Solution Overview

Problem

Existing phone fraud prevention methods face challenges in processing capacity and determining spam calls, leading to increased load and potential damage from phone fraud.

Innovation Solution

A management server system that detects outgoing calls, measures call duration, and sends notifications to a third terminal when the call exceeds a predetermined duration, thereby reducing processing load and preventing fraud.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If voice recognition function is used to recognize and analyze voices during phone calls, then phone fraud detection capability is improved, but processing load and system complexity increase significantly

Engineering Contradiction:

Improvephone fraud detection capabilityVSAvoidprocessing capacity requirement

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the core detection function from complex voice recognition and implements a simplified call duration monitoring mechanism. Instead of analyzing voice content, the system only monitors call duration parameters, which significantly reduces processing requirements while maintaining fraud detection capability through the notification mechanism to third terminals.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the mechanical voice recognition system with a simpler parameter monitoring system. By substituting complex acoustic analysis with basic duration measurement and threshold comparison, the system achieves fraud detection with minimal processing load.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If special means for determining spam phone calls are provided, then spam call identification is improved, but device complexity and processing load increase

Engineering Contradiction:

Improvespam call identification accuracyVSAvoidspecial determination means

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses a simple, lightweight notification mechanism instead of complex determination systems. By implementing a basic duration threshold check and sending notifications to third terminals, the system achieves spam call identification without requiring expensive or complex determination means.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Reliability

If call monitoring is performed to detect potential fraud, then fraud prevention capability is improved, but processing load increases

Engineering Contradiction:

Improvefraud prevention capabilityVSAvoidprocessing load

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent implements partial monitoring by only tracking call duration parameters rather than analyzing all call characteristics. This selective monitoring approach maintains fraud prevention capability while minimizing processing load by focusing solely on the duration threshold condition.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

Included are an outgoing call detection unit configured to detect an outgoing call from a first communication terminal to a second communication terminal, a connection control unit configured to cause the outgoing call detected by the outgoing call detection unit to arrive at the second communication terminal, a call duration measurement unit configured to measure a time from when a phone call is started, which is a duration of the phone call, between the first communication terminal and the second communication terminal, and a notification unit configured to transmit, when the duration measured by the call duration measurement unit exceeds a predetermined duration before the phone call ends, a predetermined notification to a third communication terminal.
