Embodiment
The embodiment of the invention provides a kind of method for releasing resource, is used to solve the resource release problem of HS-RACH.
In the embodiment of the invention method for releasing resource, discharge the HS-RACH resource, can send explicit signaling by network side (like Node B) or terminal and discharge according to trigger message.Send the method for explicit signaling: can indicate through the signaling of physical layer, also can realize, can also realize through additive method certainly through the control PDU of layer 2.
Triggering Node B makes the trigger message that discharges decision and can be:
The terminal that shows of being sent by the terminal does not have data to send, or shows that the terminal sends data volume and be lower than threshold value, or show the more information of changing district of terminal; Do not have data to send, or show that the terminal sends data volume and be lower than threshold value, or show the more information of changing district of terminal by the detected terminal that shows of Node B self; By the data volume according to the terminal transmission of radio network controller (RNC) transmission, the definite information of changing the SOT state of termination of operation quality requirement that the terminal belongs to cell load or terminal; Node B self detects the information that the data error rate that sends at said terminal in the setting-up time is higher than a setting.Wherein, The terminal that shows of being sent by the terminal does not have data to send, or shows that the terminal sends data volume and be lower than threshold value, or show the more information of changing district of terminal; The special schedule information SI that can send by terminal (UE), or the indication of special physical layer control channel.
Brief account is schedule information SI once.The content of SI comprises: the buffer memory of the logic channel id that the buffer area medium priority is the highest (4 bit), UE takies the power remaining space of situation, UE (5 bit).The buffer memory of UE takies situation and comprises: the logical channel data of limit priority takies the ratio of all buffer memorys and the state of all buffer memorys.The situation that can take according to the buffer memory among the SI determines whether that needs discharge resource.
The method for releasing resource that the embodiment of the invention provides can be directed against following three kinds of situations at least:
1) UE remains on CELL_FACH (forward access channel status), and changing district does not more have upstream data to send.
2) UE not more changing district but to carry out state exchange, prepare to switch to CELL_DCH (dedicated channel status) or CELL_PCH (PCH state).
3) UE does not carry out state exchange but will carry out the sub-district and change, and continues to send upstream data.
Below in conjunction with accompanying drawing the method for releasing resource of the embodiment of the invention under above-mentioned three kinds of situations described in detail.
Introduce by network side (like Node B) earlier and send three embodiment that explicit signaling discharges.
Embodiment one:
Seeing also Fig. 1, is the embodiment of the invention one method for releasing resource flow chart, and application scenarios is that UE need not move state, and the sub-district is not changed.
Comprise step among Fig. 1:
Step 101, Node B receive the schedule information SI that UE sends;
UE sends SI to Node B when can periodically or have the new data requirement to send during using HS-RACH to send upstream data, carry the metadata cache capacity of UE among the SI;
Schedule information SI can be independent transmission, also can be to be carried in the upstream data to transmit.
Step 102, Node B confirm to require UE to discharge resource according to the information among the schedule information SI that receives;
When Node B found that the metadata cache occupancy of indicating among the SI is lower than certain threshold values or is 0, decision required UE to discharge resource, and self begins also to prepare to discharge the resource relevant with this UE.
Step 103, Node B send one and discharge indication to UE;
The metadata cache occupancy that Node B indicates in SI is 0 o'clock, sends to UE to discharge indication, requires UE to discharge resource.The mode that discharges indication can be following:
Mode is a): use the control PDU of MAC layer, certain bit format combination expression among the control PDU is that resource discharges indication; The control PDU form of MAC layer comprises: head comprises: type indication (being used to show whether be control PDU), the length of PDU, the CRC check value of PDU; The load part comprises: the type bit of control: for example: resource allocation bit, and resource discharges bit, the scheduling indication bit, time adjustment bit, resource change bit, top grade is compared in mass measurement.These bits put 1 the expression below comprise corresponding information, put 0 the expression do not comprise; Perhaps phase antirepresentation.Can comprise for the resource release portion: the concrete resource and the release cause of release.
