In case of SIM-Swap functionality, I am looking for a way to get the below information from the DIAMETER messages interfacing the HSS… i.e to retrieve the last SIM-Swap performed for a particular mobile user (change of IMSI_IMEI association ?)
It would be great to know if some one lists the reference from 3GPP specification as well…
So far from the 3GPP spec, there is only a way to retrieve whether SIM-Swap is performed or not, but not the timestamp of occurrence. Reference: 3GPP 29.336
