PSAP Video Call Merging for Emergency Bandwidth Overload
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
PSAPs face resource overloads due to multiple emergency calls, especially video streams with varying codecs, leading to inefficient bandwidth usage during simultaneous handling of emergency incidents.
Innovation Solution
A method utilizing a Machine Learning (ML) classifier to identify similar video streams at a PSAP, selecting the most resource-efficient stream, and allowing call takers to confirm and replicate it across multiple devices, converting less efficient streams to audio if necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple video calls with different codecs are received simultaneously at the PSAP, then the emergency incident can be reported from multiple sources, but the bandwidth consumption and system load increase significantly
Solution Approach 1:
The patent merges multiple video calls reporting the same emergency incident by identifying similar calls through ML classification and selecting one representative video stream to be distributed to all relevant call takers. This combining approach maintains reliable incident reporting through multiple caller sources while significantly reducing bandwidth consumption by eliminating redundant video stream transmissions.
2Loss of information
If all received video calls are transmitted to call takers, then complete information is provided, but the PSAP resources become overloaded
Solution Approach 1:
The patent extracts and identifies the essential representative video stream from among multiple similar calls using ML classification and comparison. By selecting one optimal video stream that captures the emergency incident adequately, the system provides complete emergency information to call takers while removing redundant video streams that would otherwise overload PSAP resources.
3Ease of operation
If video streams from multiple callers are distributed to all call takers, then each call taker has full information, but the bandwidth usage becomes inefficient
Solution Approach 1:
The patent merges the information access experience for all call takers by selecting a single representative video stream that is then distributed to all of them. This approach ensures that every call taker has access to complete emergency incident information while avoiding the inefficient bandwidth consumption that would result from distributing multiple redundant video streams to each call taker.

AI summary
The present invention relates to a computer-implemented method of processing an emergency incident reported to a PSAP (1) by a plurality of callers (2, 2', 2", 2'''), the method comprising the steps of: receiving, at the PSAP (1), a video call (4, 4', 4", 4"') for reporting an emergency incident at a specified location; checking, at the PSAP (1), if further video calls (4, 4', 4", 4"') have been received from the same specified location within a predetermined time period, and if it is determined that there are further video calls (4, 4', 4", 4"') that have been received at the PSAP (1) for the same specified location within the predetermined time period, feeding at least a part of the video call and the further video calls to a ML classifier unit (5), identifying, at the ML classifier unit (5), if there are similarities between the video call and the further video calls, and if it is determined that there exists similarity between the video call and at least one further video call, determining which one of the video calls that have been determined to be similar uses less resources, in particular, less bandwidth. Further, the present invention relates to an emergency communication network, comprising at least one PSAP (1) for handling at least one emergency incident according to the computer-implemented method for processing an emergency incident.
