Communications Assurance Analysis for Radio Call Path Degradation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Diagnosing faults in radio communication systems, particularly in public safety networks, is complex due to the varied impact of faults on different members of a talkgroup, making it difficult to identify and address issues affecting communication during incidents.
Innovation Solution
A communications assurance analysis system provides a visual representation of the communication path from call initiator to recipients, aggregating metrics to display degradation levels at each stage, allowing technicians to identify and address problems affecting single or multiple radios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional fault diagnosis methods are used in radio communication systems, then technicians can identify faults, but the process is complex and time-consuming due to varied impact on different talkgroup members
Solution Approach 1:
The patent segments the communication path into distinct stages (mobile device, radio access network, core network, recipient mobile device) and analyzes faults at each stage separately. This segmentation allows technicians to isolate and identify faults more efficiently by examining each component individually rather than analyzing the entire system as a whole, thereby reducing diagnosis time while maintaining accuracy.
Solution Approach 2:
The patent introduces a new dimension of analysis by creating a visual representation of the communication path that displays multiple parameters (signal strength, error rates, latency) simultaneously across different stages. This dimensional expansion transforms complex multi-parameter fault data into an intuitive visual format, enabling faster identification of degradation sources without sacrificing measurement precision.
2Measurement precision
If detailed analysis of each communication stage is performed, then fault accuracy improves, but system complexity increases
Solution Approach 1:
The patent introduces an intermediary visualization layer that mediates between the complex underlying communication stages and the technician. This intermediary representation aggregates and presents fault information in a simplified visual format, maintaining the precision of detailed analysis while reducing the perceived complexity for the user through intuitive graphical display of communication path health.
3Difficulty of detecting and measuring
If comprehensive metrics are collected across all communication stages, then fault identification capability improves, but data processing complexity increases
Solution Approach 1:
The patent extracts and isolates specific critical metrics from the comprehensive data set at each communication stage, focusing analysis on the most relevant parameters for fault detection. By extracting only the essential performance indicators needed for fault identification rather than processing all available data, the system maintains high detection capability while reducing processing complexity.

AI summary
Techniques for communications assurance analysis are provided. A communications assurance analysis system retrieves performance points of a plurality of stages of a single radio call. A level of degradation for each stage of the plurality of stages of the single radio call is determined based on the performance points. A visualization of each stage of the single radio call is displayed. The visualization is in order of a communications path between an initiator of the single radio call and at least one recipient of the single radio call. The visualization for each stage of the plurality of stages is based on the level of degradation for the stage.
