Description

Data Receiving, sending method and Data Receiving, dispensing device

Technical field

The present invention relates to the technical field that Data Receiving and data send in the mobile communication, the data transmission method for uplink and the data sending device of particularly data receive method and the data sink of UE under cell forward access channel (CELL FACH) state, and this moment network side.

Background technology

Third generation partner program (3GPP) system is divided into subscriber equipment (User Equipment, UE), universal mobile telecommunications system grounding wireless access network network (UMTS Terrestrial Radio AccessNetwork, UTRAN) and core net (Core Network, CN) these three parts.The interface of UE and UTRAN is the Uu interface, is mainly used in the function that wireless access subscriber is provided.The protocol stack of Uu interface comprise Radio Resource control (Radio Resource Control, RRC), unlimited controlling links (Radio LinkControl, RLC), the medium access control (Medium Access Control, MAC) and agreement such as physical layer.The RRC agreement provides the signaling plane of Uu interface to connect, and is used for control channel between UTRAN and UE.When between UE is with UTRAN, having the RRC signaling to connect, be called UE and be in the RRC connection mode, UE will be in a kind of in 4 kinds of RRC states this moment, and these 4 kinds of RRC states are respectively UTRAN Registration Area paging channel (URA_PCH), cell _ paging channel (CELL_PCH), cell forward access channel (CELL_FACH), CELL _ DCH (CELL_DCH).These 4 kinds of states can be changed, and the situation of various conversions as shown in Figure 1.

When UE is in different RRC connection status, have different processing modes, specifically describe as follows:

When UE was in the CELL_DCH state: UE had Dedicated Control Channel (DCCH) and Dedicated Traffic Channel (DTCH), and utilized dedicated channel or shared channel to transmit the state of communication process; This dedicated channel is can only be by the Radio Resource of this UE use.

When UE was in the CELL_FACH state: UE had DCCH or has DTCH simultaneously, can on FACH, receive signaling or data, and, need not assigned with dedicated channel in last signaling or the data of sending of Random Access Channel (RACH), on public FACH/RACH channel, transmit condition of information; Owing to do not take dedicated channel, so can save Radio Resource, need not send the reception dedicated channel continuously simultaneously, UE also can power saving.

When UE was in the CELL_PCH state: UE can not use DCCH and DTCH, cannot receive and send data, state that can only be when the paging indicating message on the down direction listening paging indicating channel (PICH); Can only send cell update (CELL Update) message and give radio network controller (RNC); In the conversion of sub-district to the RNC register information; Because PICH is discontinuous monitoring, compare in the power saving more of CELL_FACH state so be in the UE of this state.

When UE was in the URA_PCH state: UE can not use DCCH and DTCH, cannot receive and send data, only the state when down direction is intercepted paging indicating message on the PICH channel; Can only send URA renewal (URA Update) or Cell Update message and give RNC; In the UTRAN Registration Area conversion, register to RNC; Because the scope of UTRAN Registration Area is more much bigger than the sub-district, so the UE that is in this state is than CELL_PCH power saving more.

When needs allowed the UE that is in CELL_PCH and URA_PCH state send or receive data, needing earlier the state exchange with this UE was CELL_FACH or CELL_DCH.This state exchange can be to be initiated by network, also can be initiated by UE.

In 3GPP, transmission channel is mapped on the physical channel and transmits.The data of transmission channel are with transport block set (Transport Block Set, TBS) be data unit, with a Transmission Time Interval (Transmission Timing Interval, TTI) be chronomere, transmit on the physical channel that to be mapped to 1 10ms frame be unit.Wherein, TBS is polymerized by a plurality of transmission blocks (TB).

Be with Connection Frame Number (Connection Frame Number on the transmission channel, CFN) be numbered and count, be mainly used in the transport channel synchronization between UE and the UTRAN, for example the given transmission channel activates use or uses new transmission parameter etc. on certain CFN, and CFN is unit with 10ms.For the PCH channel, the numbering space of its CFN is 0 to 4095; And for other transmission channels, the numbering space of its CFN is 0 to 255.

Be that (Cell System Frame Number SFN) is numbered and counts, and each frame all can be transferred to UE by UTRAN on broadcast channel with Cell System Frame Number on the physical channel.The numbering space of SFN is 0 to 4095.

CFN does not aloft transmit on the interface.But UE and UTRAN both sides can calculate CFN from SFN by the corresponding relation of CFN and SFN.

