Description

The E-DCH service authentication control method

Technical field

The present invention relates to mobile communications network, particularly high-speed uplink packet access technique.

Background technology

Third generation partner program (3rd Generation Partnership Project, abbreviation " 3GPP ") vital tissue as moving communicating field has promoted 3G (Third Generation) Moblie (The Third Generation, be called for short " 3G ") standardization effort of technology, the carrying of uplink and downlink business all is based on dedicated channel in its early stage protocol version.

Along with the development of mobile communication technology, 3G technology is also in constantly development evolution.High speed downlink packet inserts (High Speed Downlink Packet Access is called for short " HSDPA ") and high speed uplink packet access (High Speed Uplink Packet Access is called for short " HSUPA ") is exactly the important evolution of 3G technology.The scheduling of the packet among HSDPA and the HSUPA and re-transmission etc. are controlled by base-station node (Node B).

Wherein, HSDPA was introduced in 3GPP the 5th edition as down high-speed data bag access technology, and (Release 5 in 2002, abbreviation " R5 ") in the version, and 3GPP the 6th edition (Release 6, abbreviation " R6 ") carried out in partly improving, it adopts 2 milliseconds of shorter (ms) Transmission Time Intervals (Transmission Timing Interval is called for short " TTI "), to realize quick self-adapted control.Use adaptive coding and modulation (Adaptive Modulation and Coding is called for short " AMC ") and mix automatic repeat requests (Hybrid Auto Repeat reQuest is called for short " HARQ ") in physical layer.

HSUPA is called the dedicated channel (Enhanced Dedicated Channel, be called for short " E-DCH ") of enhancing again, as the high speed uplink data packet access technique, also has been incorporated among the 3GPP R6 in 2004.Similar with HSDPA, HSUPA has also adopted 2ms TTI and shorter frame length to realize quick self-adapted control, use HARQ and based on the fast uplink dispatching technique of Node B, improved up spectrum efficiency, also have remarkable advantages such as uplink speed is fast, propagation delay time is little, thereby provide more effective support for the application of grouping data services such as real-time game business, file are uploaded, broadband multimedia services.

Agreement relevant with HSUPA in wireless air interface (Uu interface) is from control plane, mainly be divided into three layers: physical layer (Physical) is ground floor, media access control protocol layer (Medium AccessControl, be called for short " MAC ") and radio link control (Radio Link Control, abbreviation " RLC ") layer is the second layer, and corresponding radio resource control protocol (Radio Resource Control is called for short " RRC ") layer is the 3rd layer.

In physical layer, for subscriber equipment (User Equipment, abbreviation " UE ") high-efficiency transfer of upstream data, E-DCH has increased two uplink physical channels and three down physical channels newly, they are respectively up E-DCH Dedicated Physical Data Channel (the E-DCH Dedicated PhysicalData Channel that is used for carrying user data, be called for short " E-DPDCH "), be used to transmit accompanied by physical layer signaling, for the E-DPDCH demodulation provides the up E-DCH Dedicated Physical Control Channel of following signaling (E-DCH Dedicated PhysicalControl Channel, be called for short " E-DPCCH "), be used to control E-DCH absolute grant channel (the E-DCH Absolute Grant Channel of the uplink speed of UE, be called for short " E-AGCH ") and E-DCH relative authorization channel (E-DCH Relative Grant Channel, be called for short " E-RGCH "), and be used to carry the E-DCH HARQ answering indication signal channel of confirmation (ACK/NACK) (E-DCH HARQ Indicator Channel is called for short " E-HICH ") of the affirmation of Node B/not.

