Call Quality Analysis via Termination Data Aggregation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems, particularly in mobile networks, face challenges in accurately analyzing and reporting call quality issues across multiple network elements, leading to difficulties in identifying and addressing problems such as packet loss and jitter that affect speech quality.
Innovation Solution
A system architecture that includes a call report server and analysis server to collect and analyze data from media gateways and switching capabilities, using Megaco/H.248 protocol messages to generate detailed termination and context reports, enabling the calculation of quality parameters like MOS and R-values, and providing real-time visibility into call quality issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If detailed connection analysis is implemented across multiple network elements, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The system divides the complex network into discrete manageable elements (terminations and contexts) that can be individually analyzed. Each termination represents a specific connection point that can be tracked independently, allowing precise measurement without requiring analysis of the entire network at once.
Solution Approach 2:
The patent introduces an intermediary analysis system that collects connection information from multiple network elements and synthesizes it into comprehensive quality reports. This intermediary layer handles the complexity of aggregating data from MGWs, MGCs, and other network components, preventing the complexity from propagating throughout the entire system.
2Loss of information
If comprehensive connection information is collected from multiple network elements, then information completeness is improved, but loss of time increases
Solution Approach 1:
The system collects and stores connection information in advance during normal network operation. Termination and context information is maintained as the network operates, so when quality analysis is needed, the data is already available without requiring additional real-time collection delays.
Solution Approach 2:
The system establishes feedback loops where connection information is continuously monitored and updated across network elements. This ongoing feedback mechanism ensures information remains current and complete without requiring periodic full-system scans that would consume time.

AI summary
A method of generating an analyzed call record comprising the steps of: providing control plane information identifying a plurality of terminations established at a gateway involved in the call; providing user plane information related to terminations used in the call; providing user plane measurement data being associated with respective terminations; analyzing the user plane measurement data in order to produce respective quality indications for respective ones of the plurality of terminations; generating enhanced user plane information incorporating the respective quality indications; and associating together the control plane information and the enhanced termination reports.
