Abstract
The invention discloses a downlink cache data reporting method. According to the method, after an RLC obtains DRX configuration information of UE, the DRX working period and the DRX activation period of the UE are determined according to the DRX configuration information, and the downlink cache data reporting moment of the UE is set according to DRX working period; when sub frame interruption occurs, only downlink cache data of the UE in the DRX working period are reported according to the downlink cache data reporting moment of all UE. In this way, the phenomenon that transmission delay is prolonged due to the fact that the UE in the DRX activation period seizes the reporting number of the downlink cache data size is avoided, and the user experience is effectively guaranteed under the condition that a terminal starts a DRX power-saving mode.
Description
Technical field
The present invention relates to communication technical field, particularly a kind of down buffer storage data reporting method.The present invention also relates to a kind of Radio Link Controller RLC simultaneously.
Background technology
At present, LTE (Long Term Evolution, Long Term Evolution) RRC (Radio ResourceControl in system, wireless heterogeneous networks) layer is UE (User Equipment, subscriber equipment) be all configured with DRX (Discontinuous Reception, discontinuous reception) function, make UE can discontinuous monitoring PDCCH (Physical Downlink Control Channel after unlatching DRX function, Physical Downlink Control Channel) channel, thus reach the object of saving power for terminal.After unlatching DRX function, UE determines whether to monitor PDCCH according to current DRX state, and performs corresponding data transmit-receive, and network side (eNB, base station) is then according to the DRX state operation dispatching of UE, and carries out corresponding data transmit-receive.
As the performance that emphasis in prior art instantly promotes, the application of DRX spreads all over various scene, and as important measures of saving power for terminal and means, under DRX, the handling property of equipment also becomes the focus of concern, the additional transmissions time delay especially occurred owing to adopting DRX.
For prior art, LTE protocol specifies can be the UE being in " RRC_CONNECTED " state and configures DRX function.A DRX cycle is made up of two parts:
1. duration of work (On Duration)
UE monitors PDCCH during this period, for receiving descending PDSCH (Physical DownlinkShared Channel, Physical Downlink Shared Channel) data and obtain uplink scheduling, carry out PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel) transmission, belong to the DRX inactive phase;
2.DRX active period
The reception that UE can skip down channel during this period reaches the object of saving electricity.
ENB side is by judging whether this UE enters DRX, if UE has been in the DRX phase, base station will no longer be dispatched this UE; If be in duration of work, then this UE of normal consistency.
In current LTE system, the realization flow of scheduling is as follows:
1. receive PDCP (Packet Data Convergence Protocol, PDCP) SDU (Service Data Unit, Service Data Unit) of layer, judge that UE connects surface location residing for current, if be BO layer to be refreshed, no longer process; If empty BO layer, user is moved into layer to be refreshed.
2., when subframe is interrupted, obtain even top layer user to be refreshed, according to the strategy of poll, calculate the BO information of UE successively, and be assembled into message
3. chain top layer has traveled through, or having met RLC Up Date Bo Num configures, and carries out BO information reporting.
In above flow process, suppose that RLC once can only to the buffer data size of MAC (Media Access Control, medium access control) dispatch notification 50 users, and number of network users is 100, wherein 50 users are in DRX active period, and other 50 are in DRX duty cycle.Because RLC is (Radio LinkControl, wireless link controls) do not consider DRX functional characteristic, once report middle RLC to be 50 and be in the reporting of user of DRX active period downlink data buffer memory, other 50 users being in DRX duty cycle are not reported any downlink data buffer memory, so do not dispatched owing to there being the user of downlink data buffer memory to be in DRX active period at current time, although other 50 users are in DRX duty cycle, but because there is no down buffer storage data, still can not be scheduled, thus current time base station does not have any scheduling.Thus waste interface-free resources, increase propagation delay time.
As can be seen here, in the implementation procedure of LTE base station product, the down buffer storage data volume of each UE informs MAC layer scheduler by rlc layer.The general mode adopting periodically timing notice; along with the commercialization of TD-LTE and scale expand rapidly; in base station, the UE number of access sharply increases; consider that the frequent degree of information interaction is on the impact of properties of product, usually can limit RLC in each cycle and inform the UE number of MAC scheduler down buffer storage data volume.For the situation of not opening DRX function, the UE of all available for transmission data of poll sequentially; But for opening the situation of DRX function, if still according to sequencing poll, then likely cause notifying that the UE of down buffer storage data volume is in DRX active period and cannot dispatches, and the UE being in the DRX inactive phase that can dispatch does not inform down buffer storage data volume the situation of MAC scheduler, thus cause the ensemble average stand-by period of downlink data transmission to increase, have influence on Consumer's Experience.

