Engineering Contradiction Analysis
1Adaptability or versatility
If existing wireless communication systems use standard QoS management mechanisms, then basic network operations are maintained, but QoS for XR applications is suboptimal due to heterogeneous network conditions and varying device capabilities
Solution Approach 1:
The QoS control mechanism dynamically adapts to varying network conditions and device capabilities by adjusting QoS parameters in real-time. The system monitors network state and device characteristics, then modifies QoS configurations accordingly, transforming a static QoS management approach into a dynamic one that responds to changing conditions.
Solution Approach 2:
The patent changes QoS parameters based on network conditions and device capabilities. By adjusting parameters such as bandwidth allocation, latency requirements, and priority levels according to actual network state and device characteristics, the system achieves optimal QoS performance for XR applications without requiring complete system redesign.
2Productivity
If modular configurations and dynamic protocol stacks are implemented to optimize data transmission, then transmission performance is improved, but system complexity increases
Solution Approach 1:
The protocol stack is divided into modular components that can be independently configured and optimized. By segmenting the protocol stack into discrete functional modules, the system can selectively activate and optimize specific transmission protocols based on network conditions and application requirements, improving overall transmission efficiency while managing complexity through modularity.
Solution Approach 2:
The dynamic protocol stack is designed to perform multiple functions through a unified modular architecture. The same modular framework supports different transmission protocols and QoS configurations, allowing the system to handle various XR application requirements with a single versatile infrastructure rather than requiring separate dedicated systems for each function.

AI summary
A secondary base station receives, from a master base station, a QoS monitoring request for a QoS flow comprising a PDU set of a wireless device, a QoS requirement, for the QoS flow comprising the PDU set, and one or more alternative QoS requirement sets associated with the QoS flow.
