Problems solved by technology

[0005] However, in the prior art, the DRX configuration of each carrier corresponding to the UE is common, and the network side notifies the UE to enter the sleep state only when all the carriers of the UE will not be scheduled for a period of time, and the UE can only perform DRX configuration for all carriers. DRX control, that is to say, every time the UE performs DRX control, it must control all carriers to enter the sleep state
Normally, the network side may only schedule some carriers of the UE. If the solution of the prior art is used, the network side will not notify the UE to perform DRX control at this time, so that the flexibility of DRX control is poor, and it cannot be fully reduced. The power consumption of the UE, the purpose of saving the power of the UE

Embodiment 1

[0147] Firstly, the DRX control process on the base station side is introduced.

[0148] Such as figure 1 As shown, it is a flow chart of the discontinuous reception control method on the base station side proposed in Embodiment 1 of the present invention, and its specific processing flow is as follows, including:

[0149] Step 11, the base station determines the carrier that needs to be controlled by DRX among the carriers corresponding to the UE.

[0150] Step 12: Send the determined carrier identifier of the carrier to the UE, instructing the UE to perform DRX control on the carrier corresponding to the received carrier identifier.

[0151] In Embodiment 1 of the present invention, performing DRX control on the carrier may be to control the carrier to enter a sleep state, or to control the carrier to wake up from the sleep state. The DRX control schemes in these two cases are respectively introduced below.

[0152] Case 1. The control carrier enters the sleep state.

Embodiment 2

[0186] The following describes the DRX control process on the UE side.

[0187] Such as Figure 4 As shown, it is a flow chart of the discontinuous reception control method proposed in Embodiment 2 of the present invention, and its specific processing flow is as follows, including:

[0188] In step 41, the UE receives the carrier identifier of the carrier that needs to be controlled by DRX sent by the base station.

[0189] Step 42, the UE performs DRX control on the carrier corresponding to the received carrier identifier.

[0190] In Embodiment 2 of the present invention, performing DRX control on the carrier may be to control the carrier to enter the sleep state, or to control the carrier to wake up from the sleep state. The DRX control schemes in these two cases are respectively introduced below.

[0191] Case 1. The control carrier enters the sleep state.

[0192] The base station performs DRX control according to the method described in Case 1 in Embodiment 1 of the ...

Embodiment 3

[0217] Corresponding to the discontinuous reception control method proposed in Embodiment 1 of the present invention, Embodiment 3 of the present invention proposes a base station whose structure is as follows Figure 5 shown, including:

[0218] The carrier determining unit 51 is configured to determine, among the carriers corresponding to the UE, the carrier that needs to be controlled by DRX;

[0219] The carrier identifier sending unit 52 is configured to send the carrier identifier of the carrier determined by the carrier determining unit 51 to the UE, and instruct the UE to perform DRX control on the carrier corresponding to the received carrier identifier.

[0220] Preferably, the carrier determining unit 51 specifically includes:

[0221] The first carrier selection subunit is used to select the carrier that needs to enter the sleep state among the carriers corresponding to the UE;

[0222] The first carrier confirmation subunit is configured to confirm the carrier s...

Abstract

The invention discloses a discontinuous reception (DRX) control method and equipment. The method comprises the following steps that: a base station determines carriers needing to be subjected to DRX control in each carrier corresponding to UE (User Equipment); and the carrier identifiers of the determined carriers are transmitted to the UE, the UE receives the carrier identifiers of the carriers needing to be subjected to DRX control transmitted by the base station, and DRX control is performed on the carriers corresponding to the received carrier identifiers. Through adoption of the technical scheme, the flexibility of DRX control can be enhanced; the energy consumption of the UE is lowered; and the electric quantity of the UE is saved.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a discontinuous reception control method and equipment. Background technique [0002] In order to make full use of the operator's spectrum resources and provide users with higher peak rates, the technology of configuring multiple carriers for a user equipment (UE) has emerged as the times require, such as multi-carrier aggregation technology, frequency division duplex (Frequency Division Duplexing (FDD) / Time Division Duplexing (Time Division Duplexing, TDD) fusion technology is a multi-carrier technology currently being discussed by the International Organization for Standardization. [0003] When the UE occupies multiple carriers, the Discontinuous Reception (DRX) function allows the UE to turn off the receiver under certain conditions without always being in the state of listening to the channels corresponding to each carrier. Listen to the physical downlink con...
