Vehicular Message Distribution Entity Selective Targeting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current C-V2X communication systems face inefficiencies and unreliability in transmitting vehicular messages to target vehicles, leading to resource wastage and suboptimal delivery of relevant information, as they often transmit messages to vehicles that do not require them, thereby consuming resources without providing value.
Innovation Solution
The implementation of a vehicular message distribution entity that uses unicast transmission with selective targeting of vehicles based on geographical proximity, driving context, and auxiliary information, such as sensor data and message history, to ensure that messages are delivered only to vehicles that are relevantly affected by the source vehicle's information, thereby optimizing resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicular messages are transmitted to all vehicles in the network, then message delivery coverage is maximized, but resource consumption increases and delivery reliability decreases
Solution Approach 1:
The patent applies local quality by differentiating message delivery based on individual vehicle characteristics and contexts. Instead of uniform broadcasting to all vehicles, the system selectively delivers messages to specific target vehicles based on their geographical location, driving behavior, and relevance to the message content, thereby optimizing resource usage while maintaining delivery reliability for affected vehicles
Solution Approach 2:
The patent implements partial action by transmitting messages only to the necessary subset of vehicles rather than all vehicles in the network. The message distribution entity determines which vehicles are actually affected by the source vehicle's information and delivers messages only to those vehicles, avoiding unnecessary transmissions to vehicles that do not require the information
2Loss of information
If vehicular messages are transmitted to all vehicles in the network, then information dissemination is maximized, but resource wastage increases
Solution Approach 1:
The system applies local quality by tailoring message delivery to specific vehicle contexts and requirements. The message distribution entity evaluates individual vehicle characteristics and delivers information selectively to vehicles that need it, ensuring effective information dissemination to affected vehicles while avoiding wasteful transmissions to vehicles that do not require the information
Solution Approach 2:
The patent implements self-service through the message distribution entity that autonomously determines which vehicles should receive messages based on evaluated criteria such as geographical proximity, driving context, and message relevance. This intelligent selection mechanism ensures information is disseminated efficiently without manual intervention or unnecessary broad broadcasting
3Productivity
If messages are transmitted to vehicles that do not require them, then coverage is maximized, but delivery efficiency decreases
Solution Approach 1:
The patent applies local quality by customizing message delivery based on specific vehicle characteristics and contexts. The message distribution entity evaluates each potential target vehicle's relevance to the message content and delivers messages only to vehicles that require them, thereby maximizing delivery efficiency while minimizing unnecessary message transmissions
Solution Approach 2:
The patent implements partial action by transmitting messages only to the necessary subset of vehicles rather than all vehicles in the network. This selective delivery approach maximizes productivity by ensuring messages reach affected vehicles efficiently while reducing the total quantity of transmissions by excluding vehicles that do not require the information

AI summary
According to an aspect, a method for selecting target vehicles for transmission by a vehicular message distribution entity is provided. Initially, map information and driving context information of a plurality of vehicles is maintained in a database of the vehicular message distribution entity in a communications system. Upon receiving from a first source vehicle a vehicular message comprising at least driving context information, the vehicular message distribution entity selects one or more vehicles in proximity of the first source vehicle from the plurality of vehicles based on geographical locations of said vehicles. Then, the vehicular message distribution entity further selects a first set of one or more target vehicles from the one or more vehicles based on driving context information and the map information. Finally, the vehicular message distribution entity causes sending the vehicular message to the first set using unicast transmission.
