Description
The application be that April 2, application number in 2003 are 03807731.0 the applying date, name is called the dividing an application of Chinese patent application of " subscriber equipment and the method that help high speed-downlink shared channel cell change ".
Technical field
The present invention relates to field of wireless communication.More particular words it, the present invention relates to recover effectively buffered data in the wireless system of intermediate point distribute data, switching the back.Comprise the telecommunication network controller (RNC) that is coupled on one or more Node B and utilize adaptive modulation and coding (AMC) and mix the third generation (3G) system that asks (H-ARQ) technology of heavily referring to automatically (wherein said one or more Node B again wireless type be coupled on a plurality of subscriber equipmenies (UE)) successively and only be an example of this kind system.
Background technology
The third generation (3G) universal terrestrial radio access network (UTRAN) comprises several RNC, and wherein said each RNC all can be coupled on several Node B.Node B is the entity that comprises one or more base stations, wherein the flow of each one or more sub-district of BTS management.
3G frequency division duplexing (FDD) and this RNC of general using of time division duplex (TDD) system cushion and dispatch the data that (schedule) is transferred to this UE.Yet, with regard to the IA High Speed Channel of described 3G cellular system, be to cushion and dispatch the data that will transmit by Node B.One of them IA High Speed Channel for example is this high-speed downlink shared channel (HS-DSCH).This Node B of reason is come distribute data, so the data buffering that must will transmit is in Node B.This structure causes this RNC not obtain the last state of its control grouped data sub-district (PDU) transmission of this Node B.Therefore, in case when switching, then must coordinate the scheduling of described transfer of data with regard to this cell change in the minizone.Not so, then must be behind this cell change, " leakage " or " repeats transmission to make transfer of data synchronization again, with the data of avoiding transmitting ".In 3G network, the switching of minizone is by this RNC control.Because of the RNC that is used for controlling the sub-district that comprises this UE can change, so data might miss or repeat because of this switching.Because each RNC is associated with several Node B in this structure, causes this problem more serious.Because the switching of UE sub-district is greater so the possibility that mobile UE requires Node B to change requires RNC to change more than it.
This HS-DSCH utilizes AMC to start high speed transmission data, and utilizes H-ARQ to increase the possibility of successful Data transmission.This UE transmitting and when receiving the cell associated of UTRAN access point of this service HS-DSCH Radio Link, then causing serving the HS-DSCH cell change when must change this.When the replacement sub-district recognizes that physical channel condition and/or entity capacity improve, then cause this service HS-SDCH cell change.Be different from other channel in the 3G network, this HS-DSCH interrupts on interruption on the Node B rather than the RNC in this UTRAN.
Two kinds of HS-DSCH cell change types are arranged.When this UE changes two minizones that are associated with this same Node B, then be the service HS-DSCH cell change in the Node B.When this UE changes two minizones that are associated with different nodes B, then be the service HS-DSCH cell change between a Node B.With regard to cell change between Node B, the Node B before this service HS-DSCH cell change is called this source node B; And will serve the HS-DSCH cell change after Node B be called this target node b.
All have among this RNC and this UE with layer Radio Link control (RLC) entity, provide as heavily referring to automatically of data of transmission and ask (ARQ) function.This transmission RLC entity sends sequence number (SN) in this PDU header with signal, and wherein this reception RLC entity utilizes this sequence number to guarantee not missing any PDU between this transmission period.When between this transmission period, having missed some PDU (because of not transmitting in order due to the PDU), then this reception RLC entity transmit a PDU status report, to notify this transmission RLC entity " some PDU has missed ".Utilize this PDU status report that the state of this transfer of data is described.Wherein this PDU status report is discerned described leakage or the sequence number SN of the PDU that receives.As missed PDU, then the duplicate of this transmission RLC entity PDU that this can be missed is transferred to this reception RLC again.
This transmission RLC entity also may receive RLC entity poll pdu status report to this; Or may produce status report termly.This poll provides a mechanism, supplies the state of the described PDU transmission of this transmission RLC entity requests.
The H-ARQ function of this Node B also provides the function that failed transmission is transmitted again again.Though this H-ARQ operation meeting removes and improve the probability of successful Data transmission with the transmission of some failure, what transmit is this rlc protocol layer yet assure success at last.
