摘要： There is provided a data transmitting method in a CDMA system. In the CDMA system, a control hold state and an active state are set for data transmission between a mobile station and a base station. The control hold state is entered to transmit a control signal on a dedicated control channel and the active state is divided into a low rate transmission substate for transmitting a small amount of data on the dedicated control channel or/and a fundamental channel and a high rate transmission substate for transmitting a large amount of data on a supplemental channel and on at least one of the dedicated control channel and the fundamental channel. When a large amount of user data is generated in the mobile station, the mobile station generates a supplemental channel request message including supplemental channel request information needed to transit from the control hold state to the high rate transmission substate without interposition of the low rate transmission substate and state transition information needed to transit from the control hold state to the active state, and transmits the supplemental channel request message to the base station.

摘要： A reverse data rate determining method in a mobile communication system for high data rate transmission such as an HDR system, wherein an AN (Access Network) within a cell calculates a total load of a reverse link by measuring a total energy of a reverse link from ATs (Access Terminals) within the cell. The AN calculates the share of each AT in the total reverse link load. If the load share of an AT is greater than a threshold predetermined individually for the AT, the AN determines that the AT should reduce its data rate.

摘要： A method for performing data communication in a mobile communication system is disclosed. The method serves to increase channel efficiency by connecting and releasing channels in accordance with the presence/absence of control and traffic data transmitted during packet data communications. Transmission power and mobile terminal battery power are conserved by controlling outputs of a dedicated control channel and a pilot channel when data transmission is discontinued temporarily during data communications. The mobile communication system includes an active state in which user data is transmitted through a dedicated traffic channel and control messages are transmitted through a dedicated control channel. In accordance with the method, a transition is made from the active state to a first control hold state when there is no control or user data to transmit for a first preset time. In the first control hold state, the dedicated traffic channel is released while the dedicated control channel and a reverse pilot channel are maintained. A transition is made from the first control state to a second control hold state when there is no user or control data to transmit for a second preset time. In the second control hold state, which is a resource save sub-state, the transmission outputs of the dedicated control channel and reverse pilot channel are interrupted to conserve power.