Authorization of service (Serving Grant is called for short " the SG ") parameter that the up fast packet scheduling of E-DCH is based on Node B control realizes.In order to simplify the control of the up fast packet scheduling of E-DCH, a UE only preserves a SG parameter, so the transmission of the upstream packet of all HARQ processes of this UE all is subjected to this SG parameter control.The current SG parameter that UE preserves is by the absolute grant that is carried on E-AGCH (AbsoluteGrant) order, and relative authorization (Relative Grant) the order control that is carried on E-RGCH.Wherein, the absolute grant order is made up of the absolute grant value and one the 1 bit long absolute grant scope (Absolute Grant Scope) of one 5 bit long, and the absolute grant value is as shown in table 1, and the absolute grant order then is a single-bit amount.Because E-AGCH is a common signal channel, therefore E-AGCH also provides the sign that needs to receive this order and be subjected to the UE of its control in each absolute grant order of transmission, it is E-DCH Radio Network Temporary Identifier (E-DCH Radio Network Temporary Identity is called for short " E-RNTI ").

Table 1

The up fast packet scheduling of E-DCH is supported two kinds of packet scheduling modes, is respectively the mode of independently dispatching based on single UE and is the group scheduling mode of object with UE group.Wherein, in single UE independence scheduling mode, Node B can independently carry out shut-down operation (only to the 2msTTI pattern) or activate all HARQ processes simultaneously each HARQ process of this UE, simultaneously, UE had both accepted the control from the absolute grant order of E-AGCH, also accepted the control from the relative authorization command of E-RGCH; And in the group scheduling mode, all HARQ processes are always enlivened and UE can only accept the control from the absolute grant order of E-AGCH.E-DCH allows a UE to dispose this two kinds of scheduling modes simultaneously, and dynamically indicates UE should accept the control of which kind of scheduling mode by Node B.

E-DCH service Node B is respectively basic E-RNTI (Primary E-RNTI) and the 2nd E-RNTI (Secondary E-RNTI) for the UE of each configuring E-DCH channel disposes two E-RNTI simultaneously.Wherein, basic E-RNTI typically is used for the independent scheduling to single UE, and the 2nd E-RNTI typically is used for the scheduling of UE group.

UE preserves three internal state variable, be respectively current authorization of service (Serving_Grant) variable, be used to indicate second authorization value (Stored_Secondary_Grant) variable of the storage of the authorization of service that basic E-RNTI adopted when the 2nd E-RNTI switches, and whether be used to indicate current be basic mandate available (Primary_Grant_Available) variable of basic E-RNTI control mode.In addition, UE also uses absolute grant timer (AG_Timer), and in the timing of absolute grant timer, the absolute grant order that UE accepts is not subjected to the influence from the relative authorization command of E-RGCH when making by basic E-RNTI control.

According to 3GPP agreement TS25.321 and motion " R2-060747; AG_Timer for IE " ServingGrant " (the absolute grant timer of information element " authorization of service "); 2006-02 ", when the E-DCH Serving cell changed, the method to set up of three internal state variable of UE as shown in Figure 1.

In step 101, at first activate all HARQ processes of UE.

Then, in step 102, judge whether high-level signaling carries information element (InformationElement, be called for short " IE ") " Serving Grant Value (authorization of service value) " and " Primary/SecondaryGrant Selector (basic/second authorized and select) ", if comprised this two IE, then changed step 103 over to; Otherwise change step 104 over to.

In step 103, UE utilizes the parameter of these two IE that the value of its internal state variable Serving_Grant, Primary_Grant_Available and Stored_Secondary_Grant is set.

In step 104, Serving_Grant in its internal state variable of UE continuation use and the currency of Primary_Grant_Available, and its state variable of initialization Stored_Secondary_Grant is " Zero_Grant ".

Yet, the situation that the E-DCH Serving cell changes mainly contains two kinds, according to TR25.931 and the TS25.331 of 3GPP, a kind of is under E-DCH Active Set (Active Set) the not change situation, and the E-DCH Serving cell that causes because of E-DCH is wireless link reconfigured changes; Another kind is E-DCH Active Set when change, increases or E-DCH Serving cell that deletion service E-DCH Radio Link is caused changes (the wireless link reconfigured and E-DCH Active Set change of E-DCH the E-DCH Serving cell also may not take place changes).

