Specific embodiment
Following embodiment of the invention describes technical solution with reference to the accompanying drawings.
In a possible model of network slice, the service of a tenant can be sliced by one or more networks (" is cut
Piece " is properly termed as " slice example ") it provides, and a network slice may include such as access network slice subnet and core
Network is sliced the corresponding one or more son slices of one or more subnets of subnet.In addition, network slice subnet can be with
Including one or more network functions (NF).The embodiment of the present invention provides a kind of for managing the network of network slice and son slice
It is sliced management system.
Referring to Fig. 2, the embodiment of the present invention provides a kind of slice management system, which includes business support system
Unite (BSS) 201 and be sliced managing device 202.The BSS 201 is a network entity, and telecommunications service provider is using it to visitor
Family or tenant carry out service operation.The slice managing device 202 is a creation slice example and the entity for managing slice example.
On logical level, which may include managing the slice management of network slice example (NSI) (slice 1,2,3)
Device 2021, and one or more slice subnet managers of main management network slice subnet example (NSSI) (sub- slice 1 and 2)
(2022,2023).It may include management and layout (MANO) 203 in network slice management system, and MANO 203 is mainly
The virtualization resource of the management of network function virtualization and layout entity, main distribution or adjustment NF.
As described above, the service of a tenant may be supported by multiple slices.If tenant wishes all slices and other
The slice of tenant is completely isolated, and slice managing device will create a slice group for the tenant, and the slice group include can be to
Tenant provides all slices of expected service.When such groups multiple for different tenants creation, each group is isolated from each other.Group
Between isolation mean to distribute in slice group network slice resource cannot by other networks in another slice group be sliced make
With." isolation " can be to avoid the negative effect between different groups of multiple networks slice.For example, one or more in one group
Those of tenant sensitivity or the available good protection of privacy information, and will not be obtained by other tenants not in this group
Or it is shared；Or slice resource those of is only used in one group tenant, will not be used by other tenants not in this group, therefore
It can guarantee the service quality to tenant those of in the group well.
For the slice group kept apart, same slice or consolidated network function cannot be shared by different groups, therefore be cut
Piece is kept apart between different groups, but in one group, and different slices may pass through shared one or more networks
Function is not isolated.In addition, one slice group can be by single tenant according to the type of different tenants respective service request and group
It is exclusive, it can also be shared by multiple tenants.For example, in the group I that tenant 1 monopolizes, " shared NF " is by being sliced B with reference to Fig. 3 A
It is provided jointly with slice C；In by the shared group II of tenant 2 and tenant 3, " shared NF " is mentioned jointly by slice E and slice F
For.Therefore, although group I is separated from each other with group II, there is no mutually isolated, in group II slice E by slice B and slice C in group I
It is also not mutually isolated with slice F.
Referring to Fig. 3 B, each slice group has corresponding attribute information, these attribute informations can reflect out the base of the group
Eigen, and attribute information may include: (1) set type (exclusive or shared)；(2) service type or support supported are cut
Sheet type (smart phone or automatic Pilot)；And (3) use the information (tenant ID) of the tenant of the group.
Fig. 4 is the flow chart for schematically illustrating an implementation process of the invention.Specific implementation process is as follows:
401.BSS tangential section managing device sends slice instantiation request.The request can carry comprising " service type ",
The field of " service-level agreement (SLA) information " and " tenant ID ".
The BSS handles the service request from tenant, and then tangential section managing device sends corresponding slice instantiation
Request.The service type that the service type display carried in slice instantiation request needs to provide to tenant.Service type can wrap
Include enhanced mobile broadband (eMBB), big machinery class communication (mMTC), super reliable low latency communication (uRLLC) etc..EMBB clothes
Service type is used for the scene of such as virtual reality and the big bandwidth requirement of augmented reality needs；MMTC service type is used in wearable
Device and smart grid need support extensive access；And uRLLC service type is used for such as automatic Pilot and remote operation
Etc. scenes.As a kind of selection, slice instantiation request can carry " slice type " rather than " service type " is directly to accuse
Tell that slice managing device will provide what kind of slice.The SLA information indicates the specific of the service that the tenant goes for
Rank or quality.Tenant ID indicates the identity of the tenant.
