UAV Authorization Revocation via Cellular UTM Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems lack efficient mechanisms for authorization revocation in unmanned aerial vehicles (UAVs), which are critical for managing unauthorized or uncontrolled UAV operations within cellular networks.
Innovation Solution
A cellular network system with an unmanned aerial system traffic management function can revoke authorization for UAVs by providing configuration updates and navigation commands, ensuring disconnection from other devices and guiding UAVs to desired locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authorization revocation mechanisms are implemented for UAVs in cellular networks, then network security and operational control are improved, but system complexity and management overhead increase
Solution Approach 1:
The patent introduces a UAS Traffic Management (UTM) function as an intermediary between the cellular network and UAVs. This mediator handles authorization revocation by sending de-registration requests and configuration updates to UAVs, managing the complexity of security control while maintaining network reliability without directly burdening the core cellular network infrastructure
2Reliability
If authorization revocation is implemented for UAVs, then control over unauthorized operations is enhanced, but response time and operational disruption increase
Solution Approach 1:
The system performs preliminary actions by maintaining authorization states and registration information for UAVs before revocation is needed. When revocation is required, the UTM function can immediately send pre-configured de-registration requests and configuration updates, reducing response time while maintaining operational control. The system prepares the infrastructure in advance to enable rapid authorization changes without disrupting ongoing operations

AI summary
Apparatuses, systems, and methods for performing authorization revocation for unmanned aerial vehicles. A cellular network element of a cellular network may receive a request to revoke authorization of a wireless device that is an element in an unmanned aerial system. The cellular network element may provide an indication to the wireless device to disconnect from any other elements of the unmanned aerial system based at least in part on the request to revoke authorization.
