Wireless Emergency Alert Feedback for Broadcast Reliability Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless emergency alert systems lack an automated arrangement for measuring the reliability, delay, and accuracy of emergency message broadcasts, as they cannot receive and process confirmatory messages from mobile wireless devices effectively.
Innovation Solution
A system and method for generating and accumulating alert response messages from user equipment, including a data payload with location and handling results, processed by a web server to assess the effectiveness of emergency alert message distribution, using enhanced functionality in mobile devices and network infrastructure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If emergency alert messages are broadcast to mobile wireless devices, then public safety information is disseminated, but there is no automated arrangement for measuring the reliability and effectiveness of such broadcasts
Solution Approach 1:
The patent implements a feedback mechanism where mobile wireless devices send alert response messages back to the network infrastructure after receiving emergency alert messages. These response messages contain confirmation data about successful reception, enabling automated measurement of broadcast reliability and effectiveness through accumulation and processing of the response messages.
2Measurement precision
If the network infrastructure receives and processes confirmatory messages from mobile devices, then broadcast effectiveness can be measured, but the system complexity increases
Solution Approach 1:
The patent enables mobile wireless devices to automatically generate and transmit alert response messages without requiring complex manual intervention. The devices self-report their reception status by including alert identification and handling results in the response messages, allowing the network infrastructure to measure effectiveness through relatively simple accumulation and processing operations.
Data Source
AI summary
A method and system are described for providing an accumulated set of alert response message content arising from disseminating an emergency alert message to user equipment via mobile wireless network infrastructure. An emergency alert is received that is issued by an emergency alert system. The emergency alert includes: an emergency description, and a target geographic area. An emergency alert message, corresponding to the emergency alert, is disseminated to user equipment via mobile wireless infrastructure. A set of alert response messages issued by user equipment responding to the emergency alert message are accumulated. Instances of the alert response messages provide: an emergency alert identification, a user equipment location, and an alert message handling result. An aggregated result is presented that indicates user equipment-issued alert response messages.
