Emergency Call Data Relay for Multi-Tenant PSAPs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multi-tenant 9-1-1 call handling solutions require on-site infrastructure and individual connections at each public safety answering point (PSAP) for emergency call data processing, which is inefficient and increases the complexity of network infrastructure.
Innovation Solution
A system that captures emergency call data at a central CPE host and transmits it to a cloud-based server for processing, eliminating the need for on-site devices and individual connections at PSAPs, using a frame buffer, frame handler, and data gateway to route and process call data efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If on-site infrastructure and individual connections are installed at each PSAP for emergency call data processing, then each PSAP can independently process call data, but the network infrastructure complexity and installation time increase significantly
Solution Approach 1:
The patent consolidates call data processing functionality into a centralized cloud-based platform, merging previously distributed on-site infrastructure at multiple PSAPs into a single remote location. This eliminates the need for individual connections and on-site devices at each PSAP, reducing network infrastructure complexity while maintaining call data processing capabilities through centralized access.
Solution Approach 2:
The patent introduces a centralized relay agent or gateway as an intermediary between the CPE host and cloud-based CAD systems. This intermediary consolidates the connection points, allowing multiple PSAPs to access call data through a single centralized interface rather than requiring individual direct connections to each PSAP, thereby reducing overall infrastructure complexity.
2Reliability
If on-site devices are installed at each PSAP to capture emergency call data, then call data can be captured locally, but the installation process becomes time-consuming and inefficient
Solution Approach 1:
The patent extracts the call data capture and processing functionality from on-site PSAP locations and relocates it to a centralized cloud-based platform. By taking out the data capture capability from multiple distributed locations and consolidating it centrally, the system eliminates the need for lengthy installation processes at each PSAP while maintaining the essential function of emergency call data capture and access.
3Ease of operation
If individual ALI or CAD spill connections are provided to each PSAP, then each PSAP has direct access to call data, but the network infrastructure and cost increase
Solution Approach 1:
The patent creates a universal centralized access point that serves multiple PSAPs simultaneously. Instead of providing individual dedicated connections to each PSAP, a single centralized cloud-based platform provides multi-functional access to call data for numerous PSAPs, reducing the total number of connections required while maintaining direct access capabilities for all users through the unified platform.
Data Source
AI summary
An emergency call data relay includes a frame buffer and a frame handler. The frame buffer stores data frames received from a central system (e.g., a central CPE host). The data frames include call data associated with an emergency call being handled at a remote system (e.g., a PSAP) connected to the central system. The frame handler receives a data frame from the frame buffer, identifies a remote system handling the emergency call associated with the call data based on a network address in the data frame, extracts the call data from the data frame, and generates an output packet for a data gateway. The output packet has a header indicating a particular data gateway profile associated with the identified remote system handling the emergency call.
