Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
Fig. 1 is the method flow schematic diagram of first embodiment of the invention, comprising:
Step 11: the sending node of radio bearer section is determined the QoS parameter of this radio bearer section, so that form the QoS parameter sum of each radio bearer section of whole radio bearer and the QoS parameter of described whole radio bearer is complementary.
Wherein, this radio bearer section can be the RN radio bearer section corresponding with Un interface between the DeNB, also can be the UE radio bearer section corresponding with Uu interface between the RN.For the situation of Un interface, when transfer of data when being descending, sending node is DeNB; When transfer of data when being up, sending node is RN.For the situation of Uu interface, when transfer of data when being descending, sending node is RN; When transfer of data when being up, sending node is UE.
This radio bearer section also can be whole radio bearer, and this sending node is the sending node of whole radio bearer, and for example, when transfer of data when being descending, sending node is DeNB, and when transfer of data when being up, sending node is UE.
The qos parameter sum of each radio bearer section is complementary with the qos parameter of whole radio bearer and refers to: the qos parameter sum of each radio bearer section is identical with the qos parameter of whole radio bearer, and is perhaps, approximate identical according to predetermined strategy.For example, be that time delay is example with the qos parameter, suppose that the time delay on the whole radio bearer is 10ms, then can be configured to 6ms in the radio bearer section of Un interface correspondence, be configured to 4ms in the radio bearer section of Uu interface correspondence; Perhaps, the parameter of two radio bearer sections configuration is increased by a fixed value, for example, all increase 1ms, namely the radio bearer section in Un interface correspondence is configured to 7ms, is configured to 5ms in the radio bearer section of Uu interface correspondence; Perhaps, the parameter of two radio bearer sections configuration is increased by a fixed value in proportion, for example, all enlarge 1.5 times, namely the radio bearer section in Un interface correspondence is configured to 9ms, is configured to 6ms in the radio bearer section of Uu interface correspondence.
When sending node was the sending node of whole radio bearer, the qos parameter that this sending node is determined was the qos parameter on the whole radio bearer.
Step 12: this sending node receives business datum, when the QoS parameter of this business datum is in the satisfiable scope of the QoS parameter of this radio bearer section, transmits described business datum.
For the QoS that solves the multistage radio bearer that has RN guarantees problem, the embodiment of the invention specifically adopts following dual mode:
Mode one: carry out qos parameter in each radio bearer section (for example radio bearer section of the radio bearer section of Uu interface correspondence and Un interface correspondence) and distribute, the qos parameter sum of each section is complementary (namely identical with the qos parameter of whole radio bearer, perhaps, also can the qos parameter of whole radio bearer suitably be relaxed).Because the qos parameter sum of each section is identical with whole qos parameter, when each section all satisfies pre-assigned qos parameter, on the whole, can satisfy the qos parameter on the whole radio bearer equally, therefore, can provide the QoS of whole radio bearer to guarantee.
Mode two: according to the actual transmissions situation of data, obtain the actual QoS parameter, the data of normal process actual QoS parameter in the qos parameter range of needs of whole radio bearer abandon the data of actual QoS parameter outside the qos parameter range of needs of whole radio bearer.All be not dropped owing to do not satisfy the data that QoS guarantees, remaining normal process all are the data that can provide QoS to guarantee, therefore, can provide the QoS on the whole radio bearer to guarantee.
Under above-mentioned dual mode, when specifically implementing, can all carry out the distribution of qos parameter at each radio node (for example, DeNB, RN, UE); Perhaps, can only carry out the configuration of qos parameter at sending node, intermediate node does not carry out the configuration of qos parameter, for example yet, when descending, be configured at the DeNB place, when up, be configured at the UE place, no matter and up or descending, the RN place does not all carry out the configuration of qos parameter.
Present embodiment can be implemented under the multistage radio bearer by the business datum of transmission service quality parameter in the satisfiable scope of the QoS parameter of radio bearer, guarantees for transfer of data provides service quality.
