Disaster Notification Prioritization for Safety Registration Surges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The registration of large amounts of safety information by numerous users in response to server notifications during disasters leads to an increased load on the server.
Innovation Solution
A notification system that prioritizes transmitting notifications to terminals that generate abandoned calls after a disaster, indicating the start of safety information reception, thereby reducing the load on the server by managing the registration process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the server outputs notifications to a large number of users to inform them of safety information registration, then user awareness and participation are improved, but the server load increases significantly
Solution Approach 1:
The system performs preliminary actions by detecting abandoned calls before the disaster occurs and storing this information in advance. When the disaster happens, the system uses this pre-detected information to prioritize notifications, thereby reducing server load while maintaining notification effectiveness.
Solution Approach 2:
The system applies local quality by differentiating treatment for different users based on their call behavior patterns. Users who generate abandoned calls receive prioritized notifications, while other users are notified according to normal processing, creating localized differentiation in notification handling.
2Quantity of substance
If the server processes safety information registration from all users simultaneously, then complete information collection is achieved, but processing time and server resources increase
Solution Approach 1:
The system segments the user base into different groups based on abandoned call detection. By dividing users into those who generate abandoned calls and those who do not, the system can process registration requests in prioritized batches, reducing overall processing time while maintaining complete information collection.
Solution Approach 2:
The system performs preliminary detection and classification of users based on call patterns before the registration surge. This pre-sorting allows the server to process registration requests more efficiently by handling high-priority users first, thereby reducing total processing time.
3Productivity
If the system notifies all registered users about safety information registration, then user engagement is maximized, but the number of notification processing tasks increases
Solution Approach 1:
The system applies local quality by treating different user segments differently based on their communication patterns. Users who generate abandoned calls receive prioritized notification treatment, while other users are handled through standard processing, thereby maintaining engagement while managing processing complexity.
Solution Approach 2:
The system uses abandoned call detection as a self-service mechanism to automatically identify users who need prioritized notification. This self-identification reduces the need for manual user classification and simplifies notification processing complexity.

AI summary
In order to suppress any increase in the load of a server that accepts safety information, this notification device comprises an acquisition means for acquiring an occurrence timing at which a disaster occurs, a specification means for specifying a terminal at which abandoned calls occurred at and after the occurrence timing, and a transmission means for transmitting a notification that indicates that the acceptance means has begun to accept safety information to the specified terminal earlier than to other terminals among a plurality of terminals.
