Abstract

A method for receiving data from a radio network by a terminal includes: receiving downlink data while the terminal operates according to a first discontinuous period; transmitting a response message with respect to the downlink data; and operating according to a second discontinuous period after transmitting the response message.

Claims

1. A method for receiving data from a radio network by a terminal comprising:

receiving downlink data while the terminal operates according to a first discontinuous reception period;

transmitting a response message with respect to the downlink data; and

operating according to a second discontinuous reception (DRX) period after transmitting the response message.

2. The method of claim 1, wherein the first discontinuous reception period is a long DRX period, and the second discontinuous period is a short DRX period.

3. The method of claim 1, wherein the downlink data is an RLC (Radio Link Control) AMD (Acknowledged Mode Data) PDU (Protocol Data Unit), and the downlink data is received via an HS-DSCH (High-Speed Downlink Shared Channel).

4. The method of claim 1, wherein the response message is an RLC ACK (Acknowledgement).

5. The method of claim 1, wherein the terminal is in a CELL_PCH state.

6. The method of claim 1, further comprising;

activating a timer with respect to the second discontinuous reception period after the downlink data is received; and

operating according to the first discontinuous reception period when the timer expires.

7. A method for transmitting data to a terminal by a radio network, comprising:

transmitting downlink data while operating according to a first discontinuous period;

receiving a response message with respect to the downlink data; and

operating according to a second discontinuous period after the response message is received.

8. The method of claim 7, wherein the first discontinuous period is a long DRX (Discontinuous reception) period, and the second discontinuous period is a short DRX period.

9. The method of claim 7, wherein the downlink data is an RLC (Radio Link Control) AMD (Acknowledged Mode Data) PDU (Protocol Data Unit), and the downlink data is received via an HS-DSCH (High-Speed Downlink Shared Channel).

10. The method of claim 7, wherein the response message is an RLC ACK (Acknowledgement).

11. The method of claim 7, wherein the terminal is in a CELL_PCH state.

12. The method of claim 7, further comprising;

activating a timer with respect to the second discontinuous period after the response message is received; and

operating according to the first discontinuous period when the timer expires.
