Abstract

In the invention, SRNC sets users' the maximal uplink rate according to the user's QoS attribute; if the non-serving cell is lack of hardware capability, and after the SRNC knows it, it re-sets the maximal uplink rate. According to the currently-used protocol, SRNC can only know the overload situation of non-serving cell, doesn't know the current resource situation of non-serving cell such that the SRNC is not capable to set a suitable maximal uplink rate. By the invention, SRNC can set an accurate maximal uplink rate.

Description

Node B reports the method for maximal uplink rate

Technical field

The present invention relates to mobile communication, particularly Node B reports the method for maximal uplink rate.

Background technology

Existing third generation partner plan (hereinafter to be referred as 3GPP) structure as shown in Figure 1.Be description below to Fig. 1 3GPP system configuration.

101 E-PDN among Fig. 1 (Extern Packet Data Network) are outside public data networks, and various types of bag data are provided.The bag data are transferred to 103 gateway general packet radio service (is GPRS hereinafter to be referred as GPRS) support nodes (is GGSN hereinafter to be referred as Gateway GPRS Support Node) by external network by predetermined interface 102.Interface 102.。。。After GGSN receives data, data are sent to 105 Serving GPRS Support Nodes (hereinafter to be referred as SGSN) by interface 104.Connect by the tunnel between GGSN and the SGSN, interface 104 meets the agreement of gn interface, and the standard of this interface is arranged in TS25.413.After SGSN receives data, need send to 107 service wireless network controllers (hereinafter to be referred as SRNC) to data.In WCDMA, be to connect by the tunnel between SGSN and the RNC, if also do not set up the tunnel of transfer of data, SGSN is by the Data-carrying between 106 transmission message foundation of predetermined interface and the SRNC, if set up the tunnel, SGSN sends to SRNC to data by 106 interfaces.Interface 106 meets the agreement of Iu interface, and the standard of Iu interface comprises the agreement RNSAP agreement of control plane and the agreement of datum plane.The RNSAP agreement comprises the signaling process of setting up datum plane, and datum plane has been stipulated the form in the data of Iu interface transmission.After 107 SRNC receives data, need send to 109 Node B to data.If the bearer context for data transmission between SRNC and the Node B is not also set up, SRNC send by predetermined interface 108 that message are set up and the base station between Data-carrying, and send message and set up Radio Link between base station and UE to UE.After having set up Data-carrying, SRNC is responsible for packing data is become predetermined form, and sending to base station 109,108 interfaces by 108 interfaces is Iub interface, and the standard of Iub interface comprises the agreement NBAP agreement of control plane and the agreement of datum plane.The NBAP agreement has comprised the signaling process of setting up the Iub interface Data-carrying, and the agreement of datum plane has been stipulated the form of the data of Iub interface transmission.109

The base station sends to 110UE to the Radio Link of data by air interface.In order to realize EDCH, hold the sublayer that has increased a Mac-e/es at UE, this layer is the layer below Mac-d.The packet of handling through Mac-d is called as Mac-d flow, and Mac-d flow will give the processing of Mac-e layer then.The packet that process Mac-e layer is handled comprises head and data division the Mac-e packet.The function of Mac-e mainly contains the HARQ function, multiplexing function, the function that transformat is selected.The HARQ function is responsible for handling with HARQ agreement function associated, comprises the packet of preserving Mac-e, and when " non-affirmation " order of receiving that Node B sends, tissue is retransmitted the packet of this Mac-e.The HARQ entity obtains the combination of transformat from RRM module (RRC module), the maximum transmission times of each Mac-d flow, the power information that also has physical layer to need; Multiplexing function is responsible for Mac-d flow is mapped among the PDU of Mac-e, and the data of different Mac-d flow can be multiplexed among the PDU of same Mac-e; The selection of transformat is meant that UE selects suitable transformat, and at first, transformat just is meant the length of the frame of Mac-e.Not every Mac-d flow can be mapped in the frame of Mac-e simultaneously, and which Mac-d flow SRNC will dispose can be multiplexing.SRNC also will to UE dispose one as a reference E-TFC and the power (PO) of the E-TFC correspondence of reference, the power of other E-TFC can calculate according to the PO of the E-TFC of reference.In EDCH, outstanding feature is exactly that Node B can dispatch UE.UE is in the selection of doing transformat, scheduling value according to Node B, according to the transmitting power of UE and the digit rate amount of EDCH, satisfying under the condition of maximum power that transmitting power is not more than Node B scheduling, UE can select a transformat that can transmit maximum data volumes.

