Abstract: An apparatus for increasing data transmission efficiency in an international mobile telecommunication-2000 (IMT-2000) base station controller includes a) user message determining unit for receiving a user message from an exterior; determining whether the user message is control data or traffic data; and transmitting the control data or the traffic data; b) channel interface unit for receiving the control data or the traffic data from the user message determining unit and transmitting the control data or the traffic data; c) traffic data controlling unit for receiving the traffic data and information about quantity of data and transmitting the traffic data; d) storage unit for storing the control data or the traffic data; and e)storage managing unit for measuring quantity of data stored in the storage means and transmitting measured quantity information.

Abstract: Disclosed is a method for transmitting wireless packet data in a mobile communication system, which can provide a high-quality wireless packet data service at a lower cost by enabling a common data channel, which is used to transmit bursting data to terminals, to function as a dedicated data channel. The method for transmitting wireless packet data in the mobile communication system comprises the steps of: initializing a call processor within a base station, receiving a setup message from the terminals and simultaneously receiving a time table assignment request message from the control station; generating a packet data call instance in response to the received time table assignment request message; updating a time table and generating a radio burst protocol (RBP) instance; and transmitting the slot information message through the paging channel to the terminals and transmitting a time table assignment completion message to the control station.
