Solution Overview

Problem

Conventional methods for detecting telecom fraud, such as SIM box and SIM cloning, are reactive and inefficient due to the manual analysis of vast amounts of data, making it difficult to identify perpetrators in a timely manner, leading to significant revenue loss and service quality reduction.

Innovation Solution

Implementing a real-time data analysis and risk model system that processes phone call metadata streamed to a database server, using big-data analytical tools and authentication risk models to derive phone usage patterns and detect fraudulent activity proactively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual analysis of individual calls is performed to detect fraud, then investigation accuracy is improved, but detection speed deteriorates due to the huge volume of data (∼4 TB per hour)

Engineering Contradiction:
Improvefraud detection accuracyVSAvoidfraud detection speed
Core Design Contradiction:
Measurement precisionVSSpeed

Solution Approach 1:

The patent replaces manual mechanical analysis with automated electronic data processing systems. The system uses computer-based analytics to process phone call metadata at scale, substituting human investigators with algorithmic analysis that can handle ∼4 TB of signaling data per hour automatically, thereby maintaining detection accuracy while dramatically improving speed.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent extracts only the essential metadata elements needed for fraud detection from the vast volume of phone call data. By identifying and analyzing specific key indicators (such as call patterns, frequency, duration, and routing information) rather than processing every detail of the ∼4 TB hourly data stream, the system achieves rapid fraud detection without sacrificing accuracy.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If manual analysis of individual subscriber accounts is performed, then fraud investigation thoroughness is improved, but productivity deteriorates due to the time-consuming nature of examining each call

Engineering Contradiction:
Improvefraud investigation thoroughnessVSAvoidfraud detection productivity
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent replaces the manual investigative process with automated electronic analysis systems that can examine thousands of calls simultaneously. The system maintains thoroughness by using multiple analytical algorithms to assess various fraud indicators, while productivity increases because the electronic system processes data orders of magnitude faster than human investigators working individually through subscriber accounts.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent creates a universal fraud detection system that handles multiple types of fraud simultaneously (international call fraud, domestic call fraud, SIM box fraud, etc.) through a single integrated platform. This multi-functional approach allows the system to maintain comprehensive investigation thoroughness across diverse fraud scenarios while achieving high productivity through centralized automated processing rather than separate manual investigations for each case.

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

3Measurement precision

If reactive fraud detection is used, then investigation accuracy is improved, but loss prevention capability deteriorates due to the delayed detection of fraudulent activity

Engineering Contradiction:
Improvefraud identification accuracyVSAvoidrevenue loss
Core Design Contradiction:
Measurement precisionVSLoss of energy

Solution Approach 1:

The patent implements preliminary fraud detection by analyzing phone call metadata in real-time as calls are made, rather than waiting for reactive investigation after fraud is discovered. The system continuously monitors call patterns and identifies fraudulent activity during its occurrence, enabling proactive intervention that prevents revenue loss while maintaining accurate fraud identification through real-time pattern recognition.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent incorporates feedback mechanisms where the system continuously learns from detected fraud patterns and adjusts its detection algorithms accordingly. By analyzing incoming call metadata streams and comparing them against known fraud patterns, the system provides real-time feedback that improves detection accuracy while enabling immediate response to fraudulent activity, thereby preventing revenue loss before it accumulates.

Inventive Principle:
Principle #23Feedback

AI summary

Techniques of detecting telecom fraud involve applying a combination of real-time data analysis and risk models typically used in authentication applications to phone call metadata that is streamed to a database server on a continual basis to derive phone usage patterns as the database server receives the phone usage data. The database server then compares the derived phone usage patterns to patterns of fraudulent phone usage in order to detect SIM box or SIM cloning fraud in the streamed data. A comparison result that indicates the likelihood of such fraud in a vast set of phone calls may take the form of a risk score derived using risk models typically found in authentication applications.
