Method and apparatus for providing packet data service in a communication system
First Claim
1. A method for providing a forward packet data service of a base station having a forward packet traffic channel and a packet control channel in a CDMA (Code Division Multiple Access) communication system, comprising the steps of:
- transmitting a packet control message via the packet control channel when generating a packet data to be transmitted in a packet idle state, the packet control message including information for assigning a slot period of the forward packet traffic channel and a terminal to be assigned the forward packet traffic channel;
occupying the forward packet traffic channel in the assigned slot period and transmitting the packet data via the occupied slot period of the forward packet traffic channel; and
releasing the occupation of the forward packet traffic channel after transmitting the packet data and transitioning to the packet idle state.

Abstract
Method and apparatus for providing a packet data service between a terminal and a base station in a mobile communication system includes packet data being transmitted from the terminal (base station) on a reverse (forward) packet traffic channel to the base station (terminal) during a data transmission period; the occupation of the reverse (forward) packet traffic channel is released during a data transmission suspension period; and the base station controls the reverse (forward) packet traffic channel over a packet control channel.

3. A method for providing a forward packet data service of a terminal having a forward packet traffic channel and a packet control channel in a CDMA (Code Division Multiple Access) communication system, comprising the steps of:
-
checking terminal information of a packet control message received via the packet control channel in a packet idle state, the packet control message including information for assigning a slot period of the forward packet traffic channel and a terminal to be assigned the forward packet traffic channel;
occupying the forward packet traffic channel in the assigned slot period and receiving the packet data via the occupied slot period of the forward packet traffic channel, when assigning said terminal itself in the packet control message; and

10. An apparatus for providing a forward packet data service of a base station in a CDMA communication system, comprising:
-
a packet control channel transmitter for transmitting a packet control message;
a forward packet traffic channel transmitter for transmitting a packet data to a designated terminal in an assigned slot period; and
a base station packet controller for generating the packet control message when generating the packet data to be transmitted in a packet idle state, said packet control message including information for assigning the slot period of the forward packet traffic channel and the terminal to be assigned the forward packet traffic channel, assigning the forward packet traffic channel in the assigned slot period, releasing the assigned forward packet traffic channel after transmitting the packet data and transitioning to the packet idle state.
