Vehicle Wireless Channel Prediction Using On-Route Access Points
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies face low prediction accuracy of frequency channels with less interference due to the acquisition of communication status information at a distance from the target point, leading to significant divergence by the time the vehicle reaches the target point.
Innovation Solution
A wireless communication control device and method that acquires identification information for on-route access points, communicates with them to gather real-time communication status information, and predicts frequency channels with less interference as the vehicle approaches, using inter-vehicle and cellular communication to minimize time lag and information divergence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If communication status information is acquired at a distance from the target point, then the acquisition can be performed in advance, but the prediction accuracy of frequency channels with less interference decreases due to significant divergence by the time the vehicle reaches the target point
Solution Approach 1:
The system performs preliminary actions by acquiring communication status information from on-route access points before the vehicle reaches the target communication range. The controller acquires identification information of access points along the route and obtains communication status information in advance, then predicts the frequency channel with less interference based on this preliminary data, resolving the contradiction between early acquisition and prediction accuracy.
2Reliability
If communication status information is acquired via inter-vehicle communication, then real-time information can be obtained, but the system complexity increases due to coordination requirements
Solution Approach 1:
The patent uses on-route access points as intermediaries to obtain communication status information. Instead of directly coordinating between multiple vehicles, the system leverages existing access points along the route as mediators that provide communication status data, thereby reducing system complexity while maintaining real-time information reliability.
3Measurement precision
If the vehicle acquires communication status information close to the target point, then prediction accuracy improves, but the time available for prediction and channel selection is reduced
Solution Approach 1:
The controller acquires communication status information from on-route access points in advance before reaching the target point. This preliminary acquisition allows the system to predict the frequency channel with less interference and complete channel selection before the vehicle enters the target communication range, resolving the contradiction between prediction accuracy and time availability.

AI summary
By a wireless communication control device that controls a wireless communication device or a wireless communication control method, identification information for identifying the access point of a target network existing on a route of a vehicle is acquired, an on-route access point of the target network on the route is identified, communication status information regarding a communication status in a target communication range to which the vehicle comes close is acquired, and a frequency channel with less interference in wireless communication in the target communication range is predicted.
