CPE Health Scoring System for Reducing Unnecessary Device Swaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Service providers often incorrectly identify customer premises equipment (CPE) devices as defective, leading to unnecessary swaps and increased operational costs due to reverse logistics and field returns.
Innovation Solution
A scoring system is developed to assess the health of CPE devices by integrating various data sources, including current and historical diagnostic data, technical specifications, and network health information, to provide a health score indicating the device's likelihood of being defective.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If CPE devices are swapped based on perceived defects, then service degradation issues are addressed, but unnecessary swaps increase operational costs and reverse logistics burden
Solution Approach 1:
The patent replaces the mechanical field technician inspection and swap process with an automated electronic scoring system that analyzes CPE diagnostic data, network performance data, and historical information to generate a health score, eliminating unnecessary physical device swaps and reducing operational costs
Solution Approach 2:
The patent implements a feedback mechanism where the scoring system continuously receives updated diagnostic data, field technician reports, and reverse logistics test results to refine and update health scores over time, improving the accuracy of defect identification and reducing false positives that lead to unnecessary swaps
2Reliability
If field technicians swap CPE devices frequently, then potential defects are addressed, but the accuracy of identifying truly defective devices decreases
Solution Approach 1:
The patent replaces complex manual field technician assessment processes with an automated electronic scoring system that systematically evaluates multiple data sources including diagnostic data, network performance metrics, and historical information, improving identification accuracy while reducing the complexity of human decision-making
Solution Approach 2:
The patent transforms multiple diverse assessment parameters (diagnostic data, network performance, historical information) into a single standardized health score parameter, simplifying the assessment complexity while maintaining comprehensive evaluation capabilities
3Measurement precision
If comprehensive diagnostic data is collected from multiple sources, then the accuracy of CPE health assessment improves, but the system complexity and data processing requirements increase
Solution Approach 1:
The patent merges multiple data sources including CPE diagnostic data, network performance data, and historical information into a unified scoring system that processes all inputs through standardized algorithms to generate a single health score, improving assessment accuracy while managing system complexity through integration
Solution Approach 2:
The patent creates a universal scoring system that handles multiple types of input data (diagnostic, performance, historical) through a single multi-functional platform, improving measurement precision while avoiding the need for separate complex systems for each data type

AI summary
The present disclosure relates generally to network diagnostics, and more specifically to techniques for determining the health of customer premises equipment (CPE) devices. In certain examples, a scoring system can determine a health score for a CPE device, the health score indicating the health of the CPE device. The health score is determined by receiving, analyzing, and integrating information from different sources, including sources in addition to CPE diagnostic data for the CPE device at the current time. Such sources can include CPE diagnostic data for the CPE device at other times, CPE diagnostic data for other CPE devices related to the CPE device (e.g., in the same household or surrounding area as the CPE device), technical specifications of the CPE device (e.g., make, model and firmware of the CPE device), or per-equalization parameters obtained by the CPE device.
