Direct C2 Authorization Using SMF Mediation and UAV-C IDs

The SMF acts as an intermediary between the UE and the network authorization system. It receives authorization requests from the UE, forwards them to the appropriate network functions, and relays the authorization decisions back to the UE. This mediator approach centralizes the complex authorization logic in the network infrastructure rather than embedding it in each device, thereby improving security while avoiding increasing device complexity.

The UE is enabled to autonomously initiate authorization requests for C2 communication without requiring manual configuration or intervention. The device automatically manages the authorization process by sending requests to the SMF and processing the received authorization information, allowing self-service operation that simplifies the user interface while maintaining security through standardized protocols.

The authorization request information is preserved and processed in advance before C2 communication is established. The SMF receives and stores the authorization request details, performs necessary validations, and prepares the authorization decision beforehand. This preliminary processing ensures that no critical authorization information is lost during the communication setup phase, while enabling rapid service availability once authorization is granted.

The SMF implements a feedback mechanism where authorization request information is transmitted from the UE, processed by the network, and the authorization decision is fed back to the UE. This closed-loop feedback ensures that authorization information is properly transmitted and received without loss, while the automated feedback process improves service availability by eliminating manual authorization steps.
