Before the technical solution explanation to the embodiment of the present invention, first in conjunction with attached drawing to the applied field of the embodiment of the present invention Scape is illustrated.Referring to Fig. 1, a kind of schematic diagram of NFV framework provided by the embodiments of the present application.The NFV framework includes NFV ISG A series of network elements of definition, specifically, network element involved in the NFV framework and its function are as follows:

OSS (Operations Support Systems, Operation Support System) or BSS (Business Support System, business support system) include traditional management function, and for virtualization applications realize with composer (English: Orchestrator it) interacts, to complete the operation and maintenance to network.

NFVO (NFV Orchestrator, NFV composer) major function is the network service realized in provider domain The infrastructure layer of (Network Service, NS) life cycle management (such as deployment/dilatation/capacity reducing/offline) and NFV The function such as (Network Functions Virtualization Infrastructure, NFVI) resource layout, tactical management Energy；Wherein, NFVO decomposites the demand to each VNF, cooperation VNF management according to NS description template (NS Descriptor, NSD) The deployment of (VNF Management, VNFM) realization VNF.

VNFM major function is the life cycle management realized to VNF, such as deployment/dilatation/capacity reducing/offline automation energy Power；VNFM decomposites the demand to virtual resources such as virtual machines according to template and VNF capacity requirement, with Orchestrator, The instantiation of VNF is completed in VIM cooperation.

VIM (Virtualised Infrastructure Manager, Virtual base facility resource manager) main function It can be the management and monitoring realized to entire infrastructure layer resource (such as calculating, storage, Internet resources).

EM (Element Management, NE management) or EMS (Element Management System, network element Management system) major function is to be managed to conventional network elements, such as manage each VNF example etc..

NFVI (infrastructure layer of Network Functions Virtualization Infrastructure, NFV) It may include (Virtual Computing) in NFVI specifically for the infrastructure construction to NFV, Virtualisation Layer and hardware resource (Hardware resources).

The core concept of NFV technology is network function in logic to decouple away among example hardware equipment, with Its network construction cost that basic telecommunication network operator can be greatly reduced and operation cost.NFV example passes through net Meta software may operate in network element on various general hardware；It is and by MANO system, network element deployment process is automatic Change, operator can need quickly dynamically to carry out scalable appearance according to business.

Further include in the License Management of NFV framework PDP (Policy Decision Point, policy decision point), The functions moulds such as PEP (Policy Enforcement Point, Policy Enforcement Point) and License catalog (licensing catalogue) Block, wherein PDP is for generating scheduling strategy, such as determines whether are the VNF example with incidence relation and each VNF example License is applied for and the License can share.PEP is used to execute the scheduling strategy of PDP and obtains License.Institute License catalog is stated for storing the License of all VNF examples, and needed for the VNF example newly to apply issues it License。

According to above-mentioned analysis and introduction to NFV framework, from PDP, PEP and License catalog's of License The NFV framework of reference can be taken out following 4 kinds of models, as shown in Figures 2 to 4 by angle.

A kind of logical abstraction figure of License Management is shown referring to fig. 2, includes NFVO and at least one in the abstract graph VNF example, wherein including the functions such as PDP, PEP and License catalog in the NFVO, for VNF example License is managed and permits.In addition, it is optional, PDP, PEP and catalogue can also be separately positioned on different network elements In.Such as shown in Fig. 3, by PDP and License catalog configuration in OSS, the management function to License is realized, it will PEP is configured in MANO, is distributed corresponding License for implementation strategy and license and is given VNF example.Or as shown in figure 4, By PDP configuration in NFVO, by functional configuration such as PEP, company-information and License catalog in License Manager.This Outside, different structures can also be divided to the network element in NFV framework according to demand, and is not limited to three kinds of sides provided in this embodiment Formula not limits this application.

In order to realize association between different VNF examples and shared in each embodiment of the application, it is thus necessary to determine that a VNF Whether have incidence relation between example and others VNF example, the incidence relation having between VNF example is described below.

The first relationship: active and standby mutual-aid relation

The active and standby mutual-aid relation, or referred to as master-slave redundancy backs up, that is, includes that a main VNF example and one are standby The VNF example of part, and one or more License is shared between the main VNF example and the VNF example of backup, and Synchronization only has the License of main VNF example to come into force.

