ALI Database Text Field for Emergency Information Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current emergency response systems, particularly 911 systems, face limitations in conveying alphanumeric information and multimedia data, leading to potential omissions and mistakes during emergency situations.
Innovation Solution
The method involves updating the automatic location identification (ALI) database with alphanumeric characters indicative of the nature of the emergency in a content-specified text field, allowing for the display of this information on PSAP terminals and enabling access to additional emergency services information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If legacy PSAP terminals with fixed interface are used, then system compatibility and ease of operation are maintained, but information completeness and measurement precision deteriorate due to limited display capabilities
Solution Approach 1:
The solution segments information transmission by using separate data fields in the ALI database: one field for traditional location data and another text field for emergency nature description. This allows legacy terminals to display location information while new terminals can access both location and emergency details, resolving the contradiction between information completeness and device compatibility.
Solution Approach 2:
The ALI database text field acts as an intermediary that carries emergency nature information from the communication device to the PSAP terminal. This intermediary structure enables information transmission without requiring changes to the terminal interface itself, thus maintaining ease of operation while improving information completeness.
2Adaptability or versatility
If NG911 systems with full computing functionality are deployed, then information completeness and adaptability improve, but device complexity and implementation cost increase significantly
Solution Approach 1:
The ALI database text field is designed to serve multiple functions: it can store location information, emergency nature descriptions, and other relevant data. This universal structure allows both legacy and next-generation terminals to access appropriate information without requiring complex terminal upgrades, thus improving adaptability while controlling device complexity.
Solution Approach 2:
The solution implements a partial upgrade approach by enhancing the ALI database structure rather than requiring complete terminal replacement. Legacy terminals continue to function with basic display capabilities while newer terminals can leverage the enhanced database structure for advanced features, allowing gradual adoption without forcing full system complexity on all devices.
3Measurement precision
If information is conveyed orally by the caller, then ease of operation is maintained, but information accuracy and reliability deteriorate due to omissions and mistakes
Solution Approach 1:
The system performs preliminary action by automatically capturing and storing emergency nature information in the ALI database text field before the call is processed by the PSAP operator. This pre-prepared information reduces the burden on the caller and eliminates oral transmission errors, thus improving accuracy while maintaining ease of operation through automated data capture.
Solution Approach 2:
The PSAP terminal displays the emergency nature information retrieved from the ALI database, providing feedback to the operator about the call details. This automated feedback mechanism ensures accurate information transmission without requiring the caller to verbally convey all details, thus improving measurement precision while keeping the operation simple for both caller and operator.
Data Source
AI summary
An improved emergency response method and system are shown and described. A content-specified text field-such as a caller name field—an ALI database record for a communication device is updated to include information about a person experiencing an emergency and the emergency. A PSAP receiving an emergency services call from the communication device receives the caller name field on a terminal display and is thus informed about the emergency via a alphanumeric character communication rather than orally. A particular emergency may be assigned a code that is put in the caller name field. A PSAP operator receiving the emergency services call may then enter the code into an emergency services web interface to retrieve information about the emergency including service provider credentials, the person's medical condition, the person's medical records, real time physiologic data, treatment facility names, treatment facility types, a location of the emergency, a level of care, a videoconference web link, on-site personnel names, disaster information, and hazard information. The code can be transmitted to first responders and downstream medical professionals to enhance their ability to deliver emergency services. The system and method provide a means for legacy PSAPs to receive the benefits of Next Generation 911 systems without the infrastructure changes that would otherwise be required.
