Emergency Tracking Session Triggering for Post-Call Data

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Emergency support systems typically only gather information during an emergency call and do not receive additional data that becomes available after the call has ended, limiting the information available to emergency service providers.

Innovation Solution

An emergency call server determines if a device should be tracked based on an emergency condition and sends a triggering message to initiate a tracking session, allowing the device to periodically collect and send tracking session data to servers, separate from the emergency call session, even in reduced-power mode.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If continuous tracking is implemented after emergency call ends, then information availability to emergency services is improved, but device battery consumption increases

Engineering Contradiction:

Improveinformation availabilityVSAvoidbattery consumption

Core Design Contradiction:

Loss of informationVSUse of energy by moving object

Solution Approach 1:

The system implements periodic tracking sessions where the device collects and transmits location data at predetermined intervals rather than continuously. The emergency call server sends triggering messages to initiate tracking sessions, and the device periodically wakes up to collect location information and send it to the server, allowing the device to enter low-power states between sessions.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The tracking system dynamically adjusts its operation based on emergency conditions. The emergency call server determines whether tracking should be activated based on the emergency situation, and the device transitions between active tracking modes and low-power states, adapting its behavior to the specific emergency context and battery status.

Inventive Principle:

Principle #15Dynamics

2Duration of action of moving object

If tracking session is established separate from emergency call session, then data collection continuity is improved, but system complexity increases

Engineering Contradiction:

Improvedata collection continuityVSAvoidsystem complexity

Core Design Contradiction:

Duration of action of moving objectVSDevice complexity

Solution Approach 1:

The system segments the emergency response communication into two distinct sessions: an emergency call session for immediate emergency handling, and a separate tracking session for continuous location monitoring. This segmentation allows each session to operate independently with its own protocol and timing, enabling continuous data collection without complicating the emergency call infrastructure.

Inventive Principle:

Principle #1Segmentation

AI summary

Disclosed are methods, systems, devices, servers, apparatus, computer-/processor-readable media, and other implementations, including a method that includes receiving by an emergency call server an indication of an emergency condition at a device, determining whether the device is to be tracked based, at least in part, on the indication of the emergency condition, and transmitting a triggering message from the emergency call server, in response to a determination that the device is to be tracked, to trigger at the device a tracking session to cause the device to periodically collect and send tracking session data to one or more servers. The tracking session, established between the device and the one or more servers, is separate from an emergency call session established between the device and the emergency call server.
