Data transmitting method in a CDMA system
First Claim
1. A data transmitting method in a mobile station of a CDMA system where a control hold state and an active state are set for data transmission between the mobile station and a base station, the control hold state being entered for transmitting a control signal on a dedicated control channel and the active state being 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, the method comprising the steps of:
- generating a supplemental channel request message including existing supplemental channel request message fields and state transition information, which is needed to transition from the control hold state to the high rate transition substate without interposition of the low rate transition substate; and
transmitting the supplemental channel request message to the base station.

Abstract
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.

7. A data transmitting method in a base station of a CDMA system where a control hold state and an active state are set for data transmission between a mobile station and the base station, the control hold state being entered for transmitting a control signal on a dedicated control channel and the active state being 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, the method comprising the steps of:
-
generating an extended supplemental channel assignment message including existing supplemental channel assignment message fields and state transition information, which is needed to transition from the control hold state to the high rate transition substate without interposition of the low rate transition substate; and
transmitting the supplemental channel assignment message to the mobile station. - View Dependent Claims (8, 9, 10)
