Embodiment 1

[0037] Embodiment 1: An embodiment in which a terminal in DRX state performs air conditioning through HS-SCCH

[0038] figure 1 It is a flow chart of maintaining the DRX state when the terminal in the DRX state is applied to the air conditioner after applying the present invention.

[0039] Step 101: The network side configures HS-SCCH DRX parameters to the UE and the UE enters the CELL DCH state and starts the HS-SCCH inactive timer;

[0040] The length of the HS-SCCH inactivity timer is configured by the network side in the parameter Inactivity_Threshold_for_HS_SCCH_DRX_cycle of the HS-SCCH DRX.

[0041] Step 102: the base station (Node B, NB for short) sends the HS-SCCH to the UE, instructing the UE to receive downlink packet data;

[0042]Step 103: The UE restarts the HS-SCCH inactivity timer after receiving the HS-SCCH scheduling;

[0043] The UE determines whether the HS-SCCH is scheduled for the terminal by determining whether the high-speed downlink shared channel r...

Embodiment 2

[0053] Embodiment 2: An embodiment in which a terminal not in the DRX state performs air conditioning through HS-SCCH

[0054] figure 2 It is a flow chart of maintaining the DRX state when the terminal is not in the DRX state after the application of the present invention when the air conditioner is turned off.

[0055] Step 201: The network side configures HS-SCCH DRX parameters to the UE and the UE enters the CELL_DCH state and starts the HS-SCCH inactivity timer;

[0056] The length of the HS-SCCH inactivity timer is configured by the network side in the parameter Inactivity_Threshold_for_HS_SCCH_DRX_cycle of the HS-SCCH DRX.

[0057] Step 202: the base station sends the HS-SCCH to the UE, instructing the UE to receive downlink packet data;

[0058] Step 203: The UE restarts the HS-SCCH inactivity timer after receiving the HS-SCCH scheduling;

[0059] Step 204: UE receives HS-DSCH (High Speed ​​Downlink Shared Channel, High Speed ​​Downlink Shared Channel) data on a spe...

Abstract

The invention discloses a terminal power saving method and device. The terminal power saving method comprises the following steps: a terminal receives the HS-SCCH (high-speed shared control channel) sent by a base station and does not start or restart an HS-SCCH inactive timer after judging that a transmission block size domain carried by the HS-SCCH is 0. The terminal power saving device is arranged in the terminal and comprises a receiving module and a power saving module. Due to the adoption of the terminal power saving method and device, the terminal can be still kept in the DRX (discontinuous reception) state or made to enter the DRX state as soon as possible after receiving the air conditioning degree of the HS-SCCH sent by the base station, thus the purpose of saving power is achieved, the problem that the terminal exits the DRX state or delays to enter the DRX state after receiving the air conditioning degree to leads to the power consumption of the terminal is solved, the standby time of the terminal and the service life of the batteries of the terminal can not be affected.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a terminal power saving method and device. Background technique [0002] In HSPA+, in order to achieve the purpose of terminal power saving, control channels (such as HS-SCCH (High Speed ​​Shared Control Channel) and E-AGCH (E-DCH Absolute Grant Channel)) in the state of CELL DCH (Cell Dedicated Channel) are introduced. Discontinuous reception (discontinuous reception, DRX) function, when the terminal does not send uplink data for a period of time or does not receive the scheduling of the base station, it can enter the DRX state, and the terminal in the DRX state only needs to receive when the DRX cycle arrives. Yes, when the terminal has data to send or receives scheduling from the base station side, the terminal needs to exit the DRX state for continuous reception or transmission. [0003] In HSPA+, it is allowed to remove the accompanying DPCH (Dedicated Physical C...
