Embodiment
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.
One embodiment of the invention provides a kind of resource allocation methods, and as shown in Figure 1, the method comprises:
If the 101 GBR carryings being carried as non-emergent business to be allocated, be then this carrying Resources allocation to be allocated when being no more than GBR bearing resource total amount is no more than system spare available volume of resources simultaneously.
Wherein, GBR bearing resource total amount equals the product of GBR bearing resource ratio and system allowable resource amount, 0 < GBR bearing resource ratio < 1.
What deserves to be explained is, system allowable resource amount is the maximum wireless stock number that system can be used for distributing to EPS carrying, and this value should be less than or equal to whole amount of radio resources that system can provide.
102, when a × b1 > GBR bearing resource total amount, GBR bearing resource ratio is increased.
Wherein, if the GBR that a is Resources allocation carries stock number shared when reaching GBR speed, b1 > 1.GBR speed is the minimum guarantee speed of GBR carrying, and each GBR carries the restriction of the GBR speed having it exclusive, and making GBR carry the stock number consumed when reaching GBR speed is the minimum essential requirement amount of GBR carrying to resource.
It should be noted that, because GBR carrying is assigned to resource, so the GBR of Resources allocation carries the stock number taken and must be less than GBR bearing resource total amount, so make a be multiplied by coefficient b1 that one is greater than 1, a × b1 can reflect the primary demand amount of GBR carrying to resource, when GBR carrying is greater than GBR bearing resource total amount to the primary demand amount of resource, illustrate that GBR bearing resource total amount is very few, the current primary demand amount of GBR carrying to resource being assigned with resource can not be met, so GBR bearing resource ratio should be increased.
Wherein, b1 can be arranged as required, and it is too small that b1 is arranged, and will GBR bearing resource ratio be caused not easily to reach a larger value, makes GBR carry the enough resources of more difficult acquisition.
103, when a × b1≤GBR bearing resource total amount, and during c < GBR bearing resource total amount, GBR bearing resource ratio is reduced.
Wherein, if the GBR carrying that c is Resources allocation reaches MBR (Maximum Bit Rate, maximum bit rate) speed time shared stock number, MBR speed is the maximum guarantee speed of GBR carrying, each GBR carries the restriction of the MBR speed having it exclusive, and the stock number consumed when GBR carrying reaches MBR speed is a maximum demand of GBR carrying to resource.
It should be noted that, when GBR bearing resource total amount meets the primary demand amount of GBR carrying to resource, if shared stock number is less than GBR bearing resource total amount when the GBR carrying of Resources allocation reaches MBR speed, illustrate GBR bearing resource total amount meet GBR carrying to a maximum demand of resource after, also have surplus resources, now should reduce GBR bearing resource ratio.
104, when a × b1≤GBR bearing resource total amount, and during c > GBR bearing resource total amount, current GBR bearing resource ratio is kept.
Now, GBR bearing resource total amount meets the primary demand amount of GBR carrying to resource of Resources allocation, and GBR bearing resource total amount can be consumed when if the GBR carrying of Resources allocation all reaches MBR speed, illustrate that current GBR bearing resource ratio is reasonable, do not need to revise it.
What deserves to be explained is, for GBR bearing resource ratio will be revised after each carrying Resources allocation to be allocated, according to corrected GBR bearing resource ratio to next one carrying Resources allocation to be allocated, then resource ratio is again revised according to resource allocation result, the correction carrying out Resourse Distribute and GBR bearing resource ratio of circulation like this, embodiments of the invention are all assigned as example with first resource and are described.
The resource allocation methods that the embodiment of the present invention provides, GBR bearing resource ratio is set, when being no more than GBR bearing resource total amount and be no more than system spare available volume of resources for GBR to be allocated carries Resources allocation, dynamically increase according to resource allocation result or reduce GBR bearing resource ratio, make the GBR carrying being assigned with resource can get enough resources to reach GBR speed, if avoid all GBR carryings being assigned with resource when having reached MBR speed simultaneously, GBR bearing resource total amount still has remaining situation to occur.By revising GBR bearing resource ratio, the size of restriction GBR bearing resource total amount, there will not be for GBR carries over-allocation resource and cause the phenomenon of NON-GBR bearing resource deficiency, GBR is carried carry with NON-GBR to obtain comparatively sufficient resource, improve the business experience of user.
