The present invention relates to communication technical field, more particularly to a kind of Τ switching methods, base station and user equipment.Background technology

With developing rapidly for the communication technology, WCDMA (Wideband Code Division Multiple

Access, WCDMA）One of mainstream technology as 3-G (Generation Three mobile communication system), has obtained extensive research and application in the world.In 3GPP (3rd Generation Partnership Project, third generation Partnership Program）DCH channels, referred to as R99 DCH, the covering that R99 DCH channels have had are introduced in the Rel-99 versions of formulation, but less data rate can only be improved.HSUPA (High-Speed Uplink Packet Access are introduced in the 3GPP Rel-6 versions formulated, High Speed Uplink Packet access) technology, introduced transmission channel is E-DCH (Enhanced Dedicated Channel, up enhancing in HSUPA）.E-DCH includes two kinds of transmission intercals（Transmission Time Interval, TTI) type, 2ms TTI and 10ms TTI, wherein 2ms TTI can provide high message transmission rate and small propagation delay time；10ms Τ can provide more preferable covering.Therefore user equipment is worked as（User Equipment, UE) from center of housing estate be moved to cell edge when in order to obtain more preferable covering, it is necessary to be switched to 10ms TTI from 2ms Τ;Accordingly, when UE is moved to center of housing estate from cell edge, in order to obtain higher peak rate, it is necessary to be switched to 2ms TTI from 10ms Τ.

In addition, R99 DCH covering is more than E-DCH lOmsTTI, so when UE is moved to cell edge, though UE it is currently used be E-DCH lOmsTTI, it is possible to covering and still there is problem, it is necessary to which UE is switched into the corresponding TTI of DCH from the OmsTTI of E-DCH 1.

In the prior art, E-DCH Τ switchings include two aspects：Covering measurement and E-DCH TTI The execution flow of switching.

It is covering measurement first, UPH is passed through SI (Scheduling Information, schedule information by UE）Upper 4 is blunt to base station, wherein UPH (UE transmission power headroom, UE transmission power surpluses）, UPH is maximum UE transmission power and DPCCH (Dedicated Physical Control Channel, Dedicated Physical Control Channel）Power ratio.Usual UPH is less than a thresholding, then it is assumed that covering is limited or UE is moved to cell edge, in order to obtain preferably covering, it is necessary to configure lOms TTI;UPH is higher than a thresholding, then it is assumed that UE is moved to center of housing estate, in order to obtain higher peak rate, it is necessary to be configured to 2ms TTI.

Next to that the execution flow that TTI switches, in the prior art, the execution flow that E-DCH TTI switch has synchronously matches somebody with somebody and asynchronous heavy with two methods again, synchronously matches somebody with somebody again and refers to base station controller（Radio Network Control, RNC) respectively to UE and CFN (the Connection Frame Number, Connection Frame Number of base station configuration TTI switchings）, UE is switched to target Τ types in specified CFN, and base station parses the E-DCH data that UE is sent in specified CF according to target Τ types.

It refer to shown in Fig. 1, be the synchronous flow chart matched somebody with somebody again, the synchronous reallocating method includes：

First, RNC determines to perform TTI switchings, and then RNC sends RRC (Radio Resource Control, wireless heterogeneous networks to UE）(radio bearer is again with request for signaling, such as RADIO BEARER RECONFIGURATION REQUEST）Indicate that UE is switched to target Τ types, wherein, radio bearer is matched somebody with somebody again includes activationary time in request（Activation time), activationary time can for example be represented with CF.RNC is to base station（Such as NodeB) send RADIO LINK RECONFIGURATION PREPARE (wireless link reconfigured preparations）New configuration is carried in message, the message, including Τ types；Then base station sends response message to RNC（RADIO LINK RECONFIGURATION Ready, wireless link reconfigured preliminary message）, then RNC is again to base station transmission Radio Link Reconfiguration Confirm (wireless link reconfigured confirmations）Message, wherein, wireless connection is matched somebody with somebody in confirmation message again carries activationary time, for example, also represented with CF, and the activationary time is used to indicate that base station parses upstream data in specified activationary time according to target TTI.Subsequently, (radio bearer is again with response by UE transmission RADIO BEARER RECONFIGURATION RESPONSE）Message is to RNC.

And the asynchronous heavy flow matched somebody with somebody is similar with the synchronous flow matched somebody with somebody again, do not specify activationary time in the message simply, UE is received is switched to target Τ with as early as possible after request again, base station be also it is same, as far as possible The new TTI parsing upstream datas of early utilization, idiographic flow will not be repeated here.

But, the present inventor has found during the technical scheme in realizing the embodiment of the present invention, during existing synchronization is matched somebody with somebody again, RNC notifies UE to perform TTI switchings by RRC signaling, send new configuration information to base station by wireless link reconfigured process simultaneously, need at least to carry out 3 Signalling exchanges between RNC and base station, Τ switchings could be completed, so such handover mechanism can cause TTI switchings not in time, there is larger time delay, especially when switching from 2msTTI to lOmsTTI, being postponed a meeting or conference when such causes E-DCH numbers to lose even call drop according to Lost.And for the asynchronous heavy mode matched somebody with somebody, base station can not accurately determine that UE is switched to target Τ opportunity, matching somebody with somebody again after signaling, it is necessary to attempt to parse according to switching both front and back TTI types, so wasting the hardware resource of base station for RNC transmissions is received.The content of the invention

Wherein, the first TTI is specially 2msTTI, and the 2nd TTI is specially lOmsTTI, i.e., the first TTI and the 2nd Τ are the Τ under E-DCH.

