SOFT SWAP HANDOFF FOR CDMA CELLULAR SYSTEM

摘要

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