Payment Support System for Interrupted Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In payment systems where users utilize mobile terminals to order and pay for services or products, there is a challenge in preventing illegal acts such as non-payment by intentionally interrupting communication, making it difficult for facilities to determine if the use price has been paid, especially when users power off their devices upon exiting.
Innovation Solution
A payment support system that includes a communication state determination processing unit to detect interrupted communication and a notification processing unit to alert both the user terminal and facility terminal, ensuring payment processing is executed even if communication is interrupted, thereby preventing illegal non-payment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system relies on continuous communication to verify payment status, then payment reliability is improved, but communication traffic and system complexity increase
Solution Approach 1:
The system performs payment execution in advance when communication interruption is detected, rather than waiting for confirmation. The payment support server proactively determines communication interruption and executes payment before the user can potentially avoid it by maintaining device power off, thus ensuring payment reliability without requiring continuous communication verification
Solution Approach 2:
The system implements a feedback mechanism where the payment support server monitors communication status between user terminals and the system. When communication interruption is detected, the server sends notifications to both the user terminal and facility terminal, creating a closed-loop feedback system that ensures payment execution while reducing unnecessary continuous communication traffic
2Reliability
If the system continuously monitors communication status to prevent non-payment, then payment security is improved, but communication traffic and processing overhead increase
Solution Approach 1:
Instead of continuous monitoring, the system uses periodic communication status checks. The payment support server determines communication interruption at specific intervals or triggered by specific events (such as when payment should have been completed), reducing communication traffic while maintaining adequate payment security monitoring
Solution Approach 2:
The system enables self-service payment execution by automatically detecting communication interruptions and triggering payment processes without requiring continuous active monitoring. The notification mechanism allows the system to inform relevant parties of the payment execution based on detected communication status changes, reducing overall communication overhead

AI summary
A payment support system includes a communication state determination processing unit, a payment processing unit, and a notification processing unit. The communication state determination processing unit determines a communication state of a user terminal of a user who uses a facility. The payment processing unit executes a process concerning payment of a use price of the facility when the communication state determination processing unit determines that communication of the user terminal has been interrupted. The notification processing unit causes at least one of the user terminal and a facility terminal installed in the facility to notify predetermined information when the communication state determination processing unit determines that communication of the user terminal has been interrupted.
