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 only 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 is obtained under the creative work prerequisite.
The method that one embodiment of the present of invention provide a kind of wireless carrying internal data to send, this radio bearer RB (Radio Bearer) can be by being used at UE and UTRAN (UMTS TerrestrialRadio Access Network that layer 2 provides, UMTS Terrestrial radio access network) transmission channel of service data transmission between, wherein UTRAN is by one group of RNS (RNS, RadioNetwork Subsystem) composition that is connected to core net by the Iu interface.(Radio NetworkController RNC) forms with one or more base stations a RNS by a radio network controller.The base station is connected to RNC by Iub interface; As shown in Figure 1, comprising:
101, RNC (Radio Network Controller, radio network controller) determines the delay sensitive priority of described business datum when receiving business datum.In the embodiment of the invention two delay sensitive priority can be set at least, for example, high delay sensitive priority and low delay sensitive priority.The business datum high to delay requirement can its delay sensitive priority be set to high delay sensitive priority.
For example, the described delay sensitive priority of determining described business datum can comprise: the delay sensitive type of obtaining described business datum; According to the described delay sensitive type of obtaining, and the corresponding relation of the delay sensitive priority of delay sensitive type and business datum, determine the delay sensitive priority of described business datum.Wherein, corresponding at least two delay sensitive priority that the embodiment of the invention is provided with, the delay sensitive type of business datum should comprise types different in two at least, so that business datum is carried out the differentiation of delay sensitive priority.
102, described RNC rearranges the service data unit (SDU, Service Data Unit) of described business datum according to scheduling strategy, and described scheduling strategy can be provided with according to the delay sensitive priority of business datum at least.
For example, described RNC according to scheduling strategy rearrange described business datum service data unit can for, described RNC can rearrange the service data unit of described business datum according to the delay sensitive priority of described business datum; When the service data unit of the business datum that will receive deposits in earlier in the priority buffer queue, when accessing when to be sent again and sending, described RNC also can be according to the delay sensitive priority of described business datum or the service data unit that rearranges described business datum according to the delay sensitive priority and the sent data volume in the buffer queue of described business datum; This scheduling strategy can comprise dispatching algorithm and every kind of used scheduling parameter of algorithm.This dispatching algorithm can adopt the dispatching algorithm of PQ (Priority Queue, priority query), RR (Round Robin, round-robin scheduling) or WRR (Weighted Round Robin, the round-robin scheduling that cum rights is heavy).Wherein:
PQ can be embodied as the data transmit queue a kind of priority query with the priority insertion mechanism.This data transmit queue can be according to the situation of data cached priority in this formation, and the priority of the business datum SDU that receives, determines the insertion position of described SDU, after the level that this insertion position is that All factors being equal, preference will be give to, before the lower priority; And with described SDU insertion data transmit queue.Used scheduling parameter can be delay sensitive priority progression in this dispatching algorithm, and this delay sensitive priority progression is that the user is configurable, comprises two different delay sensitive priority numbers at least.
RR is the dispatching algorithm that can realize the SDU scheduling of business datum in a plurality of priority buffer queues.Radio network controller directly is not inserted into the data transmit queue after receiving the SDU of business datum, but earlier described SDU is put into corresponding delay sensitive priority corresponding priorities buffer queue, when sending data, again according to the delay sensitive priority order from high to low of described SDU, from each priority buffer queue, obtain SDU, and send.Used scheduling parameter can be delay sensitive priority progression in this algorithm, this delay sensitive priority progression is that the user is configurable, at least comprise two different delay sensitive priority numbers, and with the number of described delay sensitive priority corresponding priorities buffer queue also be that the user is configurable.
WRR is improved a kind of dispatching algorithm on the RR basis, and it can be provided with a scheduling proportionality coefficient to each priority cache level formation.In certain dispatching cycle, the business datum that can send is distributed to each priority buffer queue according to the scheduling proportionality coefficient, and described business datum of distributing according to the scheduling proportionality coefficient is the current data volume that sends of each priority buffer queue.When sending data, preferentially maybe can send the preferential scheduling tendency of business datum amount according to priority again, from each priority buffer queue, fetch data, send.The priority here preferentially refers to, as long as the sent data volume of higher priority is just fetched data from the higher priority buffer queue greater than 0; All from the priority buffer queue that can send the data volume maximum, fetch data but the transmission data volume preferentially is meant at every turn, when the sent data volume in each buffer queue equates, preferentially from the high buffer queue of priority, fetch data.When the current data volume that sends in all priority buffer queues all smaller or equal to 0 the time, enter next round dispatching cycle, redistribute and can send data volume.The used priority progression of this algorithm, scheduling proportionality coefficient and corresponding priority level preferentially maybe can send the preferential scheduling parameter such as scheduling tendency of data volume, all are that the user is configurable, and this priority progression comprises two different delay sensitive priority numbers at least.