But the Τ Τ Ι that in another embodiment, the first Τ and the 2nd Τ could also belong in different protocol versions, such as the first Τ are the lOmsTTI in E-DCH, and the 2nd Τ is the 20msTTI in R99 DCH.

In specific implementation process, step 101 is specially：User equipment receives corresponding first configuration informations of the first TTI and corresponding second configuration informations of the 2nd TTI that RNC is sent.Wherein, RNC can send the first Τ and the 2nd Τ to UE by dedicated RRC signaling and distinguish corresponding resource allocation information.It should be noted that the first configuration information and the second configuration information can also be predefined, that is, RNC configurations, the method for prioritizing selection RNC configurations, so the present invention is introduced so that RNC is configured as an example are not needed.

In practice, RNC to the UE processes for sending the first configuration information and the second configuration information can be simultaneously, it may not be simultaneously, accordingly, in a step 101, it can simultaneously, may not be simultaneously that UE, which receives the corresponding configuration informations of the first TTI the second configuration information corresponding with the 2nd TTI is received,.

First, it is assumed that the first TTI is 2msTTI, the 2nd TTI is lOmsTTI, for example, initial

After RRC connections are set up, RNC is with regard to prewired lOmsTTI information（Here 4 Jia set UE current Τ as 2msTTI) give UE.

For another example RNC is based on 6a event come the prewired lOmsTTI information of decision-making（It is assumed here that UE current Τ is 2msTTI) give UE, wherein, 6a event refer to that the total transmission powers of UE are more than default threshold value, so UE just reports total transmission power to RNC, then RNC can just need prewired lOmsTTI information to UE according to 6a event decision-makings.

In a further embodiment, when RNC sends the first configuration information and the second configuration information at the same time During to UE, while also specifying the currently used Τ types of UE, under normal conditions, in order to prevent call drop, RNC can specify the currently used Τ of UE to be 10msTTI.

Further, in RNC is sent the first configuration information and the second configuration information, respectively comprising the corresponding a set of Enhanced-DedicatedChannel Media access contorl streams of each TTI（E-DCH MAC-d flow) parameter, for example, based on E-DCH MAC-d flow Identity (Enhanced-DedicatedChannel MAC-d traffic identifier）(Enhanced-DedicatedChannel MAC-d flows maximum retransmission to the E-DCH MAC-d flow maximum number of retransmissions of configuration）, ACK it is (positive to confirm）Power bias NACK (negative acknowledgments）Power bias or E-DPCCH/DPCCH power offset (data channel and the power bias of control channel）；The corresponding first E-DCH MAC-d flow parameters of first TTI, the second configuration information includes the corresponding 2nd E-DCH MAC-d flow parameters of the 2nd Τ；Further, other specification can also be included, for example, the first TTI and the 2nd TTI points of another ll configure a set of DTX (Discontinuous Transmission, discontinuous transmission）Parameter and/or DRX (Discontinuous Reception, discontinuous reception）Parameter, the application is not construed as limiting.

Further, the first configuration information and/or the second configuration information also include but do not limit what be used for determine send comprising Τ switch instruction confirmation control channel power.TTI switchings indicate that confirmation is used to refer to user equipment and has been received by indication message.

Preferably, in another embodiment, before step 101, UE also reports the capability indication information for supporting TTI switchings to RNC, and such as UE can report the capability indication information in RRC CONNECTION SETUP COMPLETE (RRC connections, which are set up, to be completed) message.

Step 102:User equipment receives the indication message that base station is sent.

It is preferred that base station is to notify UE to perform Τ switchings by physical signaling, for example, UE is notified to perform TTI switchings by HS-SCCH order.Certainly, in actual applications, indication message to UE can also be sent by other physical signaling or non-physical signaling.On base station, how when decision-making sends indication message, and sends which type of indication message, and how to utilize High-Speed Shared Control Channel instruction（HS-SCCH order) indication message is sent, when this part is by embodiment in subsequent descriptions base station side, it is described in detail.

It should be noted that the switching indicate can serve to indicate that UE R99 DCH and E-DCH it Between switch over, but the present invention be by between E-DCH TTI switch exemplified by introduce.

Step 103:Current Τ is switched to target TTI corresponding with indication message by user equipment, wherein, target TTI is the first TTI or the 2nd TTI.If the i.e. before the handover Τ of user equipment is the first Τ, then target Τ is the 2nd TTI, and if the Τ of user equipment is the 2nd TTI before the handover, then target Τ is the first TTI.

Step 104:User equipment sends data to base station with target Τ Τ Ι.

For example, it is assumed that the first Τ Τ Ι are 2msTTI, the 2nd TTI is lOmsTTI, and the TTI of user equipment is 2msTTI before switching, then target TTI is just lOmsTTI, then step 104 with lOmsTTI specifically, send upstream data to base station.

In actual applications, step 104 specifically has a variety of embodiments, and the part will be described in detail later.

By above-mentioned steps it can be seen that, because user equipment can receive the corresponding configuration informations of different TTI respectively first, then after the indication message of base station transmission is received, just directly the current Τ of user equipment can be switched over, and switch to target Τ corresponding with indication message, and base station is sent data to target TTI, so need not be during switching, RNC sends new configuration information to base station again, so also avoiding the need for carrying out multiple Signalling exchange between RNC and base station, so the TTI handoff procedures in the present embodiment are timely, time delay is smaller, so avoiding when 2msTTI switches to lOmsTTI, E-DCH Shuo Ju Lost lose or call drop, simultaneously as switchings of the lOmsTTI to 2msTTI can be performed in time, so peak rate can be improved.

