Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of method and radio network controller of high speed downlink packet access (High Speed Downlink Packet Access, referred to as HSDPA) multithread reprovision.
Background technology
Along with the continuous fast development of data service, HSPA (High-Speed Packet Access, high-speed packet access) technology is more and more general, and to the future development of multi-antenna multi-carrier-wave.Such as, 3GPP (The 3rd Generation Partnership Project, third generation partner program) R7 version has been introduced MIMO (Multiple-Input Multiple-Out-put, multiple-input, multiple-output) technology, make the NodeB (Node B) can be by double antenna from same community simultaneously to UE (User Equipment, subscriber equipment) send two transmission blocks, under good space environment, can improve data rate, under low spatial environment, provide velocity of wave to embark on journey advantage to UE.Subsequently, the R8 version of 3GPP has been introduced DC-HSDPA (Dual Cell-High Speed Downlink Packet Access, the high speed downlink packet access of double small district) technology, in R9 version, introduced double frequency-band DC-HSDPA, make NodeB from the different frequent points that has intersection to cover Liang Ge community, to send HSDPA data to UE simultaneously, improved the user's impression across whole cell coverage area.
When UE is in edge, two co-frequency cells and carry out soft handover or during More Soft Handoff, often serve HS-DSCH (High-Speed Downlink Shared Channel, high-speed downlink shared channel) limited ability of eating dishes without rice or wine of community, and non-service HS-DSCH community in Active Set also has available resources, if can allow non-service cell also send data to UE as another Serving cell, will greatly improve user's impression, thereby improve the data throughout of community.Therefore, the R11 version of 3GPP enters on the multithread technology of HSDPA.According to the node of shunting, distinguish, HSDPA multithread technology can be divided between the interior shunting of NodeB and NodeB to be shunted.
Report the standard of down-going synchronous state to be divided into two stages.For each, have the down link that activates upstream frequency, UE will carry out these two stages one time, and corresponding down-going synchronous primitive is also reported to high level.Physical layer indicates (english abbreviation is CPHY-Sync-IND) and physics step-out indication (english abbreviation is CPHY-Out-of-Sync-IND) two primitive to inform the synchronous regime of the down link that activates upstream frequency by physical layer synchronization.
When the foundation of high level startup dedicated physical channels, UE start synchronous flow process A or synchronous flow process AA, the first stage is activated, and downlink dedicated channels is thought that by high level setting up rear this first stage will continue 160ms.During this period of time, if following standard is satisfied, step-out is not reported, synchronously reported: at previous 40 milliseconds, UE estimates downlink physical control channel quality or from related service high speed descending sharing channel community, receives the quality of the transmitting power control domain fragment dedicated physical channel frames, and its mass value is better than threshold values Qin.When the downlink physical control channel mass measurement of 40ms does not complete, this standard hypothesis is not performed.Wherein, the value of Qin is by dependence test implicit difiinition.
At high level, think 160ms after downlink dedicated channels has been established, second stage starts.In this stage step-out be synchronously in the news as follows:
If arbitrary standard is satisfied below, step-out primitive CPHY-Out-of-Sync-IND is reported to high level, informs the descending step-out of UE:
Standard one: be false if upstream discontinuous transmits activation (UL_DTX_Active), the estimation cycle is previous 160 milliseconds.In this estimation cycle, if the Dedicated Physical Control Channel quality of UE estimation or also poorer than threshold values Qout from the value of the quality of the through-put power control domain of the fragment DPCH of primary/secondary service high-speed downlink shared channel reports step-out primitive.Wherein, the value of concrete Qout determines by dependence test is implicit;
Standard two: be true if upstream discontinuous transmits activation (UL_DTX_Active), the estimation cycle is previous 240 milliseconds.In this estimation cycle, if the quality of the Dedicated Physical Control Channel of UE estimation or also poorer than threshold values Qout from the value of the quality of the through-put power control domain of the fragment DPCH of primary/secondary service high-speed downlink shared channel, reports step-out primitive;
Standard three: all transmission channels are all used non-zero length CRC (Cyclical Redundancy Check, cyclic redundancy check (CRC)) match downlink dedicated data channel, and the circulation with non-zero of receiving recently 20 transmission blocks correcting CRC to be found be all CRC check failure.In addition, at previous 160 milliseconds, all reception pieces of CRC are corrected in all circulations of adhering to non-zero length, and its CRC check is all incorrect, reports step-out primitive.
For DPCH, if arbitrary criterion meets, use synchronization primitives CPHY-Sync-IND to report to upper strata synchronous regime below:
Standard one: on 160 previous millisecond periods, the value of the downlink physical control channel quality of UE estimation is better than threshold values Qin, reports synchronization primitives;
Standard two: all transmission channels are all used non-zero length CRC to match downlink dedicated data channel, at certain TTI of present frame (Transmission Time Interval, while Transmission Time Interval) finishing, the transmission block of the circulation of at least one non-zero correction CRC is that CRC check is correct, reports synchronization primitives.If do not have transmission block to be received, or the transmission block that does not have the circulation of non-zero to correct when certain TTI of present frame finishes to have the circulation of a non-zero to correct CRC in the transmission block of CRC and previous 160 milliseconds is that CRC check is correct, just supposes that this standard meets.If the transmission block no one of the circulation of non-zero correction CRC receives in previous 160 milliseconds, this standard is also supposed to meet.At TFCI (Transport Format Combination Indicator, in situation about transport format combination identifiers) not used, for the circulation of not using non-zero in all transformats, correct CRC and do not use the transmission channel of the detection of guide property, this standard is not considered.
