User Equipment Cell Reselection for Mobile IAB Frequency Priority

The patent applies local quality by differentiating the frequency priority treatment based on the specific characteristics of mobile IAB cells. Instead of using uniform frequency priority rules for all cells, the system assigns higher priority to frequencies used by mobile IAB cells when certain conditions are met (e.g., when the mobile IAB cell is in a specific state or when reselection criteria are satisfied). This localized differentiation improves communication reliability by ensuring mobile IAB nodes are properly handled during reselection while maintaining simplicity for conventional cells.

The patent implements preliminary action by establishing specific conditions and criteria before the user equipment executes frequency prioritization for mobile IAB cells. The system first determines whether the mobile IAB cell satisfies predetermined reselection criteria (such as signal strength thresholds, cell state conditions, or network configuration parameters) before applying higher frequency priority. This preliminary verification prevents the equipment from arbitrarily prioritizing mobile IAB frequencies, thereby avoiding connection to unsuitable cells while maintaining communication stability.

The patent applies dynamics by making the cell reselection procedure adaptive rather than static. The system dynamically adjusts frequency priority assignments based on real-time conditions such as the current state of mobile IAB cells, signal quality measurements, and network configuration. When mobile IAB cells are detected to be in favorable conditions (e.g., stable connection state or appropriate signal strength), the system dynamically increases their frequency priority to maintain service continuity. This dynamic adjustment prevents service disruptions caused by mobile IAB node mobility while keeping the overall procedure relatively simple through automated decision-making.
