Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication networks face challenges in efficiently managing and securing interactions between unmanned aerial systems (UAS) and cellular networks, particularly in scenarios involving network slicing and interworking between 4G and 5G systems, which affect the quality of service and authentication/authorization processes.
Innovation Solution
A framework is developed to enhance the communication network architecture by integrating service-based architectures and network functions, enabling secure and efficient interactions between UAS and cellular networks, including authentication and authorization mechanisms tailored for UAS services, and supporting network slicing across different generations of wireless technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing communication networks are used for UAS operations, then basic connectivity is provided, but quality of service and security are insufficient
Solution Approach 1:
The patent implements network slicing that divides the communication network into multiple virtual networks, each optimized for specific UAS operations. This segmentation allows different QoS levels and security policies to be applied to different slices, improving reliability for critical operations while managing overall network complexity through modular architecture.
Solution Approach 2:
The patent introduces a UAS service network function as an intermediary between UAS devices and the core network. This intermediary handles authentication, authorization, and service management, improving security and QoS while abstracting the complexity from both the UAS devices and the core network infrastructure.
2Reliability
If network slicing is implemented for UAS services, then service quality is improved, but authentication and authorization processes become more complex
Solution Approach 1:
The patent creates a multi-functional UAS service network function that handles authentication, authorization, and service management in a unified manner. This universal approach improves service quality through consistent policy enforcement while reducing complexity by consolidating multiple functions into a single network element rather than requiring separate systems for each function.
3Stability of the object's composition
If seamless integration between 4G and 5G systems is achieved, then service continuity is improved, but interworking management becomes more difficult
Solution Approach 1:
The patent employs the UAS service network function as an intermediary that manages interworking between 4G and 5G systems. This mediator handles the complexity of inter-system coordination, maintaining service continuity for UAS operations while abstracting the interworking management complexity from network operators and UAS users.

AI summary
A wireless device receives, from a first network, one or more messages comprising an authentication and/or authorization (AA) status of the wireless device indicating whether the wireless device is authenticated and/or authorized for an aerial service, and a parameter indicating that an interface between the first network and a second network is not supported. The wireless device sends, to a network function of the second network, a message, wherein the message comprises the AA status based on the parameter indicating that there is no interface.
