Geo-fence Based Mobile Device Connection Termination

The patent applies local quality by differentiating privacy protection levels based on geographic context. When users are far apart, location data is shared openly to enable coordination. When users approach each other (within threshold distance), the system automatically restricts further location tracking. This spatially-variable privacy approach allows efficient meeting coordination while protecting user privacy in close proximity.

The patent implements dynamic privacy management where location sharing parameters change automatically based on real-time conditions. The system continuously monitors distance between users and dynamically adjusts the location sharing state - transitioning from active sharing to terminated sharing when the threshold distance is reached. This dynamic adaptation resolves the contradiction by making privacy protection context-dependent rather than static.

The patent implements periodic location tracking interrupted by termination conditions. Instead of continuous tracking, the system periodically updates location data only when the threshold distance condition has not yet been met. Once users approach each other within the threshold distance, location tracking is automatically terminated. This periodic action with early termination maintains accurate arrival time measurement while significantly reducing energy consumption compared to continuous tracking.

The patent applies the skipping principle by rushing through the location tracking process as quickly as possible once the meeting condition is approached. When the threshold distance is detected, the system immediately terminates location tracking rather than continuing unnecessarily. This rushing through the endpoint of the tracking process eliminates wasteful energy consumption while preserving the accuracy of arrival time measurement up to the meeting point.

The patent applies preliminary action by establishing the threshold distance criterion in advance before the meeting occurs. This pre-defined condition allows the system to automatically terminate location data transmission at the appropriate moment without requiring continuous communication or post-meeting verification. The preliminary setup of the distance threshold ensures reliable meeting confirmation while minimizing unnecessary data transmission overhead.

The patent implements self-service by enabling the location tracking system to automatically terminate data transmission based on the pre-established threshold distance condition. The system monitors its own state and makes autonomous decisions about when to stop transmitting location data, eliminating the need for continuous external coordination or manual intervention. This self-managing approach improves meeting confirmation reliability while reducing network data transmission overhead.