E-DCH Serving cell change under the both of these case all can be subdivided into: the E-DCH Serving cell change in the Node B, the E-DCH Serving cell between the Node B change.

Specifically, when the E-DCH Serving cell in Node B changed, new E-DCH Serving cell still belonged to original E-DCH service Radio Link collection (Radio Link Set is called for short " RLS ").TR25.931 and TS25.331 according to 3GPP, when such E-DCH Serving cell changes, Serving RNC (ServingRNC, abbreviation " SRNC ") IE such as " Activation time (activationary time) " that carries in " RADIO BEARER RECONFIGURATION (radio bearer the reprovision) " message by RRC, " E-DCH Info (E-DCH information) ", notice UE carries out the switching of E-DCH Serving cell at the activationary time of appointment.

Wherein, the IE that comprises among the IE " E-DCH Info " " E-DPDCH Info (E-DPDCH information) " is as shown in table 2, wherein, the IE that is comprised " Scheduled Transmission configuration (scheduled transmission configuration) " further also comprises IE " Serving Grant ".

Table 2

UE is then at this activationary time, come the configuring E-DCH channel according to given parameter among the IE " E-DCH Info ", stop to receive the absolute grant order of original E-DCH Serving cell simultaneously, and begin to receive the absolute grant order of new E-DCH Serving cell, also return " RADIO BEARERRECONFIGURATION COMPLETE (the radio bearer reprovision is finished) " message to SRNC.Wherein, UE is provided with its internal state variable according to " Serving Grant Value " and the value of " Primary/SecondaryGrant Selector " that the IE " Serving Grant " that receives is comprised.

And the E-DCH Serving cell between Node B is when changing, and new E-DCH Serving cell does not belong to original E-DCH service RLS.TR25.931 and TS25.331 according to 3GPP, when such E-DCH Serving cell changes, SRNC carries IE such as " Activation time ", " E-DCH reconfiguration information (E-DCH reconfiguration message) " by " ACTIVE SET UPDATE (activating set updating) " message of RRC, notice UE upgrades Active Set and carries out the switching of E-DCH Serving cell at the activationary time of appointment.

Wherein, IE " E-DCH reconfiguration information " is as shown in table 3, and the IE that is comprised " E-DCH RL Info new serving cell (new Serving cell E-DCH wireless link information) " also further comprises optional IE " Serving Grant ".And comprise " ServingGrant Value " and " Primary/Secondary Grant Selector " among the IE " Serving Grant " too.

Table 4

UE upgrades Active Set at this activationary time, and the parameter configuration E-DCH channel that provides according to " E-DCH reconfiguration information ", the absolute grant order that stops to receive the absolute grant order of original E-DCH Serving cell simultaneously and begin to receive new E-DCH Serving cell, and return " ACTIVE SET UPDATE COMPLETE (activating set updating is finished) " message to SRNC.Equally, UE is provided with its internal state variable according to " Serving Grant Value " and the value of " Primary/SecondaryGrant Selector " among the IE that is received " Serving Grant ".

When UE switches to new E-DCH Serving cell, agreement TS25.321 according to 3GPP, and motion " R2-060764; E-DCH Serving Grant Update (renewal of E-DCH authorization of service); 2006-02 ", to the changing method between the dynamic indication of the scheduling mode of UE and the two kinds of scheduling modes as shown in Figure 2.

In step 201, UE receives the absolute grant order on E-AGCH.

In step 202, judge whether UE sign is basic E-RNTI, and the absolute grant value is " INACTIVE (non-activation) ", if then change step 203 over to; Otherwise change step 209 over to.

In step 203, judge that whether " Absolute Grant Scope (absolute grant scope) " is " PerHARQ process (single HARQ process) ", and be the 2msTTI pattern, if then change step 204 over to; Otherwise change step 205 over to.

In step 204, stop current HARQ process, finish this absolute grant process of commands.Process ends.

In step 205, judge that whether the absolute grant scope is " All HARQ process (all HARQ processes) ", and disposed the 2nd E-RNTI, if then change step 206 over to; Otherwise change step 207 over to.