Since the dynamic change of propagation conditions, this HS-DSCH cell change must be carried out apace, with the maintenance service quality.During this service HS-DSCH cell change, this UE might stop this coming transmission in the cell-of-origin and reception, when having transmitted all and be stored in PDU in this source node B at present till.Because of this data are dispatched and cushioned to this source node B, and because of described message transmission rate very high (for example 10,000,000 bps or higher), so (the particularly switching between Node B), the data that are buffered in this source node B in a large number might be missed when this UE carries out service HS-DSCH cell change.One of them is former because do not provide any mechanism in order to the buffered data on this source node B is transferred to this target node b in this UTRAN structure.In case HS-DSCH is provided cell change, then because of fail to give notice this RNC " data transmission scheduling of Node B ", so how many data loss this RNC does not know to have fall (if the words that have), and this RNC does not also know whether this UE has and successfully recovers to confirm this transmission.So in case after the HS-DSCH cell change is provided, when still having data buffering in this source node B, then this RNC RLC must recover these data, these data of unlikely leakage to keep transmission.
At present, prior art systems has two kinds of preferable modes to recover buffered data on this source node B.Promptly behind this HS-DSCH cell change: 1) this RNC can be clearly to this UE request PDU state; Or 2) this RNC can be only come to meet with the cell-of-origin stopping place to begin transmission from this, and this UE examines not transmitting in order of knowing by it and will produce this PDU state.
In this first kind of situation, with request PDU state clearly, this RNC must wait until earlier in this new sub-district and set up till this physical channel this RNC by this UE of poll.Then, this RNC transmits this PDU state request, and this UE receives and handle this request.This UE produces this PDU state, and this PDU state is returned to this RNC, and wherein this RNC handles this PDU state and determines which PDU needs transmission again.
In this second kind of situation, this RNC only comes to meet with the cell-of-origin stopping place to begin to transmit PDU from this, and these data of not transmitting in order of this UE identification are returned to this RNC with generation PDU state.This RNC handles this PDU state and learns which PDU needs transmission again.
In above-mentioned two kinds of situations any when recovering buffered data in this source node B as need, then can remove to handle the PDU state; Yet, but seriously incured loss through delay the time that this UE its suitable reception is transmitted data again.This is to produce the time of this PDU state because of having incured loss through delay this UE, thereby has incured loss through delay the time that this RNC receives this PDU state.
When recovering at RLC to carry out transmission under the affirmation mode, then when Data transmission in proper order, just send data to higher level.In this way, can require this UE cushion these not sequenced data, in the time can transmitting the PDU of described omission again till.This has not only incured loss through delay this transmission, also require simultaneously this UE have internal memory even as big as buffered data, till can successfully transmitting the data that are stored in this source node B.Otherwise this effective speed can reduce, thereby influences service quality.Because of internal memory is very expensive, so be design limit condition improperly.
In this way, the described art methods of recovering this buffered data before the buffered data with source node B is transferred to target node b, earlier can produce extremely bad consequence.A kind of buffered data that this source node B of efficient recovery can more be arranged in the short period of time, be more desirable with the system and method for suitable maintenance customer's service quality demand.
Summary of the invention

Embodiment
Will be with regard to described graphic explanation preferred embodiment of the present invention, wherein in all are graphic, the assembly of same number TYP.
According to the present invention, for behind this service HS-DSCH cell change, shorten the stand-by period that this RNC obtains described PDU state and recovers the buffered data of this source node B, so after having notified this indicated HS-DSCH cell change of this RRC program, this UE just autonomously sends described PDU state to this RNC.Each AM RLC example that the PDU state of this generation can be used for be associated with this HS-DSCH transfer channel.
With reference to the flow chart of figure 1, illustrate a kind of according to the present invention, the effective method 10 of the buffered data of recovery nodes B.This RNC picks out need provide this HS-DSCH cell change (step 12).Then, notify this Node B " this service HS-DSCH cell change " (step 14).Notify this UE " this service HS-DSCH cell change " (step 16), as indicated via this RRC request message.Also note that may be before step 14 first invocation step 16 and do not have any disadvantageous consequence.
When in case this UE has received this RRC request message (step 18), this UE promptly behind indicated this HS-DSCH cell change of notified this RRC program, produce the status report (step 20) of this RLC PDU state of indication as early as possible, when recovering the buffered data of this source node B, to shorten time of delay.This UE do not wait in this arbitrary prior art in order to the triggering that produces the PDU state (for example this RNC request produce the PDU state, also or this UE detect not Data transmission in order).
This UE can carry out many different alternative methods, produces the PDU status report to cause behind service HS-DSCH cell change.Yet several embodiment are proposed in this.Preferably, select as first, in case when having removed the buffering area of this its rearrangement of high speed medium access control system (MAC-hs), this MAC-hs just notifies this RLC.Second is chosen as this RRC notifies this RLC " to indicate the 3rd layer of (L3) RRC program of this service HS-DSCH cell change ".The 3rd, this physical layer can notify this RLC " to receive the HS-DSCH control channel in this Target cell "; In case or HS-DSCH when controlling transitions to this Target cell, this physical layer can notify this RLC.Those skilled in the art must can be appreciated that the method that other is also arranged can be in order to trigger desire sends this RNC to from this UE RLC PDU status message.Since this program, produce this PDU state in the short period of time and send this PDU state to this RNC (step 22), thus cause more effectively recovering the buffered data of source node B.