Second of relationship: load sharing relationship

The load sharing relationship refers in two or more VNF examples that each VNF example has one License, each License can control or authorize multiple control items.Multiple VNF examples share out equally the business of system.Such as All business of the fruit network system are indicated by total capacity, then under normal circumstances, each VNF example or each equipment Processing capacity=total capacity/equipment number.When wherein some VNF example breaks down or migrates, service cannot be provided When, other VNF examples with load sharing relationship share the control item of the VNF example, at this time remaining VNF example Processing capacity=total capacity/(equipment number -1).

In load sharing relationship, it is known as Pool networking there are also a kind of special relationship, the Pool networking relationship can be with It is interpreted as, under normal circumstances, N number of VNF example or equipment form a pond, and equipment is worked in pond with load sharing mode, and one When some VNF example of denier or equipment fault are failed, then its business is taken over by other available devices in pond.

As shown in figure 5, showing a kind of relation schematic diagram in disaster tolerance group VNF example off the net, including above-mentioned independence (English Text: standalone) VNF example, such as VNF1 and VNF4 further includes the VNF2-1 and VNF2- with active and standby mutual-aid relation 2, VNF3-1 and VNF3-2 with load sharing relationship.Wherein, VNF2 and load sharing relationship with active and standby mutual-aid relation VNF3 between also interconnect.By establishing different incidence relations to different VNF examples, play the role of redundancy backup, To guarantee the safety and stability of communication network.

The technical solution of the application will be provided with the VNF of the incidence relation based on the incidence relation between above-mentioned VNF example License corresponding to example forms a resource pool, and realizes that License's is shared.To License policy enforcement procedure In, according to the incidence relation of the VNF example of application, the License whether again operation such as application or release is determined, to reduce The waste of License.Specifically, for above-mentioned Fig. 2 into Fig. 4 difference NFV framework abstract model, to provided by the present application License sending method is described in detail.

Embodiment one

In the present embodiment, be applied to technology scene shown in Fig. 2, the scene include PDP, PEP, License catalog, At least one VNF example, wherein PDP, PEP and License catalog is configured in first network equipment, example In NFVO equipment, the sending method of License is included the following steps:

As shown in fig. 7, step 101: first network equipment obtains the first request message for applying for License, described First request message include the first VNF example identity and the License corresponding at least one control item function.

Wherein, the identity is used for the first VNF example of unique identification, and each VNF example is one corresponding Identity, such as ID.First request message is for applying for that first network equipment distributes License.Optionally, described One request message can directly have the initiation of the first VNF example, other network entities, such as NFVO can also be entrusted to replace first VNF example removes application License, not limits this present embodiment.

Step 102: the incidence relation of the first VNF example is determined according to the identity.Wherein, the association is closed System includes: active and standby mutual-aid relation and load sharing relationship.

In one implementation, first network equipment determines that the association of the first VNF example is closed according to the identity The process of system include: first network equipment according to the identity, network service (Network Service, NS) example and Network service description template (NS Descriptor, NSD) determines the incidence relation of the first VNF example.

Since NSD is the presentation after network design/planning, and the incidence relation between VNF example is the network planning/design As a result, therefore can determine the incidence relation of VNF example by NSD.Specifically, comprising multiple in the NSD information model Ns Deployment Flavour (referred to as: NsDf), each NsDf represents the network topology knot under some network throughput The processing capacity of structure and each VNF/PNF, the link processing ability etc. between network element.

Further, the incidence relation of the first VNF example can be indicated by the following table 1.

Table 1

Wherein, include following information in redundancy relationship group:

Table 2

Can be according in redundant group in PDP or PEP, whether VNF Profile belongs to same producer, and whether NE type Consistent etc. condition determines whether the redundant group of isomery can share License.

Optionally, in another implementation, the information that first network equipment also passes through that the first VNF example reports determines The incidence relation of first VNF example.For example, ES/EMS can obtain other during executing the business configuration to VNF example Redundancy mutual-aid relation between network element, therefore ES/EMS can be by the information reporting of mutual-aid relation to OSS, or passes through on VNFM NFVO is offered, so that first network equipment can obtain the incidence relation information of the first VNF example.

