Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In IP networks, quickly isolating the root cause of defects or failures is challenging due to complexity, requiring substantial time and effort from technicians to consult multiple sources across the core IP network, access networks, and customer premises.
Innovation Solution
A method and apparatus that collect and organize call detail records (CDRs) using cause codes, presenting data in a hierarchical representation through multiple screen displays to quickly identify potential root causes of defects, allowing for near-real-time troubleshooting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If technicians manually consult multiple sources to isolate defects, then comprehensive problem analysis is achieved, but time consumption increases substantially
Solution Approach 1:
The patent segments network defect data into structured call detail records (CDRs) with specific fields (cause codes, error types, network elements). This segmentation allows technicians to query specific defect aspects rather than manually reviewing all network sources, achieving comprehensive analysis faster by dividing the problem into manageable data segments.
Solution Approach 2:
The system performs preliminary organization and categorization of network defect data into standardized CDR formats with cause codes before technicians need to analyze them. This preliminary structuring of data enables rapid retrieval and analysis, eliminating the time-consuming manual consultation of multiple unorganized sources while maintaining comprehensive defect isolation capability.
2Reliability
If comprehensive network monitoring is implemented across core IP network, access networks, and customer premises, then defect detection capability is improved, but system complexity increases
Solution Approach 1:
The patent creates a universal CDR data structure that can capture defect information from multiple different network sources (core IP network, access networks, customer premises equipment) using a single standardized format. This multi-functional approach allows comprehensive monitoring across diverse network elements without requiring separate complex management systems for each network segment.
Solution Approach 2:
The system standardizes diverse network defect parameters into uniform cause codes and CDR field structures. By transforming various network-specific defect parameters into a common standardized parameter set, the system achieves comprehensive multi-source monitoring while reducing management complexity through parameter normalization.
3Productivity
If hierarchical display of CDR parameters is implemented, then defect analysis efficiency is improved, but data processing requirements increase
Solution Approach 1:
The patent segments CDR data into hierarchical groups (cause codes, error types, network elements, time periods) that can be displayed and analyzed in organized levels. This segmentation allows technicians to focus on specific defect aspects without processing the entire dataset at once, improving analysis efficiency while managing data processing loads through structured organization.
Solution Approach 2:
The system organizes CDR parameters in hierarchical dimensions (cause code → error type → network element → specific defect), allowing technicians to navigate and analyze defects through multiple organizational layers. This dimensional organization enables efficient defect analysis by allowing selective processing and display of data at different hierarchical levels, reducing the effective data processing load at any given moment.