According to step 22, there are several to select to send this PDU status report to this RNC for this UE.The method of this PDU state of described transmission is for this UE can be how sends the embodiment (non-pre-requisite of the present invention) of this PDU state to this RNC with signal, wherein is explanation in case when new criterion is arranged, promptly produce the PDU state.Preferably, this UE produces the RLC status report for the AMRLC example that each is mapped on this HS-DSCH transfer channel.
In second selects, when in a single day this UE obtains the PDU status report, promptly send this PDU status report to this RNC from this UE " via this first current uplink message.With regard to service cell change in the Node B (and supposing that this HS-DSCH transfer channel and radio bearer parameter do not change), the message on this DCCH is " physical channel is reshuffled and finished ".As this HS-DSCH transfer channel with radio bearer parameter has changed and/or with regard to Serving cell between Node B changed, the message on this DCCH was " transfer channel is reshuffled and finished ".Can in any RRC signaling message, discern this PDU state.Then, this RNC RRC entity notify this RLC " state of described PDU ", to continue to be transferred to this target node b again.
In the 3rd selected, this UE sent the status report that this relevant DCCH goes up new L3 signaling message to this RNC from this UE.This new information is sent to the rrc layer of this RNC from Radio Resource control (RRC) layer of this UE.Then, this RNC notify this rlc layer " state of described PDU ", to continue to be transferred to this target node b again.In this way, the PDU status message shown in this Fig. 1 can comprise two different message " RRC " and " RLC state ".
The special format that note that this PDU status report can change.For example, the form of described PDU status report can comprise: 1) this sequence number (SN) of the PDU of the described last transmission of success in proper order; 2) this highest sequence number SN of the PDU that receives of described success; 3) the sequence number SN of the described PDU that does not successfully receive (i.e. leakage fall PDU), this highest sequence number SN of the wherein paramount PDU that receives to described success; 4) or one list reach the sequence number tabular of the PDU that merit receives.
In case when this RNC received with the message of this PDU state, then this RNC RLC handled this PDU status message (step 24), to determine the PDU of described leakage.This RNC recognizes the data of missing because of this cell change now, and the data of this leakage can be transferred to again this UE (step 26).Note that this message can have many kinds, and may not only it be limited in " with this PDU status report ".
Also note that in this specific embodiment of the present invention this RNC can be in step 16 and 24 data that continue will be transferred in this Target cell of transmission this UE.Because of as when successfully not transmitting the data of all bufferings on the source node B, the order of these data will disorderly fall, so can force this UE RLC to cushion these data, make data can pass to higher level in proper order.This requires this UE to have an internal memory that enough stores the chaotic PDU of described order.After having missed any data in proper order, then transmission is to be limited on the memory power of UE, till the data in proper order of successfully having transmitted this leakage.
Refer now to the flow chart of Fig. 2, illustrate a kind of according to the present invention another specific embodiment, the effective method 40 of the buffered data of recovery nodes B.Method 40 is similar to method shown in Figure 1 10, and the mark of the described step of Fig. 2 and Fig. 1 are identical.Yet, this specific embodiment according to the present invention, method 40 comprises a new step 17, wherein this RNC stop all down link HS-DSCH that lead to this UE wait upon defeated, till having handled this PDU status message (step 24).The time that this specific embodiment is postponed when making the buffered data that transmits source node B again is reduced to the shortest, and has limited the data volume that must be buffered on this UE.
With regard to this time of delay with regard to the shortizationest, this Node B is not also known the transmission sequence number of RLC, and the transmitting and scheduling in the Node B is based on first in first out (FIFO).Therefore, the RNC as this Target cell when just passing on data before this PDU state is processed, then can transmit this data earlier.The data of this formation in Node B might make the required time of the buffered data that transmits this source node B again longer.
The present invention is applicable to the HS-DSCH cell change in the cell change in cell change between Node B and the Node B.Because under the situation (case), the HS-DSCH data that this Node B can not will cushion owing to the indoor design problem are directed to this Target cell again in this Node B, this RNC can be designated as the needs that two kinds of situations produce the PDU states.This UE also possibly can't distinguish cell change and the interior cell change of a Node B between a Node B, gives between Node B and two kinds of examples in the Node B so also cause producing the PDU state.With regard to can't give the data transaction of this buffering between this Node B of this Target cell or in the Node B with regard to the example of cell change, to transmit this PDU state in this a kind of mode be useful.
Though the present invention has been described in detail in detail, be understood that not limit the present invention to the there, and can not break away from claim to the present invention in defined marrow and the category in wherein doing all changes.