In order to realize EDCH, on base station node B, increased the Mac-e layer, to the user of each E-DCH, a Mac-e layer is arranged on Node B.On each Node B, also have the scheduler module of an EDCH, this module and Mac-e handle the function associated with EDCH together.These functions comprise: the scheduling of EDCH, the control of EDCH, the demultiplexing of EDCH, HARQ function.The scheduling of EDCH is meant that Node B manages the resource of whole sub-district, gives different UE the resource allocation of sub-district; The controlled function of EDCH is responsible for receiving " dispatch request " order that UE sends, and the scheduling feature by EDCH, distributes corresponding resource to UE, sends " scheduling distributes " order then and gives UE." dispatch request " order is that UE sends, and can send to Node B together with the Mac-e packet, comprises the size of the buffer area data volume of UE, and available power etc. can provide reference information for the scheduling of Node B; The demultiplexing function of EDCH is meant that the Mac-e layer of Node B the predetermined form of bag composition that receives, sends to SRNC then.The bag that the Mac-e layer is received comprises head and the data division of Mac-e PDU Mac-e PDU.Because between Node B and the SRNC, Data-carrying is to set up a Data-carrying for each Mac-d flow, the Mac-e layer of Node B takes out the data of same Mac-d flow, forms a predetermined form (Mac-es PDU) then, and packet is sent to SRNC.The Mac-e layer receives data from physical layer, if if physical layer can correct decoding, NodeB sends the correctly reception of " affirmations " order (ACK) indication UE data, and UE can send new data in the same process of the next one (process).The correct data that receive are given Mac-e.If physical layer does not have correct decoding, Node B sends " non-affirmation " order (NAK) indication UE, will retransmit these data at a same process.The ACK/NAK order sends by a DPCH HICH.Node B merges the data of data of retransmitting and transmission first, if the energy correct decoding, the data after the decoding are given Mac-e and handled.

On SRNC, increased a Mac-es layer.The Mac-es layer receives the bag that comes from Node B, therefore retransmission mechanism has been arranged, send to SRNC bag be not order, SRNC by analysis package in front the sequence number of face carry out the ordering of packet.

The front said that in EDCH, an outstanding feature was that Node B can dispatch UE.The scheduling of Node B has two kinds, and a kind of is absolute dispatch, and absolute dispatch is meant that Node B is provided with the maximum of the ascending power that UE can use.Absolute dispatch (Absolute Grant) scheduling be the power ratio of EDCH data channel and Dedicated Physical Control Channel, i.e. the power ratio of E-DPDCH/DPCCH, the DPCCH channel is to be used for the dedicated channel of physical layer for transmission control information.Node B dispatches the absolute speed of the uplink of UE by the ratio of the power of scheduling E-DCDCH and DPCCH, below our said scheduling value or power ratio, all be meant the power ratio of maximum E-DPDCH/DPCCH, when the Mac-e/es of UE layer carries out the transformat selection, according to suitable transmission block of power selection, transmission block is meant the size of the data that constantly will transmit at the next one, is equivalent to can convert power to speed.Because power and speed can be exchanged, also be called the maximum rate that Node B scheduling UE sends sometimes.The dispatch of another kind of Node B is relative dispatch, and the dispatch scheduling is speed with respect to the last time relatively, and the speed of UE can raise, and perhaps reduces a predetermined stride.Dispatch sends by DPCH RGCH relatively, and is therefore fairly simple, only needs indication UE speed " rising " " decline " or " maintenance " to get final product.

Absolute dispatch is to send by a public physical channel AGCH, and therefore, in order to distinguish different users, absolute dispatch need comprise the sign of UE.Node B distributes two signs to the user, and the sign of a special use is main E-RNTI sign (PrimaryE-RNTI), and another sign is a time E-RNTI sign (Secondary E-RNTI).By main E-RNTI sign, the speed of Node B scheduling unique user is called specific schedule information, and schedule information can one or more TTI be that unit sends.By inferior E-RNTI sign, Node B can dispatch one group of user's maximum and use speed, and to one group of user's scheduling, can be called is public schedule information, and public schedule information is to send by certain cycle.The E-RNTI sign that Node B distributes at first sends to SRNC, and SRNC sends to UE to user ID by radio resource control signaling (RRC signaling) then.