Another embodiment of the present invention provides a kind of resource allocation methods more optimized, and as shown in Figure 2, the method comprises:
If the 2011 GBR carryings being carried as non-emergent business to be allocated, be then this carrying Resources allocation to be allocated when being no more than GBR bearing resource total amount is no more than system spare available volume of resources simultaneously, perform following 202 afterwards.
Wherein, system spare available volume of resources=system allowable resource amount-(all GBR carryings carry with NON-GBR the stock number sum taken).System allowable resource amount is identical with the associated description content in above-mentioned steps 101, is not repeated.
What deserves to be explained is, now GBR bearing resource total amount be system allowable resource amount and last time revised GBR bearing resource ratio product.
202, GBR bearing resource ratio is revised.
What deserves to be explained is, when revising GBR bearing resource ratio, need first to add up resource allocation result, determine the GBR carrying and the NON-GBR carrying that are assigned with resource.
Above-mentioned 202, revise GBR bearing resource ratio and specifically comprise:
When a × b1 > GBR bearing resource total amount, increase GBR bearing resource ratio, wherein, if the GBR that a is Resources allocation carries stock number shared when reaching GBR speed, b1 > 1;
When a × b1≤GBR bearing resource total amount, and during c < GBR bearing resource total amount, reduce GBR bearing resource ratio, wherein, if the GBR that c is Resources allocation carries stock number shared when reaching MBR speed;
When a × b1≤GBR bearing resource total amount, and c >=GBR bearing resource total amount, and during d × b2 < system allowable resource amount-GBR bearing resource total amount, increase GBR bearing resource ratio, wherein, if the stock number that the NON-GBR carrying that d is Resources allocation consumes when reaching maximum limiting speed, 0 < b2≤1, it should be noted that, here maximum limiting speed is not fixing value, for some NON-GBR carryings, maximum limiting speed can be lower one of APN limiting speed and UE limiting speed medium-rate, the speed sum of the multiple NON-GBR carryings being connected to same APN is made to reach APN-AMBR (Access Point Name-Maximum Bit Rate, access point aggregate maximum bit rate) speed time, these speed being connected to the NON-GBR carrying of same APN are APN limiting speed, the speed sum of multiple NON-GBR carryings of serving same UE is made to reach UE-AMBR (User Equipment-Maximum Bit Rate, user's aggregate maximum bit rate) speed time, these speed of serving the NON-GBR carrying of same UE are UE limiting speed,
When a × b1≤GBR bearing resource total amount, and c >=GBR bearing resource total amount, and during d × b2 >=system allowable resource amount-GBR bearing resource total amount, keep current GBR bearing resource ratio.
Wherein, the UE-AMBR speed that each UE has it exclusive, the speed sum of serving all NON-GBR carryings of same UE can not more than UE-AMBR speed.The APN-AMBR speed that each APN has it exclusive, the speed sum being connected to all NON-GBR carryings of same APN can not more than APN-AMBR speed.
What deserves to be explained is, with above-described embodiment unlike, in the step 202 in the present embodiment, when a × b1≤GBR bearing resource total amount, and during c > GBR bearing resource total amount, again the NON-GBR carrying of Resources allocation is judged the demand of resource.The stock number taken when the NON-GBR carrying of Resources allocation reaches maximum limiting speed may exceed or equal the difference of system allowable resource amount and GBR bearing resource total amount, so make d be multiplied by coefficient b2 that one is less than or equal to 1, d × b2 can reflect the larger demand of NON-GBR carrying to resource of Resources allocation, if d × b2 < system allowable resource amount-GBR bearing resource total amount, illustrate if after GBR bearing resource total amount is all occupied, system spare can distribute to the stock number of NON-GBR carrying beyond its larger demand to resource, so the stock number that system spare can distribute to NON-GBR carrying suitably should be reduced, namely GBR bearing resource ratio can suitably be increased, make Resourse Distribute more reasonable.
