VoWiFi Entitlement Bypass for E911 Address Check Delays

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing VoWiFi systems require excessive user interaction for enabling service when a valid E911 address is not stored, hindering the dispatch of emergency services and communication through push notifications.

Innovation Solution

Implement an enhanced entitlement system that applies filters to mobile device information to temporarily or permanently bypass the E911 address check, allowing VoWiFi connection and sending a push notification to initiate the address check when necessary.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the system requires a valid E911 address to be stored before enabling VoWiFi service, then emergency services can be accurately dispatched, but excessive user interaction is required and service enabling is delayed

Engineering Contradiction:

Improveemergency services dispatch accuracyVSAvoiduser interaction requirement

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system performs preliminary actions by obtaining location information from alternative sources (GPS, cell tower triangulation, IP address geolocation) before VoWiFi service is enabled, so that E911 address information is already available when emergency services need it, eliminating the need for users to manually provide address information during service setup

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system introduces intermediary mechanisms (location determination systems, geolocation databases, push notification services) that mediate between the requirement for accurate E911 addressing and the user experience, automatically obtaining and storing location data without requiring direct user input while still ensuring accurate emergency service dispatch

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If the system checks E911 address status before allowing VoWiFi connection, then accurate location data is ensured for emergency services, but service enabling is delayed and user experience is degraded

Engineering Contradiction:

Improvelocation data accuracyVSAvoidservice enabling time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The system obtains location information from alternative sources (GPS, cell tower triangulation, IP address geolocation) before VoWiFi service is enabled, so that E911 address information is already available when needed, eliminating delays during service setup while maintaining location accuracy

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system dynamically adjusts the E911 address validation process based on available location data, using alternative location determination methods when traditional E911 address information is unavailable, allowing service enabling to proceed without unnecessary delays while maintaining location accuracy requirements

Inventive Principle:

Principle #15Dynamics

3Reliability

If the system requires manual E911 address input from users, then accurate emergency services dispatch is ensured, but excessive subscriber interaction is cumbersome

Engineering Contradiction:

Improveemergency services dispatch accuracyVSAvoidautomatic service enabling

Core Design Contradiction:

ReliabilityVSExtent of automation

Solution Approach 1:

The system implements self-service by automatically obtaining location information from multiple sources (GPS coordinates, cell tower triangulation data, IP address geolocation services) and populating E911 address fields without requiring user intervention, while still ensuring accurate emergency services dispatch through verified location data

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system uses feedback mechanisms where location data from alternative sources is continuously monitored and validated, and push notifications are sent to users to prompt them to verify or update their E911 address information, ensuring accurate emergency services dispatch while minimizing the need for manual input during service setup

Inventive Principle:

Principle #23Feedback

AI summary

Systems, methods and non-transitory computer-readable mediums are provided for an entitlement system and method having an E911 address check bypass function. Methods provided herein include receiving a request from a mobile device for enabling voice over WiFi (VoWiFi) service and checking E911 address status. Methods further include applying a filter to the request to determine that the E911 address check can be bypassed and transmitting a response to the mobile device indicating that E911 address status is not required and that VoWiFi connection is permitted, thereby bypassing the E911 address check.