Embodiment
As stated in the Background Art, in notice down buffer storage data volume UE number limited within each cycle, notify the current user that can dispatch of MAC scheduler as far as possible in time, have very important effect for the unnecessary data transmission delay of shortening.Therefore the present invention proposes a kind of down buffer storage data reporting method.The DRX configuration information of each UE of RLC is informed by MAC, wherein DRX configuration information comprises DRX skew, UE can be calculated according to DRX skew to be between DRX active period and to be still in DRX duration of work, RLC is linked into corresponding storage of linked list to UE according to DRX configuration, be in the UE between DRX active period, MAC scheduler down buffer storage data volume will not be reinformed.Map out the UE being in the DRX inactive phase according to current radio half frame number, carry out downlink data amount and report, with this more timely and accurately for MAC scheduler provides the information needed for scheduling and resource.
As shown in Figure 1, the method specifically comprises the following steps:
The noncontinuity that S101, Radio Link Controller RLC obtain user equipment (UE) receives DRX configuration information.
In order to the chain surface location confirming the current place of UE can be convenient to, in the preferred embodiment of the invention, first RLC receives user from media control MAC is the DRX configuration information that described UE is arranged, and described DRX information is described MAC is that the DRX configuration that described UE is arranged is assembled into information and sending to described RLC's by RRC when described UE link setup.Afterwards, RLC, according to the DRX skew of carrying in described DRX configuration information, configures the chain surface location inquiring about the current place of described UE in map index table, and is stored to by Query Result in pre-configured user configuration information storage list at pre-configured DRX.
Between the DRX duration of work that S102, described RLC determine described UE according to described DRX configuration information and DRX active period, and report the moment according to the down buffer storage data that described DRX duration of work arranges described UE.
In the preferred embodiment of the invention, described UE after the Service Data Unit SDU receiving PDCP PDCP layer, according to the DRX configuration information of described UE, is configured at the chain top layer corresponding with described DRX configuration information especially by RLC by this step; Described DRX chain top layer is set up in advance according to current already present dissimilar DRX configuration information.
Particularly, for processing procedure UE being put into the chain top layer corresponding with its DRX configuration information, first the chain surface location at the current place of described UE is determined according to described user configuration information storage list, and determine whether described UE configures DRX according to described DRX configuration information, process respectively according to following situation subsequently:
(1) if described UE is current be in arbitrary DRX chain top layer, or described UE is current is not in any DRX chain top layer and does not configure DRX, then end process;
(2) be not in any DRX chain top layer if described UE is current and configures DRX, described UE is inserted described corresponding with described DRX configuration information DRX chain top layer.
S103, when subframe occurring and interrupting, described RLC reports the moment according to the down buffer storage data of current each UE, only reports the down buffer storage data of the UE being in DRX duration of work.
In the preferred embodiment of the invention, for the deterministic process in this step, first described radio half frame number is obtained from driving, in half pre-configured frame number map index table, inquiry and described radio half frame number corresponding DRX chain top layer, finally report down buffer storage data according to described DRX chain top layer.For reporting this process of down buffer storage data, concrete steps are as follows:
Travel through described DRX chain top layer, judge whether the quantity of the UE in described DRX chain top layer meets the pre-configured number of users configuration carried out down buffer storage data and report;
If meet, carry out reporting of down buffer storage data according to described DRX chain top layer;
If do not meet, using lower one deck DRX chain top layer on described DRX chain top layer as new DRX chain top layer, report down buffer storage data according to described new DRX chain top layer.
In order to set forth technological thought of the present invention further, now in conjunction with concrete application scenarios, technical scheme of the present invention is described.For ease of describing, follow-uply reported by RLC the process of down buffer storage data to be called to report BO, follow-up mention report BO namely to refer to RLC reports down buffer storage data to MAC scheduler.Below first design starting point of the present invention will be introduced:
1. configure according to the DRX of UE, receive SDU and in time UE is put into corresponding position, refresh with the BO reducing invalid UE and report, carry out corresponding UE in time and dispatch and data transmission.Therefore configure based on DRX the BO reported to dispatch, more mating the dispatch deal of MAC layer, decrease the treating capacity of system, is that treatment effeciency is higher, and what reduce the time delay of user and largeizationr make use of Radio Resource.