In specific implementation process, after step 102, user equipment does not send confirmation to base station, base station can ensure that user equipment is received by retransmitting indication message, specifically can be by setting the period retransmitted or sending times, the continuous retransmission indication message for example in Is, or continuous retransmission 3 times.And user equipment is after indication message is received, just and then perform step 103 and step 104, accordingly, base station distributes the E-DCH upstream datas just sent respectively using 2msTTI and lOmsTTI parsing user equipmenies using two sets of resources after indication message under.

But in another embodiment, after step 102, before step 104, the switching method also includes step 105:User equipment send confirmation to base station, had been received by with signals base user equipment or Person does not receive indication message.

Wherein, the first embodiment of step 105, (Acknowledgment just confirms user equipment feeding back ACK）Information or NACK (Negative Acknowledge negative acknowledgments）Information is to base station.If having correctly received indication message, then user equipment just sends ACK information to base station, if being not properly received indication message, then user equipment just sends nack message to base station.

Second of embodiment of step 105, user equipment carries E-TFCI (the E-DCH Transport Format Combination Indicator, the form merging instruction of enhancing dedicated transmission channel prohibitted the use of in E-DPCCH）Carry out instruction user equipment and have been received by indication message, wherein, the E-TFCI prohibitted the use of is predefined configurable or reserved.It can for example be configured by RNC, such as using prohibitting the use of in 2ms TTI E-DCH TBS (Transport Block Size, transport block size) table

The E-TFCI is reserved to E-TFCL for another example, it is impossible to be used in normal data transfer, is served only for instruction user and is properly received indication message.

The third embodiment of step 105, user equipment with the corresponding UL of target Τ (Uplink, it is up）Scrambler sends data or control information, to indicate to be correctly received indication message.For example when RNC is to prewired first configuration information of user equipment and the second configuration information, respectively two Τ configure two 4 outstanding yards of SC1 and SC2;So that 2msTTI switches to lOmsTTI as an example, when UE is properly received

After HS-SCCH order, up DPCCH is sent with SC2, after base station is detected, E-DCH is parsed using target TTI.For serving BS, under distribute and be accomplished by attempting the up DPCCH of parsing according to SC1 and SC2 respectively using two sets resources respectively after HS-SCCH order.

4th kind of embodiment of step 105, user equipment carrys out instruction user equipment using the domain information in DPCCH and is correctly received indication message.FBI (feedback information, feedback information can such as be used）Corresponding bit is indicated.

5th kind of embodiment of step 105, user equipment, which is sent, individually carries the merging instruction of non-zero transmission channel format（TFCI physical control channel)（DPCCH) carry out instruction user equipment and have been received by indication message, wherein, non-zero TFCI is predefined, or configurable.

Such as when all business of user equipment are all carried on E-DCH, and currently used TTI types are

E-DCH 10ms, at this moment TFCI domains are 0 in DPCCH;After UE receives indication message（ E-DCH 10ms Τ switch to DCH 10ms Τ indication message）, then send and individually carry non-zero TFCI DPCCH to indicate that UE receives indication message；The TFCI that corresponding base station detects in the DPCCH is nonzero value, then it is assumed that UE is properly received indication message, and non-zero TFCI is predefined or configurable.It should be noted that independent transmission mentioned here refers to DPCCH channels and individually sent, not adjoint Dedicated Physical Data Channel（DPDCH channel) is sent.

6th kind of embodiment of step 105, in this example, it is assumed that user equipment is before the indication message that base station is sent is received, in addition to, user equipment also transmit power surplus（UPH base station) is given, such as when the UPH of user equipment is less than the first thresholding, then user equipment reports UPH to base station.

In the present embodiment, step 105 is specially：When the current Τ of user equipment is E-DCH 2ms TTI, and the UPH values that user equipment is sent are less than first threshold, then user equipment, which sends to carry first and strengthen dedicated transmission channel form, merges instruction（E-TFCI enhancing Dedicated Physical Control Channel (E-DPCCH)), indication message is had been received by with instruction user equipment, and the first E-TFCI is predefined or configurable；Or,

When current Τ is 10ms TTI, and user equipment is sent to the UPH values of base station and is more than Second Threshold, then user equipment, which sends to carry second and strengthen dedicated transmission channel form, merges instruction（E-TFCI enhancing Dedicated Physical Control Channel)（E-DPCCH), indication message is had been received by with instruction user equipment, the 2nd E-TFCI is predefined or configurable.

When the currently used Τ types of user equipment are E-DCH 2ms TTI, and the UPH values that user equipment is sent are less than first threshold, then user equipment is after receiving E-DCH 2ms and switching to 10ms TTI indication message, send the E-DPCCH for carrying the first E-TFCI, to indicate to have been received by indication message, the first E-TFCI is predefined or configurable；It should be noted that when UPH is less than first threshold, then illustrating that user is in power limited or covering constrained state, at this moment can not possibly using higher speed rates E-DCH data, i.e., it is generally acknowledged that at this moment E-TFCI values are smaller；So after UE receives E-DCH 2ms and switches to 10ms TTI indication message, send the E-DPCCH for carrying the first E-TFCI (the first E-TFCI values are larger), it is possible to indicate that the base station UE is properly received indication message.Accordingly, base station has been sent after the indication message that E-DCH 2ms switch to 10ms Τ, detects the E-DPCCH channels for the E-TFCI (i.e. the first E-TFCI) for carrying higher value, Then think that UE receives the Τ indication messages that E-DCH 2ms switch to 10ms.Here the first E-TFCI can be used for E-DCH data transfers, simply when UPH is less than first threshold, UE does not select the first E-TFCI to be used for E-DCH data transfers, so UE can be indicated to receive the indication message of base station transmission with the first E-TFCI.

