5G QoS Flow Data Processing via PDU Set Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data processing methods in 5G networks do not adequately differentiate or address the unique processing requirements of different Protocol Data Units (PDUs) or PDU sets within the same Quality of Service (QoS) flow, leading to unsatisfied requirements in special scenarios.
Innovation Solution
A method and apparatus for independently and/or jointly processing different data corresponding to the same QoS flow, allowing for differentiated or collective processing based on attributes such as type, importance, association, priority, and dependency, and enabling flexible routing and function application across different paths and protocol layers.

Engineering Contradiction Analysis
1Ease of manufacture
If data processing is performed based on QoS flow or session granularity without distinction, then processing simplicity is maintained, but the ability to satisfy special scenario requirements deteriorates
Solution Approach 1:
The patent segments data processing by introducing PDU set as a new granularity level between QoS flow and individual PDU. Different PDU sets within the same QoS flow can be processed independently with different policies, while maintaining the overall QoS flow structure. This segmentation enables specialized processing for specific scenarios without complicating the entire system.
Solution Approach 2:
The patent applies local quality by allowing different processing characteristics to be applied to different PDU sets within the same QoS flow. Each PDU set can have its own processing requirements, priorities, and handling methods tailored to specific application needs, while the overall QoS flow maintains consistent quality parameters.
2Device complexity
If all PDU sets in the same QoS flow are processed uniformly, then processing complexity is reduced, but processing precision for specific data requirements deteriorates
Solution Approach 1:
The introduction of PDU set granularity divides the uniform QoS flow processing into separable units. Each PDU set can be identified, tracked, and processed with specific precision requirements while maintaining manageable complexity through the structured segmentation approach.
3Manufacturing precision
If differentiated processing is applied to different PDU sets within the same QoS flow, then processing accuracy for specific requirements is improved, but system complexity increases
Solution Approach 1:
The patent manages complexity by segmenting differentiated processing into discrete PDU set units with clear boundaries and identification mechanisms. Each segment can be processed independently with its own rules, avoiding the need for complex holistic processing while maintaining accuracy for specific requirements.
Solution Approach 2:
The system dynamically adapts processing approaches based on PDU set characteristics. The network can flexibly apply different processing policies to different PDU sets within the same QoS flow, allowing the system to optimize for specific scenarios without permanently increasing structural complexity.