Fig. 2 is the method flow schematic diagram of second embodiment of the invention, and present embodiment is corresponding to above-mentioned mode one.Referring to Fig. 2, present embodiment comprises:
Step 21: the sending node on the radio bearer section and the receiving node of this section are determined the qos parameter set of this section employing through consultation, each qos parameter is arranged according to certain rank in this qos parameter set, on same rank, the qos parameter on each section qos parameter sum and the whole radio bearer is complementary.
Wherein, the radio bearer section can be the RN radio bearer section corresponding with Un interface between the DeNB, also can be the UE radio bearer section corresponding with Uu interface between the RN.For the situation of Un interface, when transfer of data when being descending, sending node is DeNB; When transfer of data when being up, sending node is RN.For the situation of Uu interface, when transfer of data when being descending, sending node is RN; When transfer of data when being up, sending node is UE.
Wherein, certain rank can be type of service or priority (specifically can referring to following embodiment four, five).
Step 22: this sending node obtains business datum waiting for transmission at the required qos parameter of this section.
Concrete, when sending node can be set up according to the carrying under this business datum waiting for transmission, the information that core net sends was determined corresponding qos parameter.For example; as UE during to core network requests real-time game corresponding service data; owing to can preserve the corresponding relation of type of service and qos parameter in the core net usually; therefore; when core net was UE foundation carrying at this real-time game, the qos parameter on the whole radio bearer that can this type of service (real-time game) is corresponding send to DeNB.Afterwards, DeNB is according to the strategy that obtains in advance, and for example, the allocation ratio factor or according to actual conditions such as the channel conditions of Uu interface, Un interface or transmission conditions is distributed to Un interface and Uu interface with whole qos parameter.For the Un interface, sending node (being DeNB) can directly obtain the qos parameter of Un interface assignment, as the required qos parameter of Un interface section; For the Uu interface, sending node (being RN) can receive the qos parameter that DeNB distributes to the Uu interface from DeNB, as the required qos parameter of Uu interface section.
The no sequential restriction relation of step 21 and step 22.
Step 23: when described required service mass parameter was in described the satisfiable scope of section QoS parameter set, this sending node was by the described data to be transmitted of the radio bearer transmissions that can satisfy described required service mass parameter.
Wherein, the radio bearer that can satisfy this required qos parameter can be and the binding of the type of service of these data, perhaps, also can be according to priority can satisfy but not with the radio bearer of type of service binding.
Present embodiment is by carrying out the distribution of qos parameter at each section, makes each section qos parameter sum identical with qos parameter on the whole radio bearer, can exist under the situation of RN, continues to provide the QoS of whole radio bearer to guarantee.Present embodiment can provide the basis for the transmission that has QoS to guarantee of data by distributing the mode of qos parameter.
Fig. 3 is the method flow schematic diagram of third embodiment of the invention, and present embodiment is corresponding to above-mentioned mode two.Referring to Fig. 3, present embodiment comprises:
Step 31: the sending node on the radio bearer section (for example, the corresponding radio bearer of Un interface, the radio bearer of Uu interface correspondence) disposes the qos parameter of this section.
Wherein, when sending node can the carrying under data be set up, dispose the qos parameter of this section, can be that the qos parameter sum of each section is identical with qos parameter on the whole radio bearer, perhaps, the qos parameter of each section is all identical with qos parameter on the whole radio bearer, perhaps, dispose qos parameter on the whole radio bearer at sending node, and intermediate node does not carry out the configuration (specifically can referring to following embodiment six, seven, eight) of qos parameter.
Step 32: this sending node obtains the active service mass parameter of transmitting data.
Wherein, active service mass parameter can be for transmitting data in the actual QoS parameter of the preceding paragraph and/or having transmitted data in the actual QoS parameter of this section.
The no sequential restriction relation of step 31 and step 32.
Step 33: when described active service mass parameter was in the satisfiable scope of the QoS parameter of described section, this sending node continued the described data of having transmitted of transmission.
