Emergency Alert Gateway Media Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current emergency alert systems, such as the Commercial Mobile Alert System (CMAS), face challenges in efficiently delivering diverse alert types (text, audio, video, multimedia) to targeted mobile device users, particularly in updating geo-targeted areas and ensuring compatibility with varying mobile device capabilities.
Innovation Solution
A system and method for sending emergency alerts that determine the type of message (text, audio, video, multimedia) and validate availability, broadcasting the appropriate message portions while geo-targeting and adapting to mobile device receive capabilities, with the option to modify and update alert messages and their components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If emergency alerts include multiple media types (audio, video, multimedia), then the information completeness and user experience are improved, but the system complexity and storage requirements increase
Solution Approach 1:
The alert message is divided into separate components: text message, audio portion, video portion, and multimedia portions. Each component is stored separately in the database and can be independently managed, retrieved, and broadcast based on device capabilities and availability, reducing system complexity while maintaining information completeness
Solution Approach 2:
All alert message components (text, audio, video, multimedia) are pre-stored in the database before broadcasting. This allows the system to quickly retrieve and broadcast appropriate components based on device capabilities without complex real-time processing, simplifying the broadcasting mechanism while ensuring complete information delivery
2Reliability
If the system validates and checks availability of stored alert portions, then the reliability of message delivery is improved, but the processing time and operational complexity increase
Solution Approach 1:
The system performs validation and availability checks of stored alert portions in advance, before the actual broadcasting occurs. This preliminary verification ensures that only available and valid message components are selected for broadcast, maintaining high reliability while keeping the operational process simple through automated pre-checks
3Loss of time
If the system broadcasts to updated geo-targeted areas, then the relevance and timeliness of alerts are improved, but the network load and broadcasting complexity increase
Solution Approach 1:
The geo-targeted area parameters are made dynamic and can be updated without requiring system reconfiguration. The system accepts updated geographic parameters and automatically adjusts the broadcasting scope to cover both previous and new areas, ensuring timely alerts while simplifying operations through automated dynamic adaptation
4Adaptability or versatility
If the system adapts alert messages to mobile device receive capabilities, then the compatibility and user experience are improved, but the processing requirements and system complexity increase
Solution Approach 1:
The system tailors the alert message composition to each mobile device's specific capabilities. Based on device receive capabilities, the system selectively broadcasts appropriate message components (text only, or text with audio, video, or multimedia), ensuring optimal compatibility while managing processing complexity through capability-based differentiation
Data Source
AI summary
An emergency alert gateway configured for receiving an emergency alert message wherein the alert message includes a text message and one of an audio message, a video message, an audio-video message and a multi-media message; storing an audio, video or multimedia portion of the alert message to form a first stored portion and for determining a subscriber base to receive the alert message. There is a database in communication with the alert gateway and an emergency alert server configured to broadcast the alert message to the subscriber base, and if the first stored portion of the alert message is not available, then broadcasting only the text message as the alert message.
