Parallel Cell Reselection Evaluation for Mobility State Adaptation

The patent applies parameter changes by dynamically adjusting mobility parameters (such as measurement filtering coefficients, time-to-trigger values, and hysteresis margins) based on the determined mobility state of the wireless terminal. The base station configures different sets of parameters for different mobility states (e.g., low speed, medium speed, high speed), allowing the system to optimize mobility performance for each state without permanently maintaining complex multi-process evaluation structures. This resolves the contradiction by making the system adaptable rather than statically complex.

The patent implements dynamics by making the evaluation process configuration dynamic rather than static. The base station determines the mobility state of the wireless terminal (e.g., through measurement reports containing speed information or through network-side speed estimation) and dynamically configures the appropriate number and type of parallel evaluation processes. When high mobility performance is needed (high speed scenarios), more processes are activated; when not needed, fewer processes run, reducing power consumption. This dynamic adaptation resolves the contradiction between maintaining mobility performance and reducing energy usage.

The patent applies segmentation by dividing the mobility parameter configuration into multiple distinct sets, each optimized for specific mobility states (e.g., low speed, medium speed, high speed). Instead of using a single configuration for all scenarios, the system segments the parameter space and selects the appropriate segment based on the current mobility state. This allows optimal performance in each speed range while maintaining adaptability across all ranges, resolving the contradiction between efficiency in normal scenarios and versatility across all scenarios.
