Progressive Area Expansion for Faster Emergency Service Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emergency response systems, such as the 911 system, often suffer from inefficiencies and delays due to the need to route calls through multiple regional dispatch centers, leading to prolonged response times in critical situations.
Innovation Solution
A dynamic emergency response system that utilizes user devices, network access nodes, network infrastructure, and satellites to progressively expand the search area for the nearest emergency service, incorporating AI to analyze user dialogue for signs of distress and ensure timely connection to the appropriate services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If calls are routed through multiple regional dispatch centers, then call routing coverage is ensured, but response time increases
Solution Approach 1:
The patent extracts the call routing function from the traditional multi-layer dispatch center hierarchy and relocates it to the network access node (base station). This allows the system to bypass intermediate dispatch centers and directly connect emergency callers to the nearest emergency service, significantly reducing response time while maintaining routing accuracy through localized decision-making at the access node
Solution Approach 2:
The patent introduces a new spatial dimension for call routing by using geographic location data and network access node positioning instead of traditional hierarchical dispatch center routing. This dimensional shift enables direct geometric routing from caller to nearest emergency service based on physical proximity rather than organizational hierarchy
2Measurement precision
If search area is limited to ensure precision, then emergency service identification accuracy improves, but coverage area is restricted
Solution Approach 1:
The patent implements a dynamic search area mechanism where the search radius expands progressively from a small initial zone around the caller's location. The system starts with a precise local search and automatically expands the coverage area if no emergency services are found, thereby maintaining both initial precision and eventual comprehensive coverage
Solution Approach 2:
The system performs preliminary action by first searching within a small, precise radius around the caller's location to quickly identify nearby emergency services. This initial focused search maintains high precision, and only if necessary does the system subsequently expand the search area to ensure complete coverage
Data Source
AI summary
The technology provides a system that allows for a first user (e.g., counselor) located far away from a second user (e.g., at-risk user) to easily contact the second user. The first user can provide an emergency response including an emergency service nearest to the location of the second user. The system searches for the nearest emergency service based on a selected area of a predetermined zone where the second user is located. Where there are no emergency services located in the selected area, the system successively searches expanded areas corresponding to predetermined zones for an emergence service until there is an emergency response. The system automatically updates the selected area for successively expanded predetermined zones for each instance where no emergency response is received in response to the search request.