In the process of implementing the embodiment of the invention, specifically adopt which kind of dispatching algorithm, reach the corresponding scheduling parameter of dispatching algorithm that adopts and how to be provided with, the user can select according to real needs; For example, when the user knows that the data volume of the business datum that delay sensitive priority is high is very little, delay sensitive priority as browsing page is high delay sensitive priority, but the user can adopt the scheduling strategy of PQ or RR dispatching algorithm when carrying out browsing page professional once in a while; When the user knows that the data volume of the business datum that delay sensitive priority is high is very big, be high delay sensitive priority as the delay sensitive priority of Online Video, and the user often carry out Online Video when professional, can adopt the scheduling strategy of WRR dispatching algorithm.But the embodiment of the invention does not limit this, and the user can be according to the delay sensitive priority of different business when implementing the embodiment of the invention, and different concrete application is specifically selected.
103, the service data unit of described RNC after with described rearranging sends.
In the embodiment of the invention, in radio bearer after RNC receives business datum, determine the delay sensitive priority of described business datum earlier, and then the scheduling strategy that is provided with according to the delay sensitive priority of foundation business datum, the service data unit of described business datum is rearranged and sends, the service data unit of the high business datum of delay sensitive priority sent earlier, thereby reduced the propagation delay time of the high business datum of delay sensitive type, promoted user's impression.
The method that an alternative embodiment of the invention provides a kind of wireless carrying internal data to send.After RNC receives business datum, according to scheduling strategy rearrange the SDU of described business datum and the process that sends in, RNC can be after receiving described SDU, can directly described SDU be rearranged and put into according to scheduling strategy in the data transmit queue, when sending business datum, will arrange good SDU and send; Also can according to delay sensitive priority with described SDU be temporarily stored in earlier with this delay sensitive priority corresponding cache formation in, when sending business datum, the SDU that dispatches in each buffer queue according to scheduling strategy puts into data transmit queue and transmission again, and the embodiment of the invention does not limit this.The embodiment of the invention is dispatched described SDU again and is sent as example when sending business datum to keep in the SDU of the business datum that receives earlier, specifically sets forth the method that wireless carrying internal data sends, and as shown in Figure 2, this method comprises:
When 201, carrying out the transmission of business datum in RB, RNC receives business datum, the data that described business datum can send for the upper strata of data link layer, and this upper strata can be for network layer and with the upper strata.
202, described RNC judges the delay sensitive type that whether comprises described business datum in the described business datum when receiving business datum; If judge in the described business datum to comprise described delay sensitive type, then execution in step 203; If judge in the described business datum not comprise described delay sensitive type, then execution in step 204.
Wherein, the delay sensitive type of described business datum, can be by GGSN (Gateway GPRS SupportNode, Gateway GPRS Support Node) obtains in the following manner, for example, portion discerns the protocol header and the message content of described business datum message within it, identify the protocol type of business datum, and obtain QoS (the Quality of Service of this business datum application layer according to the protocol type of this business datum, service quality) grade, QoS grade according to the described business datum application layer of obtaining, and the corresponding relation of the delay sensitive type of the QoS grade of business datum application layer and business datum, determine the delay sensitive type of described business datum, and described delay sensitive type is carried in the business datum issues, therefore after described RNC is receiving described business datum, need carry out corresponding operation according to the delay sensitive type that whether comprises described business datum in the described business datum.
203, described RNC directly receives the delay sensitive type of carrying in the described business datum, and execution in step 205.
204, described RNC discerns the delay sensitive type of obtaining described business datum to the business datum that receives, and execution in step 205.
For example, the described business datum that receives is discerned obtained described delay sensitive type, can comprise: the described business datum that receives is resolved the protocol type that obtains described business datum; Obtain the QoS grade of described business datum application layer according to the described protocol type that obtains; According to the QoS grade of the described application layer of obtaining, and the corresponding relation of the delay sensitive type of the QoS grade of business datum application layer and business datum, determine the delay sensitive type of described business datum.In implementing the process of the embodiment of the invention, the delay sensitive type of business datum, the user can specifically be provided with according to demand, and with the corresponding relation preservation of the QoS grade level of this kind delay sensitive type and business datum application layer; When needs obtain the delay sensitive type of business datum, QoS grade according to described business datum application layer, and the corresponding relation of the QoS grade of described business datum application layer and delay sensitive type, just can obtain the delay sensitive type of described business datum.
205, described RNC is according to the described delay sensitive type of obtaining, and the corresponding relation of delay sensitive type and the responsive priority of service delay, determines the delay sensitive priority of described business datum.
For example, when implementing the embodiment of the invention, the user can be the different delay sensitive priority of business setting of the responsive type of different delay, and the corresponding relation of this kind delay sensitive type and delay sensitive priority is preserved; Obtained the delay sensitive type of described business datum as RNC after,, determine the delay sensitive priority of described business datum, so that rearrange the SDU of described business datum according to scheduling strategy according to the corresponding relation of preserving in advance.Wherein, described delay sensitive priority can comprise at least two kinds of delay sensitive priority of setting, distinguishes so that will have the SUD of the business datum of the responsive priority of different delay.