When the currently used Τ types of user equipment are E-DCH 10ms TTI, and the UPH values that user equipment is sent are more than Second Threshold, then user equipment is received after indication message, the E-TFCI of carrying the 2nd of transmission E-DPCCH, to indicate to have been received by indication message, the 2nd E-TFCI is predefined or configurable.It should be noted that when UPH is more than Second Threshold, then illustrating that user is in cell near point or point midway, at this moment can not possibly using less speed rates E-DCH data, i.e., it is generally acknowledged that at this moment E-TFCI values are larger；After UE, which receives E-DCH 10ms, switches to 2ms Τ indication messages, the E-DPCCH for carrying the 2nd E-TFCI (the 2nd E-TFCI values are smaller, less than the first E-TFCI) is sent.Accordingly, base station has been sent after the Τ indication messages that E-DCH 10ms switch to 2ms, detects the E-DPCCH channels for the E-TFCI for carrying smaller value, then it is assumed that UE receives the TTI handover requests that E-DCH 10ms switch to 2ms.

In addition, no matter step 105 sends confirmation in which kind of mode in above-mentioned four kinds of embodiments to base station, user equipment sends confirmation to base station within the maximum time after receiving the indication message, wherein, maximum time is predefined or configurable.Such as RNC is to one maximum time of user device configuration, then user equipment is just to base station feedback confirmation within the maximum time.

Next, it will be described in the specific implementation process of step 104, first, for the opportunity performed from step 104, if target Τ is the first Τ, during for example, 2msTTI, when user equipment sends data to base station with the first TTI, user equipment sends data to base station after the lower M subframe after having sent confirmation with the first Τ, and wherein M is predefined or configurable, and M is the integer more than or equal to zero；And if target Τ is the 2nd TTI, for example during lOmsTTI, when user equipment sends data to base station with the 2nd TTI, user equipment sends data to base station after N number of CFN under having sent after confirmation with the 2nd Τ, wherein N is predefined or configurable, and N is the integer more than or equal to zero.

Wherein, M and N can configure, and e.g. by RNC to user device configuration, be predefined as The value fixed in the protocol.

Secondly, from the difference of the processing mode to user plane, step 104 specifically has numerous embodiments.Wherein, the first embodiment of step 104, first before step 104, user equipment removes the data that HARQ (Hybrid Automatic Repeat Request, hybrid automatic repeat-request) Slow is rushed in area；User equipment resets up enhancing（MAC-i/is) entity.Wherein, MAC-i/is entities are reset, specific is, for example, that (Transmission Sequence Number, transmit Sequence Number by the variable TSN of MAC layer）Reset to 0.Simultaneously, because data are blanked in MAC layer, so RLC (Radio Link Control of user equipment side, wireless spread-spectrum technology) layer just do not receive network side transmission RLC ACK, then will be rushed in RLC Slow in area and rebuild up enhancing protocol Data Unit（MAC-i PDU), and retransmit MAC-is/MAC-i PDU, that is, perform step 104.

Simultaneously in order to avoid RNC sides MAC-is occurs out of order according to TSN sequences, it is necessary to carry up enhancing entity replacement in E-DCH FP (Frame Protocol, Frame Protocol) or signaling（MAC-is Reset) indicate or up enhancing entity replacement（MAC-i/is Reset) indicate.

Second of embodiment of step 104, user equipment deletes the corresponding first up enhancing protocol Data Units of TTI not sent before successfully switching（ MAC-i PDU )；User equipment builds the corresponding 2nd MAC-i PDU of target Τ, wherein, in the 2nd MAC-i PDU and in the first MAC-i PDU, payload is identical；User equipment sends the corresponding 2nd MAC-i PDU of target Τ.

As shown in Figure 3, in the present embodiment, such as Τ before switching is 2msTTI, so target TTI is lOmsTTI, it so just will not send the corresponding MAC-i PDU of successful 2ms TTI to delete, and be configured to the corresponding MAC-i PDU of 10ms TTI, but payload is kept and 2msTTI-sample, but in order to match 10ms TTI TBS table, it is necessary to fill out padding bit (fillers wherein）.As shown in Figure 3, as long as retransmitting the MAC-i PDU of TSN=2, assuming that 2msTTI payload is 160bit, but in order to match lOmsTTI TBS table, assuming that lOmsTTI TBS table load is 166bit, so just fill out filler, i.e. 6bit, but payload or 160bit in the 2nd MAC-i PDU.

TSN is not reset simultaneously, consistent when keeping with 2msTTI.Therefore, in the present embodiment, it is not necessary to trigger the re-transmission of rlc layer.

The third embodiment of step 104, user equipment will be before physical layer will not send successfully switching Corresponding first data encodings of TTI be corresponding second data of target Τ；User equipment sends the second data.

I.e. in the present embodiment, the MAC-i PDU that successful 2msTTI is not sent are not deleted, but in physical layer by fgs encoder to lOmsTTI, this method requires that the first TTI and the 2nd TTI is to use identical TBS table.

