Device and method for controlling channel access by access slot reserving in a mobile communication system

摘要

A channel access control device and method are provided in which a base station reserves a specific access slot for a mobile station when the mobile station has data to transmit which exceeds one frame in length. The base station receives channel access information from the mobile station via a reverse access channel; and examines a length of transmission data, included in the received channel access information, to determine whether the transmission data continues in at least one succeeding frame; and reserves a specific access slot on the reverse access channel for the mobile station via a forward access channel when the data continues in the at least one succeeding frame.
