Solution Overview

Problem

In V2X communication, vehicles may incur communication costs for relaying data for other vehicles, and there is a need to determine whether the data being relayed is related to the vehicle itself or another vehicle.

Innovation Solution

A communication device sets unique quality of service (QoS) identification information for relayed data, allowing the network to differentiate between self-data and relayed data, thereby enabling accurate cost charging.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a vehicle relays communication for another vehicle using a paid communication service, then the relayed data can be transmitted to the network, but the relaying vehicle bears communication costs for data not related to itself

Engineering Contradiction:
Improverelay communication capabilityVSAvoidcommunication cost
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The patent introduces QoS identification information as an intermediary marker that distinguishes relayed data from self-generated data. This mediator enables the network to identify and separately charge relay communication costs, preventing vehicles from bearing costs for data not related to themselves while maintaining relay functionality.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the parameter of data identification by adding QoS identification information to relayed data packets. This parameter change enables the network to differentiate between self-data and relayed data, allowing accurate cost allocation and preventing unnecessary communication costs for vehicles.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If a vehicle relays communication without data identification, then relay transmission can occur, but it becomes difficult to determine whether the data is related to the vehicle itself or another vehicle

Engineering Contradiction:
Improverelay transmission functionVSAvoiddata origin identification
Core Design Contradiction:
Ease of operationVSDifficulty of detecting and measuring

Solution Approach 1:

The patent applies the concept of marking data with distinctive identifiers (QoS identification information) similar to color-coding, which allows easy visual or systematic differentiation between relayed data and self-generated data without changing the fundamental relay transmission function.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent segments data identification by introducing separate QoS identification information that specifically marks relayed data. This segmentation enables clear distinction between different data types, making it easy to determine data origin while preserving the relay transmission capability.

Inventive Principle:
Principle #1Segmentation

AI summary

A communication device that relays communication between a first another device and a second another device sets first identification information regarding a quality of a service in communication of user data of the second another device to a value that is not used as identification information of a quality of a service in communication of user data between the first another device and the communication device, and relays the communication between the first another device and the second another device, based on the first identification information.
