Solution Overview

Problem

Radio-based positioning techniques are compromised by the inclusion of radio models from mobile apparatuses, leading to reduced reliability and accuracy, and users are confused when presented with mixed lists of mobile and fixed location radio network access points.

Innovation Solution

A repository of mobile apparatus identifiers, comprising network interface identifiers, is generated and used to filter observation data, distinguishing between mobile and fixed location access points, thereby improving radio map accuracy and user experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If radio models from mobile apparatuses are included in the radio map, then the quantity of observation data increases, but the reliability and accuracy of radio-based positioning deteriorates

Engineering Contradiction:

Improvequantity of observation dataVSAvoidreliability of radio-based positioning

Core Design Contradiction:

Quantity of substanceVSReliability

Solution Approach 1:

The patent extracts and identifies mobile apparatus identifiers (such as MAC addresses) from observation data, then removes these identified mobile apparatus models from the radio map generation process. This extraction approach allows the system to maintain a comprehensive data collection process while selectively excluding harmful mobile apparatus models, thereby resolving the contradiction between data quantity and positioning reliability

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces an intermediary component (mobile apparatus identifier repository) that mediates between the raw observation data and the radio map generation process. This repository stores identified mobile apparatus identifiers and acts as a filtering layer, allowing the system to process large quantities of observation data while automatically blocking data from mobile apparatuses, thus maintaining both data volume and positioning accuracy

Inventive Principle:

Principle #24Intermediary (Mediator)

2Quantity of substance

If radio models from mobile apparatuses are included in the radio map, then the quantity of observation data increases, but the accuracy of radio-based positioning deteriorates

Engineering Contradiction:

Improvequantity of observation dataVSAvoidaccuracy of radio-based positioning

Core Design Contradiction:

Quantity of substanceVSMeasurement precision

Solution Approach 1:

The patent extracts mobile apparatus identifiers from observation data before the radio map generation process, separating mobile apparatus models from fixed location access points. This extraction ensures that only high-quality fixed location data contributes to positioning accuracy, while maintaining comprehensive data collection for other purposes

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent performs preliminary identification and filtering of mobile apparatus models before the radio map is generated. By conducting this filtering action in advance, the system ensures that the radio map is built exclusively from reliable fixed location access point data, thereby preserving positioning accuracy while still collecting comprehensive observation data

Inventive Principle:

Principle #10Preliminary action

3Reliability

If observation data is filtered to distinguish mobile and fixed location access points, then the reliability of radio-based positioning improves, but the device complexity increases

Engineering Contradiction:

Improvereliability of radio-based positioningVSAvoidcomplexity of filtering system

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements a self-service approach where mobile apparatuses automatically provide their own identifiers (such as MAC addresses) in the observation data. This self-identification mechanism eliminates the need for complex external verification systems, allowing the filtering process to rely on straightforward identifier matching while maintaining high positioning reliability

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent uses simple identifier copying (such as MAC addresses) as the basis for distinguishing mobile from fixed location access points. Instead of implementing complex verification mechanisms, the system relies on copying and matching these simple identifiers against the mobile apparatus repository, thereby reducing filtering system complexity while maintaining reliability

Inventive Principle:

Principle #26Copying

AI summary

An apparatus obtains a respective identifier communication from a respective mobile apparatus and extracts a respective network interface identifier from the respective identifier communication. The apparatus updates or generates a repository of mobile apparatus identifiers based on the respective network interface identifier. The apparatus filters observation data comprising one or more network interface identifiers based on the repository of mobile apparatus identifiers and/or provides the repository of mobile apparatus identifiers for use in filtering the observation data comprising one or more network interface identifiers.