Step 103: needed for determining the first VNF example according to the incidence relation and at least one described control item function License。

Specifically, if the incidence relation is active and standby mutual-aid relation, according to the incidence relation and described at least one License needed for a control item function determines the first VNF example, comprising: determining and the first VNF example has active and standby mutual Help the 2nd VNF example of relationship；Judge whether the 2nd VNF example has applied for License, and the License meets Shared condition, it can it is shared, if it is, obtain the License, if it is not, then need for the first VNF example allocation it is new License.

Optionally, if the incidence relation is load sharing relationship, according to the incidence relation and described at least one License needed for a control item function determines the first VNF example, comprising:

Determine that sharing policy, the sharing policy include for each VNF example application one according to the load sharing relationship A License, or be multiple one shared License of VNF example application, it include described in the shared License All control item functions of multiple VNF examples.

If the sharing policy is for each one License of VNF example application, according to the first VNF example Identity and at least one described control item function lookup matched License, and match described License needed for License is determined as the first VNF example；

Step 104: the License is sent to the first VNF example.

If License needed for the first VNF example can share in step 103, the shared License is obtained, For example, obtaining from shared resource pond, the License is then distributed into the first VNF example.

Wherein, the License includes authorization message, the identification information etc. in License file or License, such as Fruit is License file, then the License is sent to the process of the first VNF example are as follows: first network is set in step 104 It is standby that the License file is sent to the first VNF example.First VNF example is downloaded after receiving the License file, so The License of downloading is loaded and used again afterwards.

Another implementation includes, if the shared License is the authorization message in License, first The process of network equipment transmission License are as follows: the authorization message in the License is first converted into message parameter, then again The message parameter is sent to the first VNF example.In this case, first network equipment only sends conversion Authorization message in License gives the first VNF example, avoids sending or distributing a big License file, only sends message Parameter has saved transfer resource, and transmission speed is fast, the time is short.

Optionally, further include a kind of implementation: the shared License be a License identification information, first The identification information is sent to the first VNF example by the network equipment, after the first VNF example receives the identification information, according to this The content of identification information obtains corresponding License into the first network equipment.

In the present embodiment, first network equipment specifically permit or send License to the mode of the first VNF example include but Above-mentioned three kinds are not limited to, can also include other possible implementations, the present embodiment not limits this.

License sending method provided in this embodiment, the pass of the VNF example is determined by the identity of VNF example Connection relationship, since License can be shared between the VNF example with incidence relation, so the shared License can be permitted , to realize the License association between different VNF examples and share, it can reduce unnecessary to the VNF example of request License waste, improves the utilization rate of License resource.

Optionally, in the step 102 of above-described embodiment: determining that the association of the first VNF example is closed according to the identity Before system, this method further include: judge whether the first VNF example has applied for License and the License is full The shared condition of foot；If having applied for that the License of License and this application can share, execute described according to Identity determines that the step of incidence relation of the first VNF example, (including step 102 was to step 104)；If it is not, then determining one A new License, and the new License is sent to the first VNF example.

Further, first network equipment determines that the process of a new License includes: to obtain the first VNF reality At least one control item information required for example；The new License is determined according at least one described control item information, and The new License supports at least one control item function required for the first VNF example.Specifically, described first The network equipment can obtain the new License from License catalog, and the new License is licensed to institute State the first VNF example.For example, first network equipment obtains needed for the first VNF example from License catalog Then the License is sent to the first VNF example of requesting party by License.

In addition, optional, first network equipment should also after obtaining new License in License catalog New License is stored in shared resource pond, in case license uses when next first VNF example request.

In the present embodiment mode, there is the shared resource pond of the VNF example of incidence relation by establishing, to realize difference License between VNF example is shared, and the VNF example of request is then distributed to further according to determining shared License license, Improve the utilization rate of License resource.

In the present embodiment, the method also includes how using shared when the first VNF example breaks down or migrates The step of License in resource pool, specifically, method further include:

Step 105: first network equipment, which obtains, is used to indicate the instruction letter that the first VNF example breaks down or migrates Breath, the identity indicated in information including the first VNF example.

