Embodiment
Embodiments provide a kind of method for releasing resource, for solving the resource release And Spread of Solute of HS-RACH.
In embodiment of the present invention method for releasing resource, according to trigger message release HS-RACH resource, explicit signaling can be sent by network side (as Node B) or terminal and discharge.Send the method for explicit signaling: can be indicated by the signaling of physical layer, also can be realized by the control PDU of layer 2, certainly can also be realized by additive method.
The trigger message that triggering Node B makes release decision can be:
What sent by terminal shows that terminal does not have data to send or shows that terminal sends data volume lower than threshold value or the information showing terminal more changing district; What self detected by Node B shows that terminal does not have data to send or shows that terminal sends data volume lower than threshold value or the information showing terminal more changing district; The operation quality requirement of the data volume according to terminal transmission sent by radio network controller (RNC), terminal place cell load or terminal determines the information changing SOT state of termination; Node B self detects the information of data error rate higher than a setting of described terminal transmission in setting-up time.Wherein, what sent by terminal shows that terminal does not have data to send or shows that terminal sends data volume lower than threshold value or the information showing terminal more changing district, the special schedule information SI that can be sent by terminal (UE), or special physical layer control channel instruction.
Simply introduce schedule information SI.The content of SI comprises: the logic channel id (4 bit) that buffer area medium priority is the highest, the buffer memory of UE take the power remaining space (5 bit) of situation, UE.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.Situation can be taken according to the buffer memory in SI to determine whether to need releasing resource.
The method for releasing resource that the embodiment of the present invention provides at least can for three kinds of situations below:
1) UE remains on CELL_FACH (forward access channel status), not more changing district, does not have upstream data to send.
2) UE not more changing district but to State Transferring be carried out, prepare be switched to CELL_DCH (dedicated channel status) or CELL_PCH (paging channel state).
3) UE does not carry out State Transferring but will carry out cell change, continues to send upstream data.
Below in conjunction with accompanying drawing, the method for releasing resource of the embodiment of the present invention under above-mentioned three kinds of situations is described in detail.
First introduce and send by network side (as Node B) three embodiments that explicit signaling carries out discharging.
Embodiment one:
Refer to Fig. 1, be the embodiment of the present invention one method for releasing resource flow chart, application scenarios is that UE does not need the state of moving, and community is not changed.
Fig. 1 comprises step:
Step 101, Node B receive the schedule information SI that UE sends;
UE, during use HS-RACH sends upstream data, periodically or can send the data buffer storage capacity carrying UE in SI, SI to Node B when having new data requirement to send;
Schedule information SI can be individual transmission, also can be to be carried in upstream data to transmit.
Step 102, Node B determine requirement UE releasing resource according to the information in the schedule information SI received;
Node B find the data buffer storage occupancy that indicates in SI lower than certain threshold values or be 0 time, determine to require UE releasing resource, and self start also to prepare to discharge the resource relevant to this UE.
Step 103, Node B send a release and are indicated to UE;
When the data buffer storage occupancy that Node B indicates in SI is 0, sends release instruction to UE, require UE releasing resource.The mode of release instruction can be as follows:
Mode is a): the control PDU using MAC layer, and certain bit format combination expression in controls PDU is that resource release indicates; The control PDU form of MAC layer comprises: head comprises: type instruction (for showing whether be control PDU), the length of PDU, the CRC check value of PDU; Loaded portion comprises: the type bit of control: such as: resource allocation bit, resource release bit, scheduling indication bit, time adjustment bit, and resource change bit, top grade is compared in mass measurement.These bits are put below 1 expression and are comprised corresponding information, set to 0 expression and do not comprise; Or phase antirepresentation.Can comprise for resource release portion: the concrete resource of release and release cause.
Mode b): use the control signal of physical layer to carry out resource release, such as use E-TFC (E-DCH Transport Format Combination special in E-DPCCH, transformat intersection) value, or use CQI (Channel Quality Indicator, channel quality indicates) value etc. special in HS-DPCCH.
The data buffer storage occupancy that Node B indicates in SI be not 0 but lower than certain threshold values time, to UE send release instruction, require UE releasing resource.The mode of release instruction also can mode as described above, in addition, release instruction is except instruction releasing resource, UE can also be indicated again to send the stand-by period of Stochastic accessing, can avoid like this because the resource of Node B forcible aborting UE, but the uplink interference that UE but initiates Stochastic accessing frequently because of there being data to send and causing.This stand-by period can be carried by the control PDU of MAC layer, also can be indicated by physical layer signaling.The method for expressing of the value of stand-by period can be the multiple of certain chronomere, and as waited for, unit is 125ms, and the value of wait is actual when being 256ms, is therefore expressed as 2.
