Description
Technical field
The present invention relates to wireless communication field, relate in particular to the 3G Wideband Code Division Multiple Access (WCDMA) and insert (Wide-bandCode Division Multiple Access, WCDMA) system and time division multiplexing S-CDMA insert (Time Division Synchronized Code Division Multiple Access, TD-SCDMA) a kind of control high speed descending sharing channel (High Speed Downlink Shared Channel, HS-DSCH) Tiao Du method and service HS-DSCH cell switching method in the system.
Background technology
From Release 5,3GPP provide the high speed downlink packet access mechanism (High Speed DownlinkPacket Access, HSDPA), in order to the downlink grouped high-speed transfer of interface aloft to be provided.It is by high-speed downlink shared transmission channel HS-DSCH, high-speed downstream Physical Shared Channel (High Speed PhysicalDownlink Shared Channel, HS-PDSCH), downlink high-speed shared control channel (SharedControl Channel for HS-DSCH, HS-SCCH) and HS-DSCH dedicated uplink physical control channel (Dedicated Physical Control Channel (uplink) for HS-DSCH HS-DPCCH) interacts and to realize.And the HS-DSCH Radio Resource is dispatched by the MAC-hs (scheduling entity of HSDPA) in base station (Node B), schedule information (specifying HS-PDSCH and modulation system thereof) is sent to subscriber equipment (User Equipment on HS-SCCH, UE), UE receives data on the HS-PDSCH of appointment, and on HS-DPCCH feedback reception result and radio channel state, Node B determines the parameter of HS-DSCH and HS-PDSCH next time according to feedback information.
Because MAC-hs is at Node B, (HS-DSCH Transmission Time Interval (TTI) is 2ms simultaneously for Radio NetworkController, RNC) mutual schedule information not need same radio network controller, and the feedback information of HS-DPCCH is also in physical layer, so can accomplish fast dispatch; Again because the HS-PDSCH physical channel can (Channel Quality Indicator CQI) selects different modulation system (such as 16QAM), can improve transmission bandwidth greatly according to the channel quality indication of feeding back on HS-DPCCH.
But the switching of service HS-DSCH sub-district does not have soft handover, and its switching flow comprises as shown in Figure 1:
1, UE measures the 1A incident and triggers measurement report and give RNC;
2, increase a wireless links (Radio Link) to this UE by the Serving RNC decision at Target cell, this Radio Link only comprises dedicated channel, and (Dedicated Channel, DCH) information do not have HS-DSCH information;
3, Serving RNC sends activating set updating to UE, and notice increases dedicated wireless channel at target BS;
4, UE sends activating set updating to Serving RNC and finishes message;
5, through after a while, UE measures best cell conversion incident, and sends the 1D measurement report to Serving RNC; Serving RNC decision initiation service HS-DSCH switches the sub-district, initiates radio link reconfiguration to source Node B, and with the relevant HS-DSCH information deletion of this UE in the cell-of-origin, the cell-of-origin stops at HS-DSCH and goes up to these UE transmission data;
6, Serving RNC notification target Node B sets up the HS-DSCH relevant information for this UE;
7, Serving RNC sends radio bearer reconfiguration message to UE, and notice UE service HS-DSCH switches the sub-district, and the configuration information of informing Target cell and HS-DSCH thereof;
8, after UE finishes radio bearer and reshuffles, return radio bearer to Serving RNC and reshuffle and finish message, service HS-DSCH switches the sub-district and finishes.After this, RNC just can send to UE with the HS-DSCH of data by Target cell.
Send the 1D measurement report to Serving RNC from UE, switch to the sub-district and finish, whole process need general 300 arrives 350ms, and such switching time is to real time business, packet radio voice VoIP particularly, and time delay is oversize.
Current have a lot of researchs all to be devoted to improve the speed that switch service HS-DSCH sub-district, and a kind of HS-DSCH of the prior art switches this in the sub-district and improves one's methods, and is briefly described below:
Receive the 1A measurement report of UE as RNC after,, also be the pre-configured HS-DSCH information of this UE except in Target cell, adding the DCH resource of Radio Link; Be not activated but the HS-DSCH in the Target cell is current, be not scheduled to this UE;
When UE detects best cell conversion incident, send the 1D measurement report, the HS-SCCH of cell-of-origin and Target cell is monitored in beginning simultaneously; After RNC received the 1D measurement report, the notification target sub-district began to dispatch HS-DSCH and gives this UE, and the notification source sub-district stops to dispatch HS-DSCH to this UE; Because HS-DSCH has configured in the step in front,, Target cell given this UE so just can beginning to dispatch HS-DSCH;
After receiving the HS-DSCH schedule information of first Target cell on the HS-SCCH of UE at Target cell, just stop to monitor the HS-SCCH of cell-of-origin, UE sends the high-level signaling reorientation and finishes " Re-pointing Complete ", and service HS-DSCH switches the sub-district and finishes.
