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.

Claims

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.

2. The method of claim 1, wherein the step of occupying the forward packet traffic channel assigns the forward packet traffic channel in the next slot period subsequent to the slot period, in which the assignment information is transmitted in the packet control.

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

releasing the occupation of the forward packet traffic channel after receiving the packet data and transitioning to the packet idle state.

4. The method of claim 3, wherein the terminal assigns the forward packet traffic channel in the next slot period subsequent to the slot period in which the information of the forward traffic channel is transmitted in the packet control channel in the step of the forward packet traffic channel occupation.

5. A method for providing a reverse packet data service of a base station having a reverse 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 in a packet idle state, the packet control message including information for assigning a slot period of the reverse packet traffic channel and a terminal to be assigned the reverse packet traffic channel;

occupying the reverse packet traffic channel in the assigned slot period and receiving the packet data via the occupied slot period of the reverse packet traffic channel; and

releasing the occupation of the reverse packet traffic channel after receiving the packet data and transitioning to the packet idle state.

6. The method of claim 5, wherein the step of transmitting information assigning the slot period of the reverse packet traffic channel further transmits the power control information for controlling the transmitting power level of the terminal assigned in the packet control channel.

7. The method of claim 5, wherein the reverse packet traffic channel is assigned in the next slot period subsequent to the slot period in which the assignment information is transmitted in the packet control channel in the step of the reverse packet traffic channel assignment.

8. A method for providing a reverse packet data service of a terminal having a reverse 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 a packet control channel in a packet idle state, the packet control message including information for assigning a slot period of the reverse packet traffic channel and a terminal to be assigned the reverse packet traffic channel;

occupying the reverse packet traffic channel in the assigned slot period and transmitting the packet data via the occupied slot period of the reverse packet traffic channel; and

releasing the occupation of the reverse packet traffic channel after transmitting the packet data and transitioning to the packet idle state.

9. The method of claim 8, wherein the step of transmitting the packet data further comprises controlling transmitting the power of the packet data to be transmitted by a power control command received from the packet control channel.

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
