Base Station Delay Prediction for Wireless Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, particularly in remote vehicle operation, maintaining low communication delays during handovers between base stations is challenging due to the movement of terminal apparatuses, leading to potential disruptions in communication quality and accuracy.
Innovation Solution
A base station acquires and notifies terminal apparatuses of predicted communication delays from other base stations, allowing the terminal apparatus to select handover destinations with minimal delays and optimal wireless quality, thereby ensuring continuous and accurate remote operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal apparatus carries out handover process frequently to maintain connection during vehicle movement, then the connection reliability is improved, but the communication delay increases and operation accuracy deteriorates
Solution Approach 1:
The base station predicts communication delays for other base stations before handover occurs and notifies the terminal apparatus in advance. This allows the terminal to proactively select the optimal target base station based on predicted delays, rather than reactively switching after connection issues arise. The preliminary notification of delay information enables ahead-of-time decision-making that prevents delay accumulation during handover transitions.
2Loss of time
If the terminal apparatus maintains connection via a single base station, then the communication delay is reduced, but the connection reliability deteriorates during vehicle movement
Solution Approach 1:
The system dynamically adapts the handover strategy based on predicted communication delays. Instead of using fixed handover thresholds, the terminal apparatus uses the notified delay information to dynamically adjust which base station to connect to, ensuring optimal balance between delay minimization and connection reliability. The base station continuously updates delay predictions and notifications, allowing the system to respond dynamically to changing vehicle positions and network conditions.
3Duration of action of stationary object
If the terminal apparatus performs handover to maintain network connection, then the connection continuity is improved, but the operation accuracy deteriorates due to increased communication delays
Solution Approach 1:
The base station provides predicted communication delay information to the terminal apparatus before handover occurs, enabling the terminal to pre-select the optimal target base station that will maintain both connection continuity and operation accuracy. This preliminary information allows the terminal to choose a target base station with predicted delays within acceptable thresholds, ensuring that handover maintains connection continuity without sacrificing operation accuracy.

AI summary
A base station that includes a memory for storing computer readable code and a processor operatively coupled to the memory is described herein. The processor is configured to acquire other base station delay information, which is information associated with communication delays predicted for communications between the other base stations and a terminal apparatus. The processor is further configured to notify the terminal apparatus of the acquired other station delay information. The terminal apparatus acquires the other station delay information from the base station.
