Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, the embodiment of the present invention provides a kind of resource regulating method, is applied to LTE system, and the method comprises:
101, ARP is divided into n priority groups, n >=2, each priority groups comprises multiple ARP, different priorities group has different group priority, any ARP in first priority groups is higher than any ARP in the second priority groups, and the group priority of the first priority groups is higher than the group priority of the second priority groups.
Wherein, each carrying has ARP parameter, and ARP parameter comprises ARP value, preempt and is preempted mark, and wherein ARP value is used for representing the height of ARP of carrying, preempt is used for representing that whether carrying is for seizing carrying, is preempted mark and is used for representing that whether carrying is for being preempted carrying.Such as, ARP value can be from 1 to 15, and ARP is higher for the lower expression of ARP value.
Such as, these 3 priority groups of A, B, C are divided into by ARP when n is 3, A comprises 5 ARPs of ARP value from 1 to 5, B comprises 5 ARPs of ARP value from 6 to 10, it is 2 that C comprises ARP value from the group priority value that the group priority value of 5 ARP, the A of 11 to 15 is 1, B, the group priority value of C is 3, and group priority value lower expression group priority is higher.
It should be noted that the ARP quantity that the value of n and each priority groups comprise can be determined according to actual conditions.
102, arrange n and seize group, seize a group corresponding n priority groups respectively for n, seize group corresponding n group priority respectively to make n, each seizing organizes corresponding multiple ARP, will wait for that the carrying of seizing of connecting system is subdivided into seizing in group of corresponding A RP according to the ARP of carrying.
Wherein, seizing the preempt be carried as in the ARP parameter of carrying is the carrying of seizing.
It should be noted that, in this step, the value of n is consistent with the value of n in step 101.
Such as, when n value is same as described above be 3 time, arrange 3 and seize group A ', B ', C ', these 3 seize group respectively corresponding above-mentioned in 3 priority groups A, B, C, group corresponding 3 group priority are respectively seized to make these 3,5 ARPs of 5 ARP, the C of 6 to 10 ' the corresponding A RP value from ' corresponding A RP value from 11 to 15 thus A ' corresponding A RP value is from 5 ARP, the B of 1 to 5.When the ARP value seizing carrying waiting for connecting system is 3, this carrying is divided in A ', when the ARP value seizing carrying waiting for connecting system is 12, this carrying is divided in C '.
It should be noted that, each to seize in group all may not or have multiple wait connecting system seize carrying.
103, arrange n and be preempted group, n is preempted a group corresponding n priority groups respectively, is preempted group corresponding n group priority respectively to make n, eachly be preempted the corresponding multiple ARP of group, the carrying that is preempted of connecting system is subdivided into being preempted in group of corresponding A RP by the ARP according to carrying.
Wherein, the carrying being preempted in the ARP parameter being carried as carrying and being labeled as and being preempted is preempted.
It should be noted that, in this step, the value of n is consistent with the value of n in step 101.
Such as, when n value is same as described above be 3 time, arrange 3 and be preempted group A ", B ", C "; these 3 be preempted group respectively corresponding above-mentioned in 3 priority groups A, B, C; be preempted group corresponding 3 group priority respectively to make these 3; thus A " 5 ARP, the Bs of corresponding A RP value from 1 to 5 " 5 ARP, the Cs of corresponding A RP value from 6 to 10 " 5 ARPs of corresponding A RP value from 11 to 15.When the ARP value being preempted carrying of connecting system is 5, this carrying is divided into A " in, when the ARP value seizing carrying of connecting system is 8, this carrying is divided into B " in.
It should be noted that, each to seize in group all may not or have multiple connecting system be preempted carrying.
104, seize group each and be preempted in group each, parameter z is seized for this carrying is arranged according to the resource occupation amount of each carrying and ARP, seize group each and be preempted in group each, for the carrying that ARP is identical, seize parameter z and the positive correlation of resource occupation amount, for the carrying that resource occupation amount is identical, seize parameter z and ARP negative correlation.
Wherein, for the carrying that ARP is identical, seize parameter z and refer to that, for the identical carrying of ARP, the resource occupation amount of carrying is more, and z is larger with the positive correlation of resource occupation amount, the resource occupation amount of carrying is less, and z is less.For the carrying that resource occupation amount is identical, seize parameter z and refer to that the ARP of carrying is higher, and z is less for the identical carrying of resource occupation amount with the priority negative correlation of carrying, the ARP of carrying is lower, and z is larger.
105, seize carrying for each preempting priority is set, seize in group each, what carry seizes parameter z and preempting priority negative correlation, for each be preempted carrying setting be preempted priority, be preempted in group each, carrying seize parameter z be preempted priority positive correlation.