With respect to the changing method of agreement regulation among Fig. 1, the prior art method has been carried out the configuration of HS-DSCH in advance, and the switching of not notifying UE to serve the HS-DSCH sub-district by top signaling simultaneously can be shortened switching time greatly.
In sum, this is improved one's methods and comprises following characteristics:
One, pre-configured HS-DSCH information is given UE in Target cell;
Two, UE monitors the HS-SCCH of cell-of-origin and Target cell simultaneously;
Three, after UE receives first HS-DSCH schedule information of Target cell, UE sends high-level signaling " Re-pointing Complete ", finishes handoff procedure.
Above-mentioned art methods has individual very important disadvantages to be: need UE to monitor the HS-SCCH channel of two sub-districts simultaneously, this will increase the complexity of UE, and incompatible with existing protocol.This method is in handoff procedure, and first notification target sub-district begins to dispatch HS-DSCH and gives this UE, and back notification source sub-district stops scheduling.Can cause UE to receive the schedule information of two sub-districts simultaneously like this, UE need abandon the schedule information of cell-of-origin, causes the cell-of-origin waste of radio resources like this.In addition, when Target cell sent the HS-DSCH frame for the first time to UE, because the downlink wireless channel situation of this UE reception is not understood, this method suggestion sent a clear data to obtain the feedback information of this UE, will waste a HS-DSCH frame like this.
Summary of the invention

Fig. 1 is the service HS-DSCH sub-district switching flow figure of protocol definition;
Fig. 2 is service HS-DSCH sub-district switching flow figure of the present invention;
Fig. 3 does not serve HS-DSCH sub-district switching flow figure for RNC decision of the present invention.
Embodiment
Referring to Fig. 2, be service HS-DSCH sub-district switching flow figure of the present invention, idiographic flow comprises:
1, after UE measures the 1A incident, sends Radio Resource control (Radio ResourceControl, RRC) measurement report to Serving RNC.
2, after Serving RNC is received the 1A measurement report, increase a Radio Link that comprises DCH to current UE at target Node B by the Serving RNC decision.
3, Serving RNC sends the Radio Link assignment to target Node B and prepares (Radio LinkReconfiguration Prepare) message, disposes the HSDSA information (HS-DSCH information) of this UE at target Node B.
4, after target Node B finishes configuration, return the Radio Link assignment to Serving RNC and be ready to (RadioLink Reconfiguration Ready) response message.
5, Serving RNC sends activating set updating to UE, and notice increases dedicated wireless channel at target BS.
6, UE sends activating set updating to Serving RNC and finishes message.
7, Serving RNC sends radio bearer reconfiguration message to UE, and notice UE has determined service HS-DSCH sub-district is switched, and informs the configuration information of Target cell and HS-DSCH thereof.
8, after UE finishes radio bearer and reshuffles, return radio bearer to Serving RNC and reshuffle and finish message.
9, after UE detects best cell conversion incident, send the 1D measurement report to RNC.
10, UE sends on uplink physical channel HS-DPCCH simultaneously and feeds back to source Node B, and CQI field wherein is set to 0 or 31 (in order to improve the reception accuracy, can send this HS-DPCCH frame continuously 3 times, or wait for the affirmation information that source Node B sends on HS-SCCH); The HS-SCCH that stops to monitor the HS-SCCH of cell-of-origin then and begin the intercept target sub-district; After source Node B receives that this CQI is 0 or 31 feedback information, stop to dispatch the HS-DSCH resource and give this UE, but do not delete the HS-DSCH configuration information of this UE and the data in the buffering area.
In the practical application, this method also can be after UE sends the 1D measurement report, waits for the duration of certain setting, sends the HS-DPCCH frame of CQI=0 for source Node B again, after sending this HS-DPCCH frame, the HS-SCCH that begins the intercept target sub-district again stops to monitor the HS-SCCH of cell-of-origin simultaneously.Send the HS-DPCCH frame of CQI=0 or 31 behind the wait setting duration again, its benefit is before switching to Target cell, can continue the HS-DSCH data of reception sources sub-district, reduces in the handoff procedure time of service interruption.The time value that this is given can be by system information broadcast (SystemInformation Broadcast, SIB) information acquisition that reads Target cell.Can increase a field in the SIB3 of existing protocol standard definition, called after " service HS-DSCH switches the stand-by period in the sub-district " is realized, and is broadcast to all UE in the sub-district by SIB3.Concrete wait for duration by RNC according to rational duration of self treatment mechanism configuration (when guaranteeing that Target cell has begun to dispatch HS-DSCH, UE has stopped monitoring the HS-SCCH of cell-of-origin, and the HS-SCCH of beginning intercept target sub-district).
Regulation in current 3GPP agreement [2], when CQI was 0 value, this CQI did not have definition, be 31 o'clock be invalid field, it is that 0 value or 31 values come notification source Node B to stop to dispatch the HS-DSCH resource to UE that the present invention utilizes this CQI, can not cause conflict with other CQI definition in its existing protocol.Certainly, the present invention also can utilize other fields (such as ACK/NACK) in the HS-DPCCH channel, or increases new field, or defines other CQI value, reach by the HS-DPCCH channel and stop to dispatch the purpose of HS-DSCH resource by UE notification source sub-district, the present invention does not limit this;
In this step 10, UE is 0 or 31 the HS-DPCCH frame except sending CQI for source Node B, can also send the HS-DPCCH frame to Target cell simultaneously, and the value that its CQI is a current goal sub-district radio channel state is set, instruct Target cell to select the suitable automatic repeat requests of mixing (HybridAutomatic Repeat reQuest, HARQ) parameter, improve Target cell and give first HS-DSCH protocol Data Unit (Protocol Data Unit, PDU) transmission accuracy and the channel utilization of this UE; Because UE measures Common Pilot Channel (Common Pilot Channel at Target cell, CPICH), so even without beginning to receive the HS-DSCH frame, also can instruct Target cell to select suitable parameters to send first HS-DSCH frame by the CQI value of feedback current goal sub-district radio channel state.
11, when Node B receive UE on the HS-DPCCH stop dispatching command after, on HS-SCCH by in the HS-SCCH frame define field give the value of agreement, or return confirmation of receipt message to user terminal by the field that increases newly, acknowledge receipt of and cease and desist order, and stop to dispatch the HS-DSCH resource of this HS-DPCCH affiliated subdistrict to this UE.
12, after RNC receives the 1D measurement report, activate the HS-DSCH information that this UE is given in configuration among the target Node B, notification target Node B begins the resource to this UE scheduling HS-DSCH, can begin to send the HS-DSCH frame simultaneously and dispatch to target Node B; Target cell sends the HS-DSCH frame that receives to UE by HS-DSCH.
In the present invention, RNC does not send the HS-DSCH configuration information that radio link reconfiguration (RL Reconfiguration) information order source Node B deletes this UE.The HS-DSCH configuration information keeps always in the cell-of-origin, withdraws from the Active Set (Active Set) of this UE up to the cell-of-origin.Like this, if the service HS-DSCH sub-district of UE needs to switch go back to this cell-of-origin once more, can have same switch speed.Otherwise just need reconfigure HS-DSCH, switching time just up to 300～350ms (the same) with background technology.Therefore, among the present invention,,, also dispose HS-DSCH information simultaneously, but wouldn't activate, when service HS-DSCH sub-district switches to this sub-district, just can be activated except increasing DCH as long as there is a sub-district to enter the Active Set of UE.But in the prior art, when service HS-DSCH sub-district switching takes place after, can be with the HS-DSCH configuration information deletion of cell-of-origin, when causing secondary to switch go back to this cell-of-origin, switching time is elongated.
Simultaneously because the present invention need not send top signaling Re-pointing Complete notice RNC finishing switching by UE, so switching time is also quicker than prior art.
Because the present invention adopts physical layer signaling HS-DPCCH frame to stop scheduling by UE notification source Node B, it is fast to begin scheduling than RNC notification target Node B, so the situation that two sub-districts of the prior art send the HS-DSCH frame simultaneously can not occur.
In sum, the present invention does not need additionally to increase the ability of UE, can compatible well current standard.According to said method of the present invention, whether no matter have the HS-DSCH data to send to this UE, source Node B needs to receive and handle the up HS-DPCCH channel of this UE.Because HS-DPCCH is and uplink special physical channel (Dedicated Physical Channel, DPCH) bundle, the up DPCH of UE in the cell-of-origin do not have deleted, and source Node B need receive the up DPCH data of this UE, so can receive the HS-DPCCH channel of this UE yet.
In above-mentioned handoff procedure, if not serving the HS-DSCH sub-district, the RNC decision do not switch, then flow process comprises as shown in Figure 3:
Step 1-10, with the description of above-mentioned flow process shown in Figure 3, do not repeat.
Step 11, Serving RNC send radio bearer and reshuffle (RB Reconfiguration) to UE, notify it to switch back source Node B.
After step 12, UE receive that this radio bearer is reshuffled signaling, send a new HS-DPCCH frame to source Node B, and appropriate C QI value (wireless status according to current measurement is provided with) is set.Simultaneously, UE stops the HS-SCCH of monitored object Node B, the HS-SCCH channel of beginning monitor source Node B.Source Node B receives that this CQI is not behind 0 or 31 the HS-DPCCH frame, begins to dispatch the HS-DSCH resource and gives this UE.
Step 13, UE reshuffle to Serving RNC transmission radio bearer and finish message.
Because it is behind 0 or 31 the HS-DPCCH frame that source Node B of the present invention receives CQI, do not delete the HS-DSCH configuration information of this UE and the data in the buffering area, therefore, when receiving that again CQI is not 0 or 31 HS-DPCCH frame, just can recover scheduling immediately and send data.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
