Description
Technical field
The present invention relates to terminal and wireless (wireless) communication system that radio communication service is provided, and relate to the method for operation of PDCP (PDCP) entity in the universal mobile telecommunications system (UMTS), more particularly, relate to following this method of operation, promptly, send (a plurality of) data block by in data block, adding Connection Frame Number (CFN:connection frame number) by transmitter side (transmitter), make that receiver side (receiver) can be according to handling each data block that receives fiducial time, this method of operation provides circuit switching (CS) professional method as utilizing high speed downlink packet access (HSDPA) or high speed uplink packet to insert (HSUPA) technology.
Background technology
Fig. 1 shows the exemplary network structure of universal mobile telecommunications system (UMTS).The UMTS system generally includes terminal (that is subscriber equipment (UE)), UMTS wireless connections net (UMTS Terrestrial radio access network (UTRAN)) and core net (CN).UTRAN comprises one or more RNS (RNS), and each RNS comprises radio network controller (RNC) and by one or more base station (Node B) that RNC managed.Can have one or more sub-district among the eNode B.
Fig. 2 shows the exemplary configurations of the wireless protocols that is used for UMTS.These wireless protocols structure sheafs exist between terminal and UTRAN in couples, and handle the deal with data transmission by wave point.Introduce each radio protocol layer below.At first, physical layer (layer 1) is used various Radio Transmission Technologys, is sent data via wave point.Physical layer is connected to the upper strata that is called medium access control (MAC) layer via transmission channel.Whether share according to channel, transmission channel is divided into dedicated transmission channel and Common transport channel.
The second layer comprises various layers, such as MAC, RLC, PDCP and BMC layer.At first, medium access control (MAC) layer is carried out the mapping from various logical channels to various transmission channels, and multiplexing by several logic channels being mapped on the single transmission channel logical channels.The MAC layer is connected to the upper strata that is called Radio Link control (RLC) layer via logic channel.According to the type of the information that is sent, logic channel is divided into the control channel of the information that sends chain of command and the Traffic Channel of the information that sends user's face.According to the type of the transmission channel that will manage, the MAC layer can be divided into MAC-b sublayer, MAC-d sublayer, MAC-c/sh sublayer, MAC-hs sublayer and MAC-e sublayer.MAC-b sublayer management broadcast channel (BCH), this broadcast channel is the transmission channel of handling the broadcasting of system information.MAC-c/sh sublayer managing common transmission channel, such as forward access channel (FACH) or DSCH Downlink Shared Channel (DSCH), this Common transport channel is shared by a plurality of terminals.MAC-d sublayer management dedicated channel (DCH), this dedicated channel is the dedicated transmission channel that is used for particular terminal.In addition, up in order to support/the down high-speed data transmission, MAC-hs sublayer management high speed descending sharing channel (HS-DSCH), this high speed descending sharing channel is the transmission channel that is used for the high-speed down data transmission.MAC-e sublayer management enhancement type special channel (E-DCH), this enhancement type special channel is the transmission channel that is used for the high speed uplink transfer of data.
Radio Resource control (RLC) layer is used to guarantee each radio bearer (RB) and the desired various QoS of transfer of data (Quality of service, service quality).Each RB has one or two independently RLC entity, to guarantee unique QoS at each RB, and rlc layer provides three kinds of operational modes, promptly, TM (Transparent Mode, transparent mode), UM (Unacknowledged Mode, not affirmation mode) and AM (Acknowledged Mode, affirmation mode), to support various QoS.In addition, the data that rlc layer will receive from the upper strata carry out segmentation and/or series connection, to adjust data size, make lower floor these data can be sent to wave point suitably.
The PDCP layer is positioned on the rlc layer.The PDCP layer is carried out the header compression function that is used to reduce unnecessary control information, makes it possible to send the data that adopt Internet protocol (IP) grouping (such as IPv4 grouping or IPv6 grouping) and transmit efficiently via the less wave point of bandwidth.Therefore, header-compressed only sends necessary information by the header portion that allows data and improves efficiency of transmission between the wave point.Because header compression function is arranged in the PDCP layer basically, so the PCDP layer exists only in the PS territory.In single RB, there is single PDCP entity, to provide header compression function efficiently to each PS business.
Broadcast/group broadcast control (BMC) layer of layer 2 (L2) is positioned on the rlc layer.The BMC layer is dispatched Cell Broadcast CB (CB) message, and broadcasts this CB message to the terminal that is arranged in specific cell or a plurality of sub-districts.