Send the difference of the E-RNTI that dispatch comprises according to Node B, we are divided into main absolute dispatch and time absolute dispatch to absolute dispatch, the absolute dispatch that we claim to comprise main E-RNTI is main absolute dispatch, claims the absolute dispatch that comprises time E-RNTI to be time absolute dispatch.Main absolute dispatch is the scheduling at a UE, and promptly NodeB sends schedule information at every turn, just sets the maximum power of a UE, and inferior absolute dispatch is the scheduling to one group of UE, and promptly Node B sets the maximum power of one group of UE simultaneously.

Absolute dispatch also will comprise the scheduling value to UE, and the scheduling value is the power ratio of the operable maximum of UE, and this value is that decision UE can use maximum speed.Absolute dispatch also comprises the sign that a process activates, and this sign indication scheduling is that this sign is set to " all " at a porcess or all process, and the expression dispatch is effective to all process.

Under SHO (soft handover) state, have only a sub-district can send absolute dispatching command and relative dispatching command, other sub-district can only send relative dispatching command.The sub-district that can send absolute dispatching command is the Serving cell of UE, Serving cell is according to the upstream rate of power situation with the amount decision user needs that send data of UE, service Node B can send the maximum of absolute dispatch control UE transmission rate, can also send relative dispatch to the user and make user's speed increase or reduce a predetermined stride.

When the downlink quality variation of Serving cell, just need reselect the Serving cell of the good sub-district of downlink quality as UE.At present, Serving cell is to be selected by network, and SRNC comprises the measurement result to the channel quality of adjacent cells according to the measurement report that UE sends in the measurement report, and SRNC selects the Serving cell of the best sub-district of one of them downlink quality as UE.Send signaling then to new Node B, require to set up new Radio Link, perhaps revise existing Radio Link.In message, notify the sign of new Serving cell, set up and Node B between connection, Node B distributes some resources, such as, the resource at the descending scheduling channel of new Serving cell sends response message then to SRNC.SRNC sends the RRC signaling to UE, notifies new Serving cell sign and sets up new radio bearer.

UE listens to the absolute dispatch of Serving cell, receives main absolute dispatch, and UE obeys the scheduling of main absolute dispatch always.If receive inferior absolute dispatch, see last dispatch, if last master scheduling signaling is set to " not activating ", and the sign that process activates is set to " all " or last efficient scheduling is inferior absolute dispatch, and then UE needs decide maximum operable speed according to the inferior absolute dispatch of receiving.Therefore, to each absolute dispatch, UE needs to know that this dispatch is at main or the inferior E-RNTI.

The upstream data of Serving cell dispatched users if upstream data rate is very high, can be introduced bigger Rot to non-service cell.If the Rot of the up reception of speed non-service cell has surpassed the upper limit, non-service cell can send " DOWN " order to the user, and the user receives " DOWN " order, can reduce the transmitting power and the data rate of upstream data.If non-service cell is that non-service cell will report to the Operation and Maintenance of SRNC because the hardware resource disposal ability is not enough, operator can expand hardware resource.

According to present agreement, when the not enough problem of hardware resource disposal ability has taken place non-service cell, non-service cell does not send " DOWN " order and gives the user, but sends to the Operation and Maintenance of SRNC.The hardware resource disposal ability is not enough, also can make non-service cell be in " overburden " state.Because non-service cell is under the overburden state that hardware causes, do not send " DOWN " order and give the user, so the user can't reduce upstream data rate, the overburden state of non-service cell just can not be eased.Therefore, there is company to propose, know that at SRNC the not enough problem of hardware resource ability has taken place non-service cell, SRNC will reconfigure user's maximum upstream rate, Serving cell is received new user's maximum upstream rate, can adjust user's upstream rate, and uplink transmission power is reduced, the up Rot of non-service cell will be along with reduction, thereby removes the overflow status of non-service cell.

Fig. 2 has described the process of dispatching among the EUDCH.The repeating transmission of NodeB control EUDCH.

The Radio Link of 201 SRNC configuration service sub-districts and non-service cell, the Radio Link of 202 SRNC configuration UE, 203 work as the user has data to send out, and the user at first sends the dispatch request signaling, and this signaling comprises user's power situation, user's buffer area situation.After Serving cell is received the dispatch request signaling, send dispatch, come the upstream data rate of dispatched users to the user.204 users begin to send data.If the up reception Rot of non-service Node B has surpassed threshold value, non-service cell sends 206 " DOWN " order, and user's upstream data rate is reduced.If the hardware resource overburden has taken place the Node B of 207 non-service cells, non-service cell need report to SRNC.

