Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing road-vehicle communication systems fail to account for communication failures between a road and a vehicle, leading to potential communication disruptions when alternative systems are not available, resulting in disabled communication situations.
Innovation Solution
A base station equipped with prediction and control means to anticipate and mitigate communication blockages by transmitting data before a predicted communication disruption, using a variable directivity antenna to adjust communication paths and allocate resources effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If communication systems rely on ground communication only, then device complexity is reduced, but reliability deteriorates when communication blockage occurs
Solution Approach 1:
The base station predicts future communication blockage periods and transmits data before the blockage occurs. The prediction unit analyzes mobile station position and communication path conditions to forecast when blockage will happen, allowing the control unit to schedule data transmission in advance during available communication windows.
Solution Approach 2:
The system prepares communication data in advance during periods when communication is available, creating a buffer of transmitted data that ensures continuous communication even when blockage occurs. This beforehand preparation cushions against the reliability deterioration that would otherwise result from relying on ground communication only.
2Reliability
If alternative communication systems are implemented, then reliability improves, but device complexity increases
Solution Approach 1:
Instead of implementing complex alternative communication systems, the patent uses preliminary action by predicting blockage periods and transmitting data in advance during available communication windows. This single-base-station approach achieves high reliability without requiring multiple communication systems.
Solution Approach 2:
The invention extracts the prediction and control functions from complex alternative communication systems, implementing them as independent processing units within the base station. The prediction unit and control unit operate independently to manage communication data transmission, simplifying the overall system architecture while maintaining reliability.
3Loss of time
If data transmission is delayed until communication is available, then loss of time is reduced, but loss of information increases during blockage periods
Solution Approach 1:
The control unit transmits communication data before the predicted blockage period begins, using available transmission opportunities to send data in advance. This preliminary transmission ensures that no information is lost during subsequent blockage periods, as all necessary data has already been transmitted.
Solution Approach 2:
The base station continuously monitors communication path conditions and mobile station position, using this feedback to update predictions of blockage periods. The control unit adjusts transmission scheduling based on real-time feedback, ensuring optimal data transmission timing to prevent both time loss and information loss.

AI summary
A base station includes: a communication circuit configured to communicate with a mobile station; a prediction circuit configured to predict a period during which communication with the mobile station is blocked; and a controller configured to control the communication circuit in such a way that communication data to be transmitted to the mobile station in the period during which communication is blocked are transmitted in a period before the period during which communication is blocked.
