Solution Overview

Problem

Service providers face challenges in integrating their VOIP calls with existing VOIP infrastructure due to incompatible routing data and varying routing preferences, making it difficult for new providers to join and manage their calls effectively.

Innovation Solution

A centralized computing platform, such as the BGCF, standardizes VOIP call requests by identifying the service provider and determining routing preferences using a service provider determination table and routing preference database, allowing for seamless integration and management of VOIP calls across different service providers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a centralized routing server is implemented to standardize VOIP call routing, then routing efficiency and service provider integration are improved, but system complexity and the need for centralized control infrastructure increase

Engineering Contradiction:
Improverouting efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements a centralized routing server that acts as an intermediary between service providers and the VOIP infrastructure. This server receives routing data from multiple service providers, standardizes it according to common protocols, and distributes it to appropriate routing entities. The intermediary approach resolves the contradiction by centralizing the complexity management function, allowing individual service providers to maintain simple routing configurations while achieving efficient standardized routing across the entire system.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If new service providers join the VOIP infrastructure with their own routing preferences, then service provider diversity and routing flexibility are improved, but compatibility and integration difficulty increase

Engineering Contradiction:
Improveservice provider diversityVSAvoidintegration difficulty
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal routing data format and standardized interface that allows service providers with diverse routing preferences to integrate into the VOIP infrastructure without increasing integration difficulty. The system defines common data structures and protocols that can accommodate different routing preferences while maintaining compatibility. This universality approach enables new service providers to join easily by adhering to standard interfaces, regardless of their specific routing requirements.

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

3Loss of energy

If service providers use pre-existing VOIP infrastructure instead of building their own, then infrastructure cost and resource consumption are reduced, but routing data compatibility and control flexibility are compromised

Engineering Contradiction:
Improveinfrastructure costVSAvoidrouting control flexibility
Core Design Contradiction:
Loss of energyVSAdaptability or versatility

Solution Approach 1:

The patent implements a dynamic routing data update mechanism that allows service providers to modify their routing preferences in real-time without requiring infrastructure changes. The system accepts routing data updates from service providers and dynamically adjusts routing behavior accordingly. This dynamic approach gives service providers control flexibility comparable to having their own infrastructure, while still benefiting from cost reductions through shared VOIP infrastructure.

Inventive Principle:
Principle #15Dynamics

AI summary

Methods and systems for routing voice over internet protocol (VOIP) are described. A service provider may provide a VOIP infrastructure for routing VOIP calls. One or more other service providers may join the VOIP infrastructure. A computing device may identify the service provider servicing the VOIP calls and may further process the calls accordingly.