Otherwise, when a × b1≤GBR bearing resource total amount, and during c > GBR bearing resource total amount, if d × b2 >=system allowable resource amount-GBR bearing resource total amount, illustrate if GBR bearing resource total amount all occupied after, the stock number that system spare can distribute to NON-GBR carrying can not exceed the larger demand of NON-GBR carrying to resource of all Resources allocation, so do not need to revise GBR bearing resource ratio.
Wherein, b2 can be arranged as required, and it is too small that b2 should not be arranged, otherwise GBR bearing resource ratio will be caused too high, makes NON-GBR carry the enough resources of more difficult acquisition.
Above-mentioned 202, namely before increase GBR bearing resource ratio or reduction GBR bearing resource ratio, also comprise:
If the 2012 NON-GBR carryings being carried as non-emergent business to be allocated, being then this carrying Resources allocation to be allocated when being no more than system spare available volume of resources, performing above-mentioned 202 afterwards.
If 2013 carryings being carried as urgency traffic to be allocated, being then this carrying Resources allocation to be allocated when being no more than system spare available volume of resources, performing above-mentioned 202 afterwards.
If the above-mentioned 2011 GBR carryings being carried as non-emergent business to be allocated are then that the process of this carrying Resources allocation to be allocated comprises when being no more than GBR bearing resource total amount and be no more than system spare available volume of resources:
When the stock number≤system spare available volume of resources making the speed of carrying to be allocated reach GBR speed, and e≤GBR bearing resource total amount, and planned assignment stock number≤system spare available volume of resources, and during f≤GBR bearing resource total amount, after judging to be assumed to be carrying plan of distribution Resources allocation amount to be allocated, whether the speed of this carrying to be allocated is more than MBR speed, if not, it is then this carrying plan of distribution Resources allocation amount to be allocated, if, then the speed of this carrying to be allocated is made to reach the stock number of MBR speed for this carrying to be allocated distributes, wherein, stock number sum shared by the stock number that e reaches GBR speed for the speed making GBR to be allocated and carry and the GBR of Resources allocation carry, f for planned assignment stock number and the GBR of Resources allocation carry shared by stock number sum,
When the stock number≤system spare available volume of resources making the speed of carrying to be allocated reach GBR speed, and e≤GBR bearing resource total amount, and during f > GBR bearing resource total amount, after judging that being assumed to be carrying to be allocated distributes GBR bearing resource surplus, whether the speed of this carrying to be allocated is more than MBR speed, if not, be then that this carrying to be allocated distributes GBR bearing resource surplus, if, then the speed of this carrying to be allocated is made to reach the stock number of MBR speed for this carrying to be allocated distributes, GBR bearing resource surplus for GBR bearing resource total amount and the GBR of Resources allocation carry shared by the difference of stock number,
When the stock number≤system spare available volume of resources making the speed of carrying to be allocated reach GBR speed, and e≤GBR bearing resource total amount, and planned assignment stock number > system spare available volume of resources, and during g≤GBR bearing resource total amount, after judging to be assumed to be this carrying distribution system remaining available resource amount to be allocated, whether the speed of this carrying to be allocated is more than MBR speed, if not, it is then this carrying distribution system remaining available resource amount to be allocated, if, then the speed of this carrying to be allocated is made to reach the stock number of MBR speed for this carrying to be allocated distributes, wherein g for system spare available volume of resources and the GBR of Resources allocation carry shared by stock number sum.
What deserves to be explained is, the planned assignment stock number in this step is stock number that the GBR of current non-emergent business carries the stock number of request dispatching or system and estimates according to Resource Management Algorithm to distribute for this carrying to be allocated.
