QoE Management Framework with Bidirectional Weight Negotiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Quality of Experience (QoE) management frameworks in communication networks lack flexibility in dynamically adjusting QoE parameters during communications sessions, particularly for resource-intensive services, and do not support bidirectional end-to-end negotiation between user equipment (UE) and end devices.
Innovation Solution
A framework that enables bidirectional, end-to-end QoE negotiation by allowing user equipment (UE) to determine and transmit weights corresponding to parameters affecting QoE, which are then adjusted by intermediate network nodes based on network conditions, and ultimately applied by end devices to optimize the communications session.

Engineering Contradiction Analysis
1Adaptability or versatility
If existing QoE management frameworks are used, then QoE parameters can be managed, but flexibility in dynamically adjusting QoE parameters during communications sessions is lacking
Solution Approach 1:
The patent implements dynamic QoE parameter adjustment by enabling real-time negotiation between UE and end devices during communications sessions. The framework allows QoE parameters to be dynamically modified based on current network conditions and user needs, transitioning from static to adaptive management. This is achieved through bidirectional communication protocols that enable continuous optimization of QoE parameters without requiring complete framework redesign.
Solution Approach 2:
The QoE management framework is segmented into distinct functional components: UE-based weight determination, network node weight adjustment, and end device QoE calculation. This segmentation allows each component to operate independently with specific responsibilities, improving flexibility while managing complexity through modular design. The separation enables dynamic adjustment at different levels without affecting the entire system.
2Reliability
If bidirectional end-to-end negotiation is implemented, then QoE optimization is improved, but communication overhead increases
Solution Approach 1:
The patent extracts the negotiation process from traditional centralized QoE management and implements it as a separate bidirectional communication mechanism between UE and end devices. This extraction allows QoE optimization to occur independently through direct negotiation, reducing reliance on extensive centralized signaling. The negotiation messages are streamlined to include only essential QoE parameter information, minimizing overhead while maintaining optimization effectiveness.
3Reliability
If network nodes adjust weights based on network conditions, then QoE management robustness is improved, but processing complexity increases
Solution Approach 1:
The patent implements local quality adjustment by enabling network nodes to modify QoE weights based on their specific local network conditions rather than applying uniform adjustments across the entire network. Each network node independently determines weight adjustments based on its local state (congestion, load, resource availability), allowing robust adaptive management while distributing processing complexity across multiple nodes rather than concentrating it in a single controller.
