METHOD FOR SUPPORTING DISCONTINUOUS TRANSMISSION MODE IN BASE STATION IN MOBILE COMMUNICATION SYSTEM

摘要

PURPOSE: A method for supporting a discontinuous transmission mode in a base station of a mobile communication system is provided to transceive a forward and reverse frame through a dedicated control channel between a base station controller and a base station transceiver system. CONSTITUTION: A mobile communication system includes a mobile station for transceiving data in a predetermined period, a base station transceiver system, and a base station controller for controlling the base station transceiver system. Upon detection of the discontinuous transmission mode, it is determined what type of frame was last transmitted from the mobile station, and the present power control information is set according to the type of frame. If it is a null frame, the base station transceiver system sets previous power control information that the base station transceiver system has used for power control of the mobile station before detection of discontinuous transmission mode, to present power control information. Thereafter, the base station transceiver system transmits a reverse message including the present power control information to the base station controller over a dedicated control channel. If there is data being transmitted between the mobile station and the base station transceiver system at the time where the discontinuous transmission mode is detected, the previous power control information is set to the present power control information.
