Solution Overview

Problem

Devices lacking a SIM or eSIM, such as desktop computers and tablets, cannot comply with regulatory requirements for real-time location verification when using VOIP services, as they lack direct association with a cellular network.

Innovation Solution

Establish a temporary binding between a non-mobile device and a mobile device with native connectivity through a proximity network using short-range wireless technologies like Bluetooth Low Energy or Wi-Fi Direct, allowing the mobile device to provide location information to the non-mobile device, ensuring compliance with regulatory requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a non-mobile device (without SIM/eSIM) uses VOIP services, then flexibility and accessibility are improved, but compliance with regulatory location verification requirements deteriorates

Engineering Contradiction:
ImproveflexibilityVSAvoidregulatory compliance
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces a mobile device as an intermediary between the non-mobile device and the cellular network. The mobile device acts as a mediator that provides location verification capabilities to the non-mobile device through proximity-based binding, enabling regulatory compliance without requiring the non-mobile device to have direct cellular connectivity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If a non-mobile device binds to a mobile device for location verification, then regulatory compliance is improved, but device complexity increases

Engineering Contradiction:
Improveregulatory complianceVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The mobile device autonomously manages the binding relationship and location verification process. The system automatically detects proximity, establishes bindings, and maintains compliance status without requiring complex user configuration or manual intervention, thereby reducing the perceived complexity for users.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The binding between devices is established in advance before VOIP calls are made. By pre-establishing the proximity relationship and location verification capability, the system eliminates the need for complex real-time compliance checks during calls, simplifying the overall process.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If real-time location verification is implemented for VOIP calls, then regulatory compliance is improved, but loss of time in call setup increases

Engineering Contradiction:
Improveregulatory complianceVSAvoidcall setup time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

Location verification and device binding are performed in advance before the VOIP call is initiated. The proximity relationship is established and validated prior to call setup, eliminating delays during the actual call initiation process while maintaining real-time compliance.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Once binding is established, the location verification capability remains continuously valid for the duration of the bound state. This allows multiple VOIP calls to be made without repeated verification delays, as the binding relationship persists and maintains compliance status continuously.

Inventive Principle:
Principle #20Continuity of useful action

AI summary

The present invention relates to telecommunications and specifically to methods and systems for enabling Internet-based telephone calls using Over-the-Top (OTT) communication services while ensuring compliance with jurisdictional regulatory requirements. Described herein are techniques for binding a non-mobile device, such as a laptop or tablet, to a mobile device capable of providing real-time location information. The binding is established through a local proximity network using short-range wireless communication protocols. The mobile device transmits its connectivity status and location data to either the non-mobile device or a cloud-based communication service, which then acts as a gatekeeper to permit or inhibit call initiation based on the received status information. This system ensures that calls made from the non-mobile device can be accurately located in real-time, facilitating compliance with regulations that mandate location verification for emergency services and lawful intercepts.