According to present technology, the maximum upstream rate that SRNC is provided with the user is the characteristic according to user's data, if the not enough problem of hardware handles ability has taken place in non-service cell, after SRNC learns, reset maximum data rate, according to present agreement, SRNC only knows that extra-heavy situation has taken place non-service cell, but SRNC does not know the user's that non-service cell can be supported maximum upstream rate, SRNC can not be provided with a suitable maximum upstream rate, if it is bigger than normal that SRNC is provided with new maximum upstream rate, the overburden state of non-service cell can not obtain removing, if it is it is less than normal that new maximum upstream rate is set, improper concerning the user.

Summary of the invention

The purpose of this invention is to provide the method that a kind of Node B reports maximal uplink rate,

SRNC can be provided with a suitable new maximum data rate according to the report of non-service cell.

A kind of Node B reports the method for maximum data rate.Comprise step:

1) Node B reports to SRNC to user's maximal uplink rate

2) SRNC reconfigures this user's maximal uplink rate.

The overburden situation that hardware resource causes inadequately if the Node B of non-service cell has taken place, non-service cell can be as far as possible resource allocation to priority level than higher user, the user that priority level is low need reduce upstream data rate.This is that non-service cell realizes relevant, and in a word, the maximum data rate that can support that non-service cell is reported to RNC is at a user.If the Iur interface is arranged, Node B reports earlier and gives DRNC, and DRNC reports to SRNC then.SRNC can send message to Serving cell according to the maximum data rate of non-service cell report, prepares this user's maximum data rate again.According to present standard, Serving cell can send dispatch user's transmission data rate is reduced according to new maximum data rate, thereby has removed the overburden situation of non-service cell.

Embodiment

Fig. 3 is among the present invention, the structured flowchart of Node B.This structured flowchart has related to EUDCH and has followed the relevant module of the present invention.Other module is omitted.Inner solid line is represented internal interface, is to realize being correlated with.The left side of dotted line is the module of control plane, and the right of dotted line is the module of user plane.

The 300th, air interface.Be the interface between Node B and the UE, can transmitting user data and signaling.In the time of command transmitting, signaling is transmitted together with data, interface aloft, and distinguishing signaling or data can not regarded packet as, below, aloft the data of interface and signaling system becomes data.When Node B sends data, all be, form the data frame format that physical layer requires, send to air interface then through after the processing of physical layer 301.NodeB receives the EUDCH data of air interface, also will send to the 303Mac-e layer then at first through the processing of physical layer 301.The Mac-e layer carries out demultiplexing to be handled.The demultiplexing function of EDCH is meant that the Mac-e layer of Node B the predetermined form of bag composition that receives, sends to SRNC then.The signaling that can include dispatch request in the packet that the Mac-e layer is received, the signaling of dispatch request comprise power information and the buffer state information of UE, and the scheduler module of service Node B can decide the dispatch to the user according to the signaling of dispatch request.If comprise the signaling of dispatch request in the packet that the Mac-e module is found to receive, Mac-e sends to scheduler module 305 to the signaling of dispatch request, if data, 303Mac-e sends to 302 frame structures (Frame Protocol, hereinafter to be referred as FP) module, the 302FP module is responsible for the packet after the Mac-e processing is dressed up specific form (Mac-es PDU), packet is sent to SRNC, the form of FP has detailed description in the 3GPP agreement, omit herein, Node B by 307 interfaces, sends to RNC to packet.307 interfaces are the data link between Node B and the RNC, set up before transfer of data.

305 scheduler modules are received the user's that 303 Mac-e layers send over dispatch request signaling, if this user's Serving cell, 305 modules are according to the signaling of dispatch request, in conjunction with the resource situation of oneself, decide an operable upstream data rate of this user, and the operable upstream data rate of user being sent to UE by dispatch, scheduler module 305 sends to UE to dispatch by physical layer 301.If non-service cell, 305 modules do not send the dispatch request signaling at this user.