Radio Resource control (RRC) layer that is arranged in layer 3 lowest part only is defined in chain of command.Rrc layer is used at the foundation of radio bearer (RB) (configuration), resets and discharge explicitly the parameter of layer 1 and layer 2 is controlled, and logic channel, transmission channel and physical channel are controlled.Here, logical path 2 that provided by the layer 1 of wireless protocols and layer, be used for transmitting data between portable terminal and UTRAN is provided RB.Usually, the foundation of RB is meant following process, that is, regulation provides the feature of required radio protocol layer of specific data service and channel, and corresponding detail parameters and method of operation are set.
Wideband Code Division Multiple Access (WCDMA) (WCDMA) system adopts high speed downlink packet to insert (HSDPA) and high speed uplink packet inserts (HUSPA) technology.Particularly, adopt these two kinds of technology to support packet switching (PS) business effectively.HSDPA and HSUPA are also referred to as HSPA.
Circuit switching (CS) scheme is by set up the scheme that telecommunication circuit is come swap data between transmitter side and receiver side.In the CS scheme, between two websites that expectation communicates each other, the private communication path is set in advance, and this private communication path comprises the link that is used for one after the other connecting each node.Each physical link is connected by individual channel, and therefore, each physical link can be suitably and easily is used in the exchanges data, and this needs seamless relatively stream, such as phone, transducer, remote measurement input etc.During transfer of data, the CS scheme is transmitted data via the telecommunication circuit of being set up.When therefore, this is suitable for sending larger data amount or longer message (for example, file transfer).The multiplexing, very efficient for high-quality high speed data transfer thus of digital switching technology in the digital telecommunication circuit and pulse code modulation adopted in time division circuit exchange.In this scheme, distributed special-purpose (fixing) physical circuit between each end points in two end points, make thus to minimize from time point to the transmission delay between the time point that begins transfer of data that generates data.In addition, because used special-purpose (fixing) circuit, so, in each data, there is not the reverse phenomenon of order of transmission (transmission order reversal phenomenon).
Packet switching (PS) scheme is the scheme that the data transmission unit that will have length-specific in the transmitter side packet switch is stored as packet format.The PS scheme is selected suitable communication path according to the address of receiver side, then, sends it to the receiver side packet switch.In the PS scheme, the data block unit (be called " grouping ") short according to length sends data.Usually, the length of grouping is restricted to about 1000 bytes.Each grouping is made up of the part of the control information that the part and the expression of expression user data are divided into groups.Here, the control information of grouping should be included in the needed information of the path that this grouping is set in the network at least, so that this grouping can be sent to receiver side.In case each node receives grouping via transmission channel, then at first store these groupings, send it to next node then.Continue this storing process, till transmitting the packet to receiver side, then, repeat transmission process to next node.In this scheme, particular terminal does not occupy specific passageways constantly, on the contrary, only occupies and use specific passageways in needs, makes the service efficiency of circuit maximize thus.In addition, can send each data cell by different paths, therefore, the transmission delay amount that each data experienced differs from one another.
Recently, developed multiple mobile communication business, so that support the maximizing efficiency of Packet Service (such as internet browsing etc.).In these mobile communication businesses, voice communication service is regarded as most important business in the mobile communication, and mainly provides voice communication service by circuit-switched service.
Current, the UMTS system has additionally adopted R5HSDPA and R6HSUPA to support the PS business based on the CS business having been carried out the R99 version WCDMA that optimizes.That is to say, the support of current system be used for the CS network of CS business and support the PS business the PS network the two.But, from the angle of network operation, the cost problem of CS network and PS network being installed and managing these two networks independently will appear.
In order to address this problem, the PS network is only runed in expectation, and reduces the support to the CS network step by step.For this reason, need a kind ofly to replace the method for whole CS business, perhaps a kind of method that the CS business is provided effectively in the PS network with the PS business.
Particularly, the method that needs a kind of CS speech business of support representative CS business in PS network (that is, having adopted the HSPD network of HSDPA and HSUPA technology).
Summary of the invention
Therefore, one object of the present invention is, provides a kind of in the PS network or be sent in the method for the data that generated in the CS business effectively in the wireless protocols of only supporting the PS business.

Embodiment
One aspect of the present invention is, by relevant above-mentioned problems of the prior art and the shortcoming that the inventor recognized, and will specifically introduce in the back.Based on this understanding, developed each feature of the present invention.
The present invention can be applicable to the 3GPP communication technology (particularly, UMTS system, communicator and communication means).But the present invention is not limited to the UMTS system, but can also be applied to can use in whole wire/wireless communications of technical scope of the present invention.
The present invention relates to a kind of method that data are provided conceptive in wireless way system, this method may further comprise the steps: receive at least one Service Data Unit SDU from the upper strata; Add header to described at least one the Service Data Unit SDU that receives, to generate protocol Data Unit PDU, wherein, described header comprises timing information; And the protocol Data Unit that is generated is sent to lower floor; And, the present invention relates to a kind of radio mobile communication terminal or the network that can realize this method.
