PURPOSE: A method for multicasting high speed data is provided to simultaneously service the same data in a high speed to person of a group which exists in the same sector. CONSTITUTION: A call processor informs the existence of traffic to corresponding terminals(S101,S102). The terminals of a corresponding group responds through an access through within a uniform time(S103,S104). The call processor waits for the response of the terminals through the access channel during the uniform time, divides the terminals according to a sector, and excepts terminals which does not respond from a multicasting object(S105). The call processor detects current positions of the terminals through access messages transmitted from terminals, and assigns a downlink high speed data channel and an uplink control channel on the basis of the positions of the terminals(S106,S107). The call processor transmits a high speed data packet to the terminals(S108,S109). If an uplink control channel signal is transmitted to from the terminal to a base station, the base station responds to the uplink control channel signal and perform an acknowledgement process(S110,S111).