Step 106: determining whether meet with License corresponding to the first VNF example according to the identity Whether shared condition judges in shared resource pond comprising sharable License needed for the first VNF example.

Step 107: if meeting the shared condition, not discharging License corresponding to the first VNF example； Otherwise, License corresponding to the first VNF example is discharged, while refreshing the incidence relation information in shared resource pond.

Method provided in this embodiment should by judgement when some VNF example is abnormal, such as when failure or migration Whether failure or the VNF example of migration have applied for License, and are released according to court verdict to License in shared resource pond Incidence relation or release, to guarantee the validity of License in shared resource pond.Wherein, when judgement be abnormal Between VNF example exist with incidence relation other VNF examples when, do not discharge the shared License, and be to continue with by License is supplied to the use of other VNF examples with incidence relation, to realize real load sharing, avoids again The new License of application reallocation, causes unnecessary License to waste.

Optionally, method provided in this embodiment further include: dilatation is carried out to shared resource pond.Specifically, the dilatation The step of it is as follows:

First network equipment obtains the second request message, includes the identity of the 3rd VNF example in second request message At least one control item function needed for mark and the 3rd VNF example.

According to the identity of the 3rd VNF example and at least one described control item function, the shared resource pond is judged In whether can be the 3rd VNF example allocation License, that is, judge the control of the License stored in current shared resource pool Item function processed whether include the 3rd VNF example request at least one control item function.

If not including, need to carry out the shared resource pond dilatation, a kind of method of dilatation includes: PEP to PDP The instruction information for being used to indicate shared resource pond dilatation is sent, includes that the 3rd VNF example needs to expand in the instruction information At least one the control item function of holding.PDP receives the instruction information, and as needed the control item of dilatation from License License needed for obtaining the 3rd VNF example in catalog, and the License is sent to PEP, PEP receives the License Afterwards, it is added in shared resource pond, the License needed for sending it to the 3rd VNF example after dilatation；If packet It includes, it is determined that License corresponding at least one control item function of the 3rd VNF example, and the License is sent out Give the 3rd VNF example.

In the present embodiment, by carrying out dilatation to more than the control item stored in shared resource pond, and then increase shared The License of resource pool improves the utilization rate in shared resource pond, and works as in these shared License and occur some When VNF example breaks down, the License corresponding to it can be distributed to other VNF examples with mutual-aid relation, realized License's shares and shares between each example.

Embodiment two

Method provided in this embodiment can be applied to above-mentioned technology scene as shown in Figure 3, the NFV that PEP is separated with PDP Framework, wherein PDP and License catalog can be configured in OSS or NFVO, PEP can be configured in MANO or In person's License Management device, specifically as shown in fig. 7, this method comprises:

Step 201:PDP obtains the first request message of VNF2-1 example request application License, and first request disappears Identity in breath including VNF2-1 example and at least one control item function needed for it.

Optionally, the VNF2-1 example directly can initiate first request message to PDP, can also be by other Network element, such as NFVO replace VNF2-1 example to go to send the first request message of application License.

Wherein, when VNF2-1 is instantiated to PDP application License, it should be noted that in each embodiment of the application, VNF example can according to specific embodiment instantiate it is forward and backward, send the first request message in the process, the application refuses Limitation.In addition, triggering VNF2-1 example initiation License request message can be NFVO or VNFM etc., the application couple This is not limited.

Step 202:PDP receives first request message, judges that it is according to the identity of the VNF2-1 example The no License for having applied for License and the application can share.

Step 203: if it is not, then needing for one new License of VNF2-1 example allocation.

Detailed process includes: the incidence relation that PDP determines VNF2-1 example according to NSD and NS example.Specifically, judgement should VNF2-1 example is active and standby mutual-aid relation or load sharing relationship.If it is determined that being between VNF2-2 example and VNF2-1 example Active and standby mutual-aid relation, but VNF2-2 example does not create currently or cannot share License according to the two regular examples, then It needs for one new License of VNF2-1 example allocation.

