Solution Overview

Problem

Existing telecommunications systems require complex and costly third-party intermediaries for interconnecting users across different service provider networks, leading to inefficient and expensive communication routing, especially in mobile roaming scenarios.

Innovation Solution

Implementing a peer-to-peer interconnect system that allows the home network of a roaming endpoint to directly route control signaling and media, eliminating the need for centralized intermediaries and optimizing communication paths between service providers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If third-party intermediaries are used to connect users across different service provider networks, then compatibility and connection capability are improved, but system complexity and cost increase

Engineering Contradiction:
Improveconnection capabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts and eliminates the third-party intermediary component from the communication path. By implementing direct peer-to-peer routing between service provider networks, the system removes the intermediate routing entity that previously added complexity, while maintaining connection capability through direct network interconnection

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The home network acts as a mediator that enables direct routing decisions without requiring external third-party intermediaries. The home network's routing entity determines optimal direct paths between visited networks, replacing the traditional third-party intermediary model with a decentralized home-network-controlled approach

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If communication sessions route through multiple third parties and carriers, then connection capability is maintained, but cost and routing complexity increase

Engineering Contradiction:
Improveconnection capabilityVSAvoidcost
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent implements direct routing that allows communication sessions to skip intermediate third-party carriers and route directly between source and destination networks. This eliminates unnecessary routing hops and associated connection/termination fees while maintaining reliable connectivity through direct network peering

Inventive Principle:
Principle #21Skipping (Rushing through)

3Ease of operation

If control signaling and media are routed through home networks in mobile roaming, then service control capability is improved, but routing efficiency and cost decrease

Engineering Contradiction:
Improveservice control capabilityVSAvoidrouting efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent segments the routing of control signaling and media traffic, allowing them to follow different paths. Control signaling continues to route through home networks for service control, while media traffic takes direct optimized paths through visited networks, achieving both service control capability and routing efficiency simultaneously

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The routing system dynamically determines paths based on traffic type and network conditions. The home network's routing entity can adaptively select whether control signaling and media traverse the same path or diverge, optimizing for both service control requirements and routing efficiency in different scenarios

Inventive Principle:
Principle #15Dynamics

AI summary

Embodiments of methods and systems for direct routing of communication sessions for mobile IP communication end points are presented. The methods may be implemented in a service provider network. In one embodiment, a method includes receiving, on a first service provider network, a request for access to a target communication device, the target communication device being associated with a second service provider network. The method may also include receiving an indicator, from the second service provider network, that the target communication device is roaming on a third service provider network. Additionally, the method may include establishing a peer-to-peer communication link with the target communication device on the third service provider network by a direct peer-to-peer interconnection process.
