Specific implementation mode
Below in conjunction with the accompanying drawings and specific embodiment present invention is further described in detail.
It is shown in Figure 1, virtual resource configuration method is shared in a kind of baseband pool of offer of the embodiment of the present invention, including following
Step：
S1, the resource requirement according to the wireless communication protocol standards, each class standard supported in baseband pool and respective fictional
Machine configuration setting correlated variables.
Correlated variables includes that the virtual resource total amount that user's request task needs is handled under w consensus standards as Rw(RCw,
RMw), wherein RCwTo handle the computing resource total amount that a user resources need, RM under w consensus standardswFor under w consensus standards
Manage the memory source total amount that a user resources need, all total resources R in entire baseband poolall, defined formula is as follows：
Shared resource total amount RS in baseband poolall, defined formula is as follows：
RSall=γ Rall,
It is fixed under each consensus standard under sub-clustering and services single user request income unit price p=[p1,p2,…,pK], it shares
Dynamic resource allocation virtual resource services income unit price p '=[p ' of single user's request1,p′2,…,p′K], wherein pi=δ Ri
To service the income that the user of single consensus standard i asks, p ' under fixed sub-clusteringi=εipiIt is single for shared resource partial service
The income of user's request of consensus standard i, δ are the income weight factor of fixed resource, εiFor shared resource income weight because
Son (its value takes to prolong and be inversely proportional with configuration respective type resource), the income weight of shared resource under all types consensus standard
Because subvector is ε=[ε1,ε2,…,εK], and its value has certain fluctuation ε ± 5%, usual δ ∈ [0.005,0.01], due to solid
Determine resource unit price and shared resource unit price be all proportional to δ, thus the variation of δ values can only influence finally the averagely value of total revenue and
The optimal value of γ is not interfered with.
S2, according to correlated variables, the user under all types of consensus standards asks sum to obey Poisson distribution that parameter is λ
Under constraints, mathematic(al) representation, founding mathematical models are defined.
Mathematic(al) representation includes that average total revenue in entire baseband pool of N number of moment is J, and fixed pattern formula is as follows：
WhereinTo fix sub-clustering service users request number, k under i-th of consensus standard of n momenti,n
It is that fixed resource part can be most to need service users request number, θ=(1- γ) num under i-th of consensus standard of n moment
More service user numbers,For the shared resource portion under n-th of moment, i-th of consensus standard
Divide service users request number,It at most can user under service agreement standard i for shared resource
Number is asked,The stock number used for current n moment shared resource.
Founding mathematical models need to pay attention to following constraints：That is user's request of all consensus standards whithin a period of time
The sum of number obeys the Poisson distribution that parameter is λ：
WhereinKFor the consensus standard sum supported in baseband pool, ki,nService user is needed to ask at n moment consensus standards i
Ask several, P (λ) parameter is the Poisson distribution of λ.It is up to the mathematical model of the shared resource configuration of target, fixed pattern with system benefit
Formula is as follows：
S3, mathematical model is solved, obtains the shared resource configuration scheme under different user portfolio.
Below by way of experiment simulation, the present invention is described in detail.
Simulation parameter is arranged：
Compatible protocol standard sum K=5 in baseband pool, resource can at most service under arbitrary consensus standard in baseband pool
Number of users num=100 takes δ=0.008 to determine the best shared resource capacity of resource in baseband pool in this emulation experiment,
Shared resource income weight factor vector takes ε=[0.8,0.75,0.63,0.56,0.45] under each consensus standard, other correlation ginsengs
Number is as shown in the table：
Table 1 provides and handles the amount of computational resources and interior that single user needs under each consensus standard used in emulation experiment
Deposit stock number；
Table 2, which provides, fixes the resource unit price of sub-clustering resource and the unit price of shared resource in baseband pool.
Single user asks the stock number needed under 1 each consensus standard of table
The income of single user is serviced under 2 each consensus standard of table
Fig. 2 provides the interior average yield variation diagram for servicing all tasks and being obtained of baseband pool in the case of different total loads,
As shown in Figure 2, shared resource allocation ratio optimal under different loads is different, with the increase of load, is configured in baseband pool
Shared resource ratio is changing.
Fig. 3 provides average yield comparison of three kinds of baseband pool resource distribution models in the case where different user asks loading condition
Figure, the respectively complete fixed administrative model of three kinds of baseband pool resource distribution models, full dynamic management model and the present invention establish mixed
Close administrative model.From the figure 3, it may be seen that when loading relatively low, it, need not be to shared money in the case of fixing administrative model entirely enough
Resource is applied in source pond, therefore complete fixed administrative model is not much different with mixed management model average yield, and full dynamic management mould
Type then needs to configure virtual resource for each user's request dynamic, and expense is larger so income is also minimum.When user asks to load
When amount increases to 350 or more, the inadequate active user of resource in complete fixed administrative model under certain consensus standards uses, and mutually
Between cannot share idle resource, the income for causing system total no longer changes, and mixed management model can call altogether
Enjoy resource in resource pool, take full advantage of resource idle under other consensus standards under complete fixed administrative model, thus income compared with
Greatly.And with the increase of user load, its income also increases full dynamic management model, but opening due to full dynamic configuration
Pin is so that income is still below complete fixed administrative model and mixed management model.(it is more than 1050) when user load amount is excessive, entirely
The average yield of dynamic management model and mixed management model is close, and since load capacity is excessive, System Priority is high by priority
Using maximum return is obtained, i.e. mixed management model turns to all resources shared user, and fix full administrative model by
Therefore the influence of initial configuration finally tends towards stability to later stage income is limited.
Fig. 4 provides user's communication request blocking probability under three kinds of baseband pool resource distribution models and please be averaging with total user
Up to the variation comparison diagram of rate λ, as shown in Figure 4, in the smaller such as λ≤200 of load capacity, user's communication is asked all under three kinds of models
It can be serviced, with the increase of λ, complete fixed administrative model user's communication request occurs and is blocked first, because complete fixed
Each consensus standard distribution resource is fixed under administrative model, when user's request is beyond maximum service number under certain consensus standard, part
User's communication can not obtain corresponding resource, and a part of shared resource reserved under mixed management model can be beyond user
Service, therefore occur user's communication obstruction under mixed management model and lag behind complete fixed administrative model.And full dynamic is managed
Model, resource can give all users to share, shared resource total amount to be more than mixed management model, therefore full dynamic management model
Under there is user's obstruction and lag behind complete fixed administrative model and mixed management model.When user load becomes larger, mixed management mould
Type obtains maximum return to service more users, by more resources cut-in shared resource pond, when user load reaches some
When threshold value, all resources are set as shared in mixed management model, end user's congestion situations are consistent with sharing entirely.
Fig. 5 give system under three kinds of baseband pool resource distribution models be averaged running income with threshold values change comparison diagram, by
Fig. 5 is it is found that as system thresholds change in 5%~20% range, when mixed management model reaches in user's communication blocking rate
When threshold value, larger running income can be obtained under more full dynamic management model and complete fixed administrative model.
Those skilled in the art can be carry out various modifications to the embodiment of the present invention and modification, if these modifications and change
For type within the scope of the claims in the present invention and its equivalent technologies, then these modifications and variations are also in protection scope of the present invention
Within.
