A base station for a radio communication system suitable for use if a radio data communication network is configured using a mobile radio terminal has a base station apparatus for a radio communication system which communicates with a mobile radio terminal over a radio line. The base station apparatus for a radio communication system has a voice communication processing system for processing voice signals and a data communication processing system for processing data signals. The data communication processing system has a low-speed modulating/demodulating unit for conducting a modulating/demodulating process on data signals at a processing speed lower than a processing speed of the voice communication processing system, thereby dividing a way of use of a communication channel and a control channel into data communication purpose and voice communication purpose upon data communication so as to increase an efficiency of utilization of the line.
