Geofence Alert Suppression in Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional geofence alert systems inadvertently send alert messages when the geofence observer enters a vehicle, causing inconvenience, as they do not differentiate between the observer's location and the vehicle's location.
Innovation Solution
A mobile terminal and vehicle management center system that receives location information from the vehicle and unsets the geofence alert function when the observer is within a predetermined distance, allowing for user input to confirm or deny the alert, thereby preventing unnecessary alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the geofence alert system transmits alert messages to the geofence observer's terminal, then the observer is notified of geofence violations, but false alerts are generated when the observer enters the monitored vehicle
Solution Approach 1:
The system performs preliminary location checking before transmitting alert messages. The vehicle management center checks whether the geofence observer's terminal location coincides with the vehicle location before sending alerts, preventing false notifications when the observer is inside the vehicle.
Solution Approach 2:
The system implements a feedback mechanism where the vehicle management center continuously monitors the relative location between the geofence observer's terminal and the vehicle, and dynamically controls alert transmission based on this feedback information.
2Reliability
If the system checks location information continuously, then false alerts are prevented, but communication efficiency and energy consumption increase
Solution Approach 1:
The system performs location checking selectively rather than continuously. Location verification is performed only when geofence violation events occur, not during all operational states, reducing unnecessary communication and energy consumption while maintaining alert accuracy.

AI summary
A control method of a mobile terminal for receiving a geofence service of a vehicle from a vehicle management center includes: receiving location information of the vehicle from the vehicle management center, wherein the location information of the vehicle is transmitted to the vehicle management center from the vehicle when the vehicle is started; checking location information of the mobile terminal; and unsetting a function corresponding to a geofence alert event when the location information of the mobile terminal is calculated to be located within a predetermined distance from the location information of the vehicle.
