Solution Overview

Problem

Integrating on-premises session border controllers (SBCs) with dedicated voice circuits into the evolving landscape of cloud-based private branch exchanges (PBXs) and conversational AI platforms is challenging due to design differences and the dynamic nature of cloud-based solutions, necessitating a solution that maintains existing investments while leveraging cloud agility.

Innovation Solution

Cloud-based voice interconnects are established through direct partner interconnects and Internet-based connectivity, eliminating the need for separate circuits and infrastructure, allowing flexible and cost-effective setup and teardown of voice interconnect systems, integrating with cloud-based IP multimedia subsystems and edge SBCs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If on-premises SBCs with dedicated voice circuits are integrated into cloud-based PBX systems, then existing infrastructure investments are maintained, but integration complexity and deployment time increase

Engineering Contradiction:
Improveexisting infrastructure investment maintenanceVSAvoidintegration complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a cloud-based SBC as an intermediary component that mediates between the on-premises SBC/dedicated circuits and the cloud-based PBX system. This cloud-based SBC acts as a bridge, translating and adapting protocols and interfaces, thereby reducing integration complexity while preserving existing infrastructure investments.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates a virtualized copy of the SBC functionality in the cloud environment. Instead of directly integrating physical on-premises SBCs, the system replicates SBC capabilities as software instances in the cloud, simplifying integration while maintaining the functional equivalence of existing hardware investments.

Inventive Principle:
Principle #26Copying

2Stability of the object's composition

If dedicated voice circuits are used for SBC connectivity, then connection stability is improved, but deployment time and costs increase

Engineering Contradiction:
Improveconnection stabilityVSAvoiddeployment time
Core Design Contradiction:
Stability of the object's compositionVSLoss of time

Solution Approach 1:

The patent replaces the mechanical/physical dedicated voice circuit infrastructure with Internet-based IP connectivity. This substitution maintains connection stability through protocol optimization and quality of service mechanisms while eliminating the time-consuming physical circuit installation and configuration processes.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If cloud-based SBCs are implemented without dedicated circuits, then deployment flexibility and speed improve, but network investment requirements increase

Engineering Contradiction:
Improvedeployment speedVSAvoidnetwork investment
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

The patent creates a universal cloud-based SBC platform that can serve multiple customers and functions through virtualization. This multi-functional approach allows rapid deployment for different scenarios using shared network infrastructure, reducing the need for additional dedicated network investments while maintaining deployment flexibility and speed.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

An example cloud-based voice interconnect system includes data processing hardware of a cloud-based computing platform, a network, and a public telecom carrier system. The data processing hardware is in communication with memory hardware storing instructions that, when executed on the data processing hardware, cause the data processing hardware to perform operations including providing a private virtualized computing environment, and implementing a private cloud-based session border controller (SBC) in the virtualized computing environment. The public telecom carrier system is connected to the private cloud-based SBC via the network, and is configured to provide telecom services between the private cloud-based SBC and customers of the public telecom carrier system.
