Description
Technical field
The present invention relates to the communications field, relate in particular to the high-rise network element of processing method, config update method, MAC entity and the network side of the descending step-out of a kind of link.
Background technology
Along with the continuous fast development of data service, high-speed data packets access (HSPA) technology is more and more general, and to the future development of multi-antenna multi-carrier-wave.Such as, the R7 version of third generation partner program (3GPP) has been introduced multiple-input and multiple-output (MIMO) technology, make base station (NodeB) to send two transmission blocks to UE from same community by double antenna simultaneously, 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 two carrier wave high speed downlink packet access (DC-HSDPA) technology, in R9, introduce double frequency-band DC-HSDPA, make NodeB to send high speed downlink packet access (HSDPA) data to subscriber equipment (UE) from the different frequent points that has intersection to cover Liang Ge community simultaneously, improved the user's impression across cell coverage area.
When UE is in edge, two co-frequency cells and carry out soft handover or when More Soft Handoff, the often limited ability of eating dishes without rice or wine of serving high speed downlink shared channel (HS-DSCH) community, and non-service HS-DSCH community in Active Set also has available resources, if can allow non-service cell also as another Serving cell, send out data to UE, will greatly improve user's impression, thereby also improve the data throughout of community.Therefore, the R11 version of 3GPP enters on the multithread technology of HSDPA.Distinguish according to the node of shunting, HSDPA multithread technology is 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; Have for each 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 (CPHY-Sync-IND) and physics step-out instruction (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 high level starts, dedicated physical channels is set up or UE starts synchronous flow process A or synchronous flow process AA, and the first stage is activated, and descending dedicated channel is thought that by high level setting up rear this first stage continues 160ms.During this period of time, if following standard is satisfied, step-out is not reported, is synchronously reported:
At previous 40 milliseconds, UE estimates downlink physical control channel quality or receives the quality of the transmitting power control domain fragment dedicated physical channel frames from related service high speed descending sharing channel community, if its quality is better than threshold values Qin.Not completing of the downlink physical control channel mass measurement of 40ms, this standard hypothesis is not performed.Qin is by dependence test implicit difiinition.
Think 160ms after descending dedicated channel has been established when high level, 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:
If-upstream discontinuous transmits and activates (UL_DTX_Active) is false, the estimation cycle is previous 160 milliseconds.UE estimation Dedicated Physical Control Channel quality or the quality from the through-put power control domain of the fragment DPCH of primary/secondary service high-speed downlink shared channel in this cycle, its mass value is also poorer than threshold values Qout, and concrete Qout determines by dependence test is implicit;
If-upstream discontinuous transmits and activates (UL_DTX_Active) is true, the estimation cycle is previous 240 milliseconds.UE estimation Dedicated Physical Control Channel quality or the quality from the through-put power control domain of the fragment DPCH of primary/secondary service high-speed downlink shared channel in this cycle, its mass value is also poorer than threshold values Qout, reports step-out primitive;
-all transmission channels all use non-zero length cyclic redundancy check (CRC) code (CRC) to match downlink dedicated data channel, and 20 transmission blocks that CRC is corrected in the circulation with non-zero of receiving are recently found to be whole CRC check failures.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:
-on 160 previous millisecond periods, the downlink physical control channel quality of UE estimation is better than threshold values Qin, reports synchronization primitives;
-all transmission channels all use non-zero length CRC to match downlink dedicated data channel, in the time that certain Transmission Time Interval (TTI) of present frame finishes, the transmission block of the circulation correction CRC of at least one non-zero is correct by CRC check, reports synchronization primitives.If do not have transmission block to be received, or the transmission block that finishes not have the circulation of non-zero to have in correcting the transmission block of CRC and previous 160 milliseconds the circulation of a non-zero to correct CRC at certain TTI of present frame is correct by CRC check, 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.In the situation that transport format combination identifiers (TFCI) is not used, for not using the circulation of non-zero to correct and do not use the transmission channel of the detection of guide property in all transformats, this standard is not considered.
For fragment DPCH, if following arbitrary standard meets, report synchronization primitives CPHY-Sync-IND to high-rise:
If-upstream discontinuous transmits and activates (UL_DTX_Active) is false, 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, and Qin determines by dependence test is implicit;
If-upstream discontinuous transmits and activates (UL_DTX_Active) is true, 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, and Qin determines by dependence test is implicit.
Before introducing HSPDA multithread, define respectively step-out behavior for downward special physical channel and two scenes of fragment DPCH and reported.For having configured downward special physical channel, step-out standard is the estimation on all downlink data physical channels.For the UE that has configured descending fragment DPCH, 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 synchronous and step-out criterion of non-multithread.For the UE of configuration multithread and downward special physical channel, industry its step-out behavior of reaching common understanding.But for configuration multithread and descending fragment DPCH, in order to improve the operation of terminal and the Radio Link Failure that minimizing there is no need, ductile step-out and synchronous criterion are proposed.Because if the estimation of the fragment DPCH still based on service high-speed downlink shared channel step-out, determines 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.In the time of 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, is all the best community of signal quality conventionally because mobility principle specifies Serving cell.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 step-out of Serving cell, 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 suggestion is still used original step-out and synchronous criterion, 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, carries out new suitable configurations to terminal.
Descending step-out main cause is that wireless environment is bad, disturbs weak covering etc.In non-multithread situation, multilink transmits 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.All down link step-outs or service link step-out, can recover by cell update (cell update) process the call drop of trying not.Multithread is to transmit different data flow at different links.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 instruction control frame, this frame sends radio network controller (RNC) to by nodeb, informs the reason of loss: oversize time delay in the buffering area of MAC entity; T1 is overtime, and HARQ's is unsuccessful; TNL stops up.Descending step-out can cause the data residence time in the buffering area of entity of MAC long, will trigger like this and report nodeb reporting high speed shared channel to lose instruction control frame to RNC, RNC can use this control frame instruction 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 waits 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 community corresponding wireless link synchronization failure, can not upgrade in time and report, cause the network side configuration that can not upgrade in time, cause the waste of resource.For example in Fig. 1 across balanced control of data traffic of same frequency double small district's multithread of nodeb (being called for short SF-DC), the descending step-out of wireless link between nodeb1 and UE, cause the data of nodeb1 can not send in time UE to, RNC can be rescheduled to the data of nodeb1 nodeb2 and send.But in order to maintain, business is up to be existed always, possible signal neither be fine for nodeb1, nodeb1 side can receive the channel quality the reporting instruction from UE always, but nodeb1 can estimate certain ability capability value to RNC always, then RNC can send data to nodeb1, the data of nodeb1 side can not transmit down for the second time, 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; Main cause is exactly that RNC can not know that step-out and the reason that cannot recover cause a certain link in time in fact.
