Abstract

Disclosed herein relates to a sleep mode operation method, and the method of updating a sleep mode operation according to the present invention may include receiving a service flow configuration request (DSx-REQ) message including a service flow parameter for service flow configuration and a sleep cycle ID (SCID) for changing a sleep mode according to the service flow configuration from a base station during a sleep mode listening window; transmitting a service flow configuration response (DSx-RSP) message including the SCID; configuring the service flow according to the service flow identifier; and changing an SCID to the SCID for updating the sleep mode operation.

Claims

1. A method of updating, by a terminal, a sleep mode parameter in a wireless communication system, the method comprising:

receiving, from a base station, an unsolicited sleep response (SLP-RSP) message, which initiates update of a sleep mode parameter and includes a sleep cycle identifier (SCID) and a start frame number, the SCID indicating a new sleep cycle setting, the start frame number indicating a frame that the new sleep cycle setting is applied;

applying the new sleep cycle setting at the frame indicated by the start frame number by updating the SCID included in the unsolicited sleep response (SLP-RSP) message; and

transmitting, to the base station, an acknowledgement (ACK) message as a response to the unsolicited sleep response (SLP-RSP) message,

wherein the SCID has a size of 4 bits,

wherein the start frame number represents 6 least significant bits of a frame number, and

wherein the start frame number indicates a start frame number for first sleep window.

2. A terminal in a wireless communication system, the terminal comprising:

a receiver for configured for receiving, from a base station, an unsolicited sleep response (SLP-RSP) message, which initiates update of a sleep mode parameter and includes a sleep cycle identifier (SCID) and a start frame number, the SCID indicating a new sleep cycle setting, the start frame number indicating a frame that the new sleep cycle setting is applied;

a controller configured for applying the new sleep cycle setting at the frame indicated by the start frame number by updating the SCID included in the unsolicited sleep response (SLP-RSP) message; and

a transmitter configured for transmitting, to the base station, an acknowledgement (ACK) message as a response to the unsolicited sleep response (SLP-RSP) message,

wherein the SCID has a size of 4 bits,

wherein the start frame number represents 6 least significant bits of a frame number, and

wherein the start frame number indicates a start frame number for first sleep window.
