Yes. Currently, the MNID is if the nai format and is overloaded. The MNID in 3GPP specs is the IMSI-NAI (IMSI@REALM), its based on the IMSI. Ex: "<IMSI>@epc.mnc<MNC>.mcc<MCC>.3gppnetwork.org²
We also have MAC48@REALM; We also have approaches to transform MAC to Pseudo IMSI, and then carry IMSI-NAI as the MN-ID. So, we need unique sub-types for each of the types/sources. MN-Id based on IMSI, MSISDN, IMEI, MAC .. Also, do we need to distinguish between IMSI and IMSI-NAI ?
