ABSTRACT:
A mobile communication system includes a medium access control (MAC) layer that supports an idle state in which no downlink and uplink dedicated control channel and dedicated traffic channel exists and also supports an active state in which the downlink and uplink dedicated control channel and dedicated traffic channel exist. The MAC layer controls transitioning to a contention state and then transitioning from the contention state to the active state through contention-based access, if there is transmission data in the idle state; transitioning to a fast access state or a slow access state according to priority of the data if there is no transmission data in the active state for a preset time; transitioning to the active state through contention-free-based access if there is transmission data in the fast access state; and transitioning to the active state through contention-free-based access if there is transmission data in the slow access state.
