6G QoE-Aware QoS Flow Control for WTRU Network Sessions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to accurately account for the subjective nature of quality of experience (QoE) in managing network flows, leading to suboptimal network adjustments that can impair user experience despite adequate QoS metrics.
Innovation Solution
Implementing a wireless transmit receive unit (WTRU) that transmits QoE assistance information for quality-of-service (QoS) management, allowing for dynamic adjustments based on real-time QoE monitoring and feedback to a QoE-Aware Quality-of-Service Function (QQF).
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If QoS metrics are used to manage network flows, then objective service parameters are controlled, but subjective user experience quality is not accurately reflected
Solution Approach 1:
The patent introduces a QoE measurement entity that acts as an intermediary between the network system and users. This entity collects subjective QoE feedback from users and translates it into objective measurement data that can be integrated with existing QoS metrics, thereby improving QoE measurement accuracy without requiring direct modification of the entire network system.
Solution Approach 2:
The patent segments the QoE management system into distinct functional components: QoE measurement entity, QoS management entity, and network flow control components. This segmentation allows the complex QoE measurement and management functionality to be implemented as modular additions to the existing network infrastructure, managing system complexity through functional decomposition.
2Productivity
If network adjustments are made based on QoS metrics alone, then network performance parameters are optimized, but user experience quality may be impaired
Solution Approach 1:
The patent implements a feedback mechanism where QoE measurements from users are continuously collected and fed back to the QoS management entity. This feedback loop enables the system to adjust network resource allocation based on actual user experience rather than relying solely on theoretical QoS metrics, thereby improving user experience quality while maintaining network efficiency through data-driven decisions.
Solution Approach 2:
The patent enables dynamic adjustment of QoS parameters based on real-time QoE measurements. The system can adaptively modify network resource allocation, bandwidth assignment, and service prioritization according to actual user experience conditions, allowing the network to respond dynamically to changing user needs and maintain high user experience quality.
3Loss of information
If QoE measurements are collected from users, then subjective experience quality is captured, but system complexity and measurement difficulty increase
Solution Approach 1:
The patent introduces a QoE measurement entity as an intermediary that simplifies the process of collecting user experience data. This entity provides standardized interfaces and methodologies for capturing QoE measurements, reducing the complexity for both users providing feedback and the system processing the data, thereby reducing measurement difficulty while capturing comprehensive user experience information.
Solution Approach 2:
The patent uses objective measurements and determinations as copies or proxies for direct subjective user feedback. When direct user input is difficult to obtain, the system can use correlated objective metrics as representations of user experience, reducing measurement difficulty while still capturing essential user experience information through these proxy measurements.

AI summary
The present disclosure is directed to implementations of systems and methods for quality-of-experience (QoE)-aware quality-of-service (QoS) management for network flows. In some implementations, a wireless transmit receive unit (WTRU) may transmit to a network a registration request comprising quality-of-experience (QoE) assistance information. The WTRU may receive, from the network, a registration acceptance response indicating a QoE-Aware Quality-of-Service Function (QQF) of the network is configured to provide flow control or QoS management for an application of the WTRU based on the QoE assistance information. The WTRU may execute the application and monitor a QoE score during execution of the application. Responsive to a change in the QoE score, the WTRU may transmit to the QQF one or more network or application performance measurements.