If the above-mentioned 2012 NON-GBR carryings being carried as non-emergent business to be allocated are then that the process of this carrying Resources allocation to be allocated comprises when being no more than system spare available resources:
When planned assignment stock number≤system spare available volume of resources, after judging to be assumed to be carrying plan of distribution Resources allocation amount to be allocated, whether the speed of this carrying to be allocated exceedes maximum limiting speed, if not, it is then this carrying plan of distribution Resources allocation amount to be allocated, if so, then the speed of this carrying to be allocated is made to reach the stock number of described maximum limiting speed for this carrying to be allocated distributes;
When planned assignment stock number > system spare available volume of resources, after judging to be assumed to be carrying distribution system remaining available resource amount to be allocated, whether the speed of this carrying to be allocated exceedes described maximum limiting speed, if not, it is then this carrying distribution system remaining available resource amount to be allocated, if so, then the speed of this carrying to be allocated is made to reach the stock number of maximum limit speed for this carrying to be allocated distributes.
What deserves to be explained is, the planned assignment stock number in this step is stock number that the NON-GBR of current non-emergent business carries the stock number of request dispatching or system and estimates according to Resource Management Algorithm to distribute for this carrying to be allocated.
For the process of above-mentioned 2011,2012,2013 pairs of Resourse Distribute, it should be noted that, GBR bearing resource ratio can be revised after to a Resourse Distribute resource to be allocated, in the process of subsequent allocations resource, again the carrying of this Resources allocation may be redistributed resource as carrying to be allocated, to make Resourse Distribute more reasonable according to business demand.
Flow process below by way of a kind of resource allocation methods describes the present embodiment in detail, and as shown in Figure 3, this resource allocation methods comprises:
301, judge that whether carrying to be allocated is the carrying of urgency traffic, if so, then perform following 302, if not, then perform following 303.
302, being this carrying Resources allocation to be allocated when being no more than system spare available volume of resources, performing following 306 afterwards, revise GBR bearing resource ratio.
Wherein, system spare available volume of resources is identical with the associated description content in above-mentioned steps 2012, is not repeated.
303, judge whether carrying to be allocated is GBR carrying, if so, then performs following 304; If not, then following 305 are performed.
304, when to be no more than GBR bearing resource total amount is no more than system spare available volume of resources as this carrying Resources allocation to be allocated simultaneously, perform following 306 afterwards, revise GBR bearing resource ratio.
Wherein, GBR bearing resource total amount be now system allowable resource amount and last time revised GBR bearing resource ratio product, when being no more than GBR bearing resource total amount for GBR carries Resources allocation, can avoid, into GBR carrying distributes excess resource, causing the situation of NON-GBR bearing resource deficiency to occur.
305, being this carrying Resources allocation to be allocated when being no more than system spare available resources, performing following 306 afterwards, revise GBR bearing resource ratio.
Wherein, system spare available volume of resources is identical with the associated description content in above-mentioned steps 2012, is not repeated.
It should be noted that, when carrying Resources allocation for NON-GBR to be allocated, not by the restriction of GBR bearing resource ratio, namely current system remaining available resource amount can be used for as NON-GBR bearing resource Resources allocation to be allocated, and the situation that doing so avoids NON-GBR bearing resource deficiency occurs.
306, GBR bearing resource ratio is revised.
What deserves to be explained is, in this step, the resource allocation result in above-mentioned steps 302,304,305 can be got, and be assigned with the GBR carrying of resource according to this resource allocation result statistics and NON-GBR carries the stock number taken, and then according to the data correction GBR bearing resource ratio counted.
As shown in figure 3-1, above-mentioned 302, be the method for the carrying Resources allocation to be allocated of urgency traffic when being no more than system spare available resources, specifically comprise:
3011, judge whether system spare available volume of resources is less than this stock number needed for carrying to be allocated, if so, then performs following 3012; If not, then following 3013 are performed.
3012, ending resource distributes, without the need to revising GBR bearing resource ratio.Namely illustrative system remaining available resource amount cannot meet the demand of business to be allocated to resource, is not therefore its Resources allocation.
