Base Station Handover Prediction for Remote Driving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In remote driving scenarios, terminal devices may be handed over to base stations with insufficient communication quality due to increasing communication delays, even when initial delays are minimal, leading to unacceptable performance.
Innovation Solution
A communication system where base stations acquire and notify terminal devices of predicted communication quality information, including delay, for candidate handover destinations, allowing the terminal device to select a base station with sufficient quality, thereby preventing handovers to stations with excessive delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal device performs handover to base stations based on conventional methods, then the handover process can be executed, but the communication quality becomes insufficient due to increasing communication delays
Solution Approach 1:
The base station acquires and notifies the terminal device of predicted communication quality information for candidate handover destinations before the actual handover occurs. This allows the terminal device to proactively select a base station with sufficient communication quality, preventing handovers to stations with excessive delays and ensuring reliable communication is maintained throughout the handover process.
2Loss of time
If the terminal device connects to base stations with sufficient communication quality, then the communication delay is minimized, but the handover selection process becomes more complex
Solution Approach 1:
The base station acts as an intermediary by acquiring predicted communication quality information for candidate handover destinations and notifying the terminal device. This intermediary role simplifies the terminal device's decision-making process, as the base station has already evaluated and provided the communication quality metrics, allowing the terminal device to select the optimal base station without complex evaluation algorithms.

AI summary
First information indicating one or more other base stations, which are candidates for a handover destination of a terminal device in connection from a base station, is acquired, and second information regarding communication quality predicted in a communication through the other base station for each of the one or more other base stations is acquired based on the first information; and third information regarding the communication quality for at least one of the one or more other base stations is notified to the terminal device based on the second information. The third information is used to control a handover of the terminal device.