The hardware resource of 304 module monitors Node B, if hardware resource has surpassed the maximum of available hardware resource, the extra-heavy situation of hardware resource has taken place exactly, 304 modules will be passed through internal interface, tell 305 scheduler modules, 305 modules can be dispatched the user's who oneself controls upstream data rate, but in some cases, the extra-heavy situation of hardware resource still can not obtain removing, 305 scheduler modules also can select to reduce the user's who controls other sub-district upstream data rate, 305 scheduler modules are selected a user, and according to the situation of hardware resource, calculate the recommended value of this user's new maximal uplink rate, if there is not the Iur interface, 305 scheduler modules are told the module to 306NBAP the recommended value of this new maximum upstream rate, and the NBAP module is responsible for sending this user's of NBAP signaling SRNC new maximal uplink rate.If the Iur interface is arranged, 305 scheduler modules are told the module to 306NBAP the recommended value of new maximum upstream rate, and the NBAP module is responsible for notifying this user of DRNC new maximal uplink rate, and DRNC is again by RNSAP message informing SRNC.Another mode is to pass through the 302FP module, sends to SRNC or DRNC.The 302FP module can produce two kinds of FP, and a kind of is the FP of data, comprises packet header and data, and a kind of is the FP of control, is special FP, only comprises some control informations, does not have data.Can report to RNC to the operable maximal uplink rate of new user by control FP, control FP comprises the sign of UE and the value of maximal uplink rate.Also can be by the packet header notice RNC of data FP.

Fig. 4 is the structured flowchart of SRNC.Only described with the present invention's module relevant with EUDCH.401 interfaces are with the Data-carrying between the Node B when not having the Iur interface to exist, if there is the Iur interface to exist, are that SRNC follows the Data-carrying between the DRNC.SRNC receives data from 401 interfaces, gives 402FP resume module, if control frame, 402 give 406 control module control frame.If Frame, 402 modules are given the 403Mac-es layer packet and are handled, and are through the processing of 404RLC layer and the processing of 405PDCP module then, give the upper strata.

406 control modules are received control frame, the type of analysis and Control frame, if " maximal uplink rate ", and the Iur interface exists, 406 modules send to the 407RNSAP module to maximal uplink rate that comprises in the control frame and user's sign, the 407RNSAP module sends a new message or utilizes existing message, send to DRNC by 409 interfaces, transmit message by DRNC and give service Node B, reconfigure user's maximal uplink rate, 409 interfaces are that the signaling between SRNC and the DRNC connects.If there is not the Iur interface to exist, 406 modules send to the 408NBAP module to maximal uplink rate that comprises in the control frame and user's sign, the 408NBAP module sends a new message or utilizes existing message, send to Node B by 410 interfaces, 410 interfaces are that the signaling between SRNC and the Node B connects.

The situation that has the Iur interface to exist, SRNC also can receive the message that DRNC sends from 407 modules, certain user's of announcement new maximal uplink rate, interface by inside, 408 modules obtain this user's new maximal uplink rate, and 408 modules can send to this user's maximal uplink rate the Node B at Serving cell place by a piece of news.

The situation that does not have the Iur interface to exist, SRNC also can receive the message that non-service Node B sends from 408 modules, certain user's of announcement new maximal uplink rate, 408 modules can send to this user's maximal uplink rate the Node B at Serving cell place by a piece of news.

Fig. 5 does not have under the situation of Iur interface existence, and non-service cell is told the method for the maximum data rate that SRNC is new by the NBAP signaling.

501 non-service cells send message to SRNC, notify new user's maximum data rate, non-service cell can send a new message " overburden notice " and give SRNC, the sign that comprises UE in the message, also comprise the new maximal uplink rate of this UE, can also comprise an extra-heavy reason is " hardware resource is not enough ".Non-service cell also can send an existing message to SRNC, such as, increase a new information element in " Radio Link Failure request ": new maximal uplink rate, and an indication is arranged, the indication failure cause is " hardware resource is not enough ".

502 SRNC receive the message that non-service cell sends, and know non-service cell overburden, and know new maximal uplink rate, and SRNC sends message to Serving cell, disposes a new maximal uplink rate.Maximum data rate can send to Serving cell by a new message " maximal uplink rate is reshuffled ", perhaps give Serving cell by an existing message informing, such as, increase a new information element in " radio link reconfiguration ": new maximal uplink rate.

Fig. 6 has under the situation of Iur interface existence, and non-service cell is told the method for the maximal uplink rate that SRNC is new by the NBAP signaling.

