Solution Overview

Problem

Conventional network environments face challenges in providing high-definition voice quality during call sessions between mobile and fixed communication devices due to transcoding issues, increased power consumption, and complexity in control planes, which also affect geolocation identification and call handover capabilities.

Innovation Solution

The implementation of a high-definition voice fixed mobile convergence (HD-V FMC) network architecture that includes Voice over Long Term Evolution (VoLTE), Business Voice over Internet Protocol (BVoIP), IP Multimedia Subsystem (IMS), and Fixed Mobile Convergence (FMC) attributes, allowing for vocoder bypass and network presence mapping to reduce transcoding iterations and enhance voice quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple SIM cards are used in a single mobile device to provide multiple telephone numbers, then the functionality for multiple personas is improved, but power consumption increases, physical size increases, battery life decreases, and manufacturing cost increases

Engineering Contradiction:

Improvemultiple telephone numbers supportVSAvoidpower consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent implements a universal SIM card design that can store and manage multiple subscriber profiles (e.g., personal and business numbers) within a single physical card. This allows one SIM card to perform the function of multiple SIM cards, enabling multiple telephone numbers support without requiring multiple separate SIM cards in the device.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines multiple subscriber identities and telephone numbers into a single SIM card structure. Instead of using separate SIM cards for different personas, the system merges multiple profile data sets into one unified SIM card that can be managed and switched between electronically.

Inventive Principle:

Principle #5Merging (Combining)

2Adaptability or versatility

If multiple SIM cards are used in a single mobile device to provide multiple telephone numbers, then the functionality for multiple personas is improved, but the physical size of the phone increases

4Adaptability or versatility

If conventional static transcoding is used in call sessions between mobile and fixed devices, then network compatibility is maintained, but voice quality is degraded

Engineering Contradiction:

Improvenetwork compatibilityVSAvoidvoice quality

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent implements dynamic transcoding that adapts to the specific call scenario. Instead of using a fixed static transcoding scheme, the system dynamically selects and applies appropriate transcoding parameters based on the network type (mobile or fixed), call direction, and voice quality requirements, thereby maintaining compatibility while improving voice quality.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the transcoding parameters dynamically based on the network environment and call characteristics. By adjusting transcoding settings rather than using fixed parameters, the system can optimize voice quality for different network combinations while maintaining broad network compatibility.

Inventive Principle:

Principle #35Parameter changes

5Ease of operation

If conventional network environments are used for IP-based calls, then call setup is simplified, but geolocation identification becomes difficult and FCC 911 mandate compliance is limited

Engineering Contradiction:

Improvecall setup simplicityVSAvoidgeolocation identification

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The patent introduces an intermediary location identification mechanism that works between the IP-based call system and the FCC 911 mandate requirements. This intermediary component captures and processes location information during call setup, enabling geolocation identification without complicating the underlying IP call setup procedures.

Inventive Principle:

Principle #24Intermediary (Mediator)

6Ease of operation

If conventional network environments are used for IP-based calls, then call setup is simplified, but call handover capabilities are limited

Engineering Contradiction:

Improvecall setup simplicityVSAvoidcall handover capabilities

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic network selection and handover capabilities that allow calls to transition between different network types (mobile, fixed, WiFi). The system dynamically adjusts call routing and network selection based on availability and quality, providing seamless handover while maintaining simplified call setup through automated decision-making.

Inventive Principle:

Principle #15Dynamics

Publication Date: 2022.06.14 AT&T INTELLECTUAL PROPERTY I L P

AI summary

Concepts and technologies provided herein can provide high-definition voice for fixed mobile convergence on mobile and wireline networks. A processor executing instructions can detect a call request associated with a called telephone number to setup a call session, where the call request is initiated from a calling device associated with an originating network. The processor can determine a call path for the call session from the originating network to a receiving network. The processor can create a fixed mobile convergence request to alert an electronic number mapping system of the call path for the call session from the originating network to the receiving network. The electronic number mapping system can provide a network presence map identifying a plurality of call receiving devices associated with the called telephone number that are available to participate in the call session via the receiving network.