TSN is not reset simultaneously, consistent when keeping with 2msTTI.Method in the present embodiment need not trigger rlc layer re-transmission.

4th kind of embodiment of step 104, user equipment is received after indication message, and the data in HARQ buffer are not removed, and the data in HARQ buffer are built into MAC-i PDU according to target TTI types, base station is sent to；And MAC-i/is entities are reset, TSN is reset to 0..Simultaneously in order to avoid RNC sides MAC-is occurs out of order, it is necessary to which carrying MAC-is reset are indicated in E-DCH FP (Frame Protocol, Frame Protocol) or signaling or MAC-i/is reset are indicated according to TSN sequences.

In another embodiment, user equipment is to the processing mode of user plane after indication message is received：Receive after indication message, new MAC-i PDU are not built, while not removing the data that existing HARQ Slow are rushed in area；When the existing HARQ Slow data transfers rushed in area are finished, user equipment sends the confirmation to the indication message；Next CF of the user equipment after confirmation has been sent is switched to lOmsTTI;Next CF of the base station after confirmation is received thinks to be switched to 10msTTI.I.e. as described previously, user equipment side is predefined or is configured with a maximum time, and within the maximum time, user equipment finishes the HARQ Slow data transfers rushed in area within maximum time, retransmits confirmation to base station.

Embodiment two

In the present embodiment, Τ switching methods will be described from base station side, refer to shown in Fig. 4, this method includes：

Step 201：Base station receives corresponding first configuration informations of the first Τ and corresponding second configuration informations of the 2nd Τ.

In specific implementation process, step 201 is specially：Base station receives corresponding first configuration informations of the first Τ and corresponding second configuration informations of the 2nd TTI that RNC is sent.Wherein, RNC can be by wireless Link reconstitution process sends the first Τ and the 2nd Τ to base station and distinguishes corresponding resource allocation information.Further, step 201 is similar with step 101, and the process that RNC sends the first configuration information and the second configuration information to base station can simultaneously, be may not be simultaneously, detailed process refer to the description to step 101, repeat no more herein.

In a further embodiment, when RNC sends the first configuration information and the second configuration information to base station at the same time, while also specifying the currently used Τ types of UE, under normal conditions, in order to prevent call drop, RNC can specify the currently used Τ of UE to be 10msTTI.

Further, in the first configuration information and the second configuration information that RNC is sent, the corresponding a set of E-DCH MAC-d flow parameters of each TTI are included respectively, that is the corresponding first E-DCH MAC-d flow parameters of the first TTI, the second configuration information includes the corresponding 2nd E-DCH MAC-d flow parameters of the 2nd Τ；Further, other specification can also be included, for example, a set of DTX (Discontinuous Transmission, discontinuous to send) parameters and/or DRX (Discontinuous Reception, discontinuous reception is respectively configured in the first TTI and the 2nd TTI）Parameter, the application is not construed as limiting.

Further, the first configuration information and/or the second configuration information include but not limited the power that what is used to determine the control channel that user equipment transmission switches instruction confirmation comprising Τ；Wherein, Τ switchings indicate that confirmation is used to refer to user equipment and has been received by indication message.

Preferably, in another embodiment, before step 201, base station also reports the capability indication information for supporting TTI switchings to RNC, and such as base station can report the capability indication information in Audit Response (audit response) message.

Step 202:Base station sends the indication message of Τ switchings to user equipment, so that user equipment is able to carry out step 103.

In specific implementation process, base station notifies UE to perform TTI and switch by physical signaling, for example, notify UE to perform Τ switchings by HS-SCCH order.Certainly, in actual applications, indication message to UE can also be sent by other physical signaling or non-physical signaling.

As shown in Table 1, it is the current HS-SCCH order combinations used： Xeodtl as can be seen from Table I, Xeodt2 are 11 and Xodtl, Xodt2, Xodt3 are 010 (or 011,100 etc.）It may be used as the indication message of Τ switchings.

Further, it is preferred that the HS-SCCH order can be triggered the serving E-DCH cell of user equipment in E-DCH RLS set.

In specific implementation process, before step 202, this method also includes：Base station judges whether user equipment needs to carry out TTI switchings, obtains the first judged result；When the first judged result represents that user equipment needs to carry out Τ switchings, base station generation indication message.

In practice, whether decision-making user equipment in base station needs to carry out TTI switchings, can be accomplished in several ways.

First embodiment, if the current Τ of user equipment is 2msTTI, then be judged as whether UPH is less than the first thresholding, and/or upstream data rate（Or the E-TFCI of current Τ user equipmenies selection) whether it is less than the second thresholding, if UPH is less than the first thresholding, and/or upstream data rate（Or the E-TFCI of current TTI user equipmenies selection) it is less than the second thresholding, then mean that user equipment needs to carry out TTI switchings, and be the switching for triggering 2msTTI to lOmsTTI.

Second embodiment, if the current TTI of user equipment is 2msTTI, then base station just counts the UPH for whether having user equipment to report in X Τ in Y Τ and is below the 3rd thresholding, wherein, Y, Ν are the integer more than or equal to 1, and Χ is less than or equal to Υ;And/or upstream data rate（Or the E-TFCI of current Τ user equipmenies selection) whether it is less than the second thresholding；If the UPH for having user equipment to report in X Τ in Υ Τ Τ Ι is below the 3rd thresholding, and/or upstream data rate（Or the E-TFCI of current Τ user equipmenies selection) it is less than the second thresholding, then mean that user equipment needs to carry out Τ switchings, and be the switching for triggering 2msTTI to lOmsTTI.

