Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions for roaming tests in mobile communication, such as remote probes and network-based monitoring, face challenges like limited coverage, high costs, inability to detect frauds like SIM box, and inefficiencies in revenue assurance and quality management, especially in large countries like China and India.
Innovation Solution
A system and method that involves creating a fake profile for a roaming subscriber at a Mobile Switching Center (MSC)/Visiting Location Register (VLR) to simulate transactions and test network elements, allowing for proactive detection of roaming partner services and frauds, as well as quality assurance across both host and roaming partner networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If remote probes are deployed to test roaming services, then coverage is improved, but cost increases significantly
Solution Approach 1:
The patent creates a fake profile that copies the characteristics of a real roaming subscriber at the VLR, allowing tests to be performed without deploying physical remote probes. This virtual copy enables comprehensive roaming service testing while eliminating the need for expensive remote probe infrastructure.
Solution Approach 2:
The fake profile acts as an intermediary between the testing system and the roaming network elements. It enables indirect testing of roaming services by simulating subscriber behavior and interactions with network elements like HLR, VLR, and MSC, thereby avoiding direct deployment of remote probes in covered areas.
2Reliability
If remote probes are used for roaming tests, then some frauds can be detected, but many frauds like SIM box remain undetected
Solution Approach 1:
The system implements comprehensive monitoring and feedback mechanisms that track signaling messages and transactions between network elements. By analyzing the complete signaling flow and subscriber profile interactions, the system can detect fraudulent patterns such as SIM box operations that remote probes cannot identify.
Solution Approach 2:
The patent replaces the mechanical remote probe approach with a network-side signaling analysis system. Instead of using physical probes to test services, the system monitors and analyzes signaling messages (MAP, ISUP, SIP) and profile transactions to detect frauds, providing more comprehensive detection capability.
3Productivity
If constant roaming quality maintenance is implemented, then roaming revenue increases, but testing complexity increases
Solution Approach 1:
The fake profile system serves multiple functions simultaneously: it tests roaming service availability, validates network element responses, monitors signaling messages, detects frauds, and ensures revenue assurance. This multi-functional approach consolidates multiple testing activities into a single unified mechanism, reducing overall testing complexity.
Solution Approach 2:
The system performs preliminary testing and validation by creating and activating fake profiles before actual roaming transactions occur. This allows proactive identification of service issues and network configuration problems, enabling preventive maintenance that simplifies ongoing quality assurance.
4Difficulty of detecting and measuring
If network side signaling and monitoring are implemented, then diagnostic capability improves, but system complexity increases
Solution Approach 1:
The patent combines signaling interception, profile creation, transaction simulation, and fraud detection capabilities into an integrated system. By merging these functions into a unified architecture that operates at the network side, the system achieves comprehensive diagnostic capability while managing complexity through consolidation rather than separate distributed components.

AI summary
The present Invention provides a method for facilitating roaming tests for a host network. The method includes creating a fake profile via a gateway associated with the host network for a roaming subscriber at a Mobile Switching Center (MSC) / Visiting Location Register (VLR). The MSC/VLR is associated with at least one of the host network and a roaming partner network of the host network. The roaming subscriber is associated with both the host network and the roaming partner network. The method further includes simulating via the gateway, transactions with a first network element associated with at least one of the host network and the roaming partner network to test at least one of the first network element's response for the simulated transactions, and network routing on the roaming subscriber to a second network element associated with at least one of the host network and the roaming partner network.
