1. A method of operating a wireless communication network that comprises a Network Exposure Function (NEF) and an Access and Mobility Management Function (AMF) to register a User Equipment (UE), the method comprising:
an Application Function (AF) receiving a UE instruction from an external application server, generating a northbound Application Programming Interface (API) call that has the UE instruction, and transferring the northbound API call that has the UE instruction to the NEF;
the NEF receiving the northbound API call that has the UE instruction, translating the northbound API call that has the UE instruction into an AMF API call that has the UE instruction, and transferring the AMF API call that has the UE instruction;
the AMF receiving the AMF API call that has the UE instruction, translating the UE instruction into a registration message that has a registration cause, and transferring the registration message that has the registration cause;
the UE receiving the registration message that has the registration cause, and in response, identifying networking data based on the registration cause and performing a registration based on the networking data; and

the AMF transferring the registration message that has the registration cause comprises transferring a registration rejection that has the registration cause responsive to receiving a registration request.
