Emergency Context Retrieval for First Responder Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current emergency call systems lack the capability to seamlessly obtain and transfer contextual information to first responders, making it time-consuming and error-prone, which can compromise the safety of both callers and responders.
Innovation Solution
A customer information system that stores context information associated with caller identifications, allowing the carrier network to automatically provide relevant context information to responder devices during emergency calls, using a key correlation mechanism to ensure accurate and timely data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dispatchers manually obtain and relay context information from callers, then contextual information can be provided to responders, but the process becomes time-consuming and error-prone
Solution Approach 1:
The system enables self-service by automatically retrieving context information from databases using the caller's identification data. The carrier network initiates queries to customer information systems without human intervention, allowing the system to serve itself in obtaining and transferring contextual data about the caller, their location, and emergency details.
Solution Approach 2:
The manual mechanical process of dispatchers verbally obtaining and relaying information is replaced with an automated electronic information system. The carrier network automatically queries databases, retrieves context information, and transfers it to responder devices through digital communication channels, eliminating the need for human-to-human information transfer.
2Reliability
If dispatchers manually obtain context information, then information can be relayed to responders, but dispatcher efficiency decreases and they cannot assist on other calls
Solution Approach 1:
The automated system performs the information gathering function independently, allowing dispatchers to remain available for other tasks. The carrier network automatically queries customer information systems and retrieves complete context information without requiring dispatcher involvement in the information gathering process.
Solution Approach 2:
An automated information system acts as an intermediary between the caller identification and the responder devices. The carrier network serves as a mediator that automatically queries databases using caller data and retrieves contextual information, eliminating the need for dispatchers to manually bridge this information gap.
3Measurement precision
If location determination systems are used to identify caller location, then location information can be provided to responders, but no other contextual information is automatically transferred
Solution Approach 1:
The automated information retrieval system performs multiple functions simultaneously: it retrieves location information, medical emergency details, caller history, and other contextual data from various databases. The carrier network queries customer information systems comprehensively, making the system universal in its ability to gather diverse types of contextual information beyond just location.
Solution Approach 2:
The context information is segmented into multiple categories including location data, medical emergency information, caller identification details, and historical data. The system queries different database segments separately and aggregates them into a comprehensive context information package that is transferred to responder devices.
Data Source
AI summary
A communication network comprises a public safety answering point, a responder device, and a customer information system. The public safety answering point receives a call from a caller and signaling for the call. The signaling indicates a key associated with the call. The public safety answering point transfers dispatch information that identifies the key to the responder device. The responder device receives the dispatch information and generates and transmits a context request that indicates the key. The responder device receives a context response that includes a context information. The customer information system receives the context request, processes the context request to select the context information from a plurality of context information based on the key, and transfers the context response.
