Problems solved by technology

[0006] However, even if there is no protocol data unit (PDU) transmitted from the base station to the terminal during the listening window of the sleep mode, the power level of the terminal is increased during the set window, resulting in unnecessary power consumption

[0058] II. First Embodiment (ELWTF=0)

[0059] In the case where ELWTF is set to "0" in Table 1 and Table 2, if the PDU in the buffer is the last PDU to be sent to the terminal during the listening window or listening window extension, the base station does not send an advance message to the terminal. Listen for window termination indications.

[0060] In this case, the terminal can receive a PDU from the base station to operate a timer (TMS), and if the TMS times out, terminate the listening window early and enter the sleep window.

[0061] figure 2 is a view illustrating an early listening window termination operation of a terminal according to an embodiment of the present invention in a case where ELWTF is set to '0'.

[0062] In the case that there is a packet to be sent to the terminal, the base station sends a positive TRF-IND message to the listening window (S201) to inform the terminal that a service has been generated, and sends a packet to the terminal, thereby op...

Abstract

Disclosed herein relates to a sleep mode operation method, and the sleep mode operation method according to the present invention may include transmitting a sleep request message for requesting sleep mode switching to a base station; receiving a sleep operating parameter including a sleep cycle and a listening window from the base station; referring to the sleep operating parameter to switch to a sleep mode; receiving a traffic indication message indicating that traffic is generated from the base station; receiving traffic from the base station during the listening window while at the same time operating a timer; and early terminating the listening window to enter into a sleep window if the timer operation is expired according to the traffic reception prior to terminating the listening window.

Description

technical field [0001] The present invention relates to a sleep mode operation method and device, and more particularly, to a sleep mode operation method and device capable of early termination of a listening window in the sleep mode to enhance the effect of power reduction in a terminal. Background technique [0002] Compared with other systems, in the broadband wireless mobile communication system, since the mobility of the terminal should be considered, the issue of power consumption in the terminal may be a rather important element. A sleep mode operation between a terminal and a base station has been proposed as one of such methods for minimizing power consumption in the terminal. [0003] In conventional sleep mode operation, if there is no longer traffic to be transmitted to and / or received from the base station when communication with the base station is performed in active mode, the terminal requests to enter sleep mode and receives the request from the base station...
