Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of resource regulating method and device.
Background technology
In existing Long Term Evolution (LongTermEvolution, LTE) system, from version 8 (Release8, R8) start for the speech business (VoiceoverLTE, VoLTE) based on LTE this regular,Packet is less, the relatively-stationary service design of data package size semi-persistent scheduling (Semi-PersistentScheduling, SPS) dispatching algorithm, its principle is for using the reserved a series of resource of control signal,To reduce the expense of control signal, reach the object that increases VoLTE user capacity.
The configuration of SPS dispatching algorithm by layer three radio resource control (RadioResourceControl,RRC) the control activation signaling of configuration signal and layer one physical layer completes jointly. Layer three RRC configuration signalResponsible configuration SPS cycle, buffer memory process (HARQprocess) number of use, binary cycle SPS openOpen etc., its configuration signal form is based on standard agreement 3GPPTS36.331.
Layer three RRC signaling are being carried out after the configuration of SPS scheduling, activate signaling by the control of layer one physical layerCarry out the activation of SPS scheduling. This signaling is made up of special form, is responsible for determining the initial of SPS resourcePosition, transformat etc. The form of this signaling is based on standard agreement 3GPPTS36.213.
But, in the standard agreement of existing LTE system, only have above-mentioned about configuration SPS signaling formatRegulation, the not trigger condition of specified configuration SPS, but SPS scheduling has in LTE systemFollowing feature and problem:
One, be exclusively used in VoLTE business: VoLTE business has that data package size is fixed, the cycle is fixed,And the feature that data package size is less, therefore fixed resource position and the size of SPS scheduling are well suited for VoLTEBusiness; And SPS scheduling can effectively reduce the expense of control signal to increase VoLTE capacity. But,Other data services except VoLTE business are also not suitable for using SPS scheduling;
Two, there is active period and quiet period in VoLTE business, and in active period, VoLTE packet is with 20Millisecond (ms) interval arrives, and is therefore suitable for SPS scheduling; In quiet period, VoLTE packet is with 160msArrive, now because packet interval is larger, be therefore no longer suitable for SPS scheduling;
Three, SPS scheduling is owing to being subject to impact, maximum modulation and the coding of physical layer control activation signaling formatStrategy (ModulationandCodingScheme, MCS) can only use 15. Therefore, at channelWhen condition is particularly preferred, for example: when the signal to noise ratio of channel is greater than 20 decibels (dB), use SPS to adjustDegree can increase physical down link sharing channel (PhysicalDownlinkSharedChannel, PDSCH)Physical Resource Block (PhysicalResourceBlock, the PRB) number using, therefore can reduce frequency spectrum and makeBy efficiency, be not suitable at this moment using SPS scheduling.
In sum, in prior art, do not have in conjunction with semi-persistent scheduling the feature in LTE system and problemThe trigger condition of specified configuration semi-persistent scheduling, thus cause semi-persistent scheduling to have inapplicable situation.
Summary of the invention

Detailed description of the invention
Below in conjunction with accompanying drawing, the resource regulating method that the embodiment of the present invention is provided and the specific embodiment party of deviceFormula is described in detail.
A kind of resource regulating method that the embodiment of the present invention provides, as shown in Figure 1, comprising:
Step 102, in the time that needs carry out scheduling of resource, judges whether to meet the trigger condition of semi-persistent scheduling;
Step 104, in the time meeting trigger condition, adopts Semi-static scheduling method to carry out resource to current businessScheduling.
In the method that the embodiment of the present invention provides, according to the trigger condition of pre-configured semi-persistent scheduling, fromAdapt to ground and adopt Semi-static scheduling method to carry out scheduling of resource to meeting the business of trigger condition, thereby avoid depositingIn the inapplicable situation of semi-persistent scheduling, semi-persistent scheduling can be entered more neatly in conjunction with concrete conditionRow configuration is used, thereby brings corresponding beneficial effect, for example: and reduce Physical Downlink Control Channel consumption,Increase the capacity of VoLTE, frequency spectrum service efficiency when increase channel conditions is good etc.
In a kind of possible embodiment, in the method that the embodiment of the present invention provides, trigger condition comprise withOne of lower condition or combination:
Condition one: current business is the speech business VoLTE based on Long Term Evolution LTE;
Condition two: the carrying that current business is used levels of quality of service identifier QCI to equal 1;
Condition three: current business is VoLTE business, and the QCI that this VoLTE business is used equalsThe data packet number arriving with predetermined period in 1 carrying is more than or equal to preset value;
Condition four: channel quality is more than or equal to first threshold.
For condition one, condition two, specifically, fix because VoLTE business has data package size,The feature that cycle is fixed and data package size is less, therefore, the fixed resource position of semi-persistent scheduling and largeThe little VoLTE business that is well suited for, current business is VoLTE, can adopt Semi-static scheduling method to carry outScheduling of resource, meanwhile, due to the carrying of VoLTE business use QCI=1, current business is used QCI=1Carrying, can adopt Semi-static scheduling method to carry out scheduling of resource. VoLTE business is used semi-persistent schedulingMethod can effectively reduce the expense of control signal to increase VoLTE capacity, meanwhile, and except VoLTE businessOutside other data services still use dynamic dispatching to improve frequency spectrum service efficiency.
For condition three, as specific embodiment comparatively, there is active period and quiet period in VoLTE business,In active period, VoLTE packet arrives taking 20 milliseconds of MS as the cycle, therefore, is applicable to employing half quietState scheduling, with the expense that effectively reduces control signal to increase VoLTE capacity; In quiet period, VoLTEPacket arrives taking 160MS as the cycle, therefore, is not suitable for adopting semi-persistent scheduling, and current business isVoLTE business, and arrive with predetermined period in the carrying of the QCI=1 that uses of this VoLTE businessData packet number is more than or equal to preset value, can adopt Semi-static scheduling method to dispatch, preferably,Predetermined period is 20MS.
It should be noted that, in the carrying of the QCI=1 that this VoLTE business is used, arrive with predetermined periodData packet number be more than or equal to preset value, can improve configuration semi-persistent scheduling accuracy, avoid connecingReceive that a packet arriving with predetermined period just adopts semi-static configuration and occurs erroneous judgement, for example: defaultValue can be 5, and certainly, preset value can be determined or Use Defaults as the case may be.
For condition four, as specific embodiment comparatively, semi-persistent scheduling is owing to being subject to the control of physical layerActivate the impact of signaling format, maximum MCS can only use 15, therefore, particularly preferred at channel conditionTime, for example: when MCS is greater than 20dB, use semi-persistent scheduling can increase the PRB that PDSCH usesNumber, can reduce frequency spectrum service efficiency, therefore, is not suitable for adopting Semi-static scheduling method to carry out scheduling of resource,Also when the channel quality of current business is more than or equal to first threshold, can adopt Semi-static scheduling method to enterRow scheduling of resource, and use semi-persistent scheduling good time by reducing channel conditions, increase channel conditionsFrequency spectrum service efficiency when good.
