Abstract
A multiple access control method for guaranteeing a QoS requirement is disclosed. The method includes the steps of a first step in which the random access channel is separated into a plurality of sub-slots, and one of the thusly separated sub-channels is designated as a forced collision sub-slot and is shared for a mobile station which is sensitive to a reservation delay time, and a second step in which capacity-back (CB) sub-slots are designated one-by-one with respect to the mobile station, which is sensitive to the reservation delay time in the next slot when a collision occurs in the designated forced sub-slot and a reservation request is performed without a predetermined competition.