In step 206, UE activates all HARQ processes, and switch to the 2nd E-RNTI control mode by basic E-RNTI control mode, simultaneously, internal state variable is set, specifically, make Serving_Grant=Stored_Secondary_Grant, Primary_Grant_Available is false (False).And enter step 207.

In step 207, judge that the absolute grant scope is all HARQ processes, and do not dispose the 2nd E-RNTI, be the 2msTTI pattern, if then change step 208 over to; Otherwise, finish this absolute grant process of commands, process ends.

In step 208, stop all HARQ processes, process ends.

In step 209,, then change step 210 over to if the absolute grant value is not non-activation; Otherwise, finish this absolute grant process of commands, process ends.

In step 210, judge whether the sign of UE is the 2nd E-RNTI, if then change step 211 over to; Otherwise, change step 212 over to.

In step 211, upgrade Stored_Secondary_Grant, promptly preserve this absolute grant value in the Stored_Secondary_Grant variable, and enter step 212.

In step 212, judge whether the sign of UE is the 2nd E-RNTI, and Primary_Grant_Available is false, if then change step 213 over to; Otherwise, finish this absolute grant process of commands, process ends.

In step 213, current SG is changed to this absolute grant value, and enters step 214.

In step 214, judge whether the sign of UE is basic E-RNTI, if then change step 215 over to; Otherwise, finish this absolute grant process of commands, process ends.

In step 215, Primary_Grant_Available is set is true (True), and enter step 216.

In step 216, judge whether the absolute grant scope is single HARQ process, if then change step 217 over to; Otherwise the absolute grant scope is all HARQ processes, changes step 218 over to.

In step 217, activate current HARQ process, and enter step 219.

In step 218, activate all HARQ processes, and enter step 219.

In step 219, start the absolute grant timer, if this timer starts, then restart this timer.Process ends.

Can see from top absolute grant command process flow process, switch to the 2nd E-RNTI control mode, following condition need be set simultaneously by basic E-RNTI control mode:

1.UE be designated " basic E-RNTI ";

2. the absolute grant value is non-activation;

3. the absolute grant scope is all HARQ processes;

4. disposed the 2nd E-RNTI.

And switch to basic E-RNTI control mode by the 2nd E-RNTI control mode, following condition need be set simultaneously:

1.UE be designated " basic E-RNTI ";

2. the absolute grant value is not non-activation;

3. " Primary_Grant_Available " is false.

But when the E-DCH Serving cell between generation Node B changed, if high-level signaling does not dispose IE " Serving Grant ", then UE can continue the currency of user mode variable Serving_Grant and Primary_Grant_Available.Two kinds of situations that following E-DCH authorization of service control can occur:

First kind of situation, if this UE is in basic E-RNTI state of a control in original E-DCH Serving cell, be that state variable Primary_Grant_Available is for true, and current new E-DCH Serving cell adopts the 2nd E-RNTI control mode to this UE, then will produce such problem: new E-DCH Serving cell with this UE by basic E-RNTI control mode before the 2nd E-RNTI control mode is switched, this UE can not respond the absolute authorization of service control command of this new E-DCH Serving cell, and update mode variable Stored_Secondary_Grant only;

Second kind of situation, if this UE is in the 2nd E-RNTI state of a control in original E-DCH Serving cell, be that state variable Primary_Grant_Available is for false, and current new E-DCH Serving cell adopts basic E-RNTI control mode to this UE, then can produce such similar problem equally: receive at this UE before the absolute authorization of service order of the E-DCH Serving cell new from this, this UE can not respond the relative authorization of service control command of this new E-DCH Serving cell.Because in the group scheduling mode, UE can only accept the control from the absolute grant order of E-AGCH, and ignores the relative authorization of service order from E-RGCH.

The above-mentioned inefficacy that either way will cause to the E-DCH scheduling of the UE when the E-DCH Serving cell between Node B changes, thereby the professional service quality (Quality of Service is called for short " QoS ") of scheduled transmission (ScheduledTransmission) that this UE transmits is caused bigger adverse effect on E-DCH.