As mentioned above, the invention provides a kind of in the PS network or in the wireless protocols of only supporting the PS business, be sent in the method for the data that generated in the CS business effectively.Particularly, the present invention proposes to send the CS business datum by comprising timing information to the CS business datum, remaining on the order (order) of the data that generated in the CS business, and solve during the CS business data transmission because the different problems that propagation delay time caused.
More particularly, if specific protocol entity receives Service Data Unit (SDU) from the CS service application, then this protocol entity is handled this SDU, and the SDU after will handling then (that is protocol Data Unit (PDU)) is sent to the protocol entity of below.Here, suggestion comprises the timing information about SDU or PDU in PDU.Here, this protocol entity can be PDCP (PDCP) entity, Radio Resource control (RRC) entity, Radio Link control (RLC) entity or medium access control MAC entity.In addition, this timing information can be a part or the information relevant with CFN of Connection Frame Number (CFN), CFN.The moment or CFN that this timing information can indicate SDU to generate perhaps can notify relevant information.The moment or CFN that this timing information can indicate PDU to generate perhaps can notify relevant information.In addition, this timing information can indicate transmitter side to receive the moment or the CFN of SDU from high level, perhaps notifies relevant information.This timing information can indicate the receiver side should treatment S DU or the moment or the CFN of PDU, perhaps notifies relevant information.In addition, this timing information can be indicated the moment or the CFN that is used to indicate transmitter side treatment S DU or PDU, perhaps can notify relevant information, perhaps can indicate receiver side to transmit SDU or the extremely high-rise moment or the CFN of PDU, perhaps can notify relevant information.In addition, the moment or CFN that this timing information can indicate transmitter side that SDU or PDU are encrypted, or during encrypting applied sequence number, perhaps can notify relevant information.This timing information can indicate receiver side to carry out the moment or the CFN that deciphers to SDU or PDU, perhaps needs the sequence number of application between the decryption period, perhaps notifies relevant information.In addition, this timing information can be the CS counter, and value that can this CS counter is set to 1LSB to the 5LSB of the CFN when high level receives grouping.
Below, introduce structure and operation with reference to the accompanying drawings according to preferred implementation of the present invention.
At first, introduce the Connection Frame Number (CFN) relevant with the present invention.CFN is by being in the timing information that base station in the RRC connection status and terminal are managed.CFN is unique setting in each terminal, and can be that data generate constantly or data processing benchmark constantly.CFN can be an employed sequence number value when in the MAC entity MAC SDU being encrypted or deciphering.In addition, CFN increases along with the increase of time.For example, suppose that CFN was 0 in the time of 0.000 second, then CFN CFN in the time of 0.020 second becomes 1, becomes 2 in the time of 0.040 second.Through special time period each constantly, CFN increases, and with whether send data independence at particular point in time.In this case, CFN is when having passed through special time period and the value that increases, and with whether reality sends or receive data independence.The CFN field is expressed as follows this CFN: at this CFN place, TM RLC PDU is handled by MAC, and this CFN be used for sending entity encrypt and be used for receiving entity be decrypted and to sequence go the shake (de-jittering).
This CFN information representation timing information, such as, the time point, particular data that generates particular data from the top entity arrive special entity time point, particular data is sent to the time point of below entity, particular data is sent to the time point of top entity or handles the time point etc. of particular data.CFN is used for time point information that the operation that sending entity and receiving entity should be carried out in particular moment is defined.
Fig. 4 shows the CS service application in the exemplary plot that inserts the method for (HSPA) technology based on high-speed packet.As shown in Figure 4, the MAC entity uses the information relevant with CFN according to the present invention.That is to say that compared with prior art, the present invention uses the RLC TM pattern of CS scheme in the HSPA technology, and comprises the information relevant with CFN in the mac header of MAC block.
Usually, when terminal (or UE) when non-HSPA sub-district moves to the HSPA sub-district, if the CS user face data is mapped to RLC UM, then need the reconfiguring of radio bearer from RLC TM to RLC UM.Here, can use RB release and RB to set up message and finish reconfiguring of RB.RNC needs to wait for, up to receive radio bearer set up finish (RadioBearer Setup Complete) message till, with the STRAT value that obtains to be used to encrypt.In the present invention, suggestion is mapped to RLC TM with the CS user face data, rather than RLC UM.Therefore, do not need by carrying out the RLC mode switch such as the process that RB discharges and RB sets up.RRC can reconfigure transmission channel kinds, rather than conversion RLC pattern.In this way, can shorten process from non-HSPA sub-district to the switching of HSPA sub-district.Because use same time reference, so this also makes it possible to carry out bumpless transfer between DCH and HSPA.
