Abstract
An apparatus performs a handoff considering a moving speed of a mobile station in a mobile communication system. A searcher calculates energy of every PN phase in a given search window and reports a detected PN phase to a controller. The controller then determines a moving direction and a moving speed of a mobile station depending on the detected PN phase and a previously detected PN phase, and adaptively determines a pilot received strength threshold used to perform a handoff depending on the determined moving direction and moving speed of the mobile station.