In addition, the situation that E-DCH Serving cell in the Node B is changed then the problems referred to above can not occur, this is because new E-DCH Serving cell all belongs to same Node B, when UE switches to new E-DCH Serving cell, still can be informed in the information such as SG control mode of original E-DCH Serving cell from Node B, thereby make correct processing.

Summary of the invention

In view of this, main purpose of the present invention is to provide a kind of E-DCH service authentication control method, makes when the E-DCH Serving cell between Node B changes, and new E-DCH Serving cell can be guaranteed UE is carried out effective SG control.

In step 302, SRNC also must provide the initial SG parameter of new E-DCH Serving cell to UE.

In step 303, UE finishes when new E-DCH Serving cell is changed, utilize the initial SG parameter of the new E-DCH Serving cell that SRNC provides that internal state variable Serving_Grant, Primary_Grant_Available and the Stored_Secondary_Grant of UE are set, and do not re-use the currency and initialization " Stored_Secondary_Grant " variable of Serving_Grant, Primary_Grant_Available variable.

Specifically, because new E-DCH Serving cell is the control mode that adopts the 2nd E-RNTI, then basic/second mandate selection the parameter in its authorization of service is " second ", UE upgrades its variable Stored_Secondary_Grant according to the authorization of service value that is provided, and utilize Stored_Secondary_Grant that Serving_Grant (even Serving_Grant=Stored_Secondary_Grant) is set, Primary_Grant_Available is changed to vacation by really changing.UE finishes to the switching of the 2nd E-RNTI control mode from basic E-RNTI control mode.

In step 304, UE responds the SG control of new E-DCH Serving cell finishing after new E-DCH Serving cell conversion according to the internal state variable after being provided with.

The E-DCH service authentication control method of second embodiment of the invention as shown in Figure 4, in E-DCH Active Set change process and the wireless link reconfigured process of E-DCH, when if the E-DCH Serving cell change between Node B takes place, if UE is in the 2nd E-RNTI state of a control at original E-DCH Serving cell, be that state variable Primary_Grant_Available is for false, and current new E-DCH Serving cell adopts basic E-RNTI control mode to this UE, and then new E-DCH Serving cell is specific as follows to the SG control method of this UE.

In step 401, when the E-DCH Serving cell between Node B changed, the Node B of new E-DCH Serving cell must provide initial SG parameter to SRNC.Wherein, new service Node B judges that the foundation that the E-DCH Serving cell between the Node B that takes place changes is in E-DCH Active Set change process and the wireless link reconfigured process of E-DCH: before change, concentrate the service Radio Link that does not comprise original E-DCH at the E-DCH Radio Link that belongs to this UE of this new service Node B, and E-DCH Radio Link newly-increased or reprovision is the service Radio Link of original E-DCH.

This new service Node B can carry initial SG parameter by high-level signaling, and sends SRNC to.For example, high-level signaling is base-station node applying portion (Node-B Application Part, be called for short " NBAP ") or RNS (Radio Network Subsystem Application Part, be called for short " RNSAP ") message, promptly carry the SG parameter by NBAP/RNSAP message, with the attribute of two IE " ServingGrant Value " among the IE in the NBAP/RNSAP message " E-DCH FDD DL Control Channel Information " and " Primary/Secondary Grant Selector " by " O " (Optional, optional) change to " C " (Conditional, based on condition), promptly be set to " C-inter-Node B servingE-DCH cell change " and realize, as shown in table 7.The explanation of this attribute is as shown in table 8, is illustrated under the situation of the E-DCH Serving cell change between NodeB, and these two IE must occur; And in other cases, comprise the situation of initially setting up the E-DCH Radio Link, no E-DCH Serving cell changes generation or the situation that the E-DCH Serving cell in the Node B changes takes place in E-DCH Active Set change process and the wireless link reconfigured process of E-DCH, this IE is that optionally these two IE are optional.

