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 the various states under Radio Resource control (Radio Resource Control the abbreviates RRC as) connection mode; Also promptly, only there are RRC connection mode and idle pulley.
Under the RRC connection mode, UE can carry out the transmitting-receiving and the various measurement of data, and the UE that is in the RRC connection mode will monitor descending control channel always; Like this, the power consumption of UE is bigger, therefore; 3GPP (3rd Generation partnership project, third generation mobile gpp) standard agreement has been introduced discontinuous reception (Discontinuous Reception abbreviates DRX as) technology: when UE is in the RRC connection mode; When it does not transmit and receive data; When does not perhaps dispatch it the base station, can use discontinuous reception technique, thereby reach the purpose of saving power.
When UE launched discontinuous reception, as shown in Figure 1, periodically revived in the pre-configured moment of network in the terminal; And on-duration timer (timer of reviving) is set, and wherein, on-duration is the time interval of reviving; After the on-duration, the terminal gets into sleep.The temporal summation of reviving and sleeping is exactly a DRX cycle (a discontinuous reception cycle period), and the moment that on-duration begins is called the starting point of DRX cycle.
Present discontinuous reception technique has adopted the cycle period of short discontinuous reception and two kinds of mechanism of cycle period of long discontinuous reception; Promptly; When UE not have to receive or sends data, then launch the discontinuous reception (long_DRX) that the cycle period of the discontinuous reception of length is controlled in a relatively long time; When UE does not receive or sends data, then launch the discontinuous reception (short_DRX) that the cycle period of short discontinuous reception is controlled 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 new data of sending, 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 new data of sending, can restart DRX inactivitytimer so.At DRX inactivity timer run duration, the terminal is in wake states always.When DRX inactivity timer arrives constantly; If disposed the short cycle period of discontinuous reception; Then the discontinuous reception that the short cycle period of discontinuous reception is controlled is launched at the terminal, and starts the short cycle period timer (DRX Short Cycle Timer) of DRX; When DRX ShortCycle Timer arrives constantly, then launch the discontinuous reception that the long cycle period of discontinuous reception is controlled.
From the DRX cycle of present definition, a DRX cycle begins from duration.Can find out from said process; If not being the starting point from the on duration of DRX cycel, DRX Short Cycle Timer do not begin; Then when DRX Short Cycle Timer to constantly, just can't guarantee that its moment point then just in time is the starting point of the onduration of Long DRX cycel, and if the original position of uncertain Long DRX cycle; It is inconsistent just may to arrive the behavior meeting appearance that causes base station (eNode B) and UE, thereby causes UE can't correctly receive data.Therefore, need a kind of technical scheme that addresses the above problem.