After step 104, UE receive release instruction, UE sends to Node B and needs data retransmission;
After UE receives release instruction, but first the packet having sent confirmation (ack) message not receiving Node B and return before receiving release instruction is retransmitted.UE no longer sends new data after receiving release instruction, can only retransmit the MAC-i/MAC-E packet that those are not confirmed.
The related resource of this side UE discharges by step 105, Node B;
Node B, after correct receiving needs the packet retransmitted, formally discharges the physical resource that UE uses.
Step 106, UE carry out resource release;
UE is in retransmission data packet may and carry out resource release after obtaining the ack message that Node B returns, the data cached process cache relevant with physical layer HS-RACH resource of release MAC layer and parameter list and physical resource.
In addition, likely there is the ack message that UE feeds back for Node B and be mistaken for nack message, or nack message is mistaken for ack message, and constantly to Node B retransmission data packet may, now can determine a maximum latency or maximum retransmission at Node B and UE side mark, the parameter value that both sides are arranged is equal, once arrive maximum latency or arrive maximum retransmission, Node B and UE carries out resource release separately at once.
It should be noted that, trigger Node B and determine to carry out the factor of resource release except the data buffer storage occupancy indicated in the SI that the UE described in embodiment sends, can also be: special physical layer control channel instruction, indication network have data to send; Node B detects that HS-RACH upward signal continues for some time lower than a threshold values, or the packet from UE received within a period of time is all wrong, or Node B detection UE a period of time within activation cycle does not have data upload etc.
Also it should be noted that, the embodiment of the present invention just carries out resource release after might not needing to carry out data re-transmission.
Also it should be noted that: in embodiment one, before Node B releasing resource, such step can be had: UE sends after a HS-RACH release response receives release response to Node B, Node B and carries out resource release again.
The technical scheme of embodiment one, the trigger message of triggers resource release can have multiple, and differently can send resource release instruction, and the resource behaviour in service of terminal and network side is consistent.In addition, retransmission threshold value can also be set in retransmission mechanism, prevent from constantly carrying out data re-transmitting.
Below introduce the embodiment of the present invention two, application scenarios be UE not more changing district but to State Transferring be carried out, comprise RNC and notify that Node B carries out resource release and UE notifies that Node B carries out release two kinds of situations, corresponding diagram 2 embodiment of the present invention two (a) method for releasing resource flow chart, Fig. 3 embodiment of the present invention two (b) method for releasing resource flow chart respectively.
Refer to Fig. 2 embodiment of the present invention two (a) method for releasing resource flow chart, comprise step:
Step 201, RNC receive measurement parameter;
The measurement parameter that RNC receives is such as the parameter information such as the business datum amount of current UE or the operation quality requirement of UE, and these measurement parameters send to RNC by UE by Node B.The load of the community, UE place that RNC also can measure further combined with oneself.
Step 202, RNC determine change UE state according to measurement parameter;
RNC exceedes threshold value according to the business datum amount of UE, the load quality of service that is excessive or UE of community, UE place does not reach the situations such as requirement, determines the state of change UE, such as, the state of UE is adjourned CELL_DCH state.
Step 203, RNC initiate wireless link process, send wireless link request to Node B;
UE id and activationary time is carried in the wireless link request that RNC sends.The effect of UE id be allow Node B know which UE will adjourn CELL_DCH state, be also equivalent to notice Node B simultaneously and need releasing resource when UE transition state.The effect of activationary time tells Node B when wireless link can be enabled.
It should be noted that, in wireless link request, also can not carry activationary time.When not carrying activationary time, Node B can enable new physical channel immediately, but the activationary time of the UE that knows for sure because of RNC, so RNC can start to receive up data when activationary time arrives.
Step 204, Node B set up wireless link after receiving wireless link request;
After Node B receives wireless link request, know that the HS-RACH resource that UE id will be associated discharges, wireless link is set up by request, wireless link response is sent to RNC, carry out physical layer synchronization with UE, after synchronous, send wireless link recovery message to RNC, but do not enable immediately, but enable again after activationary time arrives.
Step 205, RNC send reconfiguration message to UE;
RNC sends reconfiguration message to UE, and indicates UE state transition to CELL_DCH state.The activationary time carried in reconfiguration message be consistent in wireless link process.In this embodiment, RNC sends reconfiguration message and requires UE to carry out parameter reconfiguration and use new configuration, also means that UE needs to discharge original resource while using new configuration.