Present embodiment calculates by the actual conditions to data, and the data that normal process has QoS to guarantee abandon the data that do not have QoS to guarantee, can exist under the situation of RN, continues to provide the QoS of whole radio bearer to guarantee.
Fig. 4 is the method flow schematic diagram of fourth embodiment of the invention, comprising:
Step 401: the sending node on the radio bearer section and receiving node are determined the scale factor of this section employing through consultation.
Wherein, the radio bearer section can be the RN radio bearer section corresponding with Un interface between the DeNB, also can be the UE radio bearer section corresponding with Uu interface between the RN.For the situation of Un interface, when transfer of data when being descending, sending node is DeNB, and receiving node is RN; When transfer of data when being up, sending node is RN, and receiving node is DeNB.For the situation of Uu interface, when transfer of data when being descending, sending node is RN, and receiving node is UE; When transfer of data when being up, sending node is UE, and receiving node is RN.
Step 402: sending node will be consulted definite scale factor and the qos parameter set on the whole radio bearer multiplies each other, and obtain the qos parameter set of this section.
In the LTE system, usually qos parameter and type of service are bound, and the type of service that provides among the 3GPP TS23.203v8.5.0 and the corresponding relation of qos parameter can be referring to tables 1:
Table 1
Multiply by the scale factor that negotiation obtains again on the basis of table 1, be the qos parameter set of this section, as can be known, each qos parameter and type of service in the qos parameter set of this section are bound.
Step 403: sending node obtains the required qos parameter of data.Specifically can be referring to step 22.
Step 404: when this required qos parameter is in this section qos parameter set, sending node and receiving node are set up the radio bearer corresponding with this required qos parameter, because qos parameter and type of service binding, therefore, radio bearer and the type of service of foundation are also bound.
Be specifically as follows: UE sends the professional request of setting up to the MME in the core net, wherein carries the information of data to be transmitted; MME sets up carrying under these data according to the information of this data to be transmitted, and namely MME sends carrying to DeNB and sets up that (Evolved Radio Access Bearer, eRAB) message are wherein carried the type of service of data to be transmitted; DeNB determines this section qos parameter corresponding with this type of service according to the qos parameter set of this type of service and Un interface; DeNB and RN according to should and corresponding this section qos parameter of type of service set up with the corresponding Un interface of type of service on radio bearer; DeNB sets up message by the Un interface bearing this type of service is sent to RN; Be similar to the processing of DeNB, RN also can consult definite scale factor in advance with UE, and obtains the qos parameter set of Uu interface, and qos parameter and type of service in this qos parameter set are bound, and set up the radio bearer on the Uu interface corresponding with this type of service.Afterwards, data can be transmitted at the radio bearer of Uu interface and Un interface.
Step 405: sending node transmits this data by the radio bearer corresponding with required qos parameter (i.e. the corresponding radio bearer of the type of service of these data).
For example, what UE asked is the real-time game of QCI=3, and then each wireless segment is carried on this business (real-time game) of UE request on the radio bearer of real-time game correspondence.
Present embodiment is by carrying out the distribution of qos parameter at each section, makes each section qos parameter sum identical with qos parameter on the whole radio bearer, can exist under the situation of RN, continues to provide the QoS of whole radio bearer to guarantee.Present embodiment can provide the basis for the transmission that has QoS to guarantee of data by distributing the mode of qos parameter.Present embodiment is determined corresponding radio bearer by the mode of qos parameter and type of service binding according to type of service, can utilize the mode of existing qos parameter and type of service binding better, better compatible prior art.
Fig. 5 is the method flow schematic diagram of fifth embodiment of the invention, comprising:
Step 501: the sending node on the radio bearer section and receiving node are determined the qos parameter set of this section employing through consultation, and each qos parameter in this qos parameter set is arranged according to priority.
