Abstract: This disclosure provides an apparatus and a method for controlling a soft handover rate. A distribution of cell signal strengths that is received by user equipment is obtained through analysis of measurement reports of the user equipment, a mapping relationship between soft handover parameters and air interface quality is determined, and the soft handover parameters are adjusted according to the mapping relationship. Adjusting soft handover parameters of a cell according to signal quality of the cell can reduce a soft handover rate and increase a capacity on a premise that communication quality is maintained. Further, after the soft handover rate is adjusted according to the air interface quality, monitoring of the air interface quality, and by modifying specific cell handover parameters, communication quality of the user equipment that performs a soft handover is maintained, and a balance between increasing the system capacity and maintaining the communication quality is achieved.

Abstract: A system for iteratively matching a plurality of spatiotemporal trajectories of a plurality of users is provided. The system comprises at least one processor, being configured for: receiving a plurality of first spatiotemporal trajectories and a plurality of second spatiotemporal trajectories each generated based on location data. Using a quality classifier for classifying the plurality of first spatiotemporal trajectories into first low quality trajectories and first high quality trajectories and the plurality of second spatiotemporal trajectories into second low quality trajectories and second high quality trajectories the processor identifies a plurality of high quality trajectories pairs and a plurality of low quality pairs; associating to each pairs with a confidence value indicative of a disparity; adjusting the confidence values and re-inputting into the quality classifier all spatiotemporal trajectories which are part of a low quality pair or a high quality trajectories pair whose adjusted confidence value is below the threshold.
