Geolocation-Based Mobile Alert System for Dynamic Event Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems fail to provide alerts to mobile device users who are on the move and approaching an event location, as they are limited to fixed locations and do not account for users' dynamic geographical positions.
Innovation Solution
A method and communications network that detect events and send alerts to mobile devices based on their geographical location, using sensors or mobile device reporting, with processing and forwarding of information through service provider sites, utilizing GIS/GPS systems for location identification and image recognition to determine event type and location, enabling direct or indirect alert messaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If alert systems use fixed locations such as pre-installed electronic signals or wired telephone lines, then alerts can be provided to stationary entities, but alerts cannot be provided to mobile device users who are on the move and approaching the event location
Solution Approach 1:
The system transitions from static fixed-location alerting to dynamic mobile device alerting by continuously tracking device locations via GPS and sending alerts to mobile devices based on their real-time positions relative to event locations, enabling reliable alert delivery to moving users
Solution Approach 2:
The system serves multiple functions: it provides alerts to both traditional fixed locations and mobile devices, supports various event types (natural disasters, accidents, public safety incidents), and works across different geographic locations, making the alert system universally applicable to diverse scenarios
2Loss of time
If the system provides alerts to all mobile devices within a geographical area, then mobile users can receive timely warnings, but the system complexity increases due to location tracking and device identification requirements
Solution Approach 1:
The system performs preliminary actions by establishing service provider sites that maintain databases of mobile devices and their locations in advance, so when an event occurs, alerts can be quickly targeted to relevant devices without complex real-time computation
Solution Approach 2:
Service provider sites act as intermediaries between the event detection system and mobile devices, handling the complex tasks of location tracking, device identification, and alert routing, thereby simplifying the overall system architecture and reducing direct complexity
3Measurement precision
If the system uses sensors to detect events above a predetermined threshold, then event detection accuracy is improved, but the system requires more sophisticated sensing and processing capabilities
Solution Approach 1:
The system changes the parameter for event detection from complex multi-sensor analysis to simple threshold-based detection of predetermined event types, maintaining adequate detection accuracy while significantly reducing sensing and processing complexity
Solution Approach 2:
The system uses simple, inexpensive sensor implementations that detect events based on predetermined thresholds rather than complex sensing arrays, accepting that individual sensors may have limited capabilities but compensating through the network effect of multiple service provider sites

AI summary
A system, method, and computer readable medium for providing information to a mobile device based on an event comprising detecting an occurrence of the event, determining if the event is a specific event and if the event occurred at or near a geographical location and sending an alert of the event to at least one mobile device if the event is the specific event, if the event occurs at or near the geographical location, and if the at least one mobile device is located at or near the geographical location.
