1. A method of operating a wireless communication network that serves a User Equipment (UE) to deliver UE status information for the UE upon request, the method comprising:
an Access and Mobility Management Function (AMF) exchanging registration signaling with the UE;
the AMF responsively exchanging authentication signaling for the UE with a Unified Data Management (UDM);
the UDM exchanging the authentication signaling with the network;
the UDM responsively transferring a UDM request for the UE status information for the UE to the AMF;
the AMF exchanging network signaling with the UE;
the AMF determining the UE status information for the UE;
the AMF receiving the UDM request for the UE;
in response to the UDM request, the AMF transferring the UE status information for the UE to the UDM;
the UDM receiving the UE status information from the AMF;
the UDM transferring the UE status information to a Unified Data Repository (UDR);
the UDR receiving the UE status information from the UDM;
the UDR receiving a status request for the UE from a network element; and
the UDR responsively transferring 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).
