In the embodiment of the present application, scheduling entity, in each dispatching cycle, all can carry out taking turns wireless resource scheduling for the scheduling set of its correspondence, general, and described dispatching cycle can be the length of a radio frames, namely 10 milliseconds.Can in advance according to AP and UE in scheduling set, this scheduling set is divided into multiple transmission group, wherein, bind together the UE of shared SRES, and the AP of correspondence is divided in same transmission group, the transmission mode of AP with UE in each transmission group is identical, and the UE in different transmission groups is not identical, and the AP in different transmission groups may be identical.
Further, for scheduling set, after this scheduling set is divided into multiple transmission group, namely the relevant information of UE and AP in each transmission group can be obtained, and the dispatching priority of each transmission group can be obtained, wherein, described dispatching priority can be in advance for transmission group is arranged, and also can be the dispatching priority DBMS along using at the end of the dispatching cycle.Scheduling entity is follow-up can carry out wireless resource scheduling according to the dispatching priority of each transmission group.
S102: according to the dispatching priority of each transmission group is the user equipment allocation scheduling resource comprised in each transmission group.
In the embodiment of the present application, within each dispatching cycle, scheduling entity can according to the dispatching priority of each transmission group of scheduling set, for the UE comprised in each transmission group distributes SRES, wherein, the transmission group that dispatching priority is high is preferentially assigned to corresponding SRES, and obviously, the SRES distributing to transmission group should be the SRES that the AP in this transmission group has.
S103: according to scheduling resource allocation result, upgrades the dispatching priority of each transmission group.
In wireless resource scheduling process, the dispatching priority of each transmission group can be updated according to setting strategy.In the embodiment of the present application, can after the SRES often distributing setting quantity or setting grouping, just the dispatching priority of each transmission group is once upgraded respectively, the dispatching priority distributing the transmission group obtaining SRES is reduced, improve not yet distributing the dispatching priority obtaining the transmission group of SRES simultaneously, similar, also can reduce distributing the dispatching priority obtaining the transmission group of more SRES, improve distributing the dispatching priority obtaining the transmission group of less SRES simultaneously, thus, upper once distribute SRES time, can to distributing the UE priority allocation SRES obtained in the transmission group of less SRES.
Pass through said method, for scheduling set, because the scheduling entity of this scheduling set is in each dispatching cycle, can according to the SRES allocation result occurred, in time the dispatching priority of each transmission group of this scheduling set is upgraded respectively according to setting strategy, therefore, each UE dispatching distribution Radio Resource in scheduling set can be given liberally.
In the embodiment of the present application, in above-mentioned steps S102 and S103, according to the dispatching priority of each transmission group, for the user equipment allocation wireless resource block comprised in each transmission group, and according to wireless resource block allocation result, the dispatching priority of each transmission group is upgraded, specifically comprise: the SRES of each AP in scheduling set is numbered respectively, wherein, the numbering of the identical SRES of each AP is identical, then, for each numbering, according to the dispatching priority of each transmission group, by the SRES of this numbering, distribute to the UE comprised in each transmission group, and, after the SRES at every turn numbered for distributes, can according to the allocation result of the SRES for this numbering, the dispatching priority of each transmission group is once upgraded.
It should be noted that, SRES is identical refers to that the wireless resource block represented by SRES is identical, also be, the subcarrier comprised in wireless resource block represented by SRES is identical with code word, and in scheduling set, each SRES of same AP is not identical, but different AP can have identical SRES, therefore, when being numbered SRES, identical SRES numbering can be made identical.Integer 1 ~ tm_num can be used as the numbering of SRES, and wherein, tm_num is the total quantity of not identical SRES.
Within a dispatching cycle, the SRES of each numbering can distribute by scheduling entity successively respectively, and after all the SRES of numbering is assigned, this dispatching cycle terminates.The dispatching priority of each transmission group can represent by parameter, such as, can use SCH_Value Parametric Representation, in this case, time initial, the SCH_Value parameter of each transmission group all can be set to 0, be also, now the dispatching priority of each transmission group is identical, then, in each dispatching cycle after this, the SCH_Value parameter of each transmission group can be updated (again assignment), also namely, the dispatching priority of each transmission group can be updated.
