Emergency Gateway Adapting PSAP Message Formats
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for delivering emergency event messages lack efficiency in identifying and formatting messages for specific Public Safety Answering Points (PSAPs), often requiring proprietary protocols and hardware, which limits flexibility and scalability.
Innovation Solution
A gateway system that receives emergency event messages, queries a Location-to-Service Translation (LoST) server to identify the appropriate PSAP customer premise equipment (CPE), determines the necessary message format, and reformats the message for delivery, allowing for real-time adaptation to different PSAP protocols and network conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If proprietary protocols and hardware are used for each PSAP type, then message delivery reliability is improved, but device complexity and scalability worsen
Solution Approach 1:
The gateway is designed as a universal device that can handle multiple PSAP types through a single unified interface. It receives emergency messages in one standardized format and automatically adapts to different PSAP requirements, eliminating the need for separate proprietary hardware for each PSAP type while maintaining reliable message delivery.
Solution Approach 2:
The gateway acts as an intermediary between the emergency message source and various PSAP systems. It receives messages in a standardized format, translates them into PSAP-specific formats, and delivers them appropriately, thereby maintaining reliability without requiring direct proprietary connections between all systems.
2Adaptability or versatility
If multiple PSAP-specific formats are supported, then adaptability is improved, but device complexity increases
Solution Approach 1:
The gateway handles format adaptability by changing message parameters dynamically. It receives messages in a standardized format and modifies parameters such as message structure, encoding, and addressing to match the specific requirements of different PSAP systems, achieving versatility without manual configuration complexity.
Solution Approach 2:
The gateway performs preliminary format determination by identifying the target PSAP type before message transmission. It queries the LoST server to obtain PSAP information including required formats in advance, allowing the gateway to prepare and format messages appropriately without adding complexity during the actual message delivery process.
3Manufacturing precision
If manual configuration is required for each PSAP, then message formatting precision is improved, but productivity and ease of operation worsen
Solution Approach 1:
The gateway performs self-configuration by automatically querying the LoST server to obtain PSAP information including required message formats. It determines the appropriate format autonomously based on the target PSAP identifier, eliminating the need for manual configuration while maintaining precise formatting through programmatically obtained specifications.
Solution Approach 2:
The gateway uses feedback from the LoST server to automatically adjust message formatting. The server provides PSAP-specific information including required formats, and the gateway incorporates this feedback to generate appropriately formatted messages, ensuring precision without manual intervention and improving operational efficiency.
Data Source
AI summary
A gateway can be configured to receive an emergency event message in a predefined format via a network. The emergency event message can characterize a location and a nature of an emergency event. The gateway can also be configured to identify a particular Public Safety Answering Point (PSAP) customer premise equipment (CPE) to service the emergency event. The gateway can further be configured determine a format of messages employable by the particular PSAP. The gateway can still further be configured to provide the particular PSAP CPE with an output message in the format employable by the particular PSAP CPE. The output message can characterize the nature and the location of the emergency event.