It should be noted that, more high more advanced the robbing of preempting priority of seizing carrying accounts for operation, and the priority that is preempted being preempted carrying is got over Gao Yuexian and is preempted.
Wherein, seize in group each, seize parameter z and the preempting priority negative correlation of carrying refer to that to seize parameter z less, and preempting priority is higher, and seize parameter z on the contrary larger, preempting priority is lower.Be preempted in group each, seizing parameter z and being preempted priority positive correlation and referring to that to seize parameter z larger of carrying, is preempted priority higher, seizes parameter z on the contrary less, be preempted priority lower.
Such as, if there are two carryings in a carrying group, these two carryings are respectively carrying 1, carrying 2.If the parameter z that seizes of carrying 1 is 1, the parameter z that seizes of carrying 2 is 2, when this carrying group is for seizing group, then carries the preempting priority of 1 higher than the preempting priority of carrying 2, when this carrying group is for being preempted group, then the priority that is preempted carrying 2 is preempted priority higher than carrying 1.
106, all carryings of seizing of seizing in group are sorted.
Concrete, all carryings of seizing of seizing in group are carried out sequence and comprised: sorting to seizing group according to group priority order from high to low, seizing in group each, sorting according to preempting priority order from high to low to seizing carrying.
107, seize seizing in group and carry the result that sorts according to all and make successively eachly to seize carrying and seize operation.
Concrete, make eachly to seize carrying and carry out seizing operation and comprise:
The carrying that is preempted in dismountable group is sorted, dismountable group is seize carrying corresponding group all of priority be preempted group lower than this, carry to being preempted in dismountable group the process sorted to comprise: to all groups that are preempted in dismountable group according to the order sequence from low to high of group priority, being preempted in group dismountable group each, sorting according to being preempted priority order from high to low to being preempted carrying;
Remove successively be preempted carrying according to carrying the result that sorts to being preempted in dismountable group, until system spare resource meets the stock number that this seizes carrying needs, system spare Resourse Distribute is seized carrying to this, or until all in dismountable group are preempted after carrying all removes, system spare resource still cannot meet the stock number that this seizes carrying needs, this is seized the data packet discarding of carrying.Or, if after judging that all in dismountable group being preempted carrying all removes, whether system spare resource meets the stock number that this seizes carrying needs, if, then remove successively be preempted carrying according to carrying the result that sorts to being preempted in dismountable group, until system spare resource meets the stock number that this seizes carrying needs, system spare Resourse Distribute is seized carrying to this, if not, then this is seized the data packet discarding of carrying.
The resource regulating method that the embodiment of the present invention provides, compared with carrying out dismounting carrying with the ARP that in prior art, only foundation carries, the present invention is by dividing into groups for seizing to carry and be preempted to carry, and seize in group the preempting priority of seizing carrying according to the ARP of carrying and the definition of resource occupation amount and be preempted in group the priority be preempted being preempted carrying, then according to the preempting priority of definition be preempted priority and carry out seizing operation, avoid in prior art and carry out in the process seized in order to some to remove the phenomenon of too much carrying compared with the carrying of consumption of natural resource by means of only ARP, achieve while resource is seized, improve Consumer's Experience on the whole.
Further alternative, arrange n in a step 102 and seize group, seize a group corresponding n priority groups respectively for n, group corresponding n group priority is respectively seized to make n, each seizing organizes corresponding multiple ARP, seize before carrying is subdivided into the process seizing in group of corresponding A RP according to the ARP of carrying by what wait for connecting system, this resource regulating method also comprises:
By from 0 one continuous time section be divided into multiple sub-time period, the different sub-time periods has different Time priorities, any time in first sub-time period is less than any time in the second sub-time period, the Time priority of the first sub-time period, higher than the Time priority of the second sub-time period, will wait for that this carrying is divided in the corresponding sub-time period by the moment that carrying enters waiting list according to this carrying of seizing of connecting system.
Arrange n in a step 102 and seize group, seize a group corresponding n priority groups respectively for n, to make n seize group corresponding n group priority respectively, eachly seize the corresponding multiple ARP of group, will wait for that seizing of connecting system carries the process seized in group being subdivided into corresponding A RP and be according to the ARP of carrying:
In each sub-time period, arrange n seize group, seize a group corresponding n priority groups respectively for n, group corresponding n group priority is respectively seized to make n, eachly seize the corresponding multiple ARP of group, the carrying of seizing of medium for this sub-time period system to be accessed is subdivided into seizing in group of corresponding A RP in this time group by the ARP according to carrying.