Certainly, in actual applications, except adopting above-mentioned this dispatching priority update mode: after distributing for a SRES numbered, according to the allocation result of the SRES for this numbering, once can upgrade the dispatching priority of each transmission group.According to different setting strategies, other dispatching priority update mode can also be adopted, such as, can after distributing for the SRES of setting quantity or the SRES of setting numbering, or often through a setting-up time interval, the dispatching priority of each transmission group is once upgraded.
Further, in above-mentioned steps S102, according to the dispatching priority of each transmission group, by the SRES of this numbering, distribute to the UE comprised in each transmission group, specifically comprise: according to dispatching priority order from high to low, perform for each transmission group successively: the AP corresponding according to this transmission group, in the SRES of this numbering, by still unappropriated and belong to the SRES of AP corresponding to this transmission group, distributing to the UE in this transmission group, if do not exist still unappropriated and belong to the SRES of AP corresponding to this transmission group, is then that the UE in this transmission group distributes SRES failure.
Obviously, assuming that have identical AP in two transmission groups, then when distributing the SRES of certain numbering of AP, the transmission group that two transmission group medium priorities are higher can distribute the SRES of this numbering obtaining this AP, and then, because the SRES of this numbering of this AP is assigned with, therefore, for the transmission group that priority is lower, the SRES of this numbering of this AP can distribute failure.
In the embodiment of the present application, after joining the SRES of a numbering often to each transmission component, in scheduling set, some UE distributes the SRES obtaining this numbering, another part UE is unallocated to the SRES of this numbering, and one or more UE in each transmission group, can be had, therefore, follow-uply can distribute the result of SRES according to for the UE in each transmission group, upgrade the dispatching priority of each transmission group.In actual applications, the result of UE repeated dispensing SRES in the past can be considered, upgrade the dispatching priority of each transmission group, therefore, when initial, the dispatch list value indicative of this UE can be preset for each UE, wherein, the dispatch list value indicative of UE can be endowed specific implication, for representing successfully for this UE distributes the degree of SRES, concrete, the number of times successfully for this UE distribution SRES is more, degree then successfully for this UE distribution SRES is higher, and the dispatch list value indicative of this UE is larger.
Such as, the following implication of dispatch list value indicative of UE can be given: represent successfully for this UE distributes the number of times of SRES.Can by the dispatch list value indicative RR_Value Parametric Representation of UE, then after transmission group is assigned with SRES, the result can distributed according to SRES, upgrades the dispatch list value indicative of the UE in this transmission group, also namely, the RR_Value parameter of the UE in transmission group is upgraded.
Concrete, the RR_Value parameter of following formula to UE can be adopted to upgrade:
RR_value success＝RR_value+1；
RR_value fail＝RR_value+0；
Wherein, RR_value successfor when distributing SRES success for this UE, the RR_value parameter after renewal;
RR_value failfor when distributing SRES failure for this UE, the RR_value parameter after renewal.
It should be noted that, above formula based on precondition be: dispatch list value indicative, also, RR_Value parameter, represents successfully for corresponding UE distributes the number of times of SRES.
In actual applications, also other the implication of dispatch list value indicative of UE can be given, to reflect that this UE is become the degree of distribution of work SRES, when making as UE distribution SRES success, the dispatch list value indicative of this UE can increase in the updated, during for UE distribution SRES failure, dispatch list the value indicative constant or reduction in the updated of this UE.
Accordingly, above-mentionedly may be expressed as other forms to the formula that RR_Value parameter upgrades, include but not limited to following representation:
RR_value success＝a×RR_value+b；
RR_value fail＝c×RR_value+d；
Wherein, a, b, c, d are constant, RR_value success> RR_value, and RR_value fail≤ RR_value.
Further, in order to ensure the fairness of wireless resource scheduling, when the UE in transmission group is become the number of times of distribution of work SRES more, can the dispatching priority of this transmission group is updated to lower, thus the UE that can reduce in subsequent transmission group be become the probability of distribution of work SRES again.
