Abstract
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), idle handoff is inhibited (step S). The mobile station shifts to a registration-waiting sleep mode (step Sand state ST) 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 Stimes out, registration is resumed under certain conditions. On resumption, a new pilot signal is acquired.
