Embodiment Construction

[0038] In practical applications, if the Paging subframe monitored by the UE is in the Sleep period controlled by DRX, the network side can transmit downlink data or downlink signaling in the Paging subframe for the UE, regardless of whether the UE is in the Sleep period of DRX ; The UE can read the downlink data and signaling for the UE in the Paging subframe.

[0039] Specifically, according to the characteristics of the service run by the UE, the network side decides to configure DRX configuration parameters for the UE. The service characteristics include data transmission periodicity, data packet size, delay requirements, etc.; the DRX configuration parameters include DRX cycle, etc.

[0040] Moreover, the network side can judge whether it is suitable to configure the DRX mechanism according to the service characteristics, as well as specific DRX configuration parameters, such as long DRX cycle (Long DRX Cycle), short DRX cycle (short DRX cycle), activation timer, retransm...

Abstract

The invention discloses a method and a system for implementing DRX. UE (User Equipment) can receive downlink data and / or downlink signaling transmitted in a paging sub-frame by a network side, wherein the downlink data and / or downlink signaling are / is sent when the Paging sub-frame, monitored by the UE, is located in a sleep period of DRX control. According to the invention, the technology for implementing the DRX allows the network side to transmit the downlink data and / or signaling to the UE through the paging sub-frame during the DRX sleep period of the UE, so that the buffered downlink data and / or signaling can be transferred to the UE in time by taking the opportunity that the UE monitors that the paging sub-frame is awake, and the data can be sent to the UE in time without waiting for a next On Duration period; and thus, the UE is more power-saving, the user experience can be improved, and a data amount buffered at the network side can be reduced.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and system for realizing DRX (Discontinuous Reception, discontinuous reception). Background technique [0002] The function of the DRX mechanism is simply that the user equipment (UE) stops monitoring the physical downlink control channel (PDCCH) for a period of time to save power. [0003] There are two types of DRX: one of DRX is idle (IDLE) DRX. At this time, there is no radio resource control (RRC) connection and user-specific resources. If the UE wants to monitor the user data channel, it must first enter the connected state from the IDLE state. [0004] Another type of DRX is non-idle (ACTIVE) DRX, that is, DRX in which the UE is in an RRC-CONNECTED state. ACTIVE DRX can optimize system resource allocation, and more importantly, it can save UE power consumption. [0005] In fact, the UE in the connected state still needs to monitor the paging (Paging) to know ...
