Solution Overview

Problem

Current Electronic Toll Collection (ETC) systems primarily focus on vehicle-to-roadside payments, neglecting inter-vehicle payment scenarios, which require additional devices and dedicated communication systems, limiting their applicability and security.

Innovation Solution

An inter-vehicle wireless payment method utilizing a 5G communication network, where a vehicle initiates a payment request to a base station, which uses Mobile Edge Computing to encrypt and broadcast information, allowing vehicles to establish direct Device-to-Device communication for secure transactions, even in large-scale or congested scenarios.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If ETC technology is used for vehicle-to-roadside payment, then payment functionality is achieved, but inter-vehicle payment capability is lost and additional dedicated devices are required

Engineering Contradiction:

Improvepayment scenario coverageVSAvoiddedicated device requirement

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent enables smartphones to perform both vehicle-to-roadside payment and inter-vehicle payment functions by integrating 5G communication capabilities and D2D communication protocols into the existing mobile payment framework, eliminating the need for separate dedicated devices for different payment scenarios

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The base station acts as an intermediary that facilitates D2D communication between vehicles by allocating frequency bands and managing communication resources, enabling direct vehicle-to-vehicle payment without requiring complex peer-to-peer negotiation protocols

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If traditional ETC communication is used, then highway toll collection is achieved, but inter-vehicle payment scenarios are not supported

Engineering Contradiction:

Improveapplication scenario rangeVSAvoidpayment system completeness

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements dynamic communication mode switching between traditional ETC mode (vehicle-to-roadside) and D2D communication mode (vehicle-to-vehicle), allowing the system to adapt to different payment scenarios in real-time and maintain reliability across diverse application contexts

Inventive Principle:

Principle #15Dynamics

3Ease of operation

If payment information is broadcast without encryption, then communication simplicity is maintained, but security is compromised

Engineering Contradiction:

Improvecommunication simplicityVSAvoidpayment information security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent applies selective encryption where only sensitive payment information fields are encrypted using recipient-specific keys, while non-sensitive metadata remains unencrypted, achieving a balance between security requirements and communication efficiency

Inventive Principle:

Principle #3Local quality

4Speed

If D2D communication is established between vehicles, then transmission rate is improved, but frequency band allocation complexity increases

Engineering Contradiction:

Improvetransmission rateVSAvoidfrequency band management

Core Design Contradiction:

SpeedVSDevice complexity

Solution Approach 1:

The base station serves as a central coordinator that manages frequency band allocation for D2D communications, assigning specific resource blocks to vehicle pairs and handling interference management, thereby enabling high-speed direct communication without requiring complex distributed coordination protocols

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

An inter-vehicle wireless payment method employing a 5G communication network. The method comprises the followings steps: a requesting vehicle sending a payment request to a base station (S100); the base station searching for vehicle information of a friend vehicle of the requesting vehicle on the basis of the payment request (S200); the base station encrypting request information by means of the vehicle information of the friend vehicle and broadcasting the same (S300, 400); vehicles in a broadcast range of the base station decoding broadcast information by means of vehicle information of said vehicles, and upon successful decoding, the friend vehicle acting as a responding vehicle and acquiring the request information (S500); the responding vehicle generating payment information on the basis of the request information and sending the same to the base station, the base station sending the payment information to a payment platform, and the payment platform returning a payment result to the responding vehicle (S600); and the base station allocating a D2D communication channel to the requesting vehicle and the responding vehicle, and the responding vehicle and the requesting vehicle communicating via the D2D communication channel (S700). The disclosure achieves vehicle-to-vehicle communication and ensures payment security.