Mode b): use the control signaling of physical layer to carry out resource release; Such as using special E-TFC (E-DCH Transport Format Combination among the E-DPCCH; The transformat intersection) value; Perhaps use CQI special among the HS-DPCCH (Channel Quality Indicator, channel quality indication) value etc.
The metadata cache occupancy that Node B indicates in SI is not 0 but when being lower than certain threshold values, sends to UE to discharge indication, requires UE to discharge resource.Discharge the mode that the mode of indication also can be as described above; In addition; Discharge indication except indication discharges resource; Can also indicate UE to send at random the stand-by period of inserting once more, can avoid like this, but but frequent initiation inserts UE at random because there are data to send and the uplink interference that causes because Node B forces to discharge the resource of UE.This stand-by period can be that the control PDU through the MAC layer carries, and also can be to indicate through physical layer signaling.The method for expressing of the value of stand-by period can be the multiple of certain chronomere, is 125ms as waiting for unit, and the value of wait is actual when being 256ms, therefore is expressed as 2 and gets final product.
After step 104, UE received and discharge indication, UE sent to Node B and needs data retransmission;
After UE receives and discharges indication, but the packet that will before receiving the release indication, send affirmation (ack) message that does not receive Node B and return earlier retransmits.UE can only retransmit the MAC-i/MAC-E packet that those do not obtain confirming receiving the new data of not redispatching after release is indicated.
Step 105, Node B discharge the related resource of this side UE;
Node B formally discharges the physical resource that UE uses after the packet that correct receiving needs to retransmit.
Step 106, UE carry out resource and discharge;
UE is in retransmission data packet may and obtain carrying out resource after the ack message that Node B returns and discharge, and discharges data cached relevant with physical layer HS-RACH resource process cache and the parameter list and the physical resource of MAC layer.
In addition; Might exist UE to be nack message, perhaps the erroneous judgement of nack message is ack message for the ack message erroneous judgement of Node B feedback, and constantly to Node B retransmission data packet may; This moment can be in Node B and fixed maximum latency of UE side mark or maximum retransmission; The parameter value that both sides are provided with equates that in case arrive maximum latency or arrive maximum retransmission, Node B and UE carry out resource separately at once and discharge.
Need to prove, the metadata cache occupancy of indicating among the SI that the UE that the factor of triggering Node B decision carrying out resource release is described in embodiment sends, can also be: special physical layer control channel indication, indication network does not have data to send; Node B detects the HS-RACH upward signal and is lower than a threshold values and has continued a period of time, or the packet of in a period of time, receiving from UE all is wrong, and perhaps Node B detects UE a period of time in activation cycle does not have data upload etc.
Need to prove that also the embodiment of the invention might not carry out just carrying out resource release after the data re-transmission.
Also need to prove: Node B discharges resource among the embodiment one can have a HS-RACH release of such step: UE transmission response to give Node B before, carries out resource again after Node B reception release responds and discharges.
The technical scheme of embodiment one, the trigger message that the triggering resource discharges can have multiple, and available different modes transmission resource release indication, makes the resource behaviour in service of terminal and network side be consistent.In addition, can also retransmission threshold value be set in retransmission mechanism, prevent constantly to carry out data re-transmitting.
Below introduce the embodiment of the invention two; Application scenarios be UE not more changing district but to carry out state exchange; Comprise that RNC notice Node B carries out resource release and UE notice Node B discharges two kinds of situations, respectively corresponding diagram 2 embodiment of the invention two (a) method for releasing resource flow charts, Fig. 3 embodiment of the invention two (b) method for releasing resource flow chart.
See also Fig. 2 embodiment of the invention two (a) method for releasing resource flow chart, comprise step:
Step 201, RNC receive measurement parameter;
The measurement parameter that RNC receives for example is the business datum amount of present UE or the parameter informations such as operation quality requirement of UE, and these measurement parameters send to RNC by UE through Node B.The load of the sub-district, UE place that RNC also can further combine oneself to measure.
