Solution Overview

Problem

Current technologies for managing roaming traffic in mobile communication networks lack real-time business intelligence, failing to provide a comprehensive understanding of inbound and outbound roaming environments, which affects revenue and service quality, and are limited in their ability to capture signaling system intelligence and mobility-related issues.

Innovation Solution

A system and method that utilizes a gateway to analyze signaling messages from roamers to determine the roaming arrangement between host and non-host networks, providing business and technical indicators for complete roaming market distribution, including market share estimation and fraud detection, without the need for remote probes or data sharing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If offline Data Clearing House (DCH) approach is used for roaming traffic management, then financial data between network operators can be managed, but real-time business intelligence is not available due to TAP file exchange delays of more than thirty days

Engineering Contradiction:
Improvebusiness intelligence availabilityVSAvoiddata delivery time
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The patent implements a proactive monitoring system that collects and analyzes roaming traffic data in real-time before billing cycles complete. The gateway captures signaling messages and usage data continuously, enabling operators to make business decisions based on current traffic patterns rather than waiting for monthly TAP file settlements.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary gateway system that sits between the roaming partners and the billing system. This gateway pre-processes signaling messages and usage data, transforming raw network data into business intelligence metrics before they reach the billing platform, thereby decoupling real-time analytics from the delayed TAP file exchange process.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of time

If Near Real Time Roaming Data Exchange (NRTRDE) approach is used, then inbound and outbound roaming usage traffic delivery is improved to less than four hours, but SS7 signaling intelligence of roaming environment is still not captured

Engineering Contradiction:
Improvedata delivery timeVSAvoidSS7 signaling intelligence
Core Design Contradiction:
Loss of timeVSLoss of information

Solution Approach 1:

The patent designs a gateway with multi-functional capabilities that simultaneously performs multiple tasks: capturing SS7 signaling messages, analyzing usage data, generating business intelligence metrics, and interfacing with billing systems. This universal gateway consolidates previously separate functions into a single platform that delivers both real-time data exchange and comprehensive signaling intelligence.

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

Solution Approach 2:

The patent segments the roaming data processing into distinct functional modules within the gateway: a signaling message capture module that intercepts SS7 messages, an analysis module that processes usage data, and a reporting module that generates business intelligence. This segmentation allows each module to specialize in capturing specific types of information while working together to provide complete roaming environment visibility.

Inventive Principle:
Principle #1Segmentation

3Reliability

If passive probe approaches are deployed at roaming links to capture SS7 signaling messages, then real time operational information is obtained, but business intelligence of roaming environment is not provided

Engineering Contradiction:
Improvereal-time monitoring capabilityVSAvoidbusiness intelligence
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The patent merges operational monitoring functions with business intelligence generation functions within a single gateway system. While passive probe approaches capture SS7 signaling messages for operational reliability, this invention combines that capability with active analysis of usage patterns, revenue impact assessment, and business metric generation, transforming operational data into actionable business intelligence.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The gateway acts as an intermediary that receives raw SS7 signaling messages from the network and transforms them into business intelligence metrics. It mediates between the operational layer (signaling messages) and the business layer (revenue, market share, fraud detection), adding analytical value that neither passive probing nor traditional billing systems provide alone.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Reliability

If remote mobile stations on test roamers are used for fraud detection, then service level issues can be detected, but the approach has limitations in footprint, user profile availability, and cannot provide information on real roaming traffic

Engineering Contradiction:
Improvefraud detection capabilityVSAvoidfootprint and user profile coverage
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements a self-service monitoring system that uses actual roaming traffic data captured at the gateway to detect fraud and anomalies. Instead of relying on external test roamers that require manual provisioning and have limited profiles, the system automatically analyzes real user traffic patterns, leveraging the natural diversity of user profiles and roaming behaviors already present in the network to identify fraudulent activities.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent inverts the traditional fraud detection approach by moving from active testing (using test roamers to probe the network) to passive monitoring (using the network's own traffic to detect anomalies). This inversion eliminates the limitations of test roamer approaches while maintaining fraud detection effectiveness by analyzing the actual roaming traffic that passes through the gateway.

Inventive Principle:
Principle #13The other way round (Inversion)

AI summary

The present invention provides a method for facilitating roaming management of a host network. The method includes obtaining at a gateway associated with the host network, signaling messages of one or more roamers. The roamers are subscribers of either the host network or one or more non-host networks. The method further includes determining by the gateway, the host network's roaming arrangement with the non-host networks, based on analysis of one or more signaling messages from the obtained signaling messages.