Downlink common transport channel FACH be mapped to time Common Control Physical Channel (SecondaryCommon Control Physical Channel, S-CCPCH) on.The TTI of FACH is generally 20ms or 40ms.So, the transmission of a FACH data TBS needs the physical channel frame of two continuous SFN just can be transferred to UE.FACH is shared by all UE in the whole sub-district, and the scheduling of transfer of data is to carry out at RNC between the UE.Definite UE and the data thereof that will on FACH, transmit of RNC, just TBS, UE sign (ID) and CFN number of will transmit are sent to Node B, carry out the processing of TBS by Node B, this processing comprises cyclic redundancy code (CRC) verification, chnnel coding, interweave etc., is mapped at last that the modulation spread spectrum sends on the physical frame of several S-CCPCH.Wherein, the number of the physical frame of S-CCPCH is by the decision of the length of TTI, equals TTI divided by 10ms, and for example TTI equals 20ms, and then the number of physical frame is exactly 2.After UE receives the S-CCPCH frame, the physical frame of each 10ms of demodulation of elder generation according to the TTI of FACH, carries out deinterleaving, decoding etc. with several physical frames in the TTI more altogether, obtain TBS at last, and determine by CRC check whether each TB among the TBS transmits correctly.

Because FACH is a common signal channel, UE need judge whether the FACH data that receive are to one's name.The TBS that the FACH data of a TTI are made up of a plurality of TB transmits, and each TB is a mac frame, comprising the mac frame head.At RNC, shining upon logic channel on the FACH channel, comprise and be used for Dedicated Control Channel (the Dedicated Control Channel of command transmitting, DCCH), be used for transmitting Dedicated Traffic Channel (the Dedicated Traffic Channel of data, DTCH) and be used for transmitting public control channel (the Common Control Channel of public control signaling, CCCH), the mac frame head has a territory to indicate this TB to belong to which kind of logic channel.If Dedicated Control Channel and Dedicated Traffic Channel are mapped on the FACH, then include the sign of UE in the mac frame head, UE can judge from this UE sign whether to one's name this TB like this.

For power saving, will there be the UE of data interaction to be transformed into CELL_PCH or URA_PCH state usually for a long time.In existing 3GPP agreement, when UE is under CELL_PCH or the URA_PCH state, if when sending upstream data and need send downlink data to UE to network or network, need earlier by Cell Update process with the RRC state exchange under CELL_FACH or CELL_DCH, just to activate UE earlier.Its signaling process may further comprise the steps as shown in Figure 2:

Step 101, when UE is under the CELL_PCH state, network will send data or signaling to UE, needs first paging UE, and then RNC sends the 1st class beep-page message to UE.

Step 102 after UE receives beep-page message, need send CELL Update message to RNC, and CELL_FACH is arrived in the state transition of oneself.

Another kind of situation is that UE is in the CELL_PCH state and will sends upstream data, then needs to send CELL Update message, earlier CELL_FACH is arrived in the state transition of oneself.In this case, owing to be that UE initiatively will send data or signaling, just do not need the paging of execution in step 101.

Step 103, UE is being mapped to transmission cell update message on the CCCH of RACH, and it is former because " transmission upstream data " or " paging reply " that this message is carried cell update.

Step 104 after RNC receives this message, according to the cell update reason, need be retained in the state of UE CELL_FACH or moves on the CELL_DCH, and UE just can transmit and receive data like this.So still move to the CELL_DCH state to being retained in CELL_FACH, need decide according to RRM (RRM) algorithm.The algorithm that has is in this case, earlier with the state exchange of UE to CELL_FACH, after adjust according to the data traffic of UE again, if flow is big, then adjust to CELL_DCH; The algorithm that has is that the operating position of present private resource of basis and public resource decides.

Step 105, the RNC decision is after being retained in CELL_FACH or moving to CELL_DCH, sends the cell update acknowledgement message, and RRC state information and other configuration informations are sent to UE.

Step 106, after UE received the cell update acknowledgement message, the RRC state according to the RRC state configuration oneself of RNC indication sent the mobile message acknowledge message simultaneously and replys.Here except the mobile message acknowledge message, also may be other message, for example wireless channel reconfiguration message etc.

Step 107, cell update flow process finish, UE can with network interaction data and signaling.

Calculate the time delay of said process below.Beep-page message need send at the calling time of this UE, and calling time is general at interval about 600ms, and so average each beep-page message need wait 300ms, needs if beep-page message takes defeat to retransmit, and also will wait 600ms.CELL Update, Cell UpdateConfirm, mobile message acknowledge message or other message authentication message, probably the needing about 300ms alternately of this 3 message.So the above-mentioned time is added up, the time delay of whole process needs 600ms at least.