Sorting to seizing group according to group priority order from high to low in step 106, seizing in group each, to seizing the process that carrying sorts according to preempting priority order being from high to low:
According to Time priority order from high to low, all sub-time periods are sorted, in each sub-time period, sorting to seizing group according to group priority order from high to low, seizing in group each, sorting according to preempting priority order from high to low to seizing carrying.
It should be noted that: do not occur simultaneously between each sub-time period, and the duration of each sub-time period is not necessarily identical.
Son of illustrating below illustrates the method: suppose section continuous time to 00:00:20 from 00:00:00 to be divided into 3 sub-time periods.First sub-time period is 00:00:00-00:00:05, and second sub-time period is 00:00:06-00:00:10, and the 3rd sub-time period is 00:00:11-00:00:20.Because any time in the first sub-time period is all less than any time in other two sub-time periods, therefore the Time priority of first sub-time period is higher than the Time priority of other two sub-time periods.When wait for connecting system to seize moment that carrying enters waiting list be 00:00:07 time this carrying is divided in second sub-time period, when wait for connecting system to seize moment that carrying enters into waiting list be 00:00:15 time, this carrying is divided in the 3rd sub-time period.Be understandable that, the moment of seizing in sub-time period corresponding to carrying more early entering waiting list is less.To will also be appreciated that in each sub-time period all may not or have multiple wait connecting system seize carrying.
Above-mentioned only for 00:00:00 start to 00:00:20 continuous time to division the sub-time period be described, in practical situations both, applicable section continuous time can be selected according to actual conditions, and the number of the sub-time period of setting division and the duration of each sub-time period.
Be understandable that, to wait for that this carrying is divided in the corresponding sub-time period by the moment that carrying enters waiting list according to this carrying of seizing of connecting system, achieve more advanced the robbing of carrying of seizing more early entering waiting list and account for operation, to avoid in prior art and only carry out seizing according to the ARP seizing carrying and the carrying of seizing that causes ARP low is in the phenomenon waiting for race to control state always.
Further alternative, seize group each and be preempted in group each at step 104, seizing parameter z according to the resource occupation amount of each carrying and ARP for this carrying is arranged and comprise:
Seize group each and be preempted in group each, according to resource occupation amount order from less to more carrying sorted and obtain the first ranking results, for each carrying arranges resource occupation sequence number x, seize group each and be preempted in group each, the resource occupation amount of carrying and resource occupation sequence number x positive correlation.
Seize group each and be preempted in group each, according to ARP order from high to low carrying sorted and obtain the second ranking results, for each carrying arranges ARP sequence number y, seize group each and be preempted in group each, ARP and the ARP sequence number y negative correlation of carrying.
The resource occupation sequence number x carried in first ranking results equals the ARP sequence number y in the second ranking results, identical sorting position carried.
Seize parameter z=a × x+ (1-a) × y, 0 < a < 1.It should be noted that, resource occupation sequence number x and ARP sequence number y can be the consecution natural number from 1.
Be all that consecution natural number from 1 is described the method for resource occupation sequence number x and ARP sequence number y below.
If there are 4 carryings in a carrying group, these 4 bearing identifications carried, bearing resource occupancy and carrying ARP values can refer to table 1:
| Bearing identification | Bearing resource occupancy | Carrying ARP value |
| Carrying 1 | 40 | 1 |
| Carrying 2 | 50 | 2 |
| Carrying 3 | 20 | 3 |
| Carrying 4 | 10 | 4 |
Table 1
In table 1 to the setting of numerical value corresponding to bearing resource occupancy parameter only for illustrating how many relations of each bearing resource occupancy, may be different from bearing resource occupancy in the middle of reality.Bearing identification is for identifying different carryings in Table 1, and bearing identification can be numeral, and table 1 is only described the method for numeral.
According to resource occupation amount order from less to more, carrying is sorted in this carrying group, can refer to table 2:
| Bearing identification | Bearing resource occupancy | Carrying ARP value | x |
| Carrying 4 | 10 | 4 | 1 |
| Carrying 3 | 20 | 3 | 2 |
| Carrying 1 | 40 | 1 | 3 |
| Carrying 2 | 50 | 2 | 4 |
Table 2
It should be noted that, for the same resource occupation sequence number of the bearing shared that resource occupation amount is identical.
