CAD Incident Data Transfer Between PSAP Stations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cloud-based emergency call handling systems cannot automatically transfer corresponding computer aided dispatch (CAD) incident data when an emergency call is transferred between users at a public safety answering point (PSAP), requiring manual retrieval by the receiving user.
Innovation Solution
A system and method for automatically transferring CAD incident data between PSAP station computing devices via a cloud-based ECH server, where a first PSAP station sends CAD data to a message queue at the CAD server upon successful call transfer, allowing the second PSAP station to receive the data automatically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If cloud-based ECH server handles emergency call transfers automatically, then call transfer efficiency is improved, but CAD incident data transfer capability deteriorates (remains manual)
Solution Approach 1:
The patent introduces a message queue as an intermediary component between the ECH server and CAD server. When a call transfer occurs, the ECH server publishes a transfer event to the message queue, which then automatically triggers the CAD server to transfer the associated incident data to the receiving PSAP station. This intermediary mechanism decouples the call transfer process from the data transfer process, enabling automated CAD data synchronization without modifying the core ECH or CAD systems.
2Device complexity
If manual retrieval of CAD incident data is required after call transfer, then system complexity is reduced, but operational time increases
Solution Approach 1:
The system implements self-service by enabling the CAD server to automatically detect call transfer events through the message queue and autonomously transfer the corresponding incident data to the receiving PSAP station. The receiving station simply subscribes to the message queue and automatically receives the transferred data without requiring manual retrieval actions. This self-service mechanism eliminates the need for users to manually search for and transfer CAD data, significantly reducing operational time while maintaining manageable system complexity through event-driven architecture.

AI summary
Systems, methods, and non-transitory computer-readable mediums for transferring computer aided dispatch (CAD) incident data between public safety answering point (PSAP) station computing devices as a result of a detected successful call transfer at an emergency call handling (ECH) server. In one example, a first PSAP station computing device is configured to receive a call from the ECH server, CAD incident data associated with the call, and a request to transfer the call. The first PSAP station computing device is also configured to send a request to the ECH server to transfer the call. The first PSAP station computing device is also configured to receive an acknowledgement from the ECH server of a successful call transfer. The first PSAP station computing device is also configured to send a request to a message queue to provide the CAD incident data to the PSAP station computing device that received the transferred call.
