Problems solved by technology

It can be seen from the above process that if the DRX Short Cycle Timer does not start from the starting point of the on-duration of the DRX cycle, when the DRX Short Cycle Timer expires, there is no guarantee that the time when it arrives is exactly the on-duration of the Long DRX cycle The starting point, and if the starting position of the Long DRX cycle is not sure, it may lead to inconsistencies between the behaviors of the base station (eNode B) and the UE, resulting in the UE being unable to receive data correctly

Embodiment 1

[0044] Figure 4 A schematic diagram of UE entering long DRX in Embodiment 1 is shown. Specifically, starting Figure 4 Shown:

[0045] Time T1: The UE receives the PDCCH indicating the transmission of downlink data or uplink data, and starts the DRX inactivity timer timer;

[0046] Time T2: DRX inactivity timer expires;

[0047] T3 moment: the starting time of DRX Short Cycle Timer (starting at the starting point of the next short DRX cycle when the DRX inactivity timer timer expires);

[0048] Time T4: When the DRX Short Cycle Timer expires, this time is the starting point of the long DRX cycle in which the UE enables long DRX.

Embodiment 2

[0050] Figure 5 A schematic diagram of UE entering long DRX in Embodiment 2 is shown. Specifically, such as Figure 5 Shown:

[0051] Time T1: The UE receives the PDCCH indicating the transmission of downlink data or uplink data, and starts the DRX inactivity timer timer;

[0052] Time T2: When the DRX inactivity timer expires, it happens that the current shortDRX cycle ends;

[0053] T2 moment: start DRX Short Cycle Timer at the same time;

[0054] Time T4: When the DRX Short Cycle Timer expires, this time is the starting point of the long DRX cycle in which the UE enables long DRX.

Abstract

The invention discloses a starting point setting method for discontinuously-receiving long cycle period, and a control method for user equipment to start the long discontinuous reception, and a device thereof. In the control method, when a discontinuous reception inactive timer of the user equipment is at the time, a timer for a discontinuously-receiving short cycle period is started at the preset starting point of the discontinuously-receiving cycle period, wherein the duration of the timer for the discontinuously-receiving short cycle period is integral multiple that of the discontinuously-receiving short cycle period; when the discontinuously-receiving short cycle period timer is at the time, the user equipment starts the discontinuously-receiving long cycle period, and adopts the stopping time of the discontinuously-receiving short cycle period timer as the starting point of the discontinuously-receiving long cycle period. By the invention, when the DRX Short Timer is at the time, the starting point of the Long DRX Cycle just begins.

Description

technical field [0001] The present invention relates to a Discontinuous Reception (DRX) mechanism in the field of communication, in particular, to a control method and device for Discontinuous Reception, and a method for setting a starting point of a long cycle of Discontinuous Reception. Background technique [0002] With the further evolution of wireless communication technology, in order to simplify the maintenance status of a user equipment (UseEquipment, referred to as UE) and network side equipment for a user, the radio resource control (Radio Resource Control, referred to as RRC) connection mode is reduced. Various states, that is, only RRC connected mode and idle mode exist. [0003] In the RRC connection mode, the UE can perform data transmission and reception and various measurements, and the UE in the RRC connection mode has to monitor the downlink control channel all the time. In this way, the power consumption of the UE is relatively large. Therefore, 3GPP (3rd ...