Wherein, in above two embodiment, the first thresholding and the 3rd thresholding can be with identical, can also be different.

3rd embodiment, if the current TTI of user equipment is lOmsTTI, then be judged as UPH and whether be higher than the 4th thresholding, and/or (Slow rushes area's size to the TEBS of user equipment to report）Whether the 5th thresholding is higher than, if UPH is higher than the 4th thresholding, and/or the TEBS of user equipment to report is higher than the 5th thresholding, then mean that user equipment needs to carry out Τ switchings, and be triggering lOmsTTI to 2msTTI Switching.

4th embodiment, if the current Τ of user equipment is lOmsTTI, so base station counts the UPH for whether having user equipment to report in P Τ in S Τ and is above the 6th thresholding, wherein, S, P is the integer more than or equal to 1, P is less than or equal to S, and/or the TEBS of user equipment to report is higher than the 5th thresholding, if the UPH for whether having user equipment to report in P TTI in S Τ is above the 6th thresholding, and/or the TEBS of user equipment to report is higher than the 5th thresholding, so mean that user equipment needs to carry out Τ switchings, and it is the switching for triggering lOmsTTI to 2msTTI.

Wherein, in above-mentioned 3rd embodiment and the 4th embodiment, the 4th thresholding and the 6th thresholding can be with identical, can also be different., can also be different and in above-mentioned four kinds of modes, the first thresholding and the 4th thresholding can be with identical, and the 3rd thresholding and the 6th thresholding can be with identical, can also be different.

Certainly, in practice, whether base station come decision-making can also perform Τ switchings by other specification or algorithm, and the application is not construed as limiting.

When base station decision-making will perform Τ switchings, then just generate indication message, then perform step

202。

In a further embodiment, this method also includes step 203:Base station receives the confirmation that user equipment is sent.Wherein, the confirmation that base station is received in step 203 is corresponding with the confirmation that user equipment is sent, and confirmation during the method for user equipment side, has been described in detail described in previous embodiment one, so will not be repeated here.

Further, if within maximum time, base station does not receive confirmation, then resend indication message, i.e. repeat step 202, wherein, maximum time is predefined or configurable, and such as RNC configures a maximum time to base station, then base station is just to base station feedback confirmation within the maximum time.In the present embodiment, RNC be the maximum time of user device configuration and be base station configuration maximum time be identical.

In a further embodiment, after step 202, before step 203 or afterwards, this method also includes step 204:Base station sends MAC-i/is Reset to RNC and indicated or MAC-is Reset instructions, so that TSN is set to 0 by RNC.

In a further embodiment, after step 202, before step 203 or afterwards, the party Method also includes step 205:Base station sends the target TTI after the switching of user equipment to RNC.To inform the current Τ of RNC user equipmenies type.FP frames or signaling can for example be passed through（Such as RADIO LINK RESTORE INDICATION or RADIO LINK PARAMETER UPDATE INDICATION) indicate.

In a further embodiment, after step 202, before step 203 or afterwards, this method also includes：The upstream data that user equipment is sent is parsed using target Τ.

For the Τ switching flows of compatible RRC signaling triggering of the prior art, while in order to ensure that only one of which node control Τ switches；Allow RNC to turn off the Τ switching modes of base station triggers, TTI switching is then controlled by RNC, such as in the soft handover area that user equipment is moved, note that the TTI switchings of base station triggers are closed in base station.Therefore, base station has the mode of operation for closing TTI switchings and the mode of operation for opening TTI switchings, and is in base station under the mode of operation for opening Τ switchings, performs step 202.

Further, base station receives the configured information that radio network controller is sent, and base station is switched to the mode of operation for opening Τ switchings by the mode of operation for closing TTI switchings, or base station is switched to the mode of operation for closing Τ switchings by the mode of operation for opening Τ switchings.

In practice, RNC has but is not limited to the sending method of following two configured informations：The first, by being included in reallocation message or relevant configuration information not comprising prewired Τ is indicated；Second, indicate that, when the TTI switching working modes of base station to be closed, prewired Τ relevant configuration information can not be deleted by increasing a display switch in reallocation message.

Such as RNC indicates that TTI switchings are closed in base station by RADIO LINK RECONFIGURATION REQUEST/Response, and optionally, base station is in RADIO LINK RECONFIGURATION

The currently used target Τ types of the user equipment are fed back in Response.

Further, in order to which applied to soft handover field, while step 202 or afterwards, this method also includes：Base station sends configured information to wireless network control, so that radio network controller sends configured information to non-serving base stations, so that the target TTI that non-serving base stations are switched to after switching.

Preferably, the temporal information for switching to target Τ is included in the configured information.

Illustrate the Τ switching methods in the present invention by a specific example again below, first assume base Stand in the mode of operation for opening Τ switchings, refer to shown in Fig. 5, this method includes：Step 301:UE and base station report the ability for supporting Τ to switch to indicate to RNC；

Step 302：The prewired Τ Τ Ι of RNC sides decision-making；

Step 303:UE and base station initial configuration 2msTTI configuration parameters, prewired lOmsTTI configuration parameters；

Step 304:Base station decision-making triggering 2msTTI is switched to lOmsTTI;

Step 305:Base station sends HS-SCCH order triggering Τ switchings；

Step 306:UE carries out Τ switchings；

Step 307:UE is to base station feedback confirmation；

Step 308:Base station sends MAC-is reset to RNC and indicated, optionally, can also be that transmission or MAC-i/is Reset are indicated；

Step 309:Currently used TTI is fed back to RNC in base station;

Step 310:The TTI switchings of base station triggers are closed in RNC decision-makings；

Step 311:RNC notifies base station to turn off Τ switchings；

Step 312:Τ switchings are closed in base station, optionally, and currently used TTI is also fed back to RNC;Step 313:RNC control Τ switchings.

