Problems solved by technology

However, this piggybacking method has the following disadvantages, that is, because the data packet transmission adopts the HARQ mechanism, there is a hidden danger of large transmission delay, and the real-time control of the DRX state of the user equipment cannot be completed.

Embodiment Construction

[0043] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings, and unnecessary details and functions for the present invention will be omitted during the description to prevent confusion in the understanding of the present invention.

[0044] figure 1 An embodiment of the DRX control device at the network side base station (for example, eNB) according to the present invention is shown. like figure 1 As shown, the DRX control device at the base station includes a service queue module 11 , a scheduling module 12 , a discontinuous reception (DRX) prediction module 13 , and a transmitter module 14 .

[0045] In order to adaptively and dynamically modulate the DRX of the user equipment, the DRX control device at the base station is configured with a DRX prediction module 12 . When the downlink packet to be sent to the user equipment arrives at the network side, the data packet first enters the service module queue 11 of ...

Abstract

The present invention discloses a method for dynamically controlling the non-continuous receiving of user facility with a self-adapting mode. The invention comprises the following steps: allocating resource for the schedulable user facility at the network side in scheduling period, and confirming whether the data to be transmitted to each schedulable user facility exists after present scheduling period; indicating a token indicating whether the data to be transmitted to the user facility exists for the user facility according to the confirmation result, and transmitting the set token and scheduling information together to the user facility; and controlling the receiver to enter into a dormancy stage or continue in the activation period by the user facility according to the received token, wherein when the token shows that the data to be transmitted to the user facility exist at the network side, the user facility controls the receiver in the activation period. When the token shows that data to be transmitted to the user facility do not exist, the user facility controls the receiver to enter the dormancy stage.

Description

technical field [0001] The present invention relates to a method and device for dynamically controlling discontinuous reception, in particular, relates to predicting whether to send data to user equipment (UE, User Equipment) in the next scheduling period, and adding a flag bit in the downlink scheduling information to notify the prediction result A user equipment, and further a method and a device for controlling the switch state of a receiver of the user equipment. Background technique [0002] With the development of communication in the direction of mobility and broadband, the energy saving of mobile terminals has been widely concerned. Many communication standardization organizations have added energy-saving considerations when formulating relevant standards. In particular, the access network of the future mobile communication system will be based on IP technology for data transmission, and the burst characteristics of IP data packets and the sharing characteristics of...
