Section: 6.3.2 Multiple registrations in same or different serving networks 6.3.2.0 General
Content: There are two cases where the UE can be multiple registered in different PLMN's serving networks or in the same PLMN's serving networks. The first case is when the UE is registered in one PLMN serving network over a certain type of access (e.g. 3GPP) and is registered to another PLMN serving network over the other type of access (e.g. non-3GPP). The second case is where the UE is registered in the same AMF in the same PLMN serving network over both 3GPP and non-3GPP accesses. The UE will establish two NAS connections with the network in both cases. NOTE: The UE uses the same subscription credential(s) for multiple registrations in the same or different serving networks.