Step 402 is similar to step 302.

In step 403, finish when new E-DCH Serving cell is changed, because new E-DCH Serving cell is the control mode that adopts basic E-RNTI, then basic/second mandate selection the parameter in its authorization of service is " substantially ", UE upgrades its variable Stored_Secondary_Grant according to the authorization of service value that is provided, and utilize Stored_Secondary_Grant that Serving_Grant (even Serving_Grant=Stored_Secondary_Grant) is set, Primary_Grant_Available changed by vacation be changed to very, make effectively the basic E-RNTI control of UE.UE finishes to basic E-RNTI control mode switching from the 2nd E-RNTI control mode.

Step 404 is similar to step 304, does not repeat them here.

The E-DCH service authentication control method of third embodiment of the invention as shown in Figure 5, in E-DCH Active Set change process and the wireless link reconfigured process of E-DCH, SRNC can know that the E-DCH Serving cell that whether has taken place between Node B changes, therefore, the E-DCH Serving cell of indicating UE whether to take place between Node B by newly-increased IE in the high-level signaling of SRNC changes.

In step 501, UE activates all HARQ processes.

In step 502, UE judges whether disposed IE in the high-level signaling " Serving Grant Value " and " Primary/Secondary Grant Selector ", if then change in the step 503; Otherwise, change step 504 over to.

In step 503, because high-level signaling has disposed IE " Serving Grant Value " and " Primary/Secondary Grant Selector ", then UE utilizes these two parameters that its internal state variable Serving_Grant, Primary_Grant_Available and Stored_Secondary_Grant are set.

In step 504, UE handles according to the indication of the newly-increased IE in the high-level signaling.If should indicate the E-DCH Serving cell that has taken place between Node B to change by newly-increased IE, then change in the step 505; Otherwise change in the step 506.

Wherein, high-level signaling can be RRC message, NBAP or RNSAP message.For example, reach an increase new IE " Inter-Node B E-DCH cell change indicator " in " E-DCH reconfiguration information " at the IE of RRC message " E-DPDCH Info ", respectively shown in table 9 and table 10, this newly-increased IE is used in reference to and is shown in E-DCH Active Set change process and the wireless link reconfigured process of E-DCH, and the E-DCH Serving cell that whether has taken place between Node B changes.In addition, different with above-mentioned first and second execution modes, present embodiment does not make an amendment to the attribute of " Serving Grant " of the prior art parameter.

Table 9

Table 10

In step 505, UE is initialized as " Zero_Grant " with variable Serving Grant, and variable Primary_Grant_Available is initialized as true or false, is basic E-RNTI control mode or the 2nd E-RNTI control mode.At last, variable Stored_Secondary_Grant is initialized as " Zero_Grant ".

Like this, when the E-DCH Serving cell change that takes place between Node B, if high-level signaling does not dispose IE " Serving Grant Value " and " Primary/Secondary Grant Selector ", be initialized as definite value by internal state variable Primary_Grant_Available and Serving_Grant with UE, thereby make the absolute authorization of service control mode that new E-DCH Serving cell can know for sure this UE adopted, when having avoided E-DCH Serving cell between Node B to change, do not dispose the problem of the E-DCH authorization of service control fails that initial SG parameter causes owing to high-level signaling.

In step 506, UE continues to use the currency of Serving_Grant and Primary_Grant_Available, and initialization Stored_Secondary_Grant variable is " Zero_Grant ".

High-level signaling in the above-mentioned execution mode is an example with RRC or NBAP/RNSAP message all, those of ordinary skill is understood easily, other high-level signaling also can be realized carrying the SG parameter among the present invention or indicate whether to take place the effect that the E-DCH Serving cell between Node B changes, all not depart from spirit of the present invention.

Though pass through with reference to some of the preferred embodiment of the invention, the present invention is illustrated and describes, but those of ordinary skill in the art should be understood that and can do various changes to it in the form and details, and without departing from the spirit and scope of the present invention.