Step 206, UE receive after reconfiguration message, carry out parameter reconfiguration, and return to RNC and reshuffled message;
Step 207, UE send to Node B and need data retransmission;
But UE retransmits having sent the packet not receiving the confirmation ack message that Node B returns before receiving reconfiguration message.UE can not send new data again after receiving reconfiguration message, can only retransmit the MAC-i/MAC-E packet that those are not confirmed.
Step 208, UE and Node B use new configuration after arrival activationary time, respective releasing resource.
When after arrival activationary time, Node B discharges the original HS-RACH resource of UE, and bring into use new configuration and UE to carry out alternately, after enabling new configuration after UE transition state, original HS-RACH resource has just been released.
In this embodiment technical scheme, resource release can be realized by reconfiguration course simultaneously, in the wireless link request that RNC sends, increase UE id and activationary time two parameters.Which UE will adjourn CELL_DCH state Node B can be allowed to know by UE id, is also equivalent to notice NodeB simultaneously and needs releasing resource when UE transition state.Activationary time can allow Node B and terminal know and when enable new configuration.
Refer to Fig. 3 embodiment of the present invention two (b) method for releasing resource flow chart, comprise step:
Step 301-302, this two step are identical with preceding embodiment step 201-202, no longer describe in detail herein.
Step 303, RNC initiate wireless link process, send wireless link request to Node B;
Carry activationary time in the wireless link request sent unlike, RNC with step 203 and UE id need not be carried.The effect of activationary time tells Node B when wireless link can be enabled.
It should be noted that, in wireless link request, also can not carry activationary time.When not carrying activationary time, Node B can enable new physical channel immediately, but the activationary time of the UE that knows for sure because of RNC, so RNC can start to receive up data when activationary time arrives.
Step 304, Node B set up wireless link after receiving wireless link request;
Node B sets up wireless link by request after receiving wireless link request, sends wireless link response, carry out physical layer synchronization with UE to RNC, after synchronous, send wireless link recovery message to RNC, but does not enable immediately.
Step 305, RNC send reconfiguration message to UE;
RNC sends reconfiguration message to UE, and indicates UE state transition to CELL_DCH state.The activationary time carried in reconfiguration message be consistent in wireless link process.
Step 306, UE carry out parameter reconfiguration after receiving reconfiguration message;
Step 307, UE send releasing request to Node B;
Send in releasing request and can carry new SI information.The transmission of releasing request can be opportunity: when after arrival activationary time, UE sends releasing request to Node B, also can be: send immediately after parameter reconfiguration completes.
Step 308, UE send to Node B and need data retransmission;
But UE retransmits having sent the packet not receiving the confirmation ack message that Node B returns before receiving reconfiguration message.UE can not send new data again after receiving reconfiguration message, can only retransmit the MAC-i/MAC-E packet that those are not confirmed.
Step 309, Node B send release instruction to UE;
Node B receives the releasing request of UE, and after receiving the data retransmission of UE transmission, the original HS-RACH resource of release UE, sends release simultaneously and be indicated to UE.The wireless link that Node B newly configures simultaneously comes into effect.
After step 310, UE receive release instruction, releasing resource, and use new configuration transmission to reshuffle message to network, UE transition state completes.
It should be noted that, also can be after UE completes the successful operation of reshuffling in said process, and UE sends releasing request to Node B, and carrying release cause is that CELL_DCH is arrived in state transition.After Node B receives the releasing request of UE, send release and be indicated to UE.When after arrival activationary time, Node B and UE discharges the original HS-RACH resource of UE simultaneously, and the wireless link of the new configuration of Node B and UE simultaneously comes into effect, and UE uses new configuration to send reprovision and completes message to network, and UE transition state completes.
Above-mentioned is describe the situation that UE moves to CELL_DCH, if move to _ FACH state, message has been reshuffled because the UE proceeding to _ FACH state must send in original configuration, so there is no the link establishment process between RNC and Node B, UE reshuffles after receiving the reconfiguration message of RNC, then send in original configuration and reshuffled message, after receiving the confirmation ACK message that RNC returns, send releasing request to Node B, and send data retransmission to Node B.Node B receives releasing request, and after receiving the data retransmission of UE transmission, sends release and be indicated to UE, and after discharging all HS-RACH resources by UE, completion status is moved.
It should be noted that, the embodiment of the present invention two just carries out resource release after might not needing to carry out data re-transmission.
In this embodiment technical scheme, can realize resource release by reconfiguration course, in the wireless link request that RNC sends, increase activationary time parameter, activationary time can allow Node B and terminal know and when enable new configuration simultaneously.
