Abstract

During data transmission to a remote unit (113) utilizing a supplemental, high-speed data channel (105), data transmission stops due to all data being communicated to the remote unit (113) or because a time period for transmission has expired. In the situation where all data has been transmitted to the remote unit (113) the remote unit (113) will delay dropping the data channel (105) for a predetermined period of time. In the situation where a time period for transmission has expired, the remote unit (113) will continue transmitting into a frame assigned to another remote unit.

Claims

1. A method for data transmission within a wireless communication system, the method comprising the steps of:

transmitting data over a wireless data channel at a data rate;

determining that no more data needs to be transmitted; and

delaying dropping the data channel for a time period based on the data rate.

2. The method of claim 1 wherein the step of transmitting data over the wireless data channel comprises the step of transmitting data over a Code Division Multiple Access (CDMA) Supplemental Channel.

3. The method of claim 1 wherein the step of delaying dropping the data channel for a time period based on the data rate comprises the step of delaying dropping the data channel for a time period, wherein the time period is proportional to the data rate.

4. A method for data transmission within a Code Division, Multiple Access (CDMA) wireless communication system, the method comprising the steps of:

operating a data transmitter in a CDMA Active state;

determining that no more data needs to be transmitted over a CDMA supplemental channel;

prior to operating the data transmitter in a Control Hold state, delaying transition to the Control Hold state for a period of time, wherein the period of time is based on a data rate; and

operating the data transmitter in a Control Hold state.

5. The method of claim 4 wherein the step of operating the data transmitter in the CDMA Active state comprises the step of transmitting via a dedicated control channel and a CDMA supplemental channel.

6. The method of claim 5 wherein the step of operating the data transmitter in the Control Hold state comprises the step of transmitting via a dedicated control channel only.

7. An apparatus comprising:

channel circuitry for transmitting data; and

a timer coupled to the channel circuitry, wherein the timer delays deactivation of the channel circuitry after data transmission for a period of time, wherein the period of time is based on a data rate.

8. The apparatus of claim 7 wherein the period of time is proportional to the data rate.

9. The apparatus of claim 7 wherein the channel circuitry comprises CDMA fundamental channel circuitry.

10. A method for data transmission within a wireless communication system, the method comprising the steps of:

transmitting data to a first receiver over a first plurality of frames on a data channel, wherein the first plurality of frames are assigned to the first receiver;

transmitting data to the first receiver, over a frame on the data channel for a period of time, wherein;

the frame is assigned to a second receiver;

the frame is not part of the first plurality of frames;

the period of time is based on a time to transfer from a hold state to an

active state; and

transmitting second data to a second receiver over the frame.

11. A method for data transmission within a wireless communication system, the method comprising the steps of:

receiving data via a first receiver from over a first plurality of frames on a data channel, wherein the first plurality of frames are assigned to the first receiver;

receiving data via the first receiver, over a frame on the data channel for a period of time, wherein;

the frame is assigned to a second receiver;

the frame is not part of the first plurality of frames; and

the period of time is based on a time to transfer from a hold state to an active state.

12. An apparatus for data transmission within a wireless communication system, the apparatus comprising:

means for transmitting data over a first plurality of frames on a data channel, wherein the first plurality of frames are assigned to the first receiver;

means for transmitting data over a frame on the data channel for a period of time, wherein;

the frame is assigned to a second receiver; and

the frame is not part of the first plurality of frames.

13. A method for data transmission within a General Packet Radio Service (GPRS) communication system, the method comprising the steps of:

establishing a temporary block flow (TBF) between a transmitting device and a receiving device to transmit data over a data channel;

determining that no more data needs to be transmitted to the receiving device; and

delaying termination of the TBF by transmitting dummy data over the data channel.

14. A base station or a mobile unit comprising:

means for establishing a temporary block flow (TBF) between a transmitting device and a receiving device to transmit data over a data channel;

means for determining that no more data needs to be transmitted to the receiving device; and

means for delaying termination of the TBF by transmitting dummy data over the data channel.
