Background technology
Along with the development of communication technology, (English: Long Term Evolution is called for short: LTE) be Long Term Evolution System can provide the user more abundant communication service, but when user enjoys these communication services, terminal but can be made to set Standby power consumption is particularly acute.At present, in order on the premise of ensureing service quality, reduce the merit of terminal unit as far as possible Consumption, proposes the discontinuous reception under connected state (English: Connected State Discontinuous in LTE system Reception, is called for short: CDRX) mechanism, and under this mechanism, terminal unit carries out the transmitting-receiving of data the most at a fixed time, remaining Time is in the resting state that electric quantity consumption is relatively low.Concrete, as it is shown in figure 1, when be in discontinuous reception (English: Discontinuous Reception, is called for short: during activation phase in DRX) cycle, terminal unit can detect whether data, if Have data, then carry out the transmitting-receiving of data, when being in the inactive phase of DRX cycle, terminal unit the most in a dormant state, until It is waken up when the opportunity of waking up up arrives so that be again in the activation phase when the starting point of the phase of activation arrives.
It addition, in LTE system, when terminal unit has upstream data to need to send, first obtain up awarding from network side Power, after the uplink authorization obtaining network side, just can carry out the transmission of upstream data.Terminal unit can be by network Side sends dispatch request, and (English: Scheduling Request is called for short: SR) to obtain the uplink authorization of network side, and SR must Must be transmitted opportunity in specific transmission.
To sum up, if when there being upstream data to need to send, terminal unit, just at the inactive phase, is i.e. in dormancy shape State, then the transmission opportunity of SR and the opportunity that wakes up up of terminal unit may be misaligned, and terminal unit so will be caused first to wait The opportunity of waking up up is waken up, and waits that the transmission of SR just can carry out the transmission of SR opportunity the most again, and then acquisition the up of network side is awarded Power, to be sent by upstream data, owing to should wait the opportunity of waking up up under this mode, also waits for the transmission opportunity of SR, Therefore the time delay sending upstream data can be made bigger.In order to reduce the time delay sending upstream data, prior art provides one Scheme, if particularly as follows: when terminal unit is in the inactive phase, having upstream data to need to send, forcing the most immediately to wake up terminal up Equipment, in order to terminal unit enters the activation phase, waits that the transmission of SR carries out the transmission of SR opportunity the most again, and then obtains network side Uplink authorization, so that upstream data is sent.
Although the scheme of prior art reduces the transmission delay of upstream data, but, it is forced to wake up up at terminal unit After, the transmission still needing to wait for SR just can carry out the transmission of SR opportunity, and after being forced to wake up up to SR transmission opportunity this In the section time, terminal unit can not perform any operation, always in power consumption, say, that although in the scheme of prior art Reducing the transmission delay of upstream data, the power consumption that but can cause terminal unit is bigger.Therefore, the province of terminal unit how is taken into account Electrical efficiency and the delay requirement that upstream data is sent, it has also become the important topic of this area research.

The flow chart of a kind of data transmission method that Fig. 3 provides for the embodiment of the present invention, as it is shown on figure 3, the method is permissible Including:
201, when there being upstream data to send, terminal unit determines the inactive phase self being in the CDRX cycle.
Wherein, upstream data is terminal unit having detected when communication service needs to be initiated to be that this communication service generates Data.When terminal unit has detected that communication service needs to be initiated, terminal unit can generate the upper of this communication service Row data, now indicate that upstream data needs to send, and terminal unit can first judge self whether to be in swashing of CDRX cycle Current, within this activation phase, the radio receiving-transmitting unit of terminal unit can transceiving data, however, it is determined that self be in the CDRX cycle The activation phase, then can wait the transmission opportunity needing moment of being initiated nearest SR away from communication service, first send out to the network equipment Send SR, and after receiving the uplink authorization that the network equipment is sent in response to this SR, send upstream data；If it is determined that be certainly in In the inactive phase in CDRX cycle, within this inactive phase, the radio receiving-transmitting unit of terminal unit can not transceiving data, i.e. table Bright terminal unit in a dormant state, then can perform following steps 202.The resting state mentioned in the present embodiment shows terminal Equipment is in the inactive phase in CDRX cycle, and now the radio receiving-transmitting unit of terminal unit can not transceiving data.
In embodiments of the present invention, terminal unit can be terminal unit detecting that communication service needs to be initiated Hardware or bottom software detect that upper layer software (applications) needs to initiate data communication service.
202, in terminal unit judges the activation phase whether first transmission of SR is included in the CDRX cycle opportunity.
Wherein, after the activation phase is in the inactive phase, the first transmission is to need, away from communication service, moment of being initiated opportunity The transmission opportunity of nearest SR.When terminal unit determines the inactive phase self being in the CDRX cycle, in order to avoid calling out too early The radio receiving-transmitting unit of awake terminal unit causes terminal unit power consumption serious, and terminal unit can first judge away from communication service needs The transmission opportunity of the SR that moment of being initiated is nearest, in the activation phase whether the i.e. first transmission is included in the CDRX cycle opportunity.By Know the CDRX cycle in terminal unit, therefore can judge that a moment is in the activation in CDRX cycle according to the CDRX cycle In phase or in the inactive phase.