Alternatively, it is also possible to carry " service isolation " mark in the request.If carrying " service isolation " mark
Will and its value are "Yes", then it represents that tenant wishes that being sliced managing device is that tenant creates an exclusive group.If carried
" service is isolated " indicates and its value is "No", then it represents that tenant wishes that being sliced managing device is that tenant creation one can be shared
Group.If not carrying " service isolation " mark, default can determine that tenant wishes to be sliced managing device for tenant wound
Build an exclusive group.If " service isolation " mark is not carried, then it is determined that tenant wishes one sharable group of creation
And it is feasible, this depends on how that the dependency rule to this is arranged.In an embodiment of the present invention, if do not carry service every
From, it is determined that tenant it is expected that being sliced managing device creates an exclusive group.
402.After receiving slice instantiation request, slice of the slice managing device creation comprising one or more slices
Group.The slice group of the creation includes following attribute field information: the slice type of set type, the service type of support or support,
And the information in relation to tenant ID.
As described above, slice instantiation request can carry mark, mark instruction tenant wishes to be sliced managing device wound
The group built is exclusive or sharable.When creating slice group, the corresponding type of " set type " field record (is monopolized or can be total to
It enjoys).
The service type that each slice can be supported in the service type of the support or the slice type record group of support,
It is corresponding with field " service type " that carries in slice instantiation request.Tenant wishes by carrying field " service type "
Certain form of service is obtained, and according to field " service type ", a slice group will be created by being sliced managing device, including phase
The slice (or slice example) answered, one of them or some slices can individually support certain form of service.For example, a or more
A slice can support smart phone service, and other slices can support automatic Pilot service.If taken in the request
The field of band is " slice type ", rather than " service type ", then slice managing device can be created comprising such slice class
The slice group of type.
Information about tenant ID has recorded the information that slice group is how many tenant and which tenant's service.
Each slice in slice group includes one or more network functions, these functions provide various clothes jointly for tenant
Business.Optionally, each slice in slice group may include multiple sub- slices, and every height slice includes one or more nets
Network function.Compared with each slice, every height slice provides more specific function.For example, access network slice can provide
Corresponding function relevant to access net, and core net string bag slice can provide corresponding function relevant to core net.
In order to create such slice group, slice managing device, which can mark, will belong to the related slices of slice group.For example,
An identical group of ID can be distributed for each slice by being sliced managing device, and then these slices with identical group of ID will be formed
One slice group；To be sliced managing device can be each slice another identical group of ID of distribution, and then these are with identical group of ID
Slice will form another slice group.As long as these slices can be identified as a slice group, described group of ID can be replaced with
Other similar symbol, such as " mark ", " timestamp ".When creating slice group, slice managing device can choose existing slice, or
The new slice of creation, or the existing slice of selection and the new slice of creation, mark them then to create slice group.
Specifically, when being sliced managing device needs creation slice to create slice group, slice managing device can be held
Row following steps:
Step 1.Request is decomposed into different sons by the slice manager in slice managing device requests.
Step 2.Then, this little request is sent respectively to cut accordingly in slice managing device by the slice manager
Piece subnet manager.
Step 3.Then, each slice subnet manager will create son slice according to sub- request.
For example, one request can be sent to access slice subnet manager, the request can carry about slice type,
Subnet request, tenant ID, slice instantiation ID and the information for organizing ID.Then, the access slice subnet manager will be according to institute
It states request and creates sub- slice type and corresponding network function on the sub- slice.Similarly, another request can also be sent
It is sliced subnet manager to core, which can carry identical slice type, different subnet requests, identical tenant
ID, identical slice instantiate ID and identical group of ID.Then, core slice subnet manager will be created according to the request
Corresponding son slice and the corresponding network function on the sub- slice.Finally, this little slice may be constructed required slice.When
Slice managing device only selects existing slice not need step 1-3 when creating slice group.