Because the disposal ability of RN is different with concrete deployment conditions, when RN carries out network access testing, can generate the qos parameter of some limit, for example, for the Un interface between RN and the DeNB, limit delay parameter can be 10ms, and the limit error rate can be 10
-6, suitably expand according to the qos parameter of limiting case measurement or to limit QoS, can determine the qos parameter set according to priority arrangement of this section, this qos parameter set can be as shown in table 2:
Table 2
| The qos parameter index | Time delay | Attribute | The error rate |
| 0 | 10ms | GBR | 10 -6 |
| 1 | 10ms | GBR | 10 -3 |
| 2 | 20ms | GBR | 10 -6 |
| 3 | 20ms | Non-GBR | 10 -3 |
| 4 | 40ms | GBR | 10 -6 |
| 5 | 40ms | Non-GBR | 10 -3 |
The qos parameter index is that 0 expression priority is the highest.
Step 502: sending node obtains the required qos parameter of data.
Step 503: when existence in the qos parameter set of this section can be satisfied the qos parameter of this required qos parameter, sending node and receiving node are set up the radio bearer corresponding with the qos parameter that can satisfy this required qos parameter demand, because the qos parameter of present embodiment is not bound with type of service, therefore, the radio bearer of foundation is not bound with type of service yet.
Step 504: sending node transmits this data by satisfying the radio bearer of required qos parameter.
For example, what UE asked is the real-time game of QCI=3, and as known from Table 1, the required qos parameter of this business comprises: GBR, 50ms, 10
-3, then according to table 2 as can be known, except the qos parameter index is that the radio bearer of each the qos parameter correspondence 3,5 all can satisfy this required qos parameter.Sending node can be determined one at random, for example, the radio bearer of this real-time game correspondence is defined as the radio bearer that the qos parameter index is 1 qos parameter correspondence.
Be understandable that, when the same business of plural UE request, though request is same business, also different radio bearers can be distributed to different UE.For example, UE1 and UE2 all ask the real-time game of QCI=3, be after the radio bearer of 1 qos parameter correspondence is distributed to UE1 with the qos parameter index as RN, RN also can be that the radio bearer of the qos parameter correspondence outside 1 is distributed to UE2 with the qos parameter index, for example, the radio bearer that with the qos parameter index is 2 qos parameter correspondence is distributed to UE2, certainly, if the qos parameter index is the radio bearer of 1 qos parameter correspondence still enough is the UE2 service after distributing to UE1, RN also can be that the radio bearer of 1 qos parameter correspondence is distributed to UE2 with the qos parameter index.
For realizing that the QoS on the whole radio bearer guarantees, be linked into the situation of DeNB by multi-hop RN for UE, for example UE passes through RN1 successively, RN2 is linked under the situation of DeNB, after carry out the node of bearing binding, RN1 for example, bearing binding situation before the needs reference on the wireless path decides the binding of this section, therefore RN1 determine and UE between radio bearer the time, need RN1 can obtain UE and be carried on radio bearer section between RN2 and the RN1 and the bearing binding information on the radio bearer section between DeNB and the RN2, so that in the qos parameter range of needs of the qos parameter sum of each section on whole radio bearer.
Present embodiment is by carrying out the distribution of qos parameter at each section, makes each section qos parameter sum identical with qos parameter on the whole radio bearer, can exist under the situation of RN, continues to provide the QoS of whole radio bearer to guarantee.Present embodiment can provide the basis for the transmission that has QoS to guarantee of data by distributing the mode of qos parameter.Qos parameter is not bound with type of service in the present embodiment, can the dynamic assignment qos parameter, improve flexibility.
Fig. 6 is the method flow schematic diagram of sixth embodiment of the invention, comprising:
Difference pre-configured time delay (Discard Timer) among step 601-602:DeNB and the RN.
Particularly, when business was set up, core net can be set up corresponding carrying for UE, and this carrying has certain qos parameter requirement.Therefore, can set up in the process of carrying (eRAB) for UE core net (corresponding entity is MME), according to the QoS attribute of business, dispose time delay D T1 and DT2 among DeNB and the RN respectively.
