Dynamic Emergency Alert Filtering For Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emergency alert systems for mobile and car applications fail to effectively filter and deliver relevant alert notifications based on geographical location, limiting users to only home or local area alerts, which is inadequate for dynamic and moving conditions.
Innovation Solution
A method and system for dynamically filtering emergency alerts using geographical codes that match the current and predicted location of a user device, allowing alerts for the device's current location, adjacent areas, and expected route, utilizing GPS and navigational data to adjust the filter and provide relevant notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If emergency alerts are filtered based on home or local geographic area, then relevant alerts for stationary users are delivered, but mobile and car applications cannot receive alerts for areas other than home or local geographic area
Solution Approach 1:
The patent applies dynamics by transitioning from static location-based filtering (home area only) to dynamic filtering that updates based on real-time device location. The system continuously monitors device position via GPS and adjusts the geographical code filter accordingly, enabling mobile devices to receive alerts for current and predicted locations rather than being restricted to home areas.
Solution Approach 2:
The system implements feedback by continuously monitoring device location through GPS and using this information to update the alert filtering criteria. The processor receives location data, determines the current geographical code, and adjusts which alerts are delivered based on this real-time feedback, creating a closed-loop system that adapts to user movement.
2Ease of operation
If alerts are filtered by home geographic area, then users receive relevant local alerts, but users in moving conditions are limited to only home area alerts
Solution Approach 1:
The patent applies preliminary action by predicting the device's future location based on current movement patterns and pre-filtering alerts for areas the device will soon enter. This allows the system to proactively deliver relevant alerts before the device actually reaches those areas, improving alert reception efficiency without complicating the user experience.
Solution Approach 2:
The system dynamically adjusts the alert filtering criteria based on real-time device location and movement patterns. Rather than using a fixed home area filter, the system continuously updates the geographical code filter to match the device's current and predicted locations, maintaining simplicity while significantly improving alert reception efficiency for mobile users.
3Device complexity
If a fixed geographical code filter is used, then alert filtering is simple, but the system cannot adapt to changing device location
Solution Approach 1:
The system implements self-service by automatically monitoring device location through GPS and autonomously updating the filter based on real-time position data. The processor continuously determines the current geographical code and adjusts alert filtering without user intervention, maintaining simplicity while achieving high location adaptability.
Solution Approach 2:
The patent applies parameter changes by dynamically modifying the geographical code filter parameter based on real-time device location. The system changes the filter's geographical scope from a fixed home area to a dynamic area centered on the device's current and predicted locations, enabling adaptability without increasing operational complexity.

AI summary
Embodiments of a method for rendering an alert message at a user device and of an emergency alert location filtering system are disclosed. In an embodiment the method comprises determining a current geographical location of the user device, receiving alert messages, each alert message comprising message information and a geographical code, and configuring an alert filter at the user device to allow alert messages to pass the alert filter for rendering at the user device that comprise a geographical code which corresponds to a geographical area in which the current geographical location of the user device is located.
