Problems solved by technology

[0021] In the case of more complex business characteristics, in order to save power, it is necessary to introduce a larger DRX Cycle cycle, but if the long DRX Cycle cycle is set to a large value (such as tens of seconds), and the existing two Level cycle control, there may be no data to be transmitted in several short DRX Cycle cycles, the terminal will enter a long DRX Cycle cycle, and then the terminal will be in a long-term sleep state, so when in this sleep state, if data arrives, the data will be cached , wait until the On Duration period to transmit, which will inevitably bring a large delay

Embodiment 1

[0063] figure 2 It is a schematic diagram of the DRX Cycle period of Embodiment 1 of the method for realizing discontinuous reception in the present invention, as shown in figure 2 As shown, in this embodiment, there are three DRX Cycle cycles, and the terminal enables the DRX Cycle cycle according to preset rules. This embodiment includes the following steps:

[0064] Step 1. The terminal is running a data service. The data transmission cycle of this service is relatively complicated. Therefore, the network side configures DRX parameters for the terminal, including three DRX Cycle cycles, namely short DRX Cycle cycle, long DRX Cycle cycle, and Superlong DRX Cycle cycle. cycle, where the value of DRX Cycle can be infinite; at the same time, the network side also configures the usage strategy of three DRX Cycle cycles, that is, M / N, where M and N are both integer values ​​greater than or equal to 0. When M short When there is no data transmission / reception within the DRX Cyc...

Abstract

The invention discloses a discontinuous reception (DRX) method. The DRX method comprises the following steps that: a terminal receives DRX parameters which are configured and sent by a network side, wherein the DRX parameters carry a plurality of DRX cycles; and the terminal starts a DRX process according to the DRX parameters, and starts the corresponding DRX cycles during operation of the DRX process. The invention also provides a DRX system. According to the technical scheme provided by the invention, the terminal can well meet a data sending requirement during operation of a DRX technology.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a discontinuous reception method and system. Background technique [0002] Discontinuous reception (DRX, Discontinuous Reception) means that a terminal stops monitoring a Physical Downlink Control Channel (PDCCH, Physical Downlink Control Channel) for a period of time. There are two types of DRX: one is idle (IDLE) DRX, which is discontinuous reception when the terminal is in the IDLE state; when it is in the IDLE state, there is no radio resource control protocol (RRC, Radio Resource Control) connection and the user's proprietary Therefore, IDLE DRX is mainly used to monitor the call channel and broadcast channel. As long as the fixed period is defined, the purpose of discontinuous reception can be achieved; however, if the terminal monitors the user data channel, it must first enter the connection state from the IDLE state. The other is to activate (Active) DRX, tha...