For example, suppose that the time delay on the whole radio bearer is T, can be according to channel condition and the transmission quality of Un interface and/or Uu interface, the time delay demand in Un interface and Uu interface configuration is 0.4T and 0.6T respectively.Also can increase some time delays again on the basis of 0.4T and 0.6T, such as all multiply by a coefficient 1.5 on original basis, every section time delay becomes 0.6T and 0.9T respectively, makes overall delay greater than T; Perhaps increase by a fixed delay, become 0.5T and 0.7T respectively as every section time delay, make the overall delay requirement greater than T.
Step 603: be transmitted as example with downlink data, when data arrived DeNB, DeNB puts into the packet data control agreement with these data, and (Packet Data Control Protocol PDCP) in the buffer memory, and was this data startup DT1.
Step 604: after DT1 was overtime, if data also in the PDCP buffer memory, do not send successfully, then DeNB abandoned these data.
Step 605: when during DT1, DeNB successfully sends to RN with these data, then after sending successfully, the duplicate of these data is deleted from buffer memory.For data re-transmission etc. needs, after data send, still will in the PDCP buffer memory, preserve the duplicate of these data usually, when next jump successfully receive these data after, can delete the duplicate of these data.
Step 606:RN puts it in the PDCP buffer memory after receiving the data of DeNB transmission, and is that these data start DT2.
Step 607: be similar to the processing of DeNB, if after DT2 is overtime, data also in the PDCP of RN buffer memory, then abandon these data.
Step 608: when during DT2, RN successfully sends to UE with these data, then after sending successfully, the duplicate of these data is deleted from buffer memory.
Present embodiment is example with the time delay, is understandable that, for other qos parameters, also can adopt the mode of above-mentioned pre-configured parameter to handle.Present embodiment is example with a RN, is understandable that, for plural RN, also can adopt above-mentioned mode to be configured at each RN place.Such scheme is still in the scope of present embodiment.
Present embodiment calculates by the actual conditions to data, and the data that make normal process have QoS to guarantee abandon the data that do not have QoS to guarantee, can exist under the situation of RN, continues to provide the QoS of whole radio bearer to guarantee.Present embodiment is handled according to the actual transmissions situation of data, can improve flexibility.
Among the four-six above-mentioned embodiment, can also comprise: when the channel condition of Un interface and/or Uu interface and transmission quality change or reach predefined cyclic variation during the cycle, DeNB and RN carry out the distribution of qos parameter again according to trigger condition, for example, for the 4th embodiment, consult scale factor again, for the 5th embodiment, again consult the qos parameter set of this section, for the 6th embodiment, reconfigure delay parameter.
Fig. 7 is the method flow schematic diagram of seventh embodiment of the invention, comprising:
Step 701:DeNB and RN handle synchronously.
Particularly, can obtain the timing relationship of Uu and Un interface between DeNB and the RN by the system broadcast message of specific messages or DeNB, for example, the system frame number by the Uu interface (SystemFrame Number, SFN) and the relation between the SFN of Un interface carry out synchronously.
QoS attribute according to business among step 702:DeNB and the RN disposes identical time delay D T respectively, and this DT represents the time delay on the whole radio bearer.
Step 703: be transmitted as example with downlink data, when data arrived DeNB, DeNB put into the PDCP buffer memory with these data, and was this data startup DT.
Step 704: after DT was overtime, if data also in the PDCP buffer memory, do not send successfully, then DeNB abandoned these data.
Step 705: when during DT, DeNB successfully sends to RN with these data, then after sending successfully, the duplicate of these data is deleted from buffer memory.
Step 706:RN puts it in the PDCP buffer memory after receiving the data of DeNB transmission, carries the time that this packet arrives DeNB before this in this packet.
Step 707:RN calculates the time delay D T ' on the Un interface according to the time of the arrival DeNB that carries in current time and this packet.
Step 708:RN obtains the passed time D T of this section according to default DT and above-mentioned DT ' "=DT-DT '.
