-mnc<MNC>.operatorname.com
Option 2: 5gc.mnc<MNC>.mcc<MCC>.3gppnetwork.org
Option 3: gli<GLI_VALUE>.5gnet.works
Option 4: imsi<IMSIVALUE>@operatorid.mnc<MNC>.mcc<MCC>
Explanation: According to telecom standards for 5G networks, when a SUPI contains a GLI and the operator owns a PLMN ID, the NAI realm should follow `5gc.mnc<MNC>.mcc<MCC>.3gppnetwork.org` for interoperability and clear identification, uniquely associating MCC, MNC with the 5G network of the 3GPP framework.