206, described RNC puts into and the formation of described delay sensitive priority corresponding cache according to the delay sensitive priority of the described business datum SDU with described business datum.
Wherein, because the embodiment of the invention has been carried out the division of delay sensitive priority to the business datum that receives, in RNC, be provided with accordingly and the formation of described delay sensitive priority corresponding cache, so that the SDU of the business datum of the responsive priority of different delay is put into different buffer queues.
The embodiment of the invention is example so that 3 of 3 delay sensitive priority and relative set to be set with this delay sensitive priority corresponding cache formation, the concrete elaboration according to described delay sensitive priority put into scheme with the formation of described delay sensitive priority corresponding cache with the SDU of described business datum, as shown in Figure 3, the business datum that receives is carried out after delay sensitive priority determines, when if the delay sensitive priority of the business datum that receives is high priority, the SDU of this business datum is put into the formation of high priority corresponding cache; When if the delay sensitive priority of the business datum that receives is medium priority, the SDU of this business datum is put into the formation of medium priority corresponding cache; When if the delay sensitive priority of the business datum that receives is low priority, the SDU of this business datum is put into the formation of low priority corresponding cache.
207, rearrange according to the SDU in the formation of the responsive priority corresponding cache of described scheduling strategy scheduling different delay, and with the SDU that dispatches out, described scheduling strategy can be provided with according to the delay sensitive priority of business datum at least.
For example, described according to the SDU in the formation of the responsive priority corresponding cache of described scheduling strategy scheduling different delay, and the SDU that dispatches out rearranged, can be for according to the delay sensitive priority of described business datum or according to the delay sensitive priority of described business datum and the sent data volume in the described buffer queue, dispatch the service data unit in the corresponding buffer queue of the responsive priority of different delay, and the service data unit of dispatching out is rearranged; This scheduling strategy can comprise dispatching algorithm and every kind of used scheduling parameter of algorithm.This dispatching algorithm can adopt the dispatching algorithm of RR (Round Robin, round-robin scheduling) or WRR (WeightedRound Robin, the round-robin scheduling that cum rights is heavy).Wherein:
RR is the dispatching algorithm that can realize the SDU scheduling of business datum in a plurality of priority buffer queues.Radio network controller directly is not inserted into the data transmit queue after receiving the SDU of business datum, but earlier described SDU is put into corresponding delay sensitive priority corresponding priorities buffer queue, when sending data, again according to the delay sensitive priority order from high to low of described SDU, from each priority buffer queue, obtain SDU, and send.Used scheduling parameter can be delay sensitive priority progression in this algorithm, this delay sensitive priority progression is that the user is configurable, at least comprise two different delay sensitive priority numbers, and with the number of described delay sensitive priority corresponding priorities buffer queue also be that the user is configurable.
WRR is improved a kind of dispatching algorithm on the RR basis, and it can be provided with a scheduling proportionality coefficient to each priority cache level formation.In certain dispatching cycle, the business datum that can send is distributed to each priority buffer queue according to the scheduling proportionality coefficient, and described business datum of distributing according to the scheduling proportionality coefficient is the current data volume that sends of each priority buffer queue.When sending data, preferentially maybe can send the preferential scheduling tendency of business datum amount according to priority again, from each priority buffer queue, fetch data, send.The priority here preferentially refers to, as long as the sent data volume of higher priority is just fetched data from the higher priority buffer queue greater than 0; All from the priority buffer queue that can send the data volume maximum, fetch data but the transmission data volume preferentially is meant at every turn, when the sent data volume in each buffer queue equates, preferentially from the high buffer queue of priority, fetch data.When the current data volume that sends in all priority buffer queues all smaller or equal to 0 the time, enter next round dispatching cycle, redistribute and can send data volume.The used priority progression of this algorithm, scheduling proportionality coefficient and corresponding priority level preferentially maybe can send the preferential scheduling parameter such as scheduling tendency of data volume, all are that the user is configurable, and this priority progression comprises two different delay sensitive priority numbers at least.
In the process of implementing the embodiment of the invention, specifically adopt which kind of dispatching algorithm, reach the corresponding scheduling parameter of dispatching algorithm that adopts and how to be provided with, the user can select according to real needs; For example, when the user knows that the data volume of the business datum that delay sensitive priority is high is very little, delay sensitive priority as browsing page is high delay sensitive priority, but the user can adopt the scheduling strategy of RR dispatching algorithm when carrying out browsing page professional once in a while; When the user knows that the data volume of the business datum that delay sensitive priority is high is very big, be high delay sensitive priority as the delay sensitive priority of Online Video, and the user often carry out Online Video when professional, can adopt the scheduling strategy of WRR dispatching algorithm.But the embodiment of the invention does not limit this, and the user can be according to the delay sensitive priority of different business when implementing the embodiment of the invention, and different concrete application is specifically selected.Scheduling strategy with the WRR dispatching algorithm in the embodiment of the invention is an example, puts into the data transmit queue after the SDU in each buffer queue is dispatched out and rearranges, as shown in Figure 3.