Further, the process that new License is distributed in step 203 includes: that PDP is obtained required for VNF2-1 example At least one control item function determines according at least one described control item function and supports these control item function services License, and the License is obtained from License catalog.Wherein, it is stored in advance in the License catalog The License of all control item functions in network.

The message for carrying the new License is sent to PEP by step 204:PDP, includes VNF2- in the message At least one control item function needed for the identity and/or VNF2-1 example of 1 example.

The new License is sent to VNF2-1 example by step 205:PDP.

Wherein, the mode for sending License includes following at least two mode: a kind of mode is: PDP is by License File is sent to the VNF2-1 example, alternatively, another way, the authorization message in the License is converted into disappearing by PDP Parameter is ceased, these message parameters are then sent to VNF2-1 example again.

Above step 202 to step 205 be PDP to the application of VNF2-1 example and distribute new License process (letter Claim: process 1), judge whether VNF2-1 example has applied for License in above-mentioned steps 202, and the License can be with It further include the method and step of following process 2 when shared.

Step 206: if VNF2-1 example has applied for License, and the License can share, then according to NSD The incidence relation of VNF2-1 example is determined with NS example information.

PDP determines VNF2-1 example and VNF2-2 example according to the identity of VNF2-1 example, NSD and NS example information Between be active and standby mutual assistance relationship, and VNF2-1 example and VNF2-2 example share License-2.

Step 207:PDP is sent to the message that VNF2-1 example shares License-2 with VNF2-2 example is carried PEP, and notify PEP, it is active and standby mutual-aid relation between VNF2-1 example and VNF2-2 example.

Step 208:PEP receives the information, and establishes shared resource pond according to License-2, in the shared resource pond License-2 is shared including VNF2-1 example and VNF2-2 example, and is the information such as active and standby mutual-aid relation between the two examples. As shown in figure 8, for the schematic diagram in the shared resource pond established.Information recorded in the shared resource pond includes: 1. Shared License-2；2. sharable example, VNF2-1 example and VNF2-2 example；3. present mode, active and standby mutual-aid relation Etc. information.

The shared License-2 is sent to VNF2-1 example by step 209:PEP so that VNF2-1 example according to The content of License-2 carries out authorization control to control item function.

Optionally, in step 209, PEP also replys a sound to PDP after receiving the License shared information from PDP Answer message.

Step 210: when VNF2-1 example or VNF2-2 example are abnormal, such as termination (English: termination) When, instruction information can be sent to PDP, include the identity of requesting party VNF example in the instruction information.Wherein, the hair Raw exception includes that VNF example breaks down or migrates.It is abnormal in the present embodiment with VNF2-1 example in order to carry out Explanation.

Step 211:PDP receives the instruction information, and judges whether VNF2-1 example has applied for License and institute The License for stating application can share.

Step 212: if so, License-2 corresponding to such as VNF2-1 example can be shared with VNF2-2 example, then The shared License-2 is not discharged, because the License-2 can continue to be used by VNF2-2 example, but needs to refresh The shared record in shared resource pond, such as record VNF2-1 example are abnormal, and no longer share License- with VNF2-2 example 2, release the binding relationship between two examples.

Wherein, release License described in the embodiment of the present application is it is to be understood that be returned to License for the License It is that subsequent allocations are used to other examples in catalog；Alternatively, the License is returned to supplier, so that being released with this VNF example corresponding to the License put does not use.

VNF2-1 example is abnormal and cannot share the message of License-2 or instruction is sent to by step 213:PDP PEP。

Step 214:PEP receives the message or instruction and updates information in shared resource pond.

Wherein, in above-mentioned steps 212, if it is determined that VNF2-1 example does not share License, then VNF2-1 example is discharged This do not share License because will not influence other examples using License after the shared License of release, and save About certain memory space.

Optionally, when VNF2-1 example is abnormal, which can be rebuild, such as The healing stage rebuilds VNF2-1 example later and the process of above-mentioned steps 207 to step 210 (i.e. process 2) can be performed, so as to New License is obtained, while License resource pool refreshes the new License shared information.

