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,

wherein the first discontinuous reception period is a long DRX period and the second discontinuous period is a short DRX period,

wherein the downlink data is an RLC (Radio Link Control) AMD (Acknowledged Mode Data) PDU (Protocol Data Unit) received via an HS-DSCH (High-Speed Downlink Shared Channel),

wherein the response message is an RLC ACK (Acknowledgement) transmitted via a RACH (Random Access Channel),

wherein all the steps are performed when the terminal is in a CELL_PCH state.

2. 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.

3. 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,

wherein the first discontinuous reception period is a long DRX period and the second discontinuous period is a short DRX period,

wherein the downlink data is an RLC (Radio Link Control) AMD (Acknowledged Mode Data) PDU (Protocol Data Unit) transmitted via an HS-DSCH (High-Speed Downlink Shared Channel),

wherein the response message is an RLC ACK (Acknowledgement) received via a RACH (Random Access Channel),

wherein all the steps are performed when the terminal is in a CELL_PCH state.

4. The method of claim 3, 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.
