Solution Overview

Problem

Existing wireless network systems lack effective methods to determine and monitor location metrics that indicate satisfactory location performance, leading to potential anomalies and reduced user experience.

Innovation Solution

A network management system (NMS) evaluates location performance using metrics such as latency, jitter, dropped requests, AP uptime, and user connect time, with configurable thresholds, to identify anomalies and automatically invoke remedial actions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If location metrics are implemented to monitor wireless network performance, then location performance monitoring capability is improved, but system complexity increases

Engineering Contradiction:

Improvelocation performance monitoring capabilityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments location performance monitoring into distinct metrics (latency, jitter, dropped requests, AP uptime, user connect time), each measuring a specific aspect of performance. This segmentation allows comprehensive monitoring while keeping each individual metric simple and manageable, resolving the contradiction between comprehensive monitoring capability and system complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements feedback mechanisms where location metrics are continuously collected, analyzed, and used to generate insights about wireless network performance. The system provides feedback through configurable thresholds and anomaly detection, enabling automatic responses and continuous improvement without requiring overly complex manual analysis processes.

Inventive Principle:

Principle #23Feedback

2Measurement precision

If multiple location metrics with configurable thresholds are implemented, then location performance evaluation accuracy is improved, but measurement and detection difficulty increases

Engineering Contradiction:

Improvelocation performance evaluation accuracyVSAvoidmeasurement and detection difficulty

Core Design Contradiction:

Measurement precisionVSDifficulty of detecting and measuring

Solution Approach 1:

The patent employs configurable thresholds as adjustable parameters that can be customized based on specific network requirements and performance expectations. By allowing parameter changes in threshold values, the system achieves accurate performance evaluation for different scenarios without requiring complex measurement and detection mechanisms, thus resolving the contradiction between measurement precision and detection difficulty.
