Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple QoS flows are implemented for diverse data flows, then communication efficiency and signal accuracy are improved, but device complexity increases
Solution Approach 1:
The patent segments service data flows into multiple QoS flows based on different QoS parameters. Each QoS flow is handled by separate network entities (SMF, UPF, RAN) with dedicated processing, allowing differentiated treatment of data packets while maintaining overall system organization through structured segmentation.
Solution Approach 2:
The patent introduces intermediary network entities (SMF, UPF, RAN) that mediate between the application function and the wireless device. These intermediaries handle QoS flow management, packet classification, and resource allocation, reducing the complexity burden on end devices while maintaining efficient QoS control.
2Adaptability or versatility
If device functionality is increased to support sophisticated applications, then service capability is improved, but power consumption increases
Solution Approach 1:
The patent uses intermediary network entities (SMF, UPF, RAN) to handle complex QoS management tasks, reducing the processing burden and power consumption at the wireless device. The intermediaries perform packet classification, QoS flow mapping, and resource management, allowing the device to support sophisticated applications with reduced local computational overhead.
Solution Approach 2:
The patent enables the network infrastructure to self-manage QoS flows through automated SMF selection, PDU session management, and dynamic resource allocation. This self-service capability reduces the need for complex device-side power management while maintaining high service capability.
3Measurement precision
If packet classification and QoS flow management are implemented, then signal accuracy is improved, but processing overhead increases
Solution Approach 1:
The patent performs preliminary packet classification and QoS flow mapping at the UPF and RAN stages, before data transmission to the wireless device. QoS parameters are determined and flows are established in advance, reducing real-time processing overhead at the device while maintaining accurate signal handling.
Solution Approach 2:
The patent introduces intermediary entities (UPF, RAN) that perform packet inspection, classification, and QoS flow mapping, reducing the processing burden on the wireless device. These intermediaries handle the time-consuming classification tasks using efficient algorithms and cached information, minimizing processing overhead while maintaining signal accuracy.

AI summary
This disclosure relates to techniques for supporting multiple Quality of Service flows for a service data flow in a wireless communication system. The service data flow may include multiple categories of data with different Quality of Service parameters. Separate Quality of Service flows may be established for each of the categories of data with different Quality of Service parameters. A cellular network and a wireless device communicating data for the service data flow may apply packet detection rules or packet filters to determine on which Quality of Service Flow to communicate data packets of the service data flow, and may communicate the data packets accordingly.
