Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 4G/5G systems face challenges in implementing enhanced features and functionalities, particularly in network slicing and managing complex interactions between 5G core network elements, such as AMF, SMF, and UPF, which affect registration, connection management, and quality of service (QoS) in scenarios involving unmanned aerial systems (UAS) and varying network access types.
Innovation Solution
The implementation of advanced network functions and interfaces within the 5G system architecture, including enhanced AMF, SMF, and UPF functionalities, along with new protocols and procedures for registration management, connection establishment, and QoS handling, to support diverse network slices and access types, ensuring seamless integration of UAS and improved service continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If enhanced network functions and interfaces are implemented to support diverse access types and network slicing, then service continuity and adaptability are improved, but device complexity and interaction management become more difficult
Solution Approach 1:
The patent introduces an intermediary mechanism that mediates between different network elements (AMF, SMF, UPF) to manage their complex interactions. This intermediary layer standardizes communication protocols and coordination procedures, enabling diverse access types to be supported without proportionally increasing system complexity.
Solution Approach 2:
The network functions are segmented into distinct modular components (AMF for access management, SMF for session management, UPF for user plane functions). This segmentation allows each component to handle specific tasks independently, improving adaptability to different access types while managing complexity through functional separation.
2Reliability
If advanced network functions are implemented to improve registration and connection management, then service continuity is enhanced, but device complexity increases
Solution Approach 1:
The patent implements dynamic network functions that can adapt their behavior based on current network conditions and service requirements. The registration and connection management mechanisms dynamically adjust parameters and procedures to maintain service continuity, reducing the need for overly complex static configurations.
Solution Approach 2:
The system performs preliminary actions during network setup and registration phases to establish service continuity requirements in advance. By pre-configuring failover mechanisms and continuity parameters during initial registration, the system ensures reliable service continuity without requiring complex real-time interventions.
3Reliability
If new protocols and procedures are introduced for QoS handling, then quality of service is improved, but ease of operation decreases
Solution Approach 1:
The patent implements universal QoS handling procedures that can be applied across different network scenarios and service types. The protocols are designed to provide multi-functional QoS management that handles various quality requirements through standardized mechanisms, improving ease of operation compared to scenario-specific approaches.

AI summary
A control plane function receives subscription information indicating that a wireless device subscribes to a service. The control plane function receives, from an authorization server, an authorization for the service of the wireless device. The control plane function sends, to a base station, one or more messages indicating an activation of one or more radio access network functions related to the service of the wireless device, based on the subscription information indicating that the wireless device subscribes to the service and the service being authorized.