Step 709: as DT "＜0 the time, show that the time that consumes on the Un interface is too many, can not satisfy professional QoS demand, RN will abandon this bag.
Step 710: as DT " overtime after, if data also in the PDCP buffer memory, do not send successfully, then RN abandons these data.
Step 711: when at DT " during, RN successfully sends to UE with these data, then after sending successfully, the duplicate of these data is deleted from buffer memory.
Present embodiment calculates by the actual conditions to data, and the data that make normal process have QoS to guarantee abandon the data that do not have QoS to guarantee, can exist under the situation of RN, continues to provide the QoS of whole radio bearer to guarantee.Present embodiment is at the fixing qos parameter of each section configuration, but obtains the passed qos parameter of this section according to data in the actual transmissions situation of the preceding paragraph, can improve flexibility.
Fig. 8 is the method flow schematic diagram of eighth embodiment of the invention, comprising:
Step 801: following behavior example, configuration time delay D T in DeNB, this DT represents the time delay on the whole radio bearer.Be understandable that, when being up, need in UE, dispose this DT.
Step 802: when data arrived DeNB, DeNB put into the PDCP buffer memory with these data, and was this data startup DT.
Step 803: as the ACK that receives the RN feedback at DT in the time, then be discarded in the duplicate of cached data packet among the PDCP.
Wherein, ACK represents that UE successfully receives these data, after UE successfully receives the data that DeNB sends, by RLC status report notice RN, after RN receives the status report of UE, can pass through PDCP status report or medium access control (Media Access Control, MAC) unit, notice DeNB.
Step 804: when DT in the time these data still in the PDCP buffer memory, be not sent out success, then delete these data.
Step 805: but when DT in the time these data be sent out the ACK that does not receive that RN sends, then can send a notification message to RN, indication RN is with this data deletion.
This notification message can send to RN by MAC unit or PDCP status report, and the priority of other data of priority ratio of this notification message wants high, with guarantee as far as possible this notification message promptly and accurately send to RN.
Step 806: after RN receives this notification message, if this packet has been sent to UE, then ignore this notification message.
Step 807: after RN received this notification message, this packet was not sent to UE, then abandoned this packet.
Present embodiment calculates by the actual conditions to data, and the data that make normal process have QoS to guarantee abandon the data that do not have QoS to guarantee, can exist under the situation of RN, continues to provide the QoS of whole radio bearer to guarantee.Present embodiment need not at each intermediate node configuration qos parameter, but directly handles according to the actual transmissions situation of data on whole radio bearer, can improve flexibility.
Fig. 9 is the method flow schematic diagram of setting up carrying in the embodiment of the invention, comprising:
Qos parameter on the whole radio bearer that step 901:DeNB issues according to core net and channel condition and the transmission quality of Uu and/or Un interface, qos parameter on the whole radio bearer is divided into first qos parameter and second qos parameter, wherein, first qos parameter is the qos parameter of Un interface, and second qos parameter is that the qos parameter on the whole radio bearer deducts first qos parameter qos parameter afterwards.
Wherein, the qos parameter on the whole radio bearer that core net issues can be directly to send to DeNB, and afterwards, DeNB carries out the division of qos parameter; Also can be that core net sends to RN with the qos parameter on the whole radio bearer, send to DeNB by the qos parameter of RN on again will this whole radio bearer afterwards, be carried out the division of qos parameter by DeNB.
Step 902:DeNB determines that according to first qos parameter wireless parameter of Un interface disposes, and finishes the carrying of Un interface and sets up.
Step 903: if RN can resolve qos parameter, then DeNB sends to RN with second qos parameter.
Step 904:RN finishes qos parameter to the mapping of wireless parameter according to second qos parameter that DeNB sends, and finishes the carrying of Uu interface and sets up.
Step 905: if RN can not resolve qos parameter, then DeNB obtains the wireless parameter of the second qos parameter correspondence, and this wireless parameter is sent to RN.
