Selective Emergency Alert Processing on Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Emergency Alert System (EAS) technologies do not allow subscribers to selectively receive and manage EAS messages based on their preferences regarding alert types, time periods, and actions, leading to unnecessary notifications and information overload.
Innovation Solution
Implementing an enhanced EAS message system that includes parameters such as alert type, time, geographic extent, originator, and severity, allowing subscribers to configure and process messages according to their preferences, with options to render, save, or ignore alerts based on these parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If EAS messages are broadcast to all subscribers, then alert coverage is maximized, but information overload and unnecessary notifications increase
Solution Approach 1:
The patent segments EAS messages by type (weather alerts, AMBER alerts, government alerts, geophysical alerts) and applies selective delivery based on subscriber preferences. The system divides the broadcast stream into different alert categories and filters them according to user-configured criteria, allowing subscribers to receive only relevant alert types while maintaining comprehensive coverage for those who need all alerts.
Solution Approach 2:
The patent implements local quality by allowing each subscriber to have customized alert reception parameters. Subscribers can individually configure which alert types they want to receive, what time periods they are interested in, and what actions to take. This creates personalized alert delivery quality for each subscriber while maintaining the same broadcast infrastructure for all users.
2Quantity of substance
If all alert types are delivered to subscribers, then comprehensive information is provided, but subscriber preference customization is limited
Solution Approach 1:
The patent implements dynamics by enabling subscribers to dynamically configure their alert preferences in real-time. Subscribers can modify their selected alert types, time periods, and action preferences through the user interface, and these changes are immediately applied to their alert reception. The system dynamically adjusts delivery parameters based on user input while maintaining the ability to provide comprehensive alert information when needed.
3Device complexity
If EAS alerts are processed uniformly, then system simplicity is maintained, but processing flexibility and user control are reduced
Solution Approach 1:
The patent implements self-service by enabling subscribers to independently configure their own alert preferences without requiring complex system intervention. Users can select their preferred alert types, time periods, and actions through an intuitive interface, and the system automatically applies these preferences to their personal alert processing. This maintains relative system simplicity while providing users with direct control over their alert reception.
Data Source
AI summary
Broadcast emergency alert messages are selectively processed in accordance with various aspects of the alerted event, the alert message, and/or user preferences. In an example configuration, a mobile device is preconfigured with instructions defining how to process various types of emergency alert messages. A received broadcast emergency alert message is analyzed to determine various characteristics pertaining to the message, such as alert type, alert subtype, likelihood of alert occurrence, alert severity, receipt time, geographic extent of the alert area, originator of the alert message, a time when the alert message was originated. The message is processed in accordance with the preconfigured instructions and the characteristics pertaining to the message. A user of the mobile device can tailor the type of EAS alerts to be received, the time period, or periods, during which EAS alerts can be received, and actions to be taken with respect to received alerts.