After carrying being sorted according to carrying ARP order from high to low in this carrying group, can refer to table 3:
| Bearing identification | Bearing resource occupancy | Carrying ARP value | y |
| Carrying 1 | 40 | 1 | 1 |
| Carrying 2 | 50 | 2 | 2 |
| Carrying 3 | 20 | 3 | 3 |
| Carrying 4 | 10 | 4 | 4 |
Table 3
It should be noted that, for the same ARP sequence number of bearing shared that carrying ARP is identical.
Suppose that a equals 1/2, what carried by the resource occupation sequence number x in formula z=a × x+ (1-a) × y and table 2 and the ARP sequence number y in table 34 of calculating respectively in this carrying group seizes parameter z, and the result after calculating can refer to table 4:
| Bearing identification | Bearing resource occupancy | Carrying ARP value | z |
| Carrying 1 | 40 | 1 | 2 |
| Carrying 2 | 50 | 2 | 3 |
| Carrying 3 | 20 | 3 | 5/2 |
| Carrying 4 | 10 | 4 | 5/2 |
Table 4
Seize in group each, for seizing the identical carrying of parameter z, the ARP positive correlation of preempting priority and carrying.Being preempted in group each, for seizing the identical carrying of parameter z, being preempted the ARP negative correlation of priority and carrying.
When 4 in table 4 be carried as seize carrying time, owing to having introduced the preempting priority of carrying in step 105 and having seized parameter z negative correlation, therefore directly can find out that these 4 the preempting priorities orders seizing carrying are by table 4: carrying 1> carries 3> and carries 4> and carry 2, therefore seize and be carried on the order of carrying out when seizing operation and be for these 4: carrying 1> carries 3> and carries 4> carrying 2.And in prior art these 4 seize to be carried on and carry out order when seizing operation and only determined by the ARP carried, therefore seize and be carried on the order of carrying out when seizing operation and be for these 4: carrying 1> carries 2> and carries 3> carrying 4, as can be seen here, after parameter z is seized in setting, be carried on and carry out order when seizing operation with being carried in prior art compared with the order of carrying out when seizing operation and change.
Suppose that 4 in table 4 are carried as some carryings of seizing in group, suppose that existence one is preempted group, the parameter z that seizes that the bearing identification carried in this group, bearing resource occupancy are corresponding with carrying ARP value and this carrying can refer to table 5:
| Bearing identification | Bearing resource occupancy | Carrying ARP value | z |
| Carrying 1 | 40 | 5 | 2 |
| Carrying 2 | 50 | 6 | 3 |
| Carrying 3 | 20 | 7 | 5/2 |
| Carrying 4 | 10 | 8 | 5/2 |
Table 5
The computational methods seizing parameter z of each carrying are identical to each account form seizing parameter z carried with above-mentioned table 1 in table 5, specifically can refer to foregoing description, do not repeat one by one at this.
Owing to having introduced being preempted priority and seizing parameter z positive correlation of carrying in step 105, therefore directly can find out that these 4 priority orders that are preempted being preempted carrying are by table 5: carrying 2> carries 4> and carries 3> carrying 1, therefore these 4 orders that are preempted being preempted carrying are: carrying 2> carry 4> carry 3> carrying 1 and in prior art these 4 orders that are preempted being preempted carrying only determined by the ARP that carries, therefore these 4 orders that are preempted being preempted carrying are: carrying 4> carries 3> and carries 2> carrying 1, as can be seen here, after parameter z is seized in setting, carrying be preempted order with carry in prior art be preempted order compared with change.
Below for table 4 and table 5, the operation of seizing of seizing carrying in the present invention is described.
Because the ARP of arbitrarily carrying in table 4 is higher than the ARP of carrying arbitrarily in table 5, therefore seize the group priority of group in table 4 higher than the group priority being preempted group in table 5, so being preempted carrying and can being preempted in table 5.What preempting priority was the highest in table 4 seize carrying 1 starts to carry out seizing operation, the carrying 2 that is preempted being preempted priority in table 5 the highest is first removed, the resource residual amount being removed rear system due to the carrying 2 in table 5 meets the stock number carrying 1 needs in table 4, therefore without the need to removing other carrying in table 5, and only remove be preempted carrying according to the ARP of carrying in prior art, if be preempted carrying only comprise carrying in table 5, so need will carry 4 according to the order of ARP, carrying 3, carrying 2 is carried out removing to meet the stock number seizing carrying 1 needs, compared with prior art, the present invention seizes parameter z by arranging after considering the resource occupation amount of carrying and ARP, and then determine the preempting priority that carries and be preempted carrying be preempted priority, avoid in prior art and carry out in the process seized in order to some to remove the phenomenon of too much carrying compared with the carrying of consumption of natural resource by means of only ARP, achieve while resource is seized, improve Consumer's Experience on the whole.
