    摘要： There is provided a supplemental channel assigning apparatus and method in a mobile communication system. In the supplemental channel assigning method, a mobile station receives a plurality of supplemental channel assignment messages successively from a base station on an existing traffic channel, each of the channel assignment messages having the fields of a start time, a duration, a sequence number for message identification, and a channel identifier for channel identification, and stores the received channel assignment messages in a memory according to the durations and sequence numbers of the channel assignment messages. The mobile station then conducts data communication on a channel corresponding to the channel identifier of a first read channel assignment message for a period between the start time and the end of the duration set in the read channel assignment message and then on a channel corresponding to the channel identifier of a next read channel assignment message for a period between the start time and the end of the duration set in the next channel assignment message, the start time of the next channel assignment message being set to or after the end of the data communication according to the first read channel assignment message.

    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： Disclosed is a method for assigning packet data to be transmitted to a radio packet data channel of a base station system in response to a packet traffic transmission request for a plurality of mobile stations in a mobile communication system. The method comprises collecting the packet traffic transmission requests of the radio packet data channel for the mobile stations; selecting at least one of the mobile stations from the collected packet traffic transmission requests; transmitting to the selected mobile station a channel assignment message including information about a data rate, data transmission durations of the radio packet data channel and start points of the data transmission durations for the selected mobile station; and transmitting the packet data to the selected mobile station at the start points of the data transmission durations at the data rate.

    摘要： A device and method for communicating voice data in packet form in a mobile communication system. In the packet voice data communication method, upon generation of voice data, a packet voice channel is assigned, and an active state (1015) is entered where packetized voice data is transmitted on the voice channel. If there is no voice data for a predetermined time period while in the active state (1015), the assigned voice channel is released, and an inactive state (1013) is entered where no voice data is transmitted. If the next voice data is generated while in the inactive state (1013), the voice channel active state is entered where a voice channel is assigned to transmit the next voice data, and the voice data is transmitted.
