Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for managing voice call quality over packet-switched networks are limited to end-to-end voice analysis, failing to efficiently determine and address poor voice call quality issues.
Innovation Solution
A method and apparatus that utilize per-link muting ratios calculated from log information collected by base stations to generate voice call quality information, allowing for efficient quality management and identification of quality issues within the mobile network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If end-to-end voice analysis is used for quality management, then voice call quality can be assessed, but the method is limited and cannot efficiently determine poor quality causes
Solution Approach 1:
The patent segments the end-to-end voice analysis into per-link quality measurements. Instead of treating the entire network path as a single analysis unit, it divides the network into multiple links (e.g., access link, backhaul link, core network link) and performs quality measurement on each segment independently using log information from base stations. This segmentation enables identification of specific link quality issues that contribute to overall poor voice call quality.
2Productivity
If per-link muting ratio calculation is implemented, then quality management efficiency is improved, but system complexity increases due to log information collection and processing
Solution Approach 1:
The base station performs self-service by automatically collecting log information and calculating per-link muting ratios without requiring external intervention. The system uses existing log information that is already being collected for other purposes, and automatically processes this data to generate quality metrics. This self-service approach improves quality management efficiency while minimizing additional system complexity.
Solution Approach 2:
The log information collection mechanism serves multiple functions: it is used for both traditional network operations and for calculating per-link muting ratios for quality management. By making the log collection system multi-functional, the patent avoids the need for separate dedicated measurement infrastructure, thereby improving efficiency without proportionally increasing system complexity.
