Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Emergency networks struggle to accurately determine the location of mobile devices and manage diverse emergency communications from non-homogeneous sources, particularly with the advent of wireless communication technologies and over-the-top voice-over-Internet-protocol (VoIP) communications, leading to inefficiencies in dispatching emergency responders.

Innovation Solution

An apparatus and method for establishing a data connection between a mobile device and an emergency responder device, utilizing a cloud server to send emergency data, including location and medical information, and enabling a direct communication link through a web socket connection or IP-based call back, facilitated by an emergency network entity and a software-as-a-service application.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If emergency networks use traditional PSTN and landline telephone systems, then determining caller location is straightforward, but the system cannot handle mobile devices and VoIP communications

Engineering Contradiction:

Improvecompatibility with diverse communication sourcesVSAvoidlocation determination accuracy

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The system segments the emergency communication architecture into multiple independent components: traditional PSTN interfaces, mobile device interfaces, VoIP application interfaces, and a central emergency network entity. Each segment handles specific communication types independently, allowing the system to accommodate diverse sources without compromising location determination accuracy for any particular type.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The emergency network entity is designed as a universal platform that can receive and process emergency communications from multiple sources including landline telephones, mobile devices, and VoIP applications through a single integrated interface. This multi-functional design enables the system to handle heterogeneous communication sources while maintaining consistent location determination capabilities across all types.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If emergency networks adopt wireless communication and mobile Internet connectivity, then the system can receive communications from mobile devices and VoIP applications, but determining caller location becomes complex

Engineering Contradiction:

Improveability to receive emergency communications from mobile devices and VoIPVSAvoidcomplexity of location determination system

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The emergency network entity serves as an intermediary between diverse communication sources (mobile devices, VoIP applications) and the location determination system. It receives emergency communications from various sources, extracts relevant location information using standardized protocols, and presents this information to responders in a unified format, thereby simplifying the overall system architecture despite handling multiple communication types.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system employs parameter changes by utilizing different location determination methods appropriate for each communication type: traditional telephone number-based location for PSTN, cell tower triangulation and GPS for mobile devices, and IP address-based location for VoIP. The emergency network entity dynamically selects and applies the appropriate location parameters based on the communication source type.

Inventive Principle:

Principle #35Parameter changes

3Loss of information

If emergency networks process communications from multiple non-homogeneous sources, then the system receives more comprehensive emergency data, but dispatch efficiency decreases

Engineering Contradiction:

Improvecompleteness of emergency data receivedVSAvoidemergency responder dispatch efficiency

Core Design Contradiction:

Loss of informationVSProductivity

Solution Approach 1:

The emergency network entity performs preliminary actions by automatically processing and standardizing location and communication data from diverse sources before presenting it to emergency responders. It pre-formats information, determines optimal responder assignments based on location and emergency type, and prepares dispatch recommendations in advance, thereby maintaining high dispatch efficiency despite receiving comprehensive data from multiple sources.

AI summary

A disclosed method includes: sending emergency data from a cloud server to an emergency network entity, the emergency data received by the cloud server from a mobile device; sending a link to an emergency responder device located in proximity to a location of the mobile device in response to the emergency network entity receiving the emergency data; and establishing a data connection between the cloud server and the emergency responder device in response to selection input from the emergency responder device selecting the link. The method may further include establishing a data connection between the mobile device and the emergency responder device in response to selection input from the emergency responder device selecting the link.
