Solution Overview

Problem

Conventional geolocation methods for mobile devices are inefficient in tracking large, unknown populations due to high resource consumption and low success rates, particularly in detecting consumer entry into targeted areas for marketing purposes.

Innovation Solution

A geolocation device comprising a requester, selector, and tracker that uses passive signaling data to identify mobile devices within a wide area surrounding a target location cell, transitioning to active tracking only when necessary, with adjustable tracking frequencies based on distance and device speed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If active location tracking is performed on a large number of mobile devices, then the precision of detecting consumer entry into target area is improved, but the resource consumption increases significantly

Engineering Contradiction:
Improvedetection precisionVSAvoidresource consumption
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The patent segments the monitoring population into two groups: a first group monitored passively using signaling data, and a second group monitored actively using location tracking. This segmentation allows the system to achieve high detection precision for consumers near the target area while limiting resource consumption by applying active tracking only to a subset of devices that are likely to enter the target area.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies different monitoring qualities to different spatial locations. Passive monitoring using signaling data is applied broadly across a wide area, while active location tracking is applied locally only to devices detected in neighboring cells close to the target area. This local quality approach ensures high precision where needed while conserving resources in broader regions.

Inventive Principle:
Principle #3Local quality

2Use of energy by moving object

If passive collection of information is used to monitor mobile devices, then the resource consumption is reduced, but the success rate of detecting consumer entry into target area decreases

Engineering Contradiction:
Improveresource consumptionVSAvoidsuccess rate
Core Design Contradiction:
Use of energy by moving objectVSReliability

Solution Approach 1:

The patent performs preliminary passive collection of signaling data to identify mobile devices in neighboring cells before the consumer actually enters the target area. This preliminary action allows the system to prepare active location tracking in advance, ensuring high success rate in detecting consumer entry while keeping overall resource consumption low by using passive methods for the bulk of the monitoring.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent uses signaling data as an intermediary to bridge passive and active monitoring. Signaling data serves as a preliminary indicator that triggers subsequent active location tracking. This intermediary approach allows the system to maintain low resource consumption during the passive monitoring phase while ensuring high success rate by activating precise tracking when the intermediary signal indicates a consumer is approaching the target area.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Measurement precision

If active location tracking is performed on all mobile devices, then the detection precision is improved, but the device complexity and processing requirements increase

Engineering Contradiction:
Improvedetection precisionVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments the device population into two categories: devices monitored through passive signaling data collection and devices monitored through active location tracking. This segmentation simplifies the overall system complexity by avoiding the need to implement active tracking for all devices, while still maintaining high detection precision for the subset of devices that require it.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies high-precision active location tracking only locally to devices in neighboring cells near the target area, while using simpler passive signaling data collection for devices in broader regions. This local quality approach reduces device complexity by avoiding unnecessary active tracking for devices far from the target area, while maintaining high precision where it matters most.

Inventive Principle:
Principle #3Local quality
