Server Apparatus for Selecting Target Vehicles in V2X Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing V2X communication systems face challenges in identifying and communicating with specific vehicles for large-volume data exchange, such as video information, especially in scenarios where PC5 communication is insufficient.
Innovation Solution
A server apparatus that receives communication request messages from vehicles, selects target vehicles based on designated selection conditions, and transmits communication requests to these vehicles, enabling the exchange of communication connection information for subsequent large-volume data communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If PC5 communication is used for vehicle-to-vehicle data exchange, then direct communication between vehicles is enabled, but large-volume data communication capability is insufficient
Solution Approach 1:
The patent introduces a server apparatus as an intermediary between vehicles. The server receives communication requests from first vehicles, selects appropriate second vehicles based on communication connection information, and facilitates Uu communication through the network. This mediator approach enables large-volume data communication while maintaining vehicle identification capability.
2Quantity of substance
If Uu communication is used for large-volume data exchange, then data communication capability is improved, but vehicle identification becomes difficult without connection destination information
Solution Approach 1:
The server apparatus performs preliminary actions by storing communication connection information of multiple second vehicles in advance and maintaining a mapping relationship between positional information and communication connection information. When a communication request arrives, the server can immediately retrieve and provide the appropriate connection information without requiring the requesting vehicle to know the destination vehicle's details beforehand.
Solution Approach 2:
The server acts as an intermediary that holds and manages communication connection information. It receives requests from first vehicles, uses positional information to identify the intended second vehicle, retrieves the corresponding communication connection information from storage, and provides it to the first vehicle. This enables Uu communication while preserving vehicle identification capability.
3Ease of operation
If existing V2X communication methods are used, then basic vehicle communication is enabled, but communication with specific vehicles under intended conditions cannot be reliably identified
Solution Approach 1:
The server apparatus provides feedback by returning communication connection information to the first vehicle after successful vehicle selection. This feedback mechanism enables the first vehicle to establish targeted communication with the identified second vehicle, improving both ease of operation and selection accuracy simultaneously.

AI summary
In order to make it possible to carry out communication while identifying a vehicle of an intended condition, a server apparatus (1) includes: a reception means (11) for receiving, from a first vehicle (31), a communication request message using wireless communication, the communication request message designating a selection condition for selecting another vehicle; a selection means (12) for selecting a second vehicle (33, 34) that satisfies the selection condition; and a transmission means (13) for transmitting the communication request message to the second vehicle (33, 34).
