Solution Overview

Problem

Conventional 911 call systems lack robustness and scalability, failing to alert or involve additional parties that could assist in emergency situations, and provide no recourse for failed 911 call attempts.

Innovation Solution

A computing system determines if a user profile associated with a caller or their originating telephone number contains registered third parties on a 911 call notification list. If present, the system sends messages to these third parties, allowing them to be notified, bridge into the 911 call, or access call records and recordings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional 911 call systems are used, then the system structure remains simple, but the system lacks robustness and cannot involve additional parties to assist in emergency situations

Engineering Contradiction:
Improverobustness of 911 call systemVSAvoidsystem structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system segments the 911 call flow into distinct phases: pre-call registration of third parties, call detection, notification delivery, and optional conference bridge establishment. This segmentation allows the system to handle complex scenarios through modular components rather than a monolithic structure, improving robustness while maintaining manageable complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary actions by pre-registering third parties with their contact information and preferences before an emergency occurs. This advance preparation enables the system to quickly notify relevant parties when a 911 call is detected, enhancing reliability without requiring complex real-time decision-making during the emergency.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If conventional 911 call systems are used, then the system operates simply, but it provides no recourse for failed call attempts

Engineering Contradiction:
Improverecourse for failed callsVSAvoidcall handling complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system implements feedback mechanisms that detect when a 911 call attempt fails and automatically trigger alternative actions, such as notifying registered third parties or attempting reconnection. This feedback loop ensures that failed calls are not simply ignored but are actively managed, improving reliability while adding structured complexity to the call handling process.

Inventive Principle:
Principle #23Feedback

3Productivity

If the system notifies registered third parties of 911 calls, then emergency response is improved, but the system complexity increases

Engineering Contradiction:
Improveemergency response efficiencyVSAvoidnotification system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The notification system is designed with multi-functionality, serving multiple purposes: informing third parties of call status, providing them with call details, enabling optional conference bridge participation, and allowing post-call access to recordings. This universal approach consolidates multiple functions into a single system component, improving emergency response efficiency without proportionally increasing complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Ease of operation

If administrators can access call records and recordings, then call management is improved, but system complexity increases

Engineering Contradiction:
Improvecall management capabilityVSAvoidrecord storage and access complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system introduces an intermediary layer between the call processing system and administrators, providing a dedicated interface for accessing call records and recordings. This intermediary structure organizes and presents complex call data in a manageable format, improving ease of operation while isolating the complexity of record storage and retrieval from the user interface.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Novel tools and techniques are provided for implementing enhanced 911 call functionalities. In various embodiments, in response to receiving a 911 call request from a caller using a calling device associated with an originating telephone number (“TN”), a computing system may determine whether a user profile associated with the caller and/or the originating TN contains registered third parties on a 911 call notification list. Based on a determination that the user profile contains at least one registered third party on the 911 call notification list associated with the caller and/or the originating TN, the computing system may send a message to each of the at least one registered third party indicating that the caller has called 911, and/or may establish a listen—in only bridged connection, a full bridge connection, or a shared communication to the 911 call for each registered third party.
