Handover apparatus and method of portable terminal

摘要

A handover method of a portable terminal includes checking communication quality during a movement of the portable terminal (301) in a service coverage area of a serving cell; when the communication quality is lower (302) than preset communication level, determining one or more neighbor cells exceeding the preset communication level (303) by considering a travel speed of the portable terminal; selecting (304) a neighbor cell from the determined neighbor cells; and performing a handover (305) to the service coverage area of the selected neighbor cell.
