UAS Authentication Pairing Control in 5G Wireless Networks

The patent introduces a UAS Traffic Management (UTM) system as an intermediary between UAS terminals and the wireless communication network. The UTM handles authentication and authorization functions, separating these security-critical operations from the core network infrastructure. This mediator approach improves security by dedicating specialized security functions to a separate system while avoiding the complexity of embedding full authentication mechanisms in every network component.

The authentication and authorization functions are segmented into distinct modular components: the UAS terminal, the UTM system, and the wireless communication network each have specific, separated responsibilities. The UTM is further divided into specific functional units for location management, authentication, and authorization. This segmentation allows each component to be optimized independently, improving overall security while managing complexity through functional separation.

The patent implements preliminary authentication and authorization procedures where the UTM validates UAS terminals and their intended operations before they access the wireless communication network. Location information and flight plan data are verified in advance, and authorization decisions are made prior to service activation. This preliminary action ensures operational control is established beforehand, preventing unauthorized operations while allowing approved UAS to operate without repeated authentication delays.

The system implements feedback mechanisms where the UTM continuously monitors UAS location information and operational status, comparing actual operations against authorized parameters. When deviations are detected, the system provides feedback by revoking authorization or alerting operators. This continuous feedback loop maintains operational control dynamically without requiring constant re-authentication, balancing security with operational efficiency.
