Problems solved by technology

In this case, if according to the existing practice, a terminal is configured with a set of DRX processes for power saving control, for integrated services, its periodicity is not clear, and the DRX parameters are difficult to determine, resulting in relatively random data transmission, which is very Difficult to match the sending cycle of integrated services, there may be cases where no data is sent during the On Duration cycle, resulting in unnecessary wake-ups and poor power-saving performance

Embodiment 1

[0064] figure 2 It is a schematic flow chart of Embodiment 1 of the method for realizing discontinuous reception in the present invention, as figure 2 As shown, the method includes the following steps:

[0065] Step 201, the network side periodically configures a set of DRX parameters for the terminal according to the data transmission of service 1, and sends the configured DRX parameters to the terminal through signaling;

[0066] Specifically, service 1 is running in the terminal, and the data transmission of this service has a certain periodicity, so it is suitable for performing DRX control. Then, the network side configures a set of DRX parameters for the terminal according to the data transmission period of service 1. The DRX parameters include On Duration Timer, DRX Inactivity Timer, DRX Retransmission Timer, long DRX offset (long DRX Cycle StartOffset), optionally, can also include short DRX cycle (short DRX Cycle) and short DRX cycle times (DRX short Cycle Timer); ...

Embodiment 2

[0077] Figure 4 It is a schematic flow chart of Embodiment 2 of the method for realizing discontinuous reception in the present invention, such as image 3 As shown, the method includes the following steps:

[0078] Step 401, the network side configures two sets of DRX parameters for the terminal according to the different data transmission periods of the integrated service sub-service 1 and sub-service 2;

[0079] Specifically, an integrated service is running in the terminal. The integrated service is composed of two single services, namely, sub-service 1 and sub-service 2. The data transmission of the sub-service 1 and sub-service 2 has a certain periodicity, which is suitable for performing DRX control. However, the data transmission periods of the two services are different;

[0080] The network side configures the first set of DRX parameters for the terminal according to the data transmission period of sub-service 1, including On Duration Timer, DRX Inactivity Timer, ...

Abstract

The invention discloses a discontinuous reception (DRX) method. The DRX method comprises the following steps that: a terminal receives at least one set of DRX parameters which is configured and sent by a network side; and the terminal starts a corresponding number of DRX processes according to at least one set of DRX parameters. The invention also provides a DRX system. According to the technical scheme provided by the invention, the behaviors of the terminal and the characteristics of services can be optimally matched, and the aim of saving power is fulfilled.

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...
