Abstract
The present invention relates to a system and a method which facilitate high speed-downlink shared channel (HS-DSCH) cell change. The present invention discloses a method and system for the UE to perform a serial of actions in order to reduce the latency and potentially prevent loss of PDU transmission during the serving HS-DSCH cell change procedure. A new criterion is introduced for UE generation of the status report of RLC PDU. The UE generates status report of the PDUs as soon as possible following notification of the HS-DSCH cell change indicated by the RRC procedure to more efficiently recover source Node B buffered data. PDU status may be signaled for each AM RLC instance associated with the HS-DSCH transport channel. Furthermore, upon Inter Node B serving HS-DSCH cell change the SRNC may wait for PDU status report before initiating transmission of new data in target cell.
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 after in the wireless system of intermediate point distribute data, switching, effectively recover buffered data.Comprise the remote network control device (RNC) that is coupled on one or more Node B and utilize adaptive modulation and coding (AMC) and mix the third generation (3G) system automatically heavily send request (H-ARQ) technology (wherein said one or more Node B again successively wireless type be coupled on a plurality of subscriber equipmenies (UE)) 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 residential quarter 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, therefore the data buffering that must will transmit is in Node B.This structure causes this RNC not obtain the last state of its control packet data residential quarter (PDU) transmission of this Node B.Therefore, in case when switching in the minizone, then must coordinate with regard to this cell change the scheduling of described transfer of data.Not so, then must be behind this cell change, " leakage " or " repeats transmission to make the transfer of data re-synchronization, with the data of avoiding transmitting ".In 3G network, the switching of minizone is by this RNC control.Because the RNC that is used for controlling the residential quarter that comprises this UE can change, therefore 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 residential quarter is greater therefore 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 successfully transmitting data.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 replacing sense of community and improve to physical channel condition and/or entity capacity, then cause this service HS-SDCH cell change.Be different from other channel in the 3G network, this HS-DSCH interrupts in Node B interruption 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, it then is the service HS-DSCH cell change in the Node B.When this UE changes two minizones that are associated with different nodes B, it then is 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 and automatically heavily send request (ARQ) function as the transmission of data.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 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 identified 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 termly status report.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.Although the transmission that this H-ARQ operation meeting is failed with some removes and improves the probability of successfully transmitting data, 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 rapidly, with the maintenance service quality.During this service HS-DSCH cell change, this UE might stop this and come transmission in the cell-of-origin and reception until when transferring all and being stored at present PDU in this source node B.Because 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), therefore (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 the HS-DSCH cell change is provided, then because failing to give notice this RNC " data transmission scheduling of Node B " therefore how many data loss this RNC does not know to have fall (if some words), and this RNC does not also know whether this UE has and successfully recovers to confirm this transmission.Therefore 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 better modes to recover buffered data on this source node B.Namely 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 situation, with request PDU state clearly, this RNC must wait until first in this new residential quarter and set up till this physical channel this RNC by this UE of poll.Then, this RNC transmits this PDU status request, and this UE receives and process this request.This UE produces this PDU state, and this PDU state is returned to this RNC, and wherein this RNC processes this PDU state and determines which PDU needs again transmission.
In this second 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 processes this PDU state and learns which PDU needs again transmission.
In above-mentioned two situations any when recovering buffered data in this source node B such as need, then can remove to process 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 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 until can transmit data in proper order the time, just send data to higher level.In this way, can require this UE to cushion these not sequenced data until can again transmit the PDU of described omission the time.This has not only incured loss through delay this transmission, also requires simultaneously this UE to have internal memory even as big as buffered data until can successfully transmit the data that are stored in this source node B.Otherwise this effective speed can reduce, thereby affects service quality.Because internal memory is very expensive, so for designing improperly restrictive condition.
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, first 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
The present invention a kind ofly carries out a succession of action so that shorten the described stand-by period during this service HS-DSCH cell change program and prevent that potentially PDU from the method and system of leakage occuring when transmission.Introduce new criterion and produce this RLC PDU status report for UE.After having notified this indicated HS-DSCH cell change of this RRC program, this UE just autonomously produces this PDU status report as early as possible, more effectively to recover the buffered data of source node B.Can be (AM) RLC example (instance) of each affirmation pattern that is associated with this HS-DSCH transfer channel and send the PDU state with signal.

Fig. 2 waits until the PDU state, just begins to transmit the flow chart of the another kind of method of a new data in this Target cell for this RNC.
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, therefore after having notified this indicated HS-DSCH cell change of this RRC program, this UE just autonomously sends described PDU state to this RNC.The PDU state of this generation can be used for each AM RLC example of being 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 without any disadvantageous consequence.
When in case this UE has received this RRC request message (step 18), this UE namely 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 do not transmit in order data).
This UE can carry out many different alternative methods, produces the PDU status report to cause behind service HS-DSCH cell change.Yet in this several embodiment are proposed.Preferably, select such as first, in case when having removed the buffering area of this high speed medium access control (MAC-hs) its rearrangement, 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 send in order to trigger wish the RLC PDU status message of this RNC to from this UE.Since this program, produce in the short period of time this PDU state 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.How the method for this PDU state of described transmission can send the embodiment (non-pre-requisite of the present invention) of this PDU state with signal to this RNC for this UE, wherein be explanation in case when new criterion is arranged, namely 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, namely 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 ".Such 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, identify this PDU state.Then, this RNC RRC entity notify this RLC " state of described PDU ", to continue again to be transferred to this target node b.
In the 3rd selected, this UE sent the status report of L3 signaling message new on this relevant DCCH 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 again to be transferred to this target node b.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 described last in proper order success transmission; 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), wherein this highest sequence number SN of the 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 processed 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, therefore can force this UE RLC to cushion these data, make data can pass in proper order higher level.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 until successfully transmitted the in proper order data of 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, and wherein this RNC stops all down link HS-DSCH that lead to this UE and waits upon defeated until processed this PDU status message (step 24).The time that this specific embodiment postpones when making the buffered data that again transmits source node B 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 for basic take first in first out (FIFO).Therefore, the RNC such as this Target cell when just passing on data before this PDU state is processed, then can transmit first this data.The data of this formation in Node B might make the required time of the buffered data that again transmits this source node B 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 in 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 in cell change and the Node B between a Node B, therefore also cause producing the PDU state between Node B with Node B in two kinds of examples.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.
Although 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.