403.Optionally, the slice managing device can be received further and same tenant's phase described in step 401
Associated another update request.
After in one slice group of creation and for tenant providing certain some period of time in service, which may want to addition and currently cuts
The new demand servicing provided or shearing existing service are not provided in piece group.In this case, the request carries identical tenant ID, and
Service type and SLA information, and the request is also possible to further carry slice group ID.If it is new that the update is adding one
Slice, then carry a new service type and new SLA information；If an existing slice is being modified in the update, take
With identical service type, but SLA information is different.
404.The slice managing device determines that the request for updating, then updates slice group according to the request.
According to slice group ID, it is sliced managing device and determines that it is to update request, then execute and update operation.Even if in request
Slice group ID is not carried, slice managing device can search whether the slice group for having for the tenant by searching for tenant ID
To determine whether the request is to update request.The update operation includes but is not limited to add new slice；Terminate existing slice；In
NF is added in existing slice；Terminate the NF in existing slice；Or reconfigure NF in existing slice；Or their any group
It closes.When by adding new slice or terminating or adjust existing slice to update group, slice managing device can be with tangential section subnet
Manager sends son request, to create son slice according to sub- request or terminate or adjust existing slice.
The update request may also be marked with a mark, show that this is update request when sending the request by BSS.
The BSS can determine whether the request from tenant is used to update, and then marked or do not marked.
405.Optionally, slice managing device can receive requests with the associated slice instantiation of another tenant.The request
Carry the field comprising " service type ", " service-level agreement (SLA) information " and " tenant ID " etc..
406.Slice managing device determines whether the slice group created in step 402 can be shared by other tenants；If
It is then to share slice group with other tenants；If it is not, then creating new slice group for other tenants.
Specifically, slice managing device, which is determined, is instantiating in request whether carry mark with the associated slice of other tenants
Will " service isolation ".If carry " service isolation " mark and its value be "No", and the slice group created in step 402 be can
It is shared, then be sliced managing device and determine that the slice group can be shared by other tenants, and by the slice group created in step 402 with
Other tenants are shared；Otherwise, slice managing device will determine that the slice group cannot be shared by other tenants, be then other tenants
Create another new slice group.If carrying " service isolation " mark, and its value is "Yes" or does not carry " service isolation " mark,
A new slice group will be created for other tenants by being then sliced managing device, and the new slice group will be labeled as " isolation "；Such as
Fruit carries " service isolation " mark, and its value is "No", but the slice group created in step 402 is " exclusive ", then being sliced
Managing device will determine that the slice group cannot be shared by other tenants, then create a new slice group for other tenants, described
New slice group will be marked as " can share ".
In a step 406, slice managing device can not may determine whether the slice group that creates in step 402 can be with completely
It is shared by other tenants, and is always that other tenants create a new individual slice group.Advantage can be creation slice
The process of group is simpler, but due to that must create more slice groups, can waste more Internet resources.
Optionally, as described in step 405, slice managing device can further receive associated with other tenants
Slice updates request, and then the slice managing device updates the slice group according to the request.The specific steps and step 404 of update
Described in it is identical.
Optionally, when slice managing device continues to receive new instantiation request from third tenant, program and step 405
It is similar with described in 406.The main distinction is that slice managing device will determine in step 402 and 406 appointing for tenant's creation
What slice group whether can be shared by third tenant；If there is a slice group can be shared, then being sliced managing device will
The slice group is shared with third tenant；If it is not, slice managing device will create a new slice group for third tenant.
As described above, slice managing device possibly can not determine whether existing slice group can be shared, and directly created for third tenant
Individually new slice group.