A kind of License sending method under active and standby mutual-aid relation is present embodiments provided, by establishing shared resource Pond, so that can continue to make with its another VNF example with active and standby mutual-aid relation when a VNF example is abnormal With the License of the VNF example of the exception, utmostly sharing for License between VNF example is realized, is reduced unnecessary License waste.

Embodiment three

Method provided in this embodiment can be applied in the NFV framework that PEP is separated with PDP, wherein PDP and License Catalog can be configured in the same network element, such as in OSS or NFVO, PEP can be configured in License Management In device, such as MANO.The difference between the present embodiment and the second embodiment lies in that the present embodiment is the VNF reality for load sharing relationship The association of License and shared between example, specifically as shown in figure 9, this method comprises:

Step 301:PDP obtains the first request message, includes the identity mark of VNF3-1 example in first request message Know and at least one control item function needed for VNF3-1 example.

Optionally, PDP can obtain first request message by NFVO application License.

Step 302:PDP receives first request message, according to the identity of the VNF3-1, NSD, NS example etc. Information judges whether it has load sharing relationship.

Step 303: if it is load sharing relationship, then judging whether VNF3-1 example is to apply for License for the first time.

Step 304: if it is applying for the first time, then control needed for PDP sends VNF3-1 example to License catalog The information of function, then PDP License needed for obtaining the VNF3-1 example in License catalog, such as License-3。

Optionally, the identity for the License-3 and VNF3-1 example that PDP will acquire, the message such as incidence relation hair PEP is given, so that PEP can establish the shared resource pond of License-3 according to these information.

The License-3 is sent to VNF3-1 example by step 305:PDP.

Step 306: if VNF3-1 example is not to apply for License for the first time, being determined according to the load sharing relationship Sharing policy determines that VNF3-1 example shares License using which kind of sharing mode.

Specifically, following two sharing mode is provided in the present embodiment.

Mode one: the License of preparatory each VNF example application oneself, PDP control according to needed for each VNF example Item function is one License of each VNF example allocation in License catalog, and these License are stored In shared resource pond.

Mode two: a big License, the License are established for control item function needed for all each VNF examples For controlling all control item functions of the multiple VNF example, and it is shared by multiple VNF examples.

It realizes that License's is shared if it is employing mode one, thens follow the steps 307a: then according to the body of VNF3-1 example Part mark and the matched License of at least one described control item function lookup, and by the License to match License needed for being determined as VNF3-1 example.The License for referring to and being prestored in the shared resource pond that matches, with And the information such as control item function possessed by the License are identical as License needed for the VNF3-1 example, or The License for applying and storing for it in advance in License needed for VNF3-1 example, that is, shared resource pond.

In the present embodiment, PDP combination NSD and NS example information determines between VNF3-1 example and VNF3-2 example it is negative Lotus shares relationship, and License needed for determining VNF3-1 example is the License-3 in shared resource pond, VNF3-2 example Required License is the License-3 ' in shared resource pond, and by VNF3-1 example and VNF3-2 example sharing mode are as follows: The information such as License-3 and License-3 ' are sent to PEP, so that PEP establishes the shared resource pond of License.

It realizes that License's is shared if it is employing mode two, thens follow the steps 307b: being not required to apply for new License, At least one control item function needed for extracting VNF3-1 example from the shared License, and the control that these are extracted Item function processed is generated corresponding to License needed for VNF3-1 example, then the License is licensed to VNF3-1 example and is used.

For example, the License shared described in mode two includes 100 control item functions, VNF3-1 example application It only include 10 control item functions in License, and this 10 control item functions are comprised in 100 shared control item function Among energy, then from 10 control item functions needed for extraction VNF3-1 example in this 100 control item functions, and this 10 are controlled Item function processed generates a License, and the License is sent to VNF3-1 example.

Step 308: establishing the shared resource pond of License-3 and/or License-3 ', as shown in FIG. 10 and 11, VNF3- It is load sharing relationship between 1 example and VNF3-2 example, and shares License-3 or License-3/3 '.

Step 309: License needed for the VNF3-1 example is sent to VNF3-1 example.Specific license method Identical as the mode of previous embodiment one and embodiment two, this embodiment is not repeated.