3013, for this carrying to be allocated distributes the stock number needed for it, above-mentioned 306 are performed afterwards.
The following specifically describes the process of the GBR carrying Resources allocation for non-emergent business, as shown in figure 3-2, above-mentioned 304, when being no more than the method for carrying Resources allocation to be allocated simultaneously GBR bearing resource total amount is no more than system spare available volume of resources, specifically comprise:
3021, judge whether set up, if so, then perform following 3022, if not, then perform following 3023, ending resource distributes if making GBR to be allocated carry the stock number≤system spare available volume of resources reaching GBR speed.
Wherein, GBR speed is the minimum guarantee speed of GBR carrying, and each GBR has the restriction of its exclusive GBR speed, and making GBR carry the stock number consumed when reaching GBR speed is the minimum essential requirement amount of GBR carrying to resource.
What deserves to be explained is, when the stock number making GBR to be allocated carrying reach GBR speed is greater than system spare available volume of resources, illustrative system remaining available resource amount can not meet the minimum essential requirement amount of this GBR carrying to be allocated to resource, so be not that this GBR to be allocated carries Resources allocation.
3022, judge whether e≤GBR bearing resource total amount is set up, if not, then perform following 3023 ending resources and distribute, if so, then perform following 3024.
Wherein, the e stock number that reaches GBR speed for the speed making GBR to be allocated and carry and the GBR of Resources allocation carry shared by stock number sum.
What deserves to be explained is, if GBR carrying to be allocated distributes meet it to after the minimum essential requirement amount of resource, the stock number of having distributed for GBR carrying can exceed GBR bearing resource total amount, if continue as this carrying to be allocated to distribute stock number needed for it, then GBR carry the stock number taken will inevitably more than GBR bearing resource total amount, so be not this carrying Resources allocation to be allocated, to ensure not for GBR carrying distributes excess resource.
3023, ending resource distributes, without the need to revising GBR bearing resource ratio.
3024, judge whether planned assignment stock number≤system spare available volume of resources is set up, and if so, then performs following 3025, if not, then perform following 3031.
Wherein, planned assignment stock number is stock number that the GBR of current non-emergent business carries the stock number of request dispatching or system and estimates according to Resource Management Algorithm to distribute for this carrying to be allocated.
3025, judge whether f≤GBR bearing resource total amount is set up, and if so, performs following 3026; If not, following 3029 are performed.
Wherein, f for planned assignment stock number and the GBR of Resources allocation carry shared by stock number sum.3026, after judging to be assumed to be carrying plan of distribution Resources allocation amount to be allocated, the speed of this carrying to be allocated, whether more than MBR speed, if so, then performs following 3027; If not, then following 3028 are performed.
Wherein, MBR speed is the maximum guarantee speed of GBR carrying, and each GBR carries the restriction of the MBR speed having it exclusive, and the stock number consumed when GBR carrying reaches MBR speed is a maximum demand of GBR carrying to resource.
What deserves to be explained is, under the prerequisite being no more than system spare available volume of resources and GBR bearing resource total amount, for GBR to be allocated carries the restriction that Resources allocation is also subject to its MBR speed, it can not be made to exceed a maximum demand to resource for GBR to be allocated carries Resources allocation.In subsequent step 3027,3028,3030,3033, be no more than on the basis of GBR carrying to a maximum demand of resource, be that carrying to be allocated distributes different stock numbers under different situations, Resourse Distribute can be made more reasonable.
3027, make the speed of this carrying to be allocated reach the stock number of MBR speed for this carrying to be allocated distributes, perform above-mentioned 306 afterwards.
3028, be this carrying plan of distribution stock number to be allocated, perform above-mentioned 306 afterwards.
3029, after judging that being assumed to be carrying to be allocated distributes GBR bearing resource surplus, the speed of this carrying to be allocated, whether more than MBR speed, if so, then performs above-mentioned 3027; If not, then following 3030 are performed.
