Abandoned Emergency Call Alerting Without Exposing the Caller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Emergency call centers struggle to distinguish between real emergencies and accidental calls, leading to potential dangers for callers who may be in distress, as dispatchers may expose them by calling back or ignore calls that could indicate severe situations.
Innovation Solution
A method and system that analyze signal data from abandoned calls to determine if the caller is in danger, using position data and proximity to other devices to send silent or audible alerts without revealing the caller's location, ensuring assistance is sent safely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dispatchers call back abandoned calls to verify the situation, then they can distinguish between real emergencies and false alarms, but they may expose the caller in greater danger
Solution Approach 1:
The system uses automated analysis of signal data, device movement patterns, and environmental information as an intermediary to verify emergency situations without requiring direct dispatcher-caller communication. This mediator layer filters and analyzes data to determine whether a callback is safe, thus resolving the contradiction between verification accuracy and caller safety
Solution Approach 2:
The abandoned call device itself provides verification data through its sensors (accelerometer, pressure sensor, GPS) and communication capabilities. The device's movement patterns, altitude changes, and proximity to other devices serve as self-generated evidence of the emergency situation, eliminating the need for dispatcher intervention that could expose the caller
2Object-affected harmful factors
If dispatchers ignore abandoned calls to avoid exposing callers, then caller safety is protected, but real emergencies may be missed
Solution Approach 1:
The manual mechanical process of dispatcher review and callback is replaced with an automated electronic system that continuously monitors signal data, device movement, and environmental information. This electronic substitution enables constant surveillance of abandoned calls without human intervention, maintaining caller protection while ensuring real emergencies are detected through automated analysis
3Loss of information
If the system collects data from the abandoned call device and nearby devices, then it can analyze whether the victim is hiding or in danger, but it increases the complexity of the system
Solution Approach 1:
The system leverages existing multi-functional smartphone sensors (accelerometer, pressure sensor, GPS, microphone) that already serve multiple purposes. These universal components provide emergency verification data without requiring dedicated emergency equipment, thus reducing system complexity while maintaining comprehensive information collection capabilities
Solution Approach 2:
The system merges data from multiple sources (abandoned call device sensors, nearby device signals, environmental information) into a unified analysis framework. By combining these diverse data streams through a centralized evaluation process, the system achieves comprehensive situational awareness without the complexity of separate analysis systems for each data type

AI summary
The present invention relates to a method and a system for silent and non-exposing alerting of previously abandoned calls. The method and the system handle callbacks in in emergency systems such as Next Generation NG9-1-1 or NG1-1-2 systems with the main focus to avoid exposing people in trouble to a dangerous situation. When abandoned call is detected, verify moving of the calling device and mark as potential victim if not moving. Detect difference in altitude within a time interval of the device and if not large identify other devices in proximity. Send an alert to the proximate devices if it is moving or far enough else send silent alert to the abandoned call device.
