Online Gaming Quality Score Calculation via Network Parameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no existing method for service providers to objectively measure the perceived quality of online gaming sessions over both wireless and wireline connections, which hinders their ability to assess and improve the quality of service.
Innovation Solution
A device and method that estimate end-user perceived quality of online gaming by using measurable game and transport parameters, such as loading time, packet loss, latency, and jitter, to calculate an objective quality score, specifically a Mean Opinion Score (MOS), which can account for different phases of gaming sessions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If objective models are used to measure QoS for speech, then measurement capability is provided, but no method exists for measuring perceived quality of on-line gaming sessions
Solution Approach 1:
The patent transforms the measurement approach by changing from subjective user reporting to objective parameter measurement. It defines a set of measurable parameters (packet latency, packet loss, jitter, loading time) that objectively reflect gaming quality, enabling reliable QoS measurement without requiring user participation or subjective scoring.
Solution Approach 2:
The patent replaces the mechanical system of subjective user evaluation with an automated objective measurement system. Instead of relying on users to report their experience, the system automatically collects network parameters and game performance metrics, processes them through a quality model, and produces objective quality scores.
2Measurement precision
If network properties are measured, then objective data is obtained, but the perceived quality by end-users cannot be determined
Solution Approach 1:
The patent introduces a quality model as an intermediary that bridges network parameters and perceived quality. This model processes objective measurements (packet latency, loss, jitter, loading time) and transforms them into quality scores that reflect user perception, eliminating the need to directly measure subjective user experience.
Solution Approach 2:
The patent creates a virtual copy of user experience quality through objective parameter measurement. By measuring network parameters and game performance metrics, the system produces a quality score that replicates or mirrors what users would subjectively experience, providing an objective proxy for perceived quality.
3Measurement precision
If different gaming phases are considered, then quality measurement accuracy is improved, but measurement complexity increases
Solution Approach 1:
The patent segments the gaming session into distinct phases (loading phase, playing phase) with different performance characteristics. Each phase has specific parameters that are measured and evaluated separately, then combined to produce an overall quality score. This segmentation allows focused measurement of phase-specific parameters without requiring measurement of all parameters across all phases simultaneously.
