the UDM configured to:
exchange the authentication signaling with the AMF; and
responsively transfer a UDM request for the UE status information for the UE to the AMF;

the AMF configured to:
exchange network signaling with the UE;
determine the UE status information for the UE;
receive the UDM request for the UE; and
in response to the UDM request, transfer the UE status information for the UE to the UDM in response to the UDM request;

the UDM configured to:
receive the UE status information from the AMF; and
transfer the UE status information to a Unified Data Repository (UDR) the UDR; and

the UDR configured to:
receive the UE status information from the UDM;
receive a status request for the UE from a network element; and
responsively transfer the UE status information for the UE to the network element, wherein the network element comprises one of an Application Function (AF), Network Exposure Function (NEF), Home Subscriber System (HSS), and Telephony Application Server (TAS).