Optionally, the above method further include: PEP replys the shared response message of License to PDP, so that in subsequent mistake Cheng Zhong, PEP can carry out authorization control based on License sharing policy.

At this point on the authentication control method of mode one and mode two, can slightly have difference: for example, for mode one: Each sub- License in resource pool has the right to use of priority requisition, i.e. the VNF example of first to file License first obtains and makes With license.When there is multiple VNF examples all to apply for License, the total amount of the License of these applications may be more than shared money The License stored in the pond of source, at this point, first network equipment can determine that application is more than shared resource pond according to request message License plussage and its corresponding VNF example, then further according to License plussage to the dilatation of shared resource pond. Such as PDP is according to control item function included in the request message of each VNF example, it is determined whether carries out to shared resource pond Dilatation.

For mode two: can be whole be managed to the License in shared resource pond and dilatation with License. Since all VNF examples all share a License, so, when the License demand of application is more than to share in resource pool When License capacity, increases the capacity of the shared License, i.e., dilatation is continued to the resource pool, it is real to meet multiple VNF The control item demand of example.

Wherein, the mode of dilatation can obtain new License from License catalog, to increase resource pool Capacity；Alternatively, can also obtain new License by other network elements carries out dilatation, the present embodiment not limits this.

Similarly, as multiple VNF example request License with load sharing relationship, above-mentioned steps can be used 306 are handled to the mode of step 309 (process 2).

In addition, the above method further include: step 310: when VNF3-1 example or VNF3-2 example are abnormal, such as sending out When sending failure or migration, then License is discharged to PDP application.Specially VNF3-1 example sends instruction information to PDP, is used for Instruction discharges License to it, wherein includes the identity of VNF3-1 example in the instruction information.

Whether step 311:PDP receives the instruction information, and determine the VNF3-1 example and other examples with load point Load relationship, and determine whether that the License to VNF3-1 example is done and discharge or update.It specifically, can be according to shared money The creation mode in source pond does different decisions:

A kind of decision mode is shared for the License of mode one: PDP decides whether that release should according to strategy or business The License of VNF3-1 example application, while refreshing shared information.Another decision mode is the License for mode two It is shared: not discharge License, the shared information only refreshed.

Shared information after refreshing is sent to PEP by message by step 312:PDP, to inform that PEP VNF3-1 example is sent out Raw abnormal, shared relationship changes.For example, VNF3-2 example and VNF3-1 example are no longer total when VNF3-1 Instance failure With License-3, the binding relationship of VNF3-1 example is released.

Step 313:PEP receives the message and updates the related information in resource pool.

Optionally, when a certain VNF example is abnormal, and carries out treatment reconstruction to it, the step of the present embodiment can be performed Rapid 306 to step 309 (process 2) process, but if employing mode one in step 311, have shared condition and do not release When putting some License, then it can no longer apply new and issue new License, but be directly bound the VNF being abnormal The original License of example simultaneously refreshes resource pool information.

Method provided in this embodiment solves the automatic problem of management of License under load sharing mode, realizes mutual assistance License between example shares to the greatest extent, reduces unnecessary License waste；When the License exception of mutual assistance, License will not be released, and be allocated to other examples with incidence relation and used, and realize real load sharing.

In addition, the shared and mutual-aid relation that PEP gives according to PDP in the present embodiment, establishes License shared resource pond, The License being managed as unit of pond is realized, mutually enjoys resource between the example of mutual assistance.And not according to the mode of resource pool Together, when being more than the total capacity of License in resource pool to business, dilatation is carried out to shared resource pond, to meet multiple VNF examples Authorization control demand, improve the utilization rate in shared resource pond.

It should be noted that License catalog also can be only fitted in above-mentioned the present embodiment two and embodiment three In PEP perhaps in other License Management devices for do not create or in resource pool not stored License VNF example Distribute new License.Specifically catalog is configured in PEP or PDP, can voluntarily be configured according to technical solution, the application This is not limited.

Present invention also provides the sending methods of license a kind of, for building for all VNF examples with incidence relation Shared license is found, and is realized shared.This method can be executed by Policy Enforcement Point PEP, or be set by other networks It is standby.Specifically, as shown in figure 12, this method includes such as figure step:
