Abstract: PURPOSE: An enhanced MAC(Medium Access Control sub-layer) control apparatus and method of a mobile communication system, particularly for effectively allocating a radio channel by controlling a MAC layer, are provided to effectively use radio resources by analyzing characteristics information according to an application pattern of data transmitted through a logical channel and traffic generation frequency, and then dynamically allocating a transmission channel. CONSTITUTION: When data is inputted from a logical channel(S100), a MAC-d monitors an application pattern and a traffic frequency pattern of the inputted data and detects corresponding characteristics information(S110). The MAC-d records the characteristics information in a recording unit, calculates or extracts statistical characteristics information by a certain period, and outputs it to a controller(S120). The controller analyzes the size or the amount of the data and the traffic frequency(S130) and compares them with pre-set threshold values to determine whether the amount of data and the traffic frequency are greater than the threshold values(S140). If the amount of data and the traffic frequency are smaller than the threshold values, the controller performs a dynamic mapping to allocate a common channel or a shared channel with a low data transfer rate(S150). If the amount of data is greater or if the amount of data is smaller but the traffic frequency is greater, the controller performs a dynamic mapping to allocate a dedicated channel with a high data transfer rate(S160). The data of the logical channel is transmitted through the mapped transport channel to a mobile terminal(S170).
