Network Node Cell Range Expansion for Wireless Handover Control

The patent applies dynamics by making the cell range expansion configuration mode dynamic rather than static. The network node determines whether to apply cell range expansion in connected mode or idle mode based on real-time data communication amount estimates. When data communication amount is high, connected mode expansion is applied; when low, idle mode expansion is applied. This dynamic adaptation resolves the contradiction by optimizing handover efficiency while maintaining coverage area.

The patent applies parameter changes by dynamically adjusting the cell range expansion configuration based on the data communication amount parameter. The network node estimates the data communication amount and uses this parameter to determine whether to activate cell range expansion and in which mode (connected or idle). This parameter-driven approach allows coverage area to be extended while controlling interference levels by selectively applying expansion only when beneficial.

The patent applies feedback by implementing a closed-loop system where the network node continuously monitors data communication amount, determines appropriate cell range expansion configuration, and adjusts measurement report requirements accordingly. The network node estimates data communication amount from uplink signals and uses this feedback to dynamically configure measurement reports, reducing unnecessary handovers while optimizing radio resource utilization through adaptive control.