2., at the BO reporting user in intersecting chain top layer, comprehensively consider different scene as far as possible, objective and accurate, expanded by BO and report and the configuration of upper count off, effectively prevent the wasting of resources because user's deficiency causes, decrease the processing load of MAC.
Setting out based on these considerations, carry out BO reporting policy based on DRX configuration, by obtaining DRX configuration, calculating the BO queue that each wireless sub-frame reports, and refresh number of queues by dynamic adjustment, muchly maximizedly utilize resource, raise the efficiency.
Conveniently carry out storage and the judgement of the UE of DRX difference configuration, report to carry out BO selectivity more fast and accurately, eNB side is provided with several map index table and Configuration Values for this reason:
(1) RlcDrxOffsetMap:DRX configures map index table.In the UE configuration messages that RLC sends according to MAC, DRX skew, inquires UE place chain table position from mapping table.
(2) RlcHalfToUeListPos: half frame number map index table.When breaking in each subframe, RLC obtains current invalid half frame number, inquires about chain top layer to be refreshed by mapping table.
(3) RlcRlInfo: user configuration information storage list.The DRX configuration that store M AC sends, and use when receiving PDCP SDU.
(4) RLC_DRX_UE_QUE:DRX chain top layer.RLC configures according to DRX, UE is put into corresponding chain top layer, is convenient to quickly look-up and refreshes.
(5) RlcUpDateBoNum: refreshes user number configures.RLC, according to configuration, refreshes the BO of the user of every subframe specified quantity, to reduce traversal and to take into account the configuration of MAC system throughput.
(6) RlcBoRptExtern:BO reports expanded configuration.When current DRX configuration connects UE number deficiency in top layer, RLC is according to configuration, and dynamically the BO of newly-increased part UE refreshes.
By searching and refreshing mapping table above, RLC in time, accurately can judge the DRX configuration that UE is current and state, thus notifies that MAC carries out the scheduling of associated user efficiently, accurately.
Based on above-mentioned setting, first RRC is the DRX of UE configuration at UE link setup MAC in season by the present invention, be assembled into message and be sent to RLC, receive the SDU of PDCP layer subsequently, configure according to the DRX of UE, UE is put into corresponding even top layer, like this when interrupting when subframe, according to radio half frame number, by calculating and search the company top layer needing to refresh BO, the BO carrying out UE refreshes and reports.
Particularly, receive PDCP SDU handling process as shown in Figure 2, user configures DRX constantly, and the DRX configuration information of user is sent to RLC by MAC.After RLC receives configuration messages, the DRX configuration sent according to MAC, search RlcDrxOffsetMap, storing queries result is in RlcRlInfo.Receive the SDU of PDCP layer, judge that UE connects surface location residing for current, if be DRX layer, no longer process; If general position, according to stored configuration in RlcRlInfo, configure DRX, UE is inserted the RLC_DRX_UE_QUE of corresponding configuration, otherwise UE is constant by holding position.
BO reports handling process as shown in Figure 3, when subframe is interrupted, obtains current wireless half frame number from driving, and by calculating and searching RlcHalfToUeListPos, find the RLC_DRX_UE_QUE needing to refresh BO, the BO carrying out UE refreshes and reports.Chain top layer has traveled through, and has met RlcUpDateBoNum configuration, has carried out BO information reporting; If also do not met, check that current RlcBoRptExtern configures, if configuration is opened, proceed the traversal of lower one deck RLC_DRX_UE_QUE, until meet RlcUpDateBoNum configuration; Configuration is not opened, and is directly reported by the BO of the user of current refreshing.
By performing above flow process, suppose that RLC once can only to the buffer data size of MAC dispatch notification 50 users, and number of network users is 100, wherein 50 users are in DRX active period, and other 50 are in DRX duty cycle.Because RLC considers DRX functional characteristic, the reporting of user downlink data buffer memory once reporting middle RLC only for being in DRX duty cycle, the user being in DRX active period is not reported downlink data buffer memory, can be so only 50 reporting of user down buffer storages being in DRX duty cycle at current time RLC, thus whole 50 downlink datas being in the user of DRX duty cycle can be transmitted in time.Other 50 users are owing to itself being in DRX active period, and no matter whether they have down buffer storage data to be transmitted, should not be transmitted downlink data.
In order to reach above object, the invention allows for a kind of Radio Link Controller RLC, as shown in Figure 4, comprising:
