Solution Overview

Problem

Current wireless network fault diagnosis methods are limited to single-point analysis, failing to provide comprehensive fault perception and trend prediction across user equipment areas, leading to inadequate maintenance and user experience issues.

Innovation Solution

A method where a network management server collects and analyzes sampling data from user equipment across areas, generating statistical information on fault types and signal quality to perform area-based wireless network fault diagnosis, enabling timely detection and resolution of network issues.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If single-point fault analysis based on network management system is used, then fault diagnosis can be performed for individual user equipment, but comprehensive fault perception and trend prediction across user equipment areas cannot be achieved

Engineering Contradiction:
Improvefault diagnosis accuracyVSAvoidfault trend information
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The patent segments the fault diagnosis approach into two levels: single-point analysis for individual user equipment and area-based analysis for groups of user equipment. The network management server collects sampling data from multiple user equipments in an area, performs area-based fault diagnosis, and generates statistical information about fault trends, thereby achieving both individual and comprehensive fault perception.

Inventive Principle:
Principle #1Segmentation

2Difficulty of detecting and measuring

If single-point fault analysis is performed, then specific user equipment faults can be identified, but area-wide fault trends and patterns cannot be detected

Engineering Contradiction:
Improveindividual fault detectionVSAvoiddiagnosis system scope
Core Design Contradiction:
Difficulty of detecting and measuringVSDevice complexity

Solution Approach 1:

The patent merges single-point fault analysis with area-based fault analysis by having the network management server collect sampling data from multiple user equipments in an area, perform both individual and aggregate analysis, and generate comprehensive statistical information. This combination enables detection of both individual faults and area-wide fault trends without requiring separate independent systems.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If comprehensive sampling data collection from multiple user equipments is implemented, then area-based fault diagnosis can be performed, but system complexity and data processing requirements increase

Engineering Contradiction:
Improvefault diagnosis comprehensivenessVSAvoiddata collection and processing system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a collection server as an intermediary component that gathers sampling data from multiple user equipments and forwards it to the network management server. This intermediary architecture distributes the data collection burden, simplifies the network management server's workload, and enables comprehensive data collection from multiple sources without proportionally increasing overall system complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)
