Engineering Contradiction Analysis
1Reliability
If handover is executed when wireless quality information decreases below a threshold, then switching between radio base stations is achieved, but communication state deterioration cannot be avoided and reliable wireless communication cannot be realized
Solution Approach 1:
The system performs preliminary actions by predicting future handover execution timing and estimating candidate radio base stations before actual handover conditions are met. This allows the system to proactively switch frequency bands in advance, preventing communication state deterioration rather than reacting after quality drops below threshold.
Solution Approach 2:
The system dynamically adjusts frequency band switching based on predicted handover timing and estimated candidate base stations. Instead of using a fixed threshold-based handover approach, the system adapts frequency band selection to dynamic predictions of future communication conditions, enabling reliable communication despite unstable radio environments.
2Reliability
If frequency band switching is performed based on current radio quality, then interference can be avoided, but prediction of future communication states and stable communication in unstable environments cannot be achieved
Solution Approach 1:
The system performs preliminary frequency band switching based on predicted future handover timing rather than waiting for current radio quality measurements to indicate problems. By using prediction information to proactively switch frequency bands before actual handover occurs, the system ensures stable communication while minimizing the time needed for quality assessment.
