UAS Network Slice Registration Sequencing to Prevent UUAA-MM Failures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing UAV registration techniques often result in unnecessary UUAA-MM procedure failures due to uncoordinated initiation before the completion of NSSAA procedures, leading to increased power consumption and signaling overhead.
Innovation Solution
A coordinated registration procedure is implemented by network elements to initiate primary authentication, NSSAA, and UUAA-MM procedures in a specific order, ensuring UUAA-MM is only initiated after successful NSSAA completion, thereby avoiding failures.

Engineering Contradiction Analysis
1Productivity
If separate registration procedures are used for UAS and ANSP systems, then each system can be registered independently, but the overall registration process becomes time-consuming and inefficient
Solution Approach 1:
The patent combines the UAS registration system and ANSP registration system into a single unified registration apparatus. The controller receives registration requests from both UAS operators and ANSPs simultaneously, processes them through integrated logic, and coordinates their interactions in real-time, eliminating the need for separate sequential registration procedures and significantly reducing overall registration time.
Solution Approach 2:
The unified registration apparatus performs preliminary coordination between UAS and ANSP registration processes before actual registration is completed. The system pre-establishes communication channels, validates registration data formats in advance, and prepares coordination protocols, allowing the actual registration to proceed more quickly without conflicts or delays.
2Reliability
If multiple independent registration systems operate separately, then system complexity is reduced, but coordination between UAS and ANSP becomes difficult and error-prone
Solution Approach 1:
The unified registration apparatus acts as an intermediary between UAS operators and ANSPs. It receives registration requests from both parties, manages the coordination logic, handles conflicts, and ensures proper sequencing of registration operations. This centralised mediation improves reliability by ensuring consistent coordination rules are applied, while the modular internal structure keeps the added complexity manageable.
3Loss of time
If registration procedures are processed sequentially, then system implementation is simpler, but the registration process becomes time-consuming
Solution Approach 1:
The registration apparatus implements dynamic processing where the registration workflow adapts based on real-time conditions. The controller can switch between sequential and parallel processing modes, adjust the order of operations based on system state, and dynamically allocate resources. This dynamic approach reduces registration time by optimising the process flow while keeping implementation complexity manageable through rule-based decision logic.

AI summary
According to one aspect of the present disclosure, a method of wireless communication of a network element is provided. The method may include initiating a network slice specific authentication and authorization (NSSAA) procedure to register a user equipment (UE) with a network slice associated with uncrewed aerial services. In response to successful registration of the UE with the network slice by the NSSAA procedure, the method may include initiating an uncrewed aerial system (UAS) service supplier (USS) uncrewed aerial vehicle (UAV) authentication and authorization (UUAA) mobility management (UUAA-MM) procedure to register the UE with a USS associated with the network slice. In some embodiments, the USS may maintain the uncrewed aerial services.