Therefore, in above-mentioned steps S103, after the SRES at every turn numbered for distributes, according to the allocation result of the SRES for this numbering, the dispatching priority of each transmission group is once upgraded, specifically comprise: after the SRES at every turn numbered for distributes, dispatch list value indicative after upgrading according to each UE, the dispatching priority of each transmission group is once upgraded, wherein, for a transmission group undetermined, dispatch list value indicative sum after each UE comprised in this transmission group undetermined upgrades is larger, the dispatching priority of this transmission group undetermined is upgraded lower.
According to the above description, the formula for upgrading the dispatching priority of transmission group includes but not limited to following representation:
SCH _ Value ′ = m n + l × Σ i ∈ TM RR _ value ( i ) ;
Wherein, SCH_Value' represents that transmission group upgrades rear dispatching priority;
represent the RR_Value parameter sum of each UE in this transmission group;
M, n, l are the default constant being greater than 0, such as, can preset m=n=l=1.
Can find out, SCH_Value' with inversely proportional, thus dynamically can obtain the probability of SRES by balanced each UE.
According to above-mentioned explanation, figure 6 illustrates the detailed process of the wireless resource scheduling that the embodiment of the present application provides, specifically comprise the following steps:
S601: scheduling entity initialization.
Scheduling entity, in initialization procedure, first can be numbered and set up UE list, so that subsequent treatment each UE in scheduling set corresponding to this scheduling entity, such as, can be that each UE numbers with integer 1 ~ ue_num, wherein, ue_num can be the total quantity of UE in scheduling set.
Then, according to the transmission mode of UE each in scheduling set and each AP, scheduling set can be divided into multiple transmission group, wherein, UE and AP that transmission mode is identical belongs to same transmission group.Further, the each transmission group marked off also can also be numbered and set up transmission Groups List, so that subsequent treatment, such as, can be each transmission group # with integer 1 ~ tm_num, wherein, tm_num can be the total quantity of transmission group in scheduling set, obviously, tm_num<ue_num.
Can also be numbered each SRES in scheduling set with integer 1 ~ sres_num, wherein, the SRES of identical numbering is expressed as identical wireless resource block, and sres_num is the total quantity of the numbering of SRES.Certainly, in actual applications, can not be just also SRES numbering when scheduling entity initialization, but be SRES numbering again in follow-up scheduling process.
S602: judge whether the SRES of each AP in scheduling set all distributes, if so, then performs step S603, otherwise, perform step S604.
S603: terminate this wireless resource scheduling process.
S604: the numbering choosing the SRES that is not yet assigned with.
S605: according to the dispatching priority of each transmission group, according to dispatching priority from height to low order, sorts to each transmission group, and starts to travel through each transmission group to distribute the SRES of this numbering.
S606: judge whether each transmission group has traveled through, if so, then performs step S607, otherwise, perform step S608.
S607: according to the dispatch list value indicative of the UE in each transmission group, upgrades the dispatching priority of each transmission group, then performs step S602.
S608: the next one transmission group choosing current transmission group.
S609: for the transmission component chosen joins the SRES of this numbering.
S610: judge whether SRES is allocated successfully, if so, then performs step S611, otherwise performs step S612.
S611: be allocated successfully corresponding more new formula according to SRES, upgrade the dispatch list value indicative of each UE in this transmission group, then performs step S606.
S612: distribute unsuccessfully corresponding more new formula according to SRES, upgrade the dispatch list value indicative of each UE in this transmission group, then performs step S606.
In addition, it should be noted that, under some application scenarios, for each UE, also the multiple Business Streams comprised allocation schedule resource respectively can be given in this UE, then in this case, a dispatch list value indicative can be safeguarded respectively for each Business Stream on UE, accordingly, when upgrading the dispatching priority of transmission group, according to the dispatch list value indicative of multiple Business Streams of the UE in this transmission group, the dispatching priority of this transmission group can be upgraded, thus the fairness of wireless resource scheduling can be ensured.
