Abstract
The invention discloses a starting point determining method for a discontinuously-receiving long cycle period, a control method for discontinuous reception, and a device thereof. In the control method, when a timer for the discontinuously-receiving short cycle period is at the time, the preset starting point of a discontinuously-receiving cycle period is adopted as the starting point of the discontinuously-receiving long cycle period; wherein when an awake timer runs at the current time, the preset discontinuously-receiving cycle period is the discontinuously-receiving cycle period after the discontinuously-receiving cycle period when the awake timer runs; when no awake timer runs at the current time, the preset discontinuously-receiving cycle period is the discontinuously-receiving cycle period after the discontinuously-receiving cycle period corresponding to the awake timer which runs at the latest time. By the invention, the starting point of the discontinuously-receiving long cycle period is determined when user equipment enters long discontinuous reception from short discontinuous reception, so that a base station and the user equipment can use the discontinuously-receiving long cycle period by adopting an identical rule.
Description
Technical field
The present invention relates to discontinuous reception (DiscontinuousReception the abbreviates DRX as) mechanism in the communications field, particularly, relate to the control method and the device of discontinuous reception, and the starting point of the long cycle period of discontinuous reception is determined method.
Background technology
Further evolution along with wireless communication technology, in order to simplify a subscriber equipment (UseEquipment, abbreviate UE as) and network equipment to a user's maintenance state, reduced Radio Resource control (Radio Resource Control, abbreviate RRC as) various states under the connection mode, also promptly, only there are RRC connection status and RRC idle condition.
Under the RRC connection status, UE can carry out the transmitting-receiving and the various measurement of data, and the UE that is in the RRC connection status will monitor descending control channel always, like this, the power consumption of UE is bigger, therefore, 3GPP (3rd Generation partnership project, third generation mobile partner plan) standard agreement has been introduced discontinuous reception (Discontinuous Reception, abbreviate DRX as) technology: when UE is in the RRC connection status, when it does not transmit and receive data, when does not perhaps dispatch it the base station, can start discontinuous reception technique, thereby reach the purpose of saving power.
When UE was in discontinuous reception, as shown in Figure 1, terminal was periodically revived in the pre-configured moment of network, and on-duration timer (timer of reviving) is set, and wherein, on-duration is the time interval of reviving, after the on-duration, terminal enters sleep.The temporal summation of reviving and sleeping is exactly a DRX cycle (a discontinuous receiving cycle), and the moment that on-duration begins is called the starting point of DRX cycle.
Present discontinuous reception technique has adopted the short cycle period of discontinuous reception and two kinds of mechanism of the long cycle period of discontinuous reception,, when UE does not have to receive or sends data, then adopts the long cycle period of discontinuous reception in a relatively long time that is; When UE does not receive or sends data, then adopt the short cycle period of discontinuous reception in a relatively short time.Wherein, the length of the long cycle period of discontinuous reception is the integral multiple of the length of the short cycle period of discontinuous reception.The configuration of the short cycle period of discontinuous reception is optional.If UE has disposed two cycle periods simultaneously, then there is the problem how between two cycle periods, to change.
In the time of in UE is in the time period that on duration controlled, UE need monitor Physical Downlink Control Channel (Physical downlink control channel, abbreviate PDCCH as), if what listen to PDCCH and this PDCCH indication is the new data that send, then start the non-active timer (DRX inactivity timer) of discontinuous reception, at DRXinactivity timer run duration, UE need monitor PDCCH.If what listen to this PDCCH indication is the new data that send, can restart DRX inactivitytimer so.At DRX inactivity timer run duration, terminal is in wake states always.When DRX inactivity timer arrives constantly, if disposed short discontinuous reception cycle period, then terminal is enabled the discontinuous reception that the short cycle period of discontinuous reception is controlled, and starts the short cycle period timer (DRX Short Cycle Timer) of DRX; When DRXShort Cycle Timer arrives constantly, then enable the discontinuous reception that the long cycle period of discontinuous reception is controlled.
From the DRX cycle of present definition, a DRX cycle is from duration.If when DRX Short Cycle Timer timer arrives constantly, it is not the initial moment of onduration, after enabling Long DRX so, for UE, the starting point of its LongDRX cycle, promptly how the time point that begins of on-duration is determined, do not provide at present concrete solution as yet, if and the starting point of the ong DRX cycle of uncertain UE, inconsistent situation will appear in the behavior of base station (eNode B) and UE, thereby causes UE can't correctly receive data.
Summary of the invention
Consider exist in the correlation technique for how at DRX Short Cycle Timer timer to constantly, this problem of starting point of determining DRX Long cycle is an open question and propose the present invention still, for this reason, the present invention aims to provide a kind of control method and device of growing discontinuous reception, and the starting point of the long cycle period of discontinuous reception determines that method is in order to address the above problem.