Wherein, step 301- steps 312 are described in detail in the embodiment two of embodiment one, so will not be repeated here, and step 313, it refer to the method flow in Fig. 1.

Embodiment eight, i.e., by taking base station side as an example, Τ switching methods include：Step 803, step 805, can also further include step 807.

The implementation process of Τ switching methods in the present embodiment described in detail below.

First, step 801, RNC sends Τ indication messages to UE and base station, in practice, and the Τ indication messages that RNC is sent to UE can set up message for radio bearer（RADIO BEARER SETUP) or wireless load reallocation message（RADIO BEARER RECONFIGURATION) or transmission channel reallocation message（TRANSPORT CHANNEL RECONFIGURATION), the TTI switch indicating informations that RNC is sent to base station can be wireless link reallocation message（ RADIO LINK RECONFIGURATION REQUEST ).

Further, the Τ switch indicating informations, E-DCH 10ms TTI are switched to for indicating UE from E-DCH 2ms TTI, E-DCH 2ms TTI either are switched to from E-DCH 10ms TTI for indicating UE or are switched to R99 DCH channels for indicating UE from E-DCH 10ms TTI.

Optionally, the first gain factor and the second gain factor are included in the TTI indication messages, first gain factor is used to determine that user equipment transmission does not include the power that Τ Τ Ι switch control channel when indicating confirmation, such as determining with transmission data channel（DPDCH or E-DPDCH) when control channel（DPCCH or E-DPCCH) power；Second gain factor is used to determine that user equipment sends the control channel for comprising Τ Τ Ι switching and indicating confirmation（DPCCH or E-DPCCH) power.The advantage comprising at least two gain factors is in the Τ Τ Ι indication messages, after user equipment receives Τ Τ Ι indication messages, the control channel for carrying the transformat combination that Τ Τ Ι switchings indicate confirmation is sent with bigger power, so as to the base station correct decoding control channel, determine that user equipment is switched to target Τ Τ Ι opportunity.

Corresponding to UE sides, step 802 is carried out, that is, receives the Τ Τ Ι that radio network controller (RNC) is sent Indication message.

Corresponding to base station side, step 803 is carried out, that is, receives the TTI indication messages that radio network controller (RNC) is sent.Wherein, step 802 and step 803 are in practice, it may be possible to while perform, it is also possible to performed when different, depending on the communication conditions of communication network.

Next, UE is carried out step 804, that is, the control channel for carrying transformat combination is sent to base station so that base station can determine that user equipment has been received by indication message based on transformat combination.

In practice, step 804 has numerous embodiments, and concrete example is described as follows：In the first embodiment, step 804 is specially and carries the enhancing dedicated transmission channel form merging prohibitted the use of in enhancing Dedicated Physical Control Channel (E-DPCCH) to indicate（E-TFCI) carry out instruction user equipment and have been received by indication message, wherein, the E-TFCI prohibitted the use of is predefined configurable or reserved.It can for example be configured by RNC, such as use 2ms TTI E-DCH TBS (Transport Block Size, transport block size) E-TFCI is reserved for another example by the E-TFCL prohibitted the use of in table, normal data transfer is cannot be used for, instruction user is served only for and is properly received indication message.Or

User equipment, which is sent, individually carries the merging instruction of non-zero transmission channel format（TFCI physical control channel)（DPCCH) carry out instruction user equipment and have been received by indication message, wherein, non-zero TFCI is predefined, or configurable.

Such as when all service bearers of user equipment are in E-DCH, and the currently used TTI types of user equipment are E-DCH 10ms, at this moment because not having TFCI in R99 business, DPCCH to be 0;After UE receives indication message（E-DCH 10ms TTI switch to DCH 10ms TTI indication message）, then send and individually carry non-zero TFCI DPCCH to indicate that UE receives indication message；The TFCI that corresponding base station detects in the DPCCH is nonzero value, then it is assumed that UE is properly received indication message, and non-zero TFCI is predefined or configurable.It should be noted that independent transmission mentioned here refers to DPCCH channels and individually sent, the channel of not adjoint Dedicated Physical Data Channel (DPDCH) is sent.

For another example when user equipment receives Τ indication messages, and the indication message indicate UE from E-DCH 2ms switch E-DCH 10ms TTI when, user equipment only sends E-DPCCH and not sent out Send E-DPDCH.Optionally, the E-TFCI now included in E-DPCCH is not used in normal data transfer, and the E-TFCI can be predefined, or configurable；Optionally, in order to ensure that the E-DPCCH is detected by base station, peak power that user equipment can allow sends E-DPCCH, or determines with above-mentioned second gain factor the transmission power of the E-DPCCH.This method can also be applied to E-DCH to R99 DCH switching.

