ABSTRACT:
A method for providing soft swap handoff in a CDMA communication system is provided. The pilot signal strengths of newly detected base stations that are above a predetermined level are compared with those of the base stations presently in active state. If the pilot signal strength of a newly detected base station is above the predetermined level and also stronger than the weakest one among those of the base stations presently in active state by a prescribed value, then the base station controller (BSC) instructs the mobile station to drop the weakest base station among the base stations that are presently in active state.
