Abstract
A mobile station is provided which does not cause a reduction in the speech transmission capacity. Branches receive radio signals from base stations and operate independently of one another. A branch operation control section controls the operation of the individual branches to detect a destination-side base station based on the reception levels of signals from surrounding base stations, to cause part of the branches to establish synchronization of spreading code and carrier frequency with respect to the destination-side base station while causing the other part of the branches to maintain communication with a departure-side base station after the destination-side base station is detected, and to cut off the communication with the departure-side base station after the synchronization is established.
