Abstract: PURPOSE: A method for controlling a handoff, relating a high speed data cell in a code division multiple access(CDMA) mobile communication system is provided to control the handoff of the high speed data cell using a multi speech channel when the mobile communication system performs a high speed data service in a CDMA mobile communication system, so as to prevent a shortage of a system capacity caused by handoff execution. CONSTITUTION: A mobile station allocates a second fundamental channel between a mobile station and a target base station, on the basis of a pilot strength measurement received from the target base station. The mobile station performs an ADD handoff relating to a first fundamental channel which is previously allocated from a first mobile station and a serving base station, and the allocated second fundamental channel. After the ADD handoff of the fundamental channel is completed, a serving base station decides an ADD handoff starting point toward many supplemental channels. From the decided starting point, the serving base station executes the ADD handoff toward the supplemental channels(S109).
