Abstract

A cellular telephone (100) that searches for a destination base station in accordance with a handoff instruction receives a soft handoff instruction or a hard handoff that is able to specify a first search window size. When the hard handoff instruction is received, a search block (70) is controlled so that a window control block (83) searches for pilot signals from neighboring base stations using a search window having a size larger than one of the first search window size and a third search window size that is used when the soft handoff instruction is received.