From as can be seen above-mentioned,, change UE over to CELL_PCH or URA_PCH state for power saving.But when needing transceive data, need carry out the conversion of state by cell updating course, can transceive data.And the time delay of this process is very long.If a user's the less data that often has will pass, need constantly carry out state exchange, promptly forward to and forward CELL_PCH/URA_PCH again to after CELL_FACH/CELL_DCH sends data, the time delay of data transmission is very big like this, has reduced user's business experience.For example in the intercom business, both sides do not speak for a long time, are changed over to the CELL_PCH state, as long as but loquitur, need wait for a long time and can hear and reply.And there is a lot of cell update signalings to transmit in the interface aloft, thereby caused the waste of idle wireless resource simultaneously, also reduced the performance of system.

In order to solve above-mentioned prior art problems, in realization, UE can be placed under CELL_FACH or the CELL_DCH always.If but under CELL_DCH, will need the configure dedicated channel to give this UE, and the quantity of dedicated channel is limited.If a UE does not have data to send for a long time, and is under the CELL_DCH, will cause the significant wastage of resource, reduced the capacity of the access UE of system.Simultaneously, UE needs to send continuously and receive dedicated channel, causes battery consumption very big, has also reduced customer service experience.

For the shortcoming of the waste of radio resources that solves technique scheme, in realization, UE that can data traffic is very little changes the CELL_FACH state over to.UE does not in this state have dedicated channel, all data and signaling all be on up FACH and descending RACH, to receive and dispatch.In the time of data transmit-receive, just utilize common signal channel, when not having data transmit-receive, common signal channel uses just can for other UE, so just can not cause waste of radio resources.But UE need receive the TBS of all TTI on the FACH channel continuously, and the mac frame head that needs to resolve all TB on the TBS judges whether this TB is to one's name.If the data volume of UE is very little, and UE needs all data on continuous reception and the parsing FACH, and the battery consumption to UE is also very big like this, has caused the waste of battery.

Further,, proposed UE carries out discontinuous reception to S-CCPCH under CELL_FACH method recently, might as well be referred to as the discontinuous receiving state of CELL_FACH in order to solve the bigger shortcoming of battery consumption in this technical scheme.But, in the method, need to send when UTRAN has more data, and UE can only receive, and will cause the transmission delay of UTRAN very big on the discontinuous frame of some appointment.Simultaneously, if UE has sent the data of affirmation mode (AM) RLC, UTRAN receives mistake, need to send the NACK message request and retransmits, and then needs to wait for the arrival of the discontinuous frame of appointment, has increased the time delay of RLC data re-transmission.

Summary of the invention

In view of this, the present invention proposes the data receive method of a kind of UE under the CELL_FACH state, in order to reduce the time delay of transfer of data.Another object of the present invention is to propose the data sink of a kind of UE under the CELL_FACH state.A further object of the present invention is to propose the data transmission method for uplink of a kind of UE in CELL_FACH state lower network side.Another purpose of the present invention is to propose the data sending device of a kind of UE in CELL_FACH state lower network side.

Embodiment

For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in more detail by the following examples.

The technical essential of the embodiment of the invention is to be under the CELL_FACH state as UE, according to certain pattern, with the discontinuous data that receive continuously and resolve on the wireless channel of being mixed with.In the following description, noun " data " refers to all information of transmitting on wireless channel, comprises signaling, state information of business datum, each protocol layer etc.Simultaneously, RNC is according to identical pattern, and discontinuous being mixed with sends downlink data continuously to UE on wireless channel.Described pattern can be to be stipulated by agreement in advance, also can be to give UE according to data traffic and other policy configurations of UE by UTRAN, and also can be that UE oneself dynamically adjusts.Discontinuous reception modes can be that the CFN according to transmission channel is provided with, also can be provided with according to the SFN of physical channel, perhaps the TTI according to transmission channel is provided with, perhaps the sign according to UE is provided with, the sign of described UE such as international mobile subscriber identifier (International Mobile Subscriber Identity, IMSI), UTRAN Radio Network Temporary Identifier symbol (UTRAN-Radio Network Temporary Identifier, U-RNTI), Cell Radio Network Temporary Identifier/Identity, Cell-RNTI symbol (Cell RNTI, C-RNTI) etc.Wireless channel described here comprises that descending transmission channel FACH, DSCH Downlink Shared Channel (DSCH) or other are applied to the descending transmission channel of CELL_FACH, and down physical channel, comprise that S-CCPCH, PDSCH or other are applied to the down physical channel of CELL_FACH.