In step 405 and 406 the embodiment described, if slice managing device determines that slice group can be total to by other tenants
It enjoys, is then sliced managing device and shares slice group and other tenants.Specifically, slice managing device can be to different slices
Subnet manager sends different requests, with creation son slice.When one in slice subnet manager is creating sub- slice
And when finding to have a network function that can be shared in existing slice, which will further determine whether to answer
Modify sharable network function.Modification includes basic resource change, such as resource expansion.If necessary to change network function
Can, then resource change request can be sent to MANO, while sending configuration change request to NF.After the completion of resource expansion process, institute
It states slice subnet manager to be configured to be shared by different slices by network function, as shown in Figure 3A, slice E and slice F are common
It provides " shared NF ".Similarly, when creating the slice group that tenant monopolizes, slice managing device can be to different slice subnets
Manager sends different the requiring of creation son slice.When there is a network function that can be shared, slice subnet manager will
Network function is shared between different slices, as shown in Fig. 2, " shared NF " is provided jointly by slice B and slice C.
Update about slice group operates, and Fig. 5 gives a specific example.Detailed process is as follows:
501.BSS tangential section managing device sends the request for terminating or adjusting network slice, and the request carries network
Slice instantiation ID and the instruction for terminating or adjusting slice.
502.Slice manager in slice managing device receives the termination or adjusts the request of network slice, and this is asked
It asks and is sent to slice subnet manager, wherein the request carries the son of network slice instantiation ID and termination or adjustment network slice
The instruction of slice.
503.Slice subnet manager terminates or adjusts the slice example.
When terminating slice or son slice example, slice subnet manager determines slice example whether is only existed in group；Such as
Fruit is that slice subnet manager will terminate information relevant to group and information relevant with slice example.Otherwise, it is sliced subnet
Manager only terminates information relevant to slice example.
The adjustment of slice may include the shared NF terminated in dedicated NF or change slice.For NF to be terminated, slice
Subnet manager sends message to MANO, and NF is deleted in instruction.For NF to be changed, it is sliced subnet manager and is sent to MANO
Indicate the message of NF change, and the slice subnet manager further can reconfigure message to NF transmission.
504-505.After terminating subnet slice example, slice subnet manager tangential section manager returns to ACK message, and
The slice manager returns to ACK message to BSS.
Fig. 6 provides a kind of schematic block diagram of possible physics realization of the slice managing device of Fig. 2.It mainly includes receiving
Send out device, one or more processors and memory.The memory stores one or more programs to be made to cut when executed, the programs
Piece managing device executes above-mentioned steps 401-406, and other steps executed by slice managing device.The program is mainly wrapped
It includes:
For receiving the instruction of slice instantiation request associated with tenant by transceiver；
For being the instruction of tenant's creation slice group based on slice instantiation request；
Wherein the slice group includes at least one network slice, and each of at least one network slice includes
One or more NF.
In addition, the program includes the instruction for receiving update request associated with the first tenant by transceiver, with
And the instruction for requesting the first slice group of update according to the update；Wherein, the ID for updating request and carrying the first slice group.
In addition, the program includes updating the instruction of the first slice group, it is used for including to give an order: in the first slice group
Middle addition includes the new slice of NF；Terminate the existing slice in the first slice group comprising NF；NF is added in existing slice；It terminates
NF in existing slice；Or reconfigure NF in existing slice；Or any combination of them.
When the first slice instantiation request carries a field, which indicates that the first slice group is exclusive or can share
, and described program further includes to give an order and be used for: it is real to receive the second slice associated with the second tenant by transceiver
Exampleization request；Determine whether the first slice group can be shared by the second tenant；If it is, with shared first slice of the second tenant
Group；If it is not, then creating the second slice group for second tenant.
In addition, the program includes that following instruction is used for: by with the one or more existing slices of identical group of ID label, or
The one or more slices of creation, then mark the slice of the creation with identical group of ID；Or the one or more slices of creation, so
Afterwards with the same group of one or more existing slices of ID label and the slice of the creation, cut to create first and/or second
Piece group.
As described above, Fig. 2 provides the schematic block diagram of the system for managing the slice of the network in communication network, the network
Slice provides multiple network function NF, uses for one or more tenants.The system includes operational support system (BSS), slice
Managing device etc..Mainly,
