There is disclosed a handoff control method for registering a CDMA mobile station in such a way that battery power wastage is prevented if successive attempts to register the station fail. If it is judged that registration fails (step S 106 ), idle handoff is inhibited (step S 107 ). The mobile station shifts to a registration-waiting sleep mode (step S 108 and state ST 10 ) in which the sending and receiving operation of the mobile station is paused for a given time. When a sleep timer that is set in the step S 108 times out, registration is resumed under certain conditions. On resumption, a new pilot signal is acquired.