601 non-service cells send message to DRNC, notify a new user's maximal uplink rate, non-service cell can send a new message " overburden notice " and give DRNC, the sign that comprises UE in the message, also comprise the new maximal uplink rate of this UE, can also comprise an extra-heavy reason is " hardware resource is not enough ".Non-service cell also can send an existing message to DRNC, such as, increase a new information element in " Radio Link Failure request ": new maximal uplink rate, and an indication is arranged, the indication failure cause is " hardware resource is not enough ".

602 DRNC give SRNC by RNSAP message, and new maximal uplink rate can be passed through an existing RNSAP message informing SRNC, such as, increase a new information element in " overburden notice " message: new maximal uplink rate.Also can pass through a new message, comprise the sign of UE in the new message, also comprise the new maximal uplink rate of this UE, can also comprise an extra-heavy reason is " hardware resource is not enough ".

603 SRNC receive the message that DRNC sends, and know non-service cell overburden, and know user's new maximal uplink rate, and SRNC sends message to Serving cell, new maximal uplink rate of configure user.Maximal uplink rate can send to Serving cell by a new message " maximum data rate is reshuffled ", perhaps give Serving cell by an existing message informing, such as, increase a new information element in " radio link reconfiguration ": new maximal uplink rate.

Fig. 7 is that non-service Node B tells the maximal uplink rate that SRNC is new by a new control frame.CRC is 7 bits, and the FT1 bit if be arranged to 1, is represented this control frame, if be arranged to 0, represents this Frame.The control frame type increases a new type: maximal uplink rate.Control frame comprises user's sign, and this sign is the sign that SRNC can discern, and such as U-RNTI, control frame also comprises the non-service NodeB new maximal uplink rate of user's setting for this reason.

Fig. 8 is the action flow chart of non-service cell.In 801 steps, Node B will detect the situation of internal resource, such as hardware resource, and power etc.In 802 steps, Node B finds to be in the overburden situation, and Node B can judge whether can pass through to send in 803 steps " DOWN " order, reduce some users' transmitted power, remove extra-heavy situation, if can, carry out 804 steps, Node B sends " DOWN " order, the user who receives " DOWN " order will reduce transmitted power, and Node B continues 801 steps then, detects inner resource situation.If Node B is under extra-heavy situation, can not remove extra-heavy situation by sending " DOWN " order, such as, the overburden situation that the hardware resource deficiency causes, Node B carries out 805 steps, select a user's radio bearer, the principle of selecting can be according to priority level, select the radio bearer of lowest priority, the present invention does not get rid of the principle of other selection, and according to the situation of hardware resource, Node B determines this user's radio bearer to allow the maximum data rate that uses, in EDCH, Node B need report in 806 steps that the overburden of Node B is indicated and new maximal uplink rate is given RNC.In 805 steps, Node B also can select a plurality of users' radio bearer, be respectively these users and determine to allow the maximum data rate that uses, then, by 806 steps, send message to SRNC, report UE sign and new maximum data rate, the message of 806 steps can be the signaling of radio bearer transmission to each user, signaling comprises the maximum data rate of permission, also can send to RNC to these users' maximum data rate by a signaling, comprise these users' sign and corresponding maximum data rate in the message.Node B continues 801 steps then, detects inner resource situation.

Fig. 9 is the motion flow of SRNC.SRNC receives the maximum data rate of overburden indication that Node B sends and new permission in 901 steps, and SRNC can do different operations.Such as, carry out 902 steps, delete this radio bearer, because this moment, the user receives loaded service on the radio bearer from different sub-districts, and the user merges these radio bearers, if there is not this radio bearer that overburden indication is arranged little to receiving professional influence, SRNC can delete this radio bearer.If this has the radio bearer of overburden indication very big to the influence of business, without it, UE just may not be correct the reception business, SRNC can be in 903 steps, the maximum data rate of reprovision radio bearer, reprovision can send the Node B of message to the Serving cell place by SRNC, and a new maximum data rate is set in message.These operations are to realize being correlated with, and SRNC can adopt other implementation method.

Figure 10 is when having the Iur interface to exist, the motion flow of CRNC.If 601 the message that CRNC receives sends by dedicated signaling, carry out 1001 steps, after CRNC received message, CRNC gave SRNC forwards in 1002 steps by dedicated signaling.If the message of 601 steps that CRNC receives sends by common signaling, carry out 1003 steps, after CRNC receives message, user's sign in 1004 steps analysis message, go up the information of preserving according to CRNC, find the SRNC of user's correspondence, then user ID and corresponding maximum data rate are sent to corresponding SRNC in 1005 steps.