The setting and the determination methods of discontinuous reception modes are described below.The setting of discontinuous reception modes, be that UE carries out discontinuous reception modes under CELL_FACH scope is set, can be to be provided with that UE is under the discontinuous reception modes and the frame number that belongs to this UE, UE also can be set not need the frame number that receives, the frame number that belongs to this UE with setting is the example explanation in the following description, but the present invention is not limited thereto.Determination methods is meant whether the frame number of judging on the wireless channel belongs to the scope that is provided with of discontinuous reception modes.

Method one: utilize the CFN of transmission channel to be provided with and judge.

When adopting CFN to be provided with, multiple method to set up can be arranged.A cycle period P, continuous frame number N, side-play amount S for example are set.UE makes a decision with CFN so, and P equals S from the CFN mould, and the N continuous frame all belongs to the scope that is provided with of discontinuous reception modes.Wherein, P, N, S are positive integer, and P and N can not be greater than maximum frame numbers 255, and N<P, if N=P has received continuously.

Also for example, the mode with dot matrix is provided with.Because the numbering space of CFN is 0~255.The pattern of discontinuous reception, can be to specify CFN number of concrete reception, for example be provided with x1, x2, x3 ..., xn frame be this received frame, then UE judges whether current CFN belongs to the TTI under the CFN of appointment, is just to show that current CFN belongs to the scope that is provided with of discontinuous reception modes.Wherein, x1, x2, x3 ..., xn is integer.

Except above-mentioned example, also have other a lot of methods, the present invention is not limited to above-mentioned concrete grammar.

Method two: utilize the SFN of physical channel to be provided with and judge.

Use this set method, its concrete setting is identical with above-mentioned method one with determination methods, and the CFN above just replacing with SFN in the method one can use periodic mode, dot matrix way etc. equally.Only, because the numbering space of SFN is 0~4095, the reception of UE at interval can be bigger, more flexible.

Method three: utilize the TTI of FACH to be provided with and judge.

Because the TTI of FACH is the integral multiple of 10ms, we define a positive integer M and equal TTI divided by 10ms so.If TTI equals 20ms, M equals 2 so; TTI equals 40ms, and M equals 4, by that analogy.Can be provided with so when frame number (can be the CFN of transmission channel, also can be the SFN of physical channel) belongs to X and remainder and belongs to Y divided by the merchant of M, then this frame belongs to the scope that is provided with of discontinuous reception modes.Wherein, X and Y set in advance, X be a positive integer set x1, x2 ... xn}, Y also be a positive integer set y1, y2 ... yn}.

Method four: utilize the sign of UE to be provided with and judge.

The UE that is under the CELL_FACH has a lot of signs, comprises IMSI, U-RNTI, C-RNTI etc., is that example is described here with U-RNTI, but is to use other sign can realize the embodiment of the invention equally.The positive integer parameter set D that a discontinuous reception is set in UE for d1, d2 ... dn} if U-RNTI belongs to parameter set D divided by the merchant of frame number, shows that then this frame number belongs to the scope that is provided with of discontinuous reception modes.

The setting of other discontinuous reception modes and the determination methods of determination methods and UE are not given unnecessary details here one by one in addition, and embodiments of the invention are not limited to said method.

The setting and the determination methods of UE discontinuous reception modes under the CELL_FACH that has described above, then, the scope that is provided with of describing discontinuous reception modes is how to be configured to UE and UTRAN.

Specifically can adopt following method: in UE or network side RNC, carry out program compilation according to prior agreement and become fixing pattern, and be stored in the program storage of UE or RNC; UTRAN obtains configuration by the order of obtaining Configuration Manager; UTRAN calculates in real time by algorithm; Mode by the UTRAN notice is configured to UE with non-receiving mode; UE or network equipment receive outside configuration order, for example input of man-machine interface, IP network download etc., and resolve this configuration order, obtain the setting of receiving mode; Mode by the UE notice is configured to UTRAN with non-receiving mode.By said method, UE and network equipment are obtained the setting of receiving mode, and are applied to discontinuous reception judgement.

Implement algorithm computation with UTRAN below and notify the mode of UE to carry out the example that is set to of discontinuous reception modes, propose an embodiment.

UTRAN makes a strategic decision by the flow of UE, channel parameters such as load on the wireless channel or is made a strategic decision by the configuration input in the external world, determines the scope that is provided with of the discontinuous reception modes of UE, and discontinuous reception modes is provided with range notification to UE.Can be by RRC means of signaling notice, described RRC signaling method comprises that radio bearer configuration, radio bearer are reshuffled, transmission channel is reshuffled, RRC connects foundation or other message, also can notify by the special frames of RLC or MAC layer.UE receives the configuration information of the discontinuous reception modes that RNC sends over, and parses the scope that is provided with of discontinuous reception modes, is used for discontinuous reception and judges.The collocation method that it should be noted that the embodiment of the invention is not limited thereto.