For another example when user equipment receives Τ indication messages, and the indication message indicate UE from E-DCH 10ms be switched to R99 DCH when, user equipment only sends DPCCH and does not send DPDCH.Before the handover, the TFCI carried in DPCCH channels is a predefined value, such as is 0;User equipment is received after indication message, sends single DPCCH, and a nonzero value is carried in the single DPCCH；Base station detects the DPCCH channels for the TFCI for carrying nonzero value, then can determine that user equipment has been received by indication message, and then can determine that user equipment is switched to R99 DCH opportunity.This method can also be applied to E-DCH 2msTTI and E-DCH 10ms TTI switching.

Optionally, in order to ensure that the DPCCH is detected by base station, user equipment sends DPCCH with the peak power that allows, or determines with above-mentioned second gain factor the power of the DPCCH.

In this second embodiment, step 804 is specially：When the current Τ of user equipment is 2ms TTI, and user equipment is sent to the power headroom UPH values of base station and is less than first threshold, then user equipment, which sends to carry first and strengthen dedicated transmission channel form, merges instruction（E-TFCI enhancing Dedicated Physical Control Channel)（E-DPCCH), indication message is had been received by with instruction user equipment, the first E-TFCI is predefined or configurable；Or,

When the current Τ of user equipment is 10ms TTI, and the UPH values that user equipment is sent to base station are more than Second Threshold, then user equipment, which is sent, carries the enhancing Dedicated Physical Control Channel that the second enhancing dedicated transmission channel form merging indicates (E-TFCI)（E-DPCCH), indication message is had been received by with instruction user equipment, the 2nd E-TFCI is predefined or configurable.

Specifically, when UPH is less than first threshold, then illustrate that user is in power limited or covering constrained state, at this moment can not possibly use higher speed rates E-DCH data, i.e., it is generally acknowledged that at this moment E-TFCI values are smaller；So after UE receives E-DCH 2ms and switches to 10ms TTI indication message, sending the E-DPCCH for carrying the first E-TFCI (the first E-TFCI values are larger), it is possible to indicate base station The UE is properly received indication message.Accordingly, base station has been sent after the indication message that E-DCH 2ms switch to 10ms TTI, detect the E-DPCCH channels for the E-TFCI (i.e. the first E-TFCI) for carrying higher value, then it is assumed that UE receives the TTI indication messages that E-DCH 2ms switch to 10ms.Here the first E-TFCI can be used for E-DCH data transfers, simply when UPH is less than first threshold, UE does not select the first E-TFCI to be used for E-DCH data transfers, so UE can be indicated to receive the indication message of base station transmission with the first E-TFCI.

When UPH is more than Second Threshold, then illustrates that user is in cell near point or point midway, at this moment can not possibly use less speed rates E-DCH data, i.e., it is generally acknowledged that at this moment E-TFCI values are larger；After UE, which receives E-DCH 10ms, switches to 2ms Τ indication messages, sending the 2nd E-TFCI of carrying, (the 2nd E-TFCI values are smaller, less than the first E-TFCI;Minimum value in either E-DCH transport block size form E-DCH Transport Block Size Table）E-DPCCH.Accordingly, base station has been sent after the Τ indication messages that E-DCH 10ms switch to 2ms, detects the E-DPCCH channels for the E-TFCI for carrying smaller value, then it is assumed that UE receives the Τ handover requests that E-DCH 10ms switch to 2ms.

The step of corresponding to base station side is step 805, receive the control channel for the carrying transformat combination that UE is sent, determine that user equipment has been received by indication message with this, because both sides have had an agreement is switched to target Τ in some radio frames for receiving indication message, for example predefine or pre-configured time point just switches, so base station is assured that user equipment uses target Τ opportunity, then it is known that when decoding the upstream data of user equipment transmission with target TTI corresponding with indication message, so base station need not in the prior art receive RNC again match somebody with somebody signaling after, the hardware resource attempted to parse according to switching both front and back TTI types and cause to waste base station, therefore, method in the embodiment of the present invention can save the hardware resource of base station.

Next, UE performs step 806, target Τ corresponding with indication message is switched at predefined or pre-configured time point, by taking the ms TTI of E-DCH 2ms to E-DCH 10 switchings as an example, user equipment has been sent to be switched after the E-DPCCH or DPCCH that indicate confirmation comprising Τ, and 10ms TTI are switched in next or several radio frames.

Again by taking the ms TTI of E-DCH 10ms to E-DCH 2 switchings as an example, user equipment, which has been sent, to be included TTI switchings are indicated after the E-DPCCH or DPCCH of confirmation, are switched in lower Ν subframe

E-DCH 2ms TTI;N is predefined, or configurable.

Then UE performs step 808, i.e. user equipment and sends handoff completion message with target Τ.Wherein, the handoff completion message is that radio bearer sets up completion message（ RADIO BEARER

SETUP COMPLETE) or load-carrying is wirelessly carried with completion message（ RADIO BEARER

RECONFIGURATION COMPLETE) or transmission channel again match somebody with somebody completion message（TRANSPORT

CHANNEL RECONFIGURATION COMPLETE )„

And for base station side, after step 805, be carried out step 807, i.e., start to decode the upstream data that UE is sent with target TTI at predefined or pre-configured time point, and target Τ is corresponding with indication message.

Specifically, for example when base station, which detects the E-TFCI that is carried in E-DPCCH, and the E-DPCCH, is not used in normal data transfer, then it is assumed that UE has received TTI indication messages；Then base station lower M radio frames or under N number of subframe according to target Τ decode UE send upstream data；Or,

After base station detects the DPCCH for carrying nonzero value, it is believed that UE has received Τ indication messages；Then base station lower M radio frames or under N number of subframe according to target Τ decode UE send upstream data.
