Solution Overview
Problem
The rapid growth of unmanned aerial vehicles (UAVs) poses safety and security challenges, necessitating improved methods and apparatus for managing UAVs using wireless networks to ensure secure and efficient identification and tracking.
Innovation Solution
Implementing an Unmanned Aerial System (UAS) traffic management (UTM) system that receives authentication-authorization requests, validates UAV information, and transmits authorization data through a mobile network function, enhancing UAV management by integrating UAV and UAV controller pairing and authorization mechanisms within 3GPP networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UAV management systems are implemented to ensure safety and security, then safety and security of UAV operations are improved, but system complexity and implementation difficulty increase
Solution Approach 1:
The patent combines UAV authentication, authorization, and pairing verification functions into a unified UTM system that leverages existing 3GPP network infrastructure. The AMF integrates multiple management functions including receiving authentication requests from UAVs, verifying pairing information, and coordinating with external authentication servers, thereby improving safety while managing complexity through functional consolidation.
Solution Approach 2:
The patent introduces an authentication server as an intermediary component that mediates between the UTM system and external authentication databases. This intermediary handles the complex verification of pairing information and authorization tokens, allowing the core UTM system to maintain safety and security functions while delegating complex authentication logic to a specialized intermediary component.
2Reliability
If authentication and authorization mechanisms are integrated into UAV management, then security of UAV operations is improved, but processing time and operational complexity increase
Solution Approach 1:
The patent implements preliminary authentication by requiring UAVs to provide pairing information and authorization tokens before flight operations begin. The UTM system verifies these credentials in advance through the AMF and authentication server, ensuring security is established beforehand rather than during critical flight operations, thus minimizing processing time delays during actual UAV management.
Solution Approach 2:
The patent establishes feedback mechanisms where the UTM system receives authentication results and authorization decisions from the authentication server, then uses this feedback to make real-time decisions about UAV operation permissions. This feedback loop enables efficient processing by immediately acting on verification results without requiring repeated authentication checks during flight operations.
3Measurement precision
If remote identification and tracking information is collected and transmitted, then identification accuracy and tracking capability are improved, but data transmission requirements and network load increase
Solution Approach 1:
The patent extracts and transmits only the essential identification and tracking elements required for UAV management, such as pairing information, authorization tokens, and key location data. The AMF and UTM system process and filter the collected information to extract only the critical data elements needed for security and tracking purposes, reducing overall data transmission requirements while maintaining identification accuracy.
Data Source
AI summary
A method includes receiving, by an unmanned aerial system (UAS) traffic management (UTM) from a mobile network function providing UAS management support functionality, an authentication-authorization request including additional UAS management information associated with an unmanned aerial vehicle (UAV); validating, by the UTM, the authentication-authorization request thereby producing authorization data associated with the UAV; determining, by the UTM, information for UAV management including remoted identification and tracking information (RITI); and transmitting, by the UTM to the mobile network function, an authentication-authorization response including the authorization data associated with the UAV and the information for UAV management.