The data receive method of discontinuous reception in the embodiment of the invention is described below.

The key of the embodiment of the invention is the data on the discontinuous reception wireless channel of UE that is under the CELL_FACH.On specific implementation, a variety of implementation methods is arranged.Two kinds are provided in the embodiment of the invention as example, a kind of non-continuous data method of reseptance that is based on state; Another kind is based on the non-continuous data method of reseptance of condition judgment.Simultaneously, the embodiment of the invention data sink of these two kinds of methods of realization that also proposes to know clearly.But the embodiment of the invention is not limited to this two kinds of method and apparatus.

Data receive method based on the discontinuous reception of state is described below.

In the present embodiment, be in the current state that UE under the CELL_FACH state has accepting state and non-accepting state.When being in accepting state, UE receives and deal with data; When being in non-accepting state, UE stops to receive data.

As shown in Figure 3, when UE is under the CELL_FACH state, have two states, a kind of is accepting state, and another kind is non-accepting state.When being in accepting state, UE receives the data on the wireless channel; When being in non-accepting state, UE stops to receive the data on the wireless channel.UE receives data, and can be to receive the physical channel frame, or receive transport channel data at the MAC layer in physical layer, or other forms of reception; UE stops to receive data, can be that physical layer stops to receive physical frame, or the MAC layer stops to receive transmission channel frame, or other forms of stopping to receive.

The conversion of accepting state and non-accepting state is driven by condition.For example, when accepting state,, then be transformed into non-accepting state if satisfy switch condition B; When non-accepting state,, then be transformed into accepting state if satisfy switch condition A.

In addition, when UE is initialized, can be in accepting state, also can be in non-accepting state, not influence the realization of the embodiment of the invention.

The above-mentioned switch condition A that is transformed into accepting state by non-accepting state comprises following several condition:

1) if belonging to the reception frame number of the scope that is provided with of discontinuous reception modes arrives, then condition A sets up, and wherein the setting of discontinuous reception modes as previously mentioned.

2) if UE has sent data that need UTRAN to reply, and this replys also and does not receive, then condition A sets up;

3) otherwise condition A be false.

The above-mentioned switch condition B that is transformed into non-accepting state by accepting state comprises following several condition:

1) if above-mentioned condition A be false, and the current Data Receiving that receives and resolve correctly, and these data do not belong to this UE, then condition B sets up;

2) otherwise condition B be false.

As shown in Figure 4 be to realize the above-mentioned non-continuous data receiving system that receives based on state.With reference to Fig. 4, the non-continuous data receiving system comprises status register, the data receiving processor that receives determining device, storage UE current state.Can further include receiving mode according to the condition of state exchange device, data transmitter etc. are set.

Wherein, receiving mode is provided with device discontinuous reception modes is input in the reception determining device, it can be by the discontinuous reception modes that the information that man-machine interface obtains is raised the price, the RNC configuration information is decoded, the protocol procedure compiling obtains that this receiving mode is provided with device, receives determining device then and utilizes it to carry out the judgement of state exchange.

Whether data transmitter will send the data that need reply, the information that whether needs to wait for data re-transmission is input in the reception determining device, utilize it to carry out the judgement of state exchange and receive determining device.

Receive determining device and in the judgement of carrying out state exchange, need from status register, obtain current state, promptly from status register, obtain the input of current state; Behind transition status, the state that upgrades need be outputed in the status register, to substitute oldState wherein.

Data receiving processor with the current data that receive whether receive parsing correctly and the information that whether belongs to this UE be input to and receive in the determining device, utilize it to carry out the judgement of state exchange and receive determining device.

Data receiving processor obtains current state from status register, be used to judge whether to receive operation, and carries out the Data Receiving operation under the situation that is.

Discontinuous receiving method based on condition judgment is described below.

UE judges whether present frame belongs to the frame that receive, if then receive, otherwise do not receive.The embodiment of the invention has proposed simultaneously to judge whether present frame is the method for this received frame.Specific implementation, the embodiment of the invention provide two kinds of following examples, a kind of discontinuous reception that is based on transmission channel, a kind of discontinuous reception that is based on physical channel.Transmission channel is that example is described explanation with FACH, and physical channel is that example is described explanation with the S-CCPCH channel.Obviously the present invention is not limited to this two kinds of channels.

Fig. 5 represents the discontinuous receiving method based on transmission channel.With reference to Fig. 5, the discontinuous receiving method based on transmission channel that is in the UE under the CELL_FACH state is as follows:

Step 201, UE receives the physical channel frame continuously.
