摘要：The present invention relates to a mobile communication system, and moreparticularly, to a method for a handoff of a medium rate data call in a mobile

communication system. In the present invention, if the pilot strength of the BTS in the

active set to which a SCH is not allocated is smaller than the pilot strength of the BTS towhich the SCH is not allocated for a predetermined period of time, the mobile stationtransmits the corresponding information to the base station by means of a PSMM, andthe base station performs a handoff of the SCH resource according to the PSMM. Inaddition, if the base station receives the PSMM from the mobile station, whether or notthe SCH is allocated is determined using the pilot strength of the corresponding BTS,reference threshold, and TADD. Therefore, frequent handoffs are prevented and theload of the mobile station is reduced because there is no need to compute a SCH

reference threshold at every handoff request. Moreover, it is made possible to maintain aconstant data rate and provide a medium rate data service by performing a handoff of anavailable SCH.