By in the MAC TM header that is mapped to HSPA (MAC-hs, MAC-ehs or E-DCH), comprising CFN or the information relevant, can in the MAC entity, finish encrypt/decrypt at the CS U face data of RLC TM with CFN.This can also eliminate when using RLC UM pattern because packet loss (perhaps, in particular for undetected mistake) causes, any possible encryption asynchronous (de-synchronization) problem (this former be found).
Fig. 5 shows the exemplary plot of the data block that is generated in medium access control (MAC) entity.More particularly, Fig. 5 PDU of showing in MAC-d to be generated.MAC-PDU can be made up of mac header and Medium Access Control (MAC) Service Data Unit (MAC SDU), and MACSDU can have variable-sized.The size of MAC SDU can depend on the size of RLC PDU, and the size of RLC PDU defines in setting up process.
CFN shown in Fig. 5 can indicate the value of the CFN when generating MAC-d PDU, and can be used for the dithering process of going of receiver side.Here, the shake phenomenon that is meant when each data block that will generate continuously according to the even time interval is sent to receiver side, arrives at interval less than the initial rise time according to each data block.In order to address this problem, receiver side rearranges the data block that receives, and one by one the data block after resetting is handled according to particular time interval then.In the present invention, suggestion is in going dither process, receiver side should be according to the order of CFN (promptly, CFN information) (order of CFN is based on the timing information that is included among the PDU that receives) reset the PDU that receives, then, based on the value of CFN, come PDU or the SDU that is included among the PDU are handled according to particular time interval, here, de-jitter buffer can be used for dithering process.In above-mentioned processing, only the part except CFN is encrypted or deciphered.But in this was handled, it may be a kind of waste that CFN is included in whole MAC blocks.For example, speech data is to generate according to every 20ms, if CFN is 12 bits, then this will cover and 81 seconds time corresponding.So Chang CFN has caused the waste of wave point, and therefore, in above processing, the present invention can include only the bit than lower part among the CFN at MAC block.
According to the characteristic of AMR codec (codec), the present invention also supports son stream.The codec that 3GPP will be called " AMR " is used for the CS speech business.In the AMR codec, the data rate of the codec that use changes changeably according to wireless environment.Particularly, in the AMR codec, generate 3 data flow A, B and C.Because each data size difference that is generated in each height stream, so transmitter side should be notified to receiver side effectively with the data volume that is generated in each height stream.
Therefore, the present invention's suggestion comprises the designator that is called " son stream combined index " in the PDU that is generated.This is the value that is set in advance by terminal and base station, and is used in reference to the quantity of each bit of A stream, B stream and C stream in the PDU that is shown in current generation.For example, son stream combined index shown in Figure 6 can be applied to the present invention.That is to say that when generating PDU, transmitter side checks that to the data volume that is included in each the height stream among each PDU search is suitable for the combined indexes of this data volume, then, sends this PDU among the PDU by this index is included at every turn.Receiver side checks the son stream combined index that is included among the PDU that receives, and extracts and flow the bit of corresponding quantity from each height of PDU according to the indication of this index, thereby sends each height stream to.
As another kind of method, there is not following this index in the combination according to the bit number of son stream current definition and permission in AMR, every, and is identical with the summation of the corresponding data of each height stream in each combination in this index.Therefore, if used index and the size of the PDU that receives, then can know with PDU in corresponding respective index and the data volume of each height stream.Therefore, the present invention advises that receiver side should extract the bit of pre-specified amount according to the size of the PDU that receives, from PDU, and the bit that is extracted is sent to each height stream.In this case, DPCP PDU can include only data, and does not comprise header.Fig. 7 show according to of the present invention, in the exemplary plot of the form that a plurality of sub-streams is carried out the PDU when multiplexing.Here, finish a plurality of sub flow multiplexing by the PDCP entity.
Fig. 8 shows the exemplary plot according to the structure of PDCP (PDCP) sublayer of son stream of the present invention, as to be used for the CS territory.If the PDCP among Fig. 8 is used to transmit the CS voice, then on all directions, PDCP is mapped to 3 TM and carries.Fig. 8 shows by the PDCP entity and finishes the multiplexing situation that each height is flowed.Here, when the CS business be linked into via the PDCP entity wireless technology based on PS (such as, HSDPA or HSUPA) time, use multiplexing.
Each CS territory RAB is associated with a PDCP entity.The PDCP entity is associated with a plurality of RLC fluxion amount, that have transparent mode corresponding to RAB.Provide the PDCP entity of CS business not use header-compressed.
The effect that the present invention has is, by following this method of operation, promptly, when utilizing high speed downlink packet access (HSDPA) or high speed uplink packet access (HSUPA) technology to provide circuit switching (CS) professional, send the Connection Frame Number that is included in the data block by transmitter side, make receiver side to support the CS business in the HSPA network efficiently according to handling each data block that receives fiducial time.
