Method for handling of soft hand-off in CDMA mobile communication system

摘要

In the present invention, a code division multiple access mobile communication system for minimizing inter-sectoral handoff failure and call drop (call drop) by matching information of an active pilot between a higher processor and a lower processor during soft handoff is performed. The present invention relates to a method for processing soft handoff in a mobile communication system comprising a base station with CE and BCP and a control station with TSB and CCP. Determining whether one drop or two drops are received in one active area (Alpha) (Beta) (Gamma) receiving the soft handoff instruction message from the coder and the selector bank, and if the result of the determination in the step is one drop or two drops, Determining whether the active pilot is a drop pilot; and the determination result of the step is that the active pilot is not a drop pilot. And performing a handoff completion report to the TSB by completing one drop or two drops, and transmitting a Not Acknowledge (NAK) message to the TSB when the active pilot is a drop pilot.
