Data transmission/reception method
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.
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.
