Test Call Generation (TCG) in Fraud Management: A Detailed Overview
Introduction
In the telecommunications sector, Test Call Generation (TCG) is a proactive mechanism for detecting, preventing, and managing fraud. With telecom operators facing various types of fraud—ranging from SIM box fraud to CLI fraud—TCG provides a way to regularly monitor and assess network integrity through automated, controlled test calls or messages. This blog post explores the role of TCG in fraud management, its functionality, and why it’s indispensable for telecom operators.
What is Test Call Generation (TCG)?
TCG is a method telecom operators use to generate and route test calls across their networks. These test calls simulate regular user activities, such as making phone calls or sending messages, to monitor performance, identify vulnerabilities, detect anomalies, and ensure system integrity. Unlike actual user calls, TCG-generated calls follow specific patterns and scenarios, allowing operators to assess multiple aspects of the network efficiently.
TCG plays a crucial role in detecting Subscription Fraud, Wangiri Fraud, IRSF (International Revenue Share Fraud), and other types of telecom fraud. Specifically, this testing technology is widely used to:
- Detect fraud and bypass activities such as SIM box fraud.
- Evaluate quality of service (QoS) for voice, SMS, and data.
- Ensure regulatory compliance for interconnect billing and other legal frameworks.
Why is TCG Important in Fraud Management?
Telecom fraud is a multi-billion-dollar problem impacting operators worldwide. Fraudsters continuously evolve their tactics, making it essential for operators to stay ahead. Here’s why TCG is a vital component of fraud management:
1. Fraud Detection
TCG is instrumental in identifying SIM box fraud, where fraudsters bypass international call rates using local SIM cards to route international calls. By generating test calls from specific locations, operators can identify suspicious activities before they escalate into major revenue losses.
2. Network Performance Monitoring
Beyond fraud detection, TCG serves as a robust tool for monitoring network performance. Operators can track call quality metrics, latency, and other performance indicators to ensure optimal network functionality.
3. Billing Verification
TCG helps verify the accuracy of call detail records (CDRs) by comparing generated test calls with billing system records. This ensures that users and interconnection partners are billed correctly.
4. International Call Verification
Test calls are often sent internationally to confirm correct call termination and detect fraud techniques like “grey routes,” which illegitimately terminate calls, leading to revenue loss.
5. Cost Savings
By detecting and preventing fraud early, TCG helps operators avoid substantial financial losses associated with fraudulent activities.
6. Regulatory Compliance
In many countries, telecom operators must meet specific service quality and billing accuracy standards. TCG ensures compliance, reducing the risk of penalties from regulators.
Types of Telecom Fraud Detected Using TCG
SIM Box Fraud
Fraudsters set up multiple SIM cards in a “SIM box” to terminate international calls as local ones, avoiding higher termination fees. TCG detects irregular call patterns, indicating SIM box activity.
CLI Manipulation
Fraudsters may manipulate Caller Line Identification (CLI) to conceal the origin of a call, often leading to fraud. TCG can detect such cases by tracing test calls and comparing them with CLI data.
Subscription Fraud
Fraudsters obtain services using fake or stolen identities. TCG helps identify unusual usage patterns associated with these accounts.
Premium Rate Service (PRS) Fraud
By generating test calls to premium-rate numbers, TCG can detect fraudsters initiating premium-rate calls to generate revenue illegally.
PBX Hacking
Fraudsters hack into PBX systems to make unauthorized calls. TCG can simulate PBX call patterns to detect vulnerabilities.
Revenue Leakage
Incorrect routing or call termination can lead to revenue leakage. TCG ensures accurate routing and revenue capture by simulating various call scenarios.
How TCG Works
1. Test Script Creation
TCG platforms enable users to define parameters for test calls, such as duration, destination, time intervals, and type (voice, SMS, or data). Example scenarios include:
- Simulating international calls to high-risk destinations.
- Testing premium rate numbers.
- Generating calls during off-peak hours to detect unusual activity.
2. Test Call Generation
Once the script is created, the TCG system initiates test calls or SMS messages according to predefined rules. These calls are routed through the network like regular calls and distributed across various points and countries, depending on the scenario.
3. Data Collection
The TCG system records key data, including call quality (e.g., jitter, packet loss), call success rate, and latency. For fraud detection, the system looks for anomalies, such as unusual routing patterns or discrepancies in expected call termination points.
4. Analysis and Reporting
The TCG platform monitors results and provides detailed reports. Key metrics such as call duration, routing paths, and billing records are analyzed for discrepancies. If irregularities or fraud are detected, alerts are triggered for further investigation.
5. Automated Response
Advanced TCG systems integrate with fraud management platforms, enabling automatic preventive actions such as:
- Blocking suspected fraudsters.
- Rerouting traffic.
- Updating fraud rules.
- Enhancing security measures to prevent revenue loss.
Benefits of Using TCG in Fraud Management

Types of Mobile Money Fraud
Below are the main types of Mobile Money fraud:
Cash-Out Fraud: Dishonest agents at sales points withdraw money from a user’s account without authorization. This type of fraud is common where agents exploit their position to illegally access and transfer funds. This often without the victim realizing until it’s too late.
Phishing Fraud: Involves social engineering techniques, such as fraudsters calling or messaging the victim, claiming that they accidentally sent money to their Mobile Money account. The fraudster then requests the victim return the money, tricking them into sending their own funds.
International Transfer Fraud: Mobile Money accounts are increasingly being used to illegally transfer stolen or laundered funds across borders. Fraudsters exploit the cross-border transfer capabilities of Mobile Money to move illicit funds. Making the tracing and recovery of the money difficult.
Commission Fraud: Agents may split customer deposits into smaller transactions to artificially inflate the commission they receive from the operator. This fraudulent activity not only undermines the operator’s commission structure but can also lead to inflated transaction fees for users.
SIM Swapping Fraud: Fraudsters use social engineering to convince mobile service providers to transfer a victim’s phone number to a new SIM card, allowing them to take over the victim’s Mobile Money account. This type of fraud has become increasingly sophisticated, with criminals often targeting individuals who have high-value accounts.
As of 2023, the risks associated with Mobile Money fraud continue to escalate. In recent years, it is estimated that the financial sector has faced substantial losses, with some reports suggesting that billions of dollars are lost annually due to sophisticated scams targeting Mobile Money services. As technology evolves, fraudsters are constantly adapting, employing increasingly complex methods to exploit system vulnerabilities. Consequently, the need for enhanced security measures and robust fraud detection systems has never been more critical in safeguarding against these threats.
