CONTROL METHOD OF HANDOVER TRAFFIC SERVICE IN OVERLAY SYSTEMS AND CONTROL APPARATUS THEROF

摘要

The present invention relates to a control method of handover traffic services in a multi-cell environment and a controller thereof. According to the exemplary embodiment of the present invention, a priority for selecting a cell on request for the handover traffic service is determined by considering user preferences and status of neighboring cells, and an optimized cell is determined according to the determined priority. The priority is readjusted to select a second optimized cell when the optimized cell is not selected. That is, quality of service (QoS) is improved by preferentially performing the handover and selecting communication system with various characteristics according to the user preferences in the multi-cell environment.
