Solution Overview

Problem

Traditional communication networks face challenges in accurately identifying the physical location of a communication device originating an emergency call, especially in mobile or VoIP environments, leading to difficulties in providing timely and effective emergency services due to resistance in sharing call back information between service providers.

Innovation Solution

A system and method that utilize a location database to maintain and provide the physical location of a communication device, allowing emergency service answering systems to access this information while concealing it from the terminating network, using a key to request and retrieve the call back number and location from an ALI database, and employing a communication device stability module to determine and update the location status of mobile devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If telecommunication networks associate telephone numbers with telecommunication devices or registered users rather than physical locations, then network flexibility and user mobility are improved, but the ability to accurately identify the physical location of an originating call deteriorates

Engineering Contradiction:
Improvenetwork flexibilityVSAvoidlocation identification accuracy
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent introduces a location database as an intermediary component that maintains the mapping between telephone numbers and physical locations. When an emergency call is made, the system queries this database using the caller's telephone number to retrieve their current physical location, thus resolving the contradiction between network flexibility and location accuracy by decoupling the routing mechanism from direct location association.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If call back information is shared between telecommunication service providers, then emergency service response effectiveness is improved, but customer information privacy and competitive concerns deteriorate

Engineering Contradiction:
Improveemergency service responseVSAvoidinformation privacy risk
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the location information from the call back number itself and stores it separately in a location database. The emergency service system only receives the call back number for identification purposes, while location details are retrieved independently from the database, thus enabling emergency response effectiveness without exposing sensitive customer information to unnecessary parties.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The location database serves as a trusted intermediary that enables information sharing for emergency services while maintaining privacy controls. The database releases location information only when triggered by an emergency call event, acting as a mediator between the need for information sharing and the need to protect customer privacy.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If a key system is used to retrieve call back number and location from ALI database, then information security and privacy protection are improved, but system complexity increases

Engineering Contradiction:
Improveinformation securityVSAvoidsystem architecture complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent implements preliminary action by pre-establishing the location database with all necessary location mappings before emergency calls occur. The database is pre-configured with the ability to retrieve information using call back numbers, so that during an actual emergency, the system can quickly access information without complex real-time processing or multiple security verification layers.

Inventive Principle:
Principle #10Preliminary action