Introduce embodiment three again:
Referring to Fig. 4, is the embodiment of the present invention three method for releasing resource flow chart, and application scenarios is that UE does not carry out State Transferring but will carry out cell change.
Fig. 4 comprises step:
Step 401, UE use HS-RACH to send upstream data in current community;
Step 402, UE measurement discovery determines to carry out cell reselection after meeting cell re-selection conditions;
Here said cell re-selection conditions, such as, be common-frequency cell signal mass ratio poor needs reselect the good community etc. of signal quality, suppose that UE is in former community 1, finds that the signal quality of community 2 is better than community 1, determines to carry out cell update, be updated to community 2.
Step 403, UE send a releasing request to the Node B of former community 1;
This releasing request that UE sends is a special releasing request, such as the logic channel id sending the limit priority filled in SI is a special retention, such as 1111, and bits all in SI is in other words all 0 or 1.Can tell the Node B of former community from this particular value, the reason of release has changed community.Or the control PDU of the MAC layer as described in embodiment one represents: UE needs release HS-RACH resource because of more changing district.
Step 404, UE need data retransmission to the Node B transmission of former community 1;
But UE retransmits having sent the packet not receiving the confirmation ack message that Node B returns before transmission releasing request.UE can not send new data again after receiving reconfiguration message, can only retransmit the MAC-i/MAC-E packet that those are not confirmed.
The Node B of step 405, former community 1 sends release instruction to UE;
The Node B of former community 1 receives the releasing request of UE, and after receiving the data retransmission of UE transmission, the original HS-RACH resource of release UE, sends release simultaneously and be indicated to UE.
Step 406, UE discharge the HS-RACH resource of former community after receiving release instruction, then use the multi-upstream access resource of Target cell 2 to send cell update message to Target cell 2 immediately.
It should be noted that, the embodiment of the present invention three just carries out resource release after might not needing to carry out data re-transmission, also can after being sent releasing request releasing resource immediately.
In the present embodiment technical scheme, when can determine to carry out cell change by UE, initiatively send resource release request to NodeB, after Node B down distributing resource release instruction, realize resource release.
Introduce again and send explicit signaling by UE and carry out two embodiments discharging.
Referring to Fig. 5, is the embodiment of the present invention four method for releasing resource flow chart, and application scenarios is that UE does not carry out State Transferring but will carry out cell change.
Fig. 5 comprises step:
Step 501, UE use HS-RACH to send upstream data in current community;
Step 502, UE measurement discovery determines to carry out cell reselection after meeting cell re-selection conditions;
Here said cell re-selection conditions, such as, be common-frequency cell signal mass ratio poor needs reselect the good community etc. of signal quality, suppose that UE is in former community 1, finds that the signal quality of community 2 is better than community 1, determines to carry out cell update, be updated to community 2.
Step 503, UE send the Node B that a release is indicated to former community 1;
This release instruction that UE sends is a special release instruction, such as the logic channel id sending the limit priority filled in SI is a special retention, such as 1111, and bits all in SI is in other words all 0 or 1.Can tell the Node B of former community from this particular value, the reason of release has changed community.Or realized by the control PDU of MAC layer.
After the Node B of step 504, former community 1 receives the release instruction of UE, the original HS-RACH resource of release UE, by the data packet discarding correctly do not received in HARQ entity, no longer waits for the re-transmission of UE;
After step 505, UE send release instruction, discharge the HS-RACH resource of former community immediately, also the packet not obtaining correct response is not retransmitted, and then use the multi-upstream access resource of Target cell 2 to send cell update message to Target cell 2 immediately.
In the present embodiment technical scheme, when can determine to carry out cell change by UE, initiatively send resource release instruction to NodeB and realize resource release.
Referring to Fig. 6, is the embodiment of the present invention five method for releasing resource flow chart.
Fig. 6 comprises step:
Step 601, UE use HS-RACH to send upstream data in current community;
Step 602, UE send release instruction to Node B;
If UE is not after having data transmission, or rlc layer, the buffer data buffer memory of MAC layer is after 0 maintenance a period of time, and UE thinks that oneself continues the needs of use HS-RACH resource at present again, also can active releasing resource.By sending HS-RACH release instruction informing network side NodeB, the form of transmission has: by special SI, or the control PDU of MAC layer, or physical layer signaling is as CQI value etc. special in special E-TFC value in use E-DPCCH or use HS-DPCCH.
After step 603, Node B receive the release instruction of UE, the original HS-RACH resource of release UE, returns response to UE;
