Geo-fence Grouping for Resource-Constrained Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the number of geo-fences increases on an electronic device, it reaches memory and hardware resource limits, leading to inefficient monitoring and potential failure to detect approaches to geo-fences far from the device's current location.
Innovation Solution
The electronic device groups and manages geo-fences by clustering them based on distance, latitude/longitude, or context-aware schemes, selectively monitoring only necessary geo-fences to conserve resources and reduce power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of registered geo-fences increases to provide more location-based services, then service coverage and user experience are improved, but memory and hardware resources are exhausted leading to monitoring failure
Solution Approach 1:
The patent divides geo-fences into multiple groups based on their geographic locations and monitoring priorities. Instead of monitoring all geo-fences uniformly, the system segments them into different monitoring sets, allowing comprehensive service coverage while managing resource consumption within hardware limits.
2Measurement precision
If all geo-fences are monitored continuously, then detection accuracy is improved, but power consumption and resource usage increase significantly
Solution Approach 1:
The patent implements dynamic monitoring where the monitoring set of geo-fences is adjusted based on the device's current location and movement patterns. The system dynamically switches between different geo-fence groups, maintaining accurate detection for relevant areas while conserving power by not continuously monitoring all geo-fences.
Solution Approach 2:
Instead of continuous monitoring of all geo-fences, the system employs periodic monitoring by switching between different geo-fence groups at different time intervals. This allows the device to maintain detection accuracy for active regions while reducing overall power consumption through scheduled monitoring cycles.
3Use of energy by moving object
If the monitoring set is reduced to conserve resources, then power consumption is reduced, but the ability to detect distant geo-fences is lost
Solution Approach 1:
The system dynamically adjusts the monitoring set based on the device's current location, expanding the monitoring range to include distant geo-fences when the device is moving toward them, and contracting the monitoring set when resources are constrained or the device is stationary, thus balancing power consumption with detection capability.

AI summary
Disclosed are a method of managing geo-fences by an electronic device and an electronic device therefor. An operation of the electronic device may include: identifying a deletion of at least some geo-fences among a plurality of geo-fences stored in the electronic device or an addition of other geo-fences; identifying a number of remaining geo-fences among the plurality of geo-fences according to the deletion or the addition; and when the number of remaining geo-fences is larger than a number of geo-fences which can be allowed by hardware resources, grouping the remaining geo-fences as one or more geo-fence groups.
