UAV Authentication Revocation Routing Through UAS Network Functions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems lack effective methods for managing authentication and subscription information changes for unmanned aerial vehicles (UAVs), leading to instability in providing UAV services due to mobility-related signaling issues.
Innovation Solution
Implementing a method and device for managing UAV authentication and authorization revocation, and notifying network entities of changes in aerial subscription information through UAS network functions, including UAS NF, AMF, and SMF, to ensure stable UAV service provision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If UAV mobility is supported to enable dynamic service provision, then service coverage and adaptability are improved, but authentication and subscription management become unstable due to frequent location changes
Solution Approach 1:
The patent introduces a UAS NF (Unmanned Aerial System Network Function) as an intermediary entity between the UAV and the core network. This UAS NF acts as a dedicated mediator that handles authentication, authorization, and subscription management specifically for UAVs, isolating the mobility management complexity from the core network while maintaining stable authentication services despite frequent UAV location changes
2Device complexity
If traditional network architecture is used to maintain system simplicity, then device complexity is reduced, but UAV-specific authentication and subscription management cannot be effectively implemented
Solution Approach 1:
The patent segments the network architecture by introducing a dedicated UAS NF layer between the traditional core network and UAV services. This segmentation allows the core network to remain simple and unchanged while the UAS NF handles UAV-specific functions including authentication, authorization, and subscription management, thus adding UAV adaptability without increasing overall system complexity
Solution Approach 2:
The UAS NF is designed as a multi-functional entity that simultaneously handles authentication, authorization, and subscription management for UAVs. This universal component provides multiple UAV-specific services through a single network function, avoiding the need for separate dedicated systems for each function and thereby maintaining architectural simplicity

AI summary
The disclosure relates to a 5th generation (5G) or 6th generation (6G) communication system for supporting a higher data transmission rate. A method performed by an unmanned aerial system network function (UAS NF) in a wireless communication system providing a UAS service for an unmanned aerial vehicle user equipment (UAV UE) is provided. The method includes receiving, from a UAS service supplier (USS), a first message including information on a UAV USS authentication and authorization (UUAA) revocation for the UAV UE, identifying UUAA information for the UAV UE, determining, based on the UUAA information, a network entity to which the information on the UUAA revocation for the UAV UE is to be notified, and transmitting, to the network entity, a second message including the information associated with the UUAA revocation for the UAV UE.
