Abstract:
A method for transmitting a signal from a base station transceiver system (BTS) to a base station controller (BSC) when there is no data transmitted from a mobile station while in discontinuous transmission (DTX) mode, in a mobile communication system, said mobile communication system including said mobile station for transmitting and receiving data in a synchronous mode, said base station transceiver system and said base station controller for controlling said base station transceiver system, the method comprising the steps of:detecting discontinuous transmission (DTX) mode; setting previous power control information to present power control information if discontinuous transmission mode is detected, said previous power control information having been used for power control of the mobile station before detection of discontinuous transmission mode; and transmitting a reverse message including the present power control information to the base station controller over a dedicated channel.