Step 202, RNC confirm change UE state according to measurement parameter;
RNC does not reach situation such as requirement according to the business datum amount of UE above the load quality of service excessive or UE that threshold value, UE belong to the sub-district, and the state of decision change UE is for example adjourned the CELL_DCH attitude with the state of UE.
Step 203, RNC initiate Radio Link and set up process, send Radio Link to Node B and set up request;
The Radio Link that RNC sends is set up in the request and has been carried UE id and activationary time.The effect of UE id is to let Node B know that which UE will adjourn the CELL_DCH state, also is equivalent to notify Node B when the UE transition state, need discharge resource simultaneously.The effect of activationary time is to tell Node B when Radio Link can be launched.
Need to prove that Radio Link is set up in the request also can not carry activationary time.When not carrying activationary time, Node B can launch new physical channel immediately, but because RNC knows for sure the activationary time of UE, so RNC can begin to receive up data when activationary time arrives.
Node B knows and will the HS-RACH resource that UE id is associated be discharged after receiving Radio Link foundation request, sets up Radio Link by request; Send Radio Link to RNC and set up response; Carry out physical layer synchronization with UE, after finishing synchronously, send wireless link recovery message and give RNC; But do not launch immediately, but after activationary time arrives, launch again.
Step 205, RNC send reconfiguration message and give UE;
RNC sends reconfiguration message and gives UE, and indication UE state transition is to the CELL_DCH attitude.It is consistent that the activationary time that carries in the reconfiguration message is set up in the process with Radio Link.Among this embodiment, RNC sends reconfiguration message and requires UE to carry out parameter reprovision and the new configuration of use, means that also UE need discharge original resource when using new the configuration.
Step 206, UE are carried out the parameter reprovision after receiving reconfiguration message, and return to RNC and to reshuffle completion message;
UE will receive that but send the packet that does not receive the affirmation ack message that Node B returns before the reconfiguration message retransmits.The UE new data of after receiving reconfiguration message, can not redispatching can only retransmit the MAC-i/MAC-E packet that those do not obtain confirming.
Step 208, UE and Node B use new configuration after arriving activationary time, discharge resource separately.
After arriving activationary time, Node B discharges the original HS-RACH resource of UE, brings into use new configuration and UE to carry out alternately, launch new configuration behind the UE transition state after, original HS-RACH resource just has been released.
In this embodiment technical scheme, can realize that simultaneously resource discharges through reconfiguration course, setting up at the Radio Link that RNC sends increases UE id and two parameters of activationary time in the request.Can let Node B know that which UE will adjourn the CELL_DCH state through UE id, also be equivalent to notify Node B when the UE transition state, need discharge resource simultaneously.Activationary time can let Node B and terminal know and when launch new configuration.
See also Fig. 3 embodiment of the invention two (b) method for releasing resource flow chart, comprise step:
Step 301-302, this two step are identical with front embodiment step 201-202, no longer detail here.
Step 303, RNC initiate Radio Link and set up process, send Radio Link to Node B and set up request;
Different with step 203 is, the Radio Link that RNC sends is set up and carried activationary time in the request and need not carry UE id.The effect of activationary time is to tell Node B when Radio Link can be launched.
Need to prove that Radio Link is set up in the request also can not carry activationary time.When not carrying activationary time, Node B can launch new physical channel immediately, but because RNC knows for sure the activationary time of UE, so RNC can begin to receive up data when activationary time arrives.
Step 304, Node B set up Radio Link after receiving Radio Link foundation request;
Node B sets up Radio Link by request after receiving Radio Link foundation request, sends Radio Link to RNC and sets up response, carries out physical layer synchronization with UE, and after finishing synchronously, transmission wireless link recovery message is given RNC, but does not launch immediately.
Step 305, RNC send reconfiguration message and give UE;
RNC sends reconfiguration message and gives UE, and indication UE state transition is to the CELL_DCH attitude.It is consistent that the activationary time that carries in the reconfiguration message is set up in the process with Radio Link.
After step 306, UE receive reconfiguration message, carry out the parameter reprovision;
Step 307, UE send the request of release and give Node B;
Send in the request of release and can carry new SI information.The transmission that discharges request can be opportunity: after arriving activationary time, UE sends the request of release and gives Node B, also can be: send immediately after the parameter reprovision is accomplished.
Step 308, UE send to Node B and need data retransmission;
UE will receive that but send the packet that does not receive the affirmation ack message that Node B returns before the reconfiguration message retransmits.The UE new data of after receiving reconfiguration message, can not redispatching can only retransmit the MAC-i/MAC-E packet that those do not obtain confirming.
Step 309, Node B send to UE and discharge indication;
Node B receives the release request of UE, and after receiving the data retransmission of UE transmission, discharges the original HS-RACH resource of UE, sends simultaneously to discharge indication to UE.The Radio Link of the new configuration of Node B simultaneously comes into effect.
Step 310, UE discharge resource after receiving and discharging indication, and use new configuration transmission to reshuffle completion message and give network, and the UE transition state is accomplished.
What need explanation is, also can be that UE sent the request of release and gives Node B after UE accomplished the operation success of reshuffling in the said process, and carrying release cause is that CELL_DCH is arrived in state transition.Node B receives after the release request of UE, sends to discharge to indicate and gives UE.After arriving activationary time, Node B and UE discharge the original HS-RACH resource of UE simultaneously, and the Radio Link of the new configuration of Node B and UE simultaneously comes into effect, and UE uses new configuration to send reprovision and accomplishes message to network, the completion of UE transition state.
Above-mentioned is to describe the situation that UE is moved to CELL_DCH; If move to the CELL_PCH state; Reshuffle completion message owing to the UE that changes the CELL_PCH state over to must send in original configuration, so reshuffle after not having the link establishment process between RNC and Node B, UE to receive the reconfiguration message of RNC; In original configuration, send then and reshuffle completion message; Receive after the affirmation ACK message that RNC returns, send the request of release and give Node B, and send data retransmission to Node B.Node B receives the request of discharging, and after receiving the data retransmission that UE sends, and sends to discharge indication and give UE, discharges completion status migration after all HS-RACH resources by UE.
Need to prove that the embodiment of the invention two might not carry out just carrying out resource release after the data re-transmission.
In this embodiment technical scheme, can realize that simultaneously resource discharges through reconfiguration course, setting up at the Radio Link that RNC sends increases the activationary time parameter in the request, and activationary time can let Node B and terminal know and when launch new configuration.
Introduce embodiment three again:
Seeing also Fig. 4, is the embodiment of the invention three method for releasing resource flow charts, and application scenarios is that UE does not carry out state exchange but will carry out the sub-district and change.
Comprise step among Fig. 4:
Step 401, UE use HS-RACH to send upstream data in current sub-district;
Step 402, UE measure and find to satisfy after the district reselecting condition, and district reselecting is carried out in decision;
Here said district reselecting condition for example is that the relatively poor needs of common-frequency cell signal mass ratio are reselected the good sub-district of signal quality etc., supposes UE in former sub-district 1, finds that the signal quality of sub-district 2 is better than sub-district 1, and cell update is carried out in decision, is updated to sub-district 2.
Step 403, UE send one and discharge the Node B that former sub-district 1 is given in request;
UE send this to discharge request be a special release request, such as the logic channel id that sends the limit priority of filling among the SI is a special retention, for example 1111, all bits all are 0 or 1 among the SI in other words.Can tell the Node B of former sub-district from this particular value, the reason of release is to have changed the sub-district.Perhaps the control PDU of the MAC layer described in embodiment one representes: UE need discharge the HS-RACH resource because of changing district more.
But UE will send the packet that does not receive the affirmation ack message that Node B returns and retransmit before send discharging request.The UE new data of after receiving reconfiguration message, can not redispatching can only retransmit the MAC-i/MAC-E packet that those do not obtain confirming.
The Node B of step 405, former sub-district 1 sends to UE and discharges indication;
The Node B of former sub-district 1 receives the release request of UE, and after receiving the data retransmission of UE transmission, discharges the original HS-RACH resource of UE, sends simultaneously to discharge indication to UE.
After step 406, UE receive and discharge indication, discharge the HS-RACH resource of former sub-district, use the up access-in resource of Target cell 2 to send cell update message more immediately to Target cell 2.
What need explanation is that the embodiment of the invention three might not carry out just carrying out resource release after the data re-transmission, also can after transmission finishes the release request, discharge resource immediately.
In the present embodiment technical scheme, in the time of can confirming to carry out the sub-district replacing through UE, initiatively send resource release request, realize that after Node B down distributing resource discharges indication resource discharges to Node B.
Introduce again by UE and send two embodiment that explicit signaling discharges.
Seeing also Fig. 5, is the embodiment of the invention four method for releasing resource flow charts, and application scenarios is that UE does not carry out state exchange but will carry out the sub-district and change.
Comprise step among Fig. 5:
Step 501, UE use HS-RACH to send upstream data in current sub-district;
Step 502, UE measure and find to satisfy after the district reselecting condition, and district reselecting is carried out in decision;
Here said district reselecting condition for example is that the relatively poor needs of common-frequency cell signal mass ratio are reselected the good sub-district of signal quality etc., supposes UE in former sub-district 1, finds that the signal quality of sub-district 2 is better than sub-district 1, and cell update is carried out in decision, is updated to sub-district 2.
Step 503, UE send one and discharge the Node B that former sub-district 1 is given in indication;
UE send this to discharge indication be a special release indication, such as the logic channel id that sends the limit priority of filling among the SI is a special retention, for example 1111, all bits all are 0 or 1 among the SI in other words.Can tell the Node B of former sub-district from this particular value, the reason of release is to have changed the sub-district.Perhaps the control PDU through the MAC layer realizes.
The Node B of step 504, former sub-district 1 receives after the release indication of UE, discharges the original HS-RACH resource of UE, with the data packet discarding of correctly not receiving in the HARQ entity, no longer waits for the re-transmission of UE;
Step 505, UE have sent and have discharged after the indication; Discharge the HS-RACH resource of former sub-district immediately; The packet of correctly not replied is not retransmitted yet, and then use the up access-in resource of Target cell 2 to send cell update message immediately to Target cell 2.
In the present embodiment technical scheme, in the time of can confirming to carry out the sub-district replacing through UE, initiatively send resource release indication realization resource and discharge to Node B.
Seeing also Fig. 6, is the embodiment of the invention five method for releasing resource flow charts.
Comprise step among Fig. 6:
Step 601, UE use HS-RACH to send upstream data in current sub-district;
Step 602, UE send to Node B and discharge indication;
If UE is not after having the data transmission, or rlc layer, after the buffer data buffer memory of MAC layer was 0 maintenance a period of time, UE thinks also can initiatively discharge resource by the own needs that continue use HS-RACH resource at present again.Discharge indication informing network side Node B through sending HS-RACH, the form of transmission has: through special SI, or the control PDU of MAC layer, or physical layer signaling is as using E-TFC value special among the E-DPCCH or using CQI value special among the HS-DPCCH etc.
Step 603, Node B receive after the release indication of UE, discharge the original HS-RACH resource of UE, to the UE echo reply;
After step 604, UE have sent and discharged indication,, then directly discharge resource,, do not receive that network side replys, then discharge resource voluntarily if exceed the scheduled time if receive in the given time after the replying that Node B returns.
Need to prove that UE also can send and discharge the indication back and directly discharge resource, and need not wait for replying that Node B returns.
In the present embodiment technical scheme, in the time of can confirming to carry out the sub-district replacing through UE, initiatively send resource and discharge indication, and realize that in the back of replying that reception Node B returns resource discharges to Node B.
