Solution Overview

Problem

Existing methods for troubleshooting degraded performance of fixed wireless access (FWA) devices are time-consuming and resource-intensive, often involving unnecessary reboots and reconfigurations, especially when the issue is caused by device relocation rather than weather conditions.

Innovation Solution

A network management system analyzes signal strength changes over time from multiple cell towers to determine if the FWA device has been relocated, using attenuation values to distinguish between relocation and weather-induced signal degradation, thereby preventing unnecessary troubleshooting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional troubleshooting methods are used for degraded FWA device performance, then potential issues can be identified, but network and computing resources are excessively consumed and troubleshooting time is extended

Engineering Contradiction:

Improveperformance degradation detection accuracyVSAvoidtroubleshooting time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary detection by analyzing signal strength patterns from multiple base stations before initiating full troubleshooting procedures. By pre-identifying relocation cases through signal strength changes exceeding attenuation thresholds, the system avoids time-consuming troubleshooting for cases that are clearly caused by device relocation rather than technical faults

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Instead of assuming degraded performance indicates a technical fault requiring troubleshooting, the system inverts the approach by first checking whether the degradation pattern matches relocation characteristics. The system determines that if signal strength changes align with attenuation values for the device's location, the issue is relocation而非 technical failure, thus reversing the traditional troubleshooting initiation logic

Inventive Principle:

Principle #13The other way round (Inversion)

2Reliability

If full troubleshooting procedures including reboots and reconfigurations are performed, then connection issues can be resolved, but network and computing resources are excessively consumed

Engineering Contradiction:

Improveconnection stabilityVSAvoidnetwork resource consumption

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The system extracts and isolates the relocation detection function from the general troubleshooting process. By separately analyzing signal strength patterns against attenuation values before initiating troubleshooting, the system extracts relocation cases and removes them from the resource-intensive troubleshooting pipeline, preventing unnecessary reboots and reconfigurations for relocated devices

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system enables self-service by automatically detecting relocation through signal strength analysis and automatically determining that troubleshooting is unnecessary. This self-diagnosis capability eliminates the need for manual intervention and prevents automatic execution of resource-consuming troubleshooting procedures when relocation is detected

Inventive Principle:

Principle #25Self-service

3Measurement precision

If signal strength analysis from multiple base stations is performed, then relocation can be accurately distinguished from weather conditions, but measurement and detection complexity increases

Engineering Contradiction:

Improverelocation detection accuracyVSAvoidsignal analysis complexity

Core Design Contradiction:

Measurement precisionVSDifficulty of detecting and measuring

Solution Approach 1:

The system applies multi-functionality by using signal strength measurements from multiple base stations for a single comprehensive assessment. Instead of requiring separate detection mechanisms for relocation versus weather conditions, the system uses the same signal strength data from multiple base stations to universally identify relocation patterns through attenuation value comparison, simplifying the overall detection architecture

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A network management system may determine a first change in a first signal strength associated with first signals received by a fixed wireless access device located a first location. The first signals are received by the fixed wireless access device from a first base station. The network management system may determine a second change in a second signal strength associated with second signals received by the fixed wireless access device. The second signals are received by the fixed wireless access device from a second base station. The network management system may determine that the fixed wireless access device has been relocated to a second location based on the first signal strength increasing by at least a first attenuation value and the second signal strength decreasing by at least a second attenuation value.