For fragment DPCH, if following arbitrary standard meets, report synchronization primitives CPHY-Sync-IND to high-rise:
Standard one: be false if upstream discontinuous transmits activation (UL_DTX_Active), on 160 previous millisecond periods, the quality of the through-put power control domain of the fragment DPCH from service high-speed downlink shared channel of UE estimation is better than threshold values Qin.Wherein, Qin determines by dependence test is implicit;
Standard two: be true if upstream discontinuous transmits activation (UL_DTX_Active), on 240 previous millisecond periods, the quality of the through-put power control domain of the fragment DPCH from service high-speed downlink shared channel of UE estimation is better than threshold values Qin.Wherein, Qin determines by dependence test is implicit.
Before introducing HSDPA multithread, for downward special physical channel and two scenes of fragment DPCH, defined respectively step-out behavior and reported.For the UE that has configured downward special physical channel, step-out standard is to estimate on all downlink data physical channels.For the UE that has configured downlink dedicated fragment physical channel, step-out standard is only on the fragment down physical channel of service high-speed downlink shared channel community, to estimate.Introduce after multithread, current industry is reached common understanding, and is exactly that step-out and synchronous judgement flow process are constant, continues to use the criterion of the synchronous and step-out of non-multithread.For the UE that has configured multithread and downward special physical channel, industry its step-out behavior of reaching common understanding.But for the UE that has configured multithread and descending fragment DPCH, in order to improve the operation of UE and to reduce unnecessary Radio Link Failure, ductile step-out and synchronous criterion have been proposed.Because if the estimation of the fragment DPCH still based on service high-speed downlink shared channel step-out, decides Radio Link Failure, seem a little too fierce, because UE and assistance services tell DSCH Downlink Shared Channel community keeping contacting in signaling.So-called step-out of extending and synchronous criterion, tell UE to carry out descending step-out estimation in service and assistance services respectively, and when Qie Dangliangge community all meets descending step-out standard separately, descending step-out flow process is triggered.When step-out, if share community or meet synchronization criterion from the fragment DPCH in assistance services high-speed downstream community from service high-speed downlink, step-out flow process is stopped, and is descendingly considered to synchronous.Follow-up further discussion, thinks that this ductile step-out and synchronous criterion there is no need to introduce, and think that gain is little.This ductile criterion is to be based upon the signal scene better than the signal quality of Serving cell of assisting community, and this is infrequent conventionally, because mobility principle regulation Serving cell is all the best community of signal quality conventionally.Even if this scene has occurred, assist community can not change the configuration of terminal, data are not parked in Serving cell and send, and Serving cell step-out, the gain that has not had multithread to bring.Because terminal can not start cell update flow process, even can enter a deadlock state again.So original step-out and synchronous criterion are still used in suggestion, the step-out based on Serving cell and synchronous judgement, to better start cell update flow process, allow network side know earlier the situation of current wireless link, for terminal is carried out new suitable configurations.
The main cause of descending step-out is that wireless environment is bad, interference, weak covering etc.In non-multithread situation, multilink can transmit identical data flow.When a link synchronization failure, data are communicated to UE by good wireless link, and the wireless link of step-out can be deleted by measurement procedure.When all down link step-outs or service link step-out, can recover by cell update (cell update) process, guarantee not call drop as far as possible.
Multithread is to transmit different data flow at different links.When assisting the descending step-out of link, on the good service link that the data flow that transmission is not gone down can be rescheduled to, transmit.The service link that the data flow of not going down for transmission is rescheduled to, industry is introduced new high speed Shared loss indication control frame, this frame sends RNC (Radio Network Controller to by NodeB, radio network controller), inform the reason of loss, comprise: oversize overtime non-successful HARQ (the Hybrid Automatic Repeat Request that causes of time delay, T1 in the buffering area of MAC-hs or MAC-ehs entity, mixed automatic retransfer request) or TNL (Transport Network Layer, transport network layer) stop up.Descending step-out can cause in the entity buffering area of MAC the data residence time long, will trigger like this NodeB reporting high speed Shared loss indication control frame to RNC, and RNC can be used this Frame indication NodeB to preserve or abandon given protocol Data Unit.If abandoned, the service link that original data flow will be rescheduled to.The assistance wireless link of this step-out needs to wait for that measurement procedure deletes, but down-going synchronous failure do not mean that and leave Active Set, so the wireless link of the assistance community of down-going synchronous failure exists always.If assist wireless link synchronization failure corresponding to community, can not upgrade in time and report, cause the network side configuration that can not upgrade in time, and then cause the waste of resource.
As shown in Figure 1, balance control method across the data traffic of Tong Pin double small district's multithread of NodeB (being called for short SF-DC), comprise: the descending step-out of wireless link between NodeB1 and UE, while causing the data of NodeB1 not send UE in time, RNC can send the data dispatch of NodeB1 to NodeB2.But in order to maintain business, up link exists always, possible signal neither be fine for NodeB1, NodeB1 side can receive the channel quality indication that UE reports always, by NodeB1, estimate certain ability capability value to RNC, RNC can send data to NodeB1 again, and the data of NodeB1 side transmit to go down for the second time, and the data dispatch that RNC side can not transmit down NodeB1 again transmits to NodeB2.Go round and begin again, caused the waste of complexity and the resource of data transfer procedure.This is mainly because RNC can not be known step-out and cannot recover caused of a certain link in time.
The out-of-step operation judgement Main Basis of multithread is at present in the wireless link relevant to Serving cell, to assisting the relevant wireless link in community whether synchronously there is no relevant criterion and operation.But assisting the descending step-out of the wireless link that community is relevant is objective reality, and its performance is exactly not receive high-speed physical shared channel, being reacted to up feedback is exactly not transmit, and has the data residence time long in the buffering area of MAC entity, even cannot send.