If 203 first transmissions are included in the inactive phase opportunity, then terminal unit judges what communication service needs were initiated Moment and first sends whether the difference on opportunity meets default wake-up condition.
Wherein, at the beginning of being needed execution to power on due to the radio receiving-transmitting unit of terminal unit by non-wake-up states entrance wake-up states Beginningization, in-situ FTIR spectroelectrochemitry or clock synchronization etc. operate, in order to terminal unit enters from resting state can the activation shape of transceiving data State, if therefore terminal unit judges to obtain to need the transmission of moment of being initiated nearest SR to be included in opportunity away from communication service Time in the inactive phase in CDRX cycle, terminal unit also needs further to judge that communication service needs the moment and first being initiated Whether the difference on transmission opportunity meets is preset wake-up condition, i.e. judges to be needed the moment being initiated to send to first by communication service Whether can perform opportunity the power-up initializing of radio receiving-transmitting unit, in-situ FTIR spectroelectrochemitry (i.e. restoring scene data or content) or time Clock synchronizations etc. operate.Wherein, radio receiving-transmitting unit include radio frequency (English: Radio Frequency, be called for short: RF) transceiver and Baseband processor at least some of.When terminal unit in a dormant state, RF transceiver may be at resting state, Yi Jiji Provided with processor partly or entirely may be at resting state.After the radio receiving-transmitting unit of terminal unit is activated or wakes up up, RF transceiver and baseband processor all will be in wake-up states, i.e. be powered on initializing from resting state, realize in-situ FTIR spectroelectrochemitry or Clock synchronizes, for setting up wireless connections with the network equipment 12.
If 204 differences meet presets wake-up condition, then terminal unit wakes up wake on wireless transceiver on opportunity up first, And send SR opportunity by radio receiving-transmitting unit in the first transmission.
Wherein, described first wake up up be positioned at opportunity the inactive phase, be no earlier than moment that communication service needs to be initiated, And send opportunity early than first.If the moment and first that judging to obtain communication service needs to be initiated sends the difference on opportunity and meets Preset wake-up condition, then terminal unit just can wake up wake on wireless transceiver on opportunity up first, and passes through wireless receiving and dispatching Letter machine sends SR opportunity in this first transmission, so receive uplink authorization that the network equipment sent in response to this SR it After, in time upstream data is transmitted.
The data transmission method that the embodiment of the present invention provides, if there being upstream data to need to send, and terminal unit determines self Just at the inactive phase in CDRX cycle, then terminal unit can determine that the first transmission is included in the non-of CDRX cycle opportunity Time in the activation phase, it is judged that communication service needs the moment being initiated and first to send the most satisfied default wake-up bars of difference on opportunity Part, and determine when difference meets wake-up condition, wakes up up first and wakes up the radio receiving-transmitting unit of terminal unit opportunity up, and then permissible SR is sent opportunity in the first transmission by radio receiving-transmitting unit.So, both without waiting for waking up opportunity up, it it is not line number on having According to forcing to wake up up the radio receiving-transmitting unit of terminal unit time to be sent immediately, but need the moment being initiated according to communication service Transmission opportunity with SR, it is ensured that the radio receiving-transmitting unit of terminal unit was called out on the nearest opportunity that wakes up up meeting wake-up condition Wake up, so that the transmission at SR sends SR opportunity, reached take into account the power saving efficiency of terminal unit simultaneously and upstream data is sent out The purpose of the delay requirement sent.
The flow chart of the another kind of data transmission method that Fig. 4 provides for the embodiment of the present invention, as shown in Figure 4, the method can To include:
301, when there being upstream data to send, terminal unit judges self whether to be in the inactive phase in CDRX cycle.
Wherein, upstream data is terminal unit having detected when communication service needs to be initiated to be that this communication service generates Data.When terminal unit has detected that communication service needs to be initiated, it is up that terminal unit can generate this communication service Data, now indicate that upstream data needs to send, and terminal unit can first judge whether self is in the activation in CDRX cycle Phase, within this activation phase the radio receiving-transmitting unit of terminal unit can transceiving data, if terminal unit determines that self is in CDRX The inactive phase in cycle, within this inactive phase the radio receiving-transmitting unit of terminal unit can not transceiving data, then perform below Step 302-step 308, if terminal unit determines the activation phase self being in the CDRX cycle, then terminal unit can be away from communication The transmission of the SR that moment that service needed is initiated is nearest sends SR to the network equipment opportunity, and is receiving network equipment response After the uplink authorization that this SR is sent, send upstream data.
Wherein, the transmission of SR refers to carry out the transmission of SR in specific system-frame and time slot opportunity, and concrete can basis FormulaDetermine transmission opportunity, wherein, nfRepresent system-frame Number, nsRepresent the timeslot number in 1 system-frame, NOFFSET,SRThe expression cycle, SRPERIODICITYRepresenting side-play amount, Mod represents delivery Computing, NOFFSET,SRAnd SRPERIODICITYSR configuration index (English: the configuration that can issue according to the network equipment Index) look-up table 1 obtains, nfAnd nsIt is provided commonly for determining the transmission opportunity of SR.And terminal unit can according to obtain multiple Transmission opportunity and communication service need the moment being initiated to determine away from communication service needs moment of being initiated nearest SR's Transmission opportunity.
