Adaptive QoS Flow Mapping for Non-Standard 5QI Traffic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G Core (5GC) systems face challenges in efficiently managing quality of service (QoS) flows due to the need for signaling detailed QoS characteristics for non-standard 5QI, which are not adequately addressed by current technologies.
Innovation Solution
A wireless transmit/receive unit (WTRU) receives QoS rules, selects a QoS rule based on data traffic characteristics, and maps service data flows (SDFs) to QoS flows, enabling dynamic adaptation of QoS profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If detailed QoS characteristics are signaled for non-standard 5QI, then QoS management precision is improved, but signaling overhead and system complexity increase
Solution Approach 1:
The patent segments QoS parameters into two categories: standard parameters (5QI, ARP) that use predefined values, and non-standard parameters (GFBR, MFBR) that require explicit signaling. This segmentation allows the system to apply detailed signaling only where necessary, reducing overall signaling overhead while maintaining precision for non-standard QoS requirements.
Solution Approach 2:
The patent introduces a new parameter structure where non-standard QoS characteristics (GFBR, MFBR) are signaled as optional extensions to the existing 5QI framework. This parameter change enables precise QoS management for non-standard cases without requiring complete redefinition of the QoS signaling structure, thus managing complexity.
2Adaptability or versatility
If static QoS profiles are used, then system complexity is reduced, but adaptability to varying traffic requirements deteriorates
Solution Approach 1:
The patent enables dynamic QoS profile selection by allowing the network to choose between standard 5QI profiles and alternative profiles with non-standard parameters based on current traffic requirements. This dynamic approach allows the system to adapt to varying QoS needs without maintaining complex static configurations for all possible scenarios.
Solution Approach 2:
The patent creates a universal QoS framework that can handle both standard and non-standard QoS requirements through a single signaling mechanism. The same QoS rule structure supports both predefined 5QI profiles and alternative profiles with explicit GFBR/MFBR parameters, reducing the need for separate management systems.
3Adaptability or versatility
If multiple alternative QoS profiles are maintained, then QoS rule flexibility is improved, but memory and processing requirements increase
Solution Approach 1:
The patent prepares alternative QoS profiles in advance with predefined non-standard parameters (GFBR, MFBR) that can be quickly selected based on traffic characteristics. This preliminary preparation allows the WTRU to have multiple QoS options available without requiring complex real-time calculations, reducing processing requirements while maintaining flexibility.
Data Source
AI summary
A WTRU may receive a plurality of quality of service (QoS) rules, wherein each of the QoS rules comprises data characteristic label information, receive data traffic, wherein the data traffic comprises service data flows (SDFs). The WTRU may select a QoS rule based on a determined traffic characteristic of the SDFs and the data characteristic label information; map the SDFs to QoS flows based on selected QoS rule; and transmit the QoS flows.
