QoE-QoS Mapping for Wireless Communication Resource Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital communication systems fail to effectively correlate quality of experience (QoE) with quality of service (QoS) levels, leading to situations where increased QoS does not necessarily enhance user experience, and users face challenges in selecting optimal QoS levels based on costs and performance.
Innovation Solution
A method and device that determine a user's QoE level for applications in wireless communications devices, mapping it to corresponding QoS parameters, allowing for requests to establish connections with specific QoS settings that meet desired QoE levels, considering user feedback, application types, and environmental factors.

Engineering Contradiction Analysis
1Reliability
If QoS level is increased to improve service quality, then network resource allocation is improved, but user experience does not necessarily improve and costs increase
Solution Approach 1:
The system implements feedback loops where user experience measurements are continuously collected and used to adjust QoS parameter selections. The device monitors user satisfaction metrics and feeds this information back to the QoS negotiation mechanism, allowing dynamic optimization of service parameters based on actual user experience rather than static high-QoS assumptions.
Solution Approach 2:
The invention changes the approach from fixed high QoS parameters to dynamically selected QoS parameters based on measured user experience. The system adjusts multiple QoS parameters (bandwidth, latency, jitter) according to user experience feedback, transforming the rigid parameter selection into a flexible, experience-driven parameter optimization process.
2Productivity
If differentiated pricing is implemented for different QoS levels, then service providers can optimize resource allocation, but users face difficulty selecting optimal QoS levels based on costs and performance
Solution Approach 1:
The system enables users to automatically select optimal QoS levels through the QoE-QoS mapping mechanism without manual intervention. The device autonomously measures user experience, references the mapping table, and selects appropriate QoS parameters, eliminating the need for users to manually evaluate and select from multiple pricing tiers.
Solution Approach 2:
The QoE-QoS mapping table serves as an intermediary between user experience measurements and QoS parameter selection. This mapping mechanism translates subjective user experience metrics into objective QoS parameter choices, bridging the gap between user perception and technical service parameters.
3Reliability
If QoS parameters are set high to ensure quality, then service reliability is improved, but network resource usage increases and costs rise
Solution Approach 1:
The system applies partial action by selecting only the necessary QoS parameters required to achieve satisfactory user experience, rather than consistently applying maximum QoS levels. The QoE-QoS mapping enables the system to use minimal sufficient resources by matching QoS parameters precisely to user experience requirements.

AI summary
Systems, devices and methods are provided for incorporating a quality of experience (QoE) assessment into requests or negotiations for a particular quality of service (QoS) for an application in a communications network. A network may provide service in accordance with a particular set of QoS parameters in order to meet a user's requested QoE. A user may select a particular QoE for an application depending on costs associated with the corresponding sets of QoS parameters available from the network. Functionality to determine the correlation between a user's QoE and sets of QoS parameters may be implemented primarily in a user's electronic communications device, primarily in a network device, or in both of these devices. A separate device may be used for determining the QoE and corresponding sets of QoS parameters for various services or applications.
