The network slice subnet built is added in network slice subnet pond.
In order to preferably illustrate selection scheme when only existing a network slice subnet when creation network slice, tie below
Fig. 7-Fig. 8 is closed to be illustrated:
As shown in fig. 7, there is only a networks to be sliced subnet " control plane subnet A ", and used by eMBB slice A.
The user capacity that eMBB is sliced A demand is 1,000,000.The label of control plane subnet A are as follows: " support slice type: eMBB；Service class
Type: core network control surface；Physical location: city X ".The user capacity that control plane subnet A is supported is 1,500,000, is sliced A by eMBB
After use, the remaining users capacity (surplus capacity) supported is 500,000
It is not set or do not need setting network due to only existing network slice subnet " control plane subnet A "
It is sliced subnet selection strategy.
Network operator receives new user demand, thinks to need to create new eMBB slice B after analysis, be sliced to network
Management function (NSMF) initiates network and is sliced request to create, and NSMF initiates core to network slice subnet management function (NSSMF)
The request to create of network control surface subnet.NSSMF is handled as follows after receiving request:
1), the demand of eMBB slice B is converted to the label of network slice subnet
The demand of eMBB slice B are as follows: user capacity 1,000,000 needs physical location in core network control surface of city X
Net.
It is " to support slice type: eMBB by the label that demand above is converted to network slice subnet；Type of service: core
Heart network control surface；Physical location: city X ".
2) subnet, is sliced according to the label selection network that network is sliced subnet
Subnet label, which is sliced, according to network " supports slice type: eMBB；Type of service: core network control surface；Physical bit
Set: city X " selects the network slice subnet example " control for meeting this label from current network slice subnet pond
Face net A ".
3) the ability judgement of network slice subnet, is carried out
The user capacity that control plane subnet A is supported is 1,500,000, and after being sliced A use by eMBB, the remaining users supported are held
Amount is 500,000, is unable to satisfy the demand (user capacity 1,000,000) of eMBB slice B.
4) dilatation processing, is carried out to control plane subnet A
Since control plane subnet A is unable to satisfy the demand of eMBB slice B, and control plane subnet A currently not up to hold by maximum
Amount, therefore dilatation operation is carried out to control plane subnet A, by capacity expansion to maximum capacity 2,000,000.
5) can meet the needs of associated all-network slice after, judging dilatation and calculate surplus capacity
After control plane subnet A dilatation, total user capacity is 2,000,000, can meet the needs of eMBB slice A (user simultaneously
Ten thousand) capacity 100 is sliced the demand (user capacity 1,000,000) of B with eMBB.Surplus capacity is " user capacity: 00,000 " (to mean nothing
Method accesses new network slice again).
6) information of control plane subnet A, is sent to network slice management function (NSMF), NSMF carries out network slice wound
The subsequent processing built.
After eMBB slice B is created successfully, the relationship of control plane subnet A and each eMBB slice is referring to Fig. 8.
If S133, choosing multiple label phases with the network slice subnet of the conversion from network slice subnet pond
The network slice subnet matched, then according to automatically selecting of being arranged, policy selection goes out network slice subnet and response to network is cut
Piece subnet distribution request.
Further, the method also includes steps: calculating and update the residue of the network slice subnet chosen
Ability.
Specifically, can determine whether surplus capacity to the network slice sub-network correlation other networks slice example ability whether
There are influences, if there is influence, then the configuration of modification network slice subnet automatically.
In order to preferably illustrate creation network slice when there are multiple networks be sliced subnet when selection scheme, below in conjunction with
Fig. 9-Figure 10 is illustrated:
As shown in figure 9, there are three networks to be sliced subnet: " control plane subnet A ", " control plane subnet B " and " control face
Net C ".
Control plane subnet A, control plane subnet B label having the same, corresponding network slice subnet automatically select strategy
It is set as " optimal selection ".
The label of control plane subnet C and the difference of control plane subnet A, control plane subnet B.
Control plane subnet A is used by eMBB slice A, and the user capacity that eMBB is sliced A demand is 2,500,000.Control plane
The label of subnet A are as follows: " support slice type: eMBB；Type of service: core network control surface；Physical location: city X ".
Control plane subnet B is used by eMBB slice B, and it is 2,000,000 that eMBB, which is sliced the user capacity that B needs,.Control plane
The label of subnet B is identical with the label of control plane subnet A.
Control plane subnet C is not sliced by network also and uses.The label of control plane subnet C are as follows: " support slice type: eMBB；
Type of service: core network control surface；Physical location: city Y ".
Network operator receives new user demand, thinks to need to create new eMBB slice C after analysis, to network Pipe Cutting
It manages function (NSMF) and initiates network slice request to create, NSMF initiates core net to network slice subnet management function (NSSMF)
The request to create of control plane subnet.NSSMF is handled as follows after receiving request:
1), the demand of eMBB slice C is converted to the label of network slice subnet
The demand of eMBB slice C are as follows: user capacity: 800,000, need physical location in core network control surface of city X
Net.
It is " to support slice type: eMBB by the label that demand above is converted to network slice subnet；Type of service: core
Heart network control surface；Physical location: city X ".
2, subnet example is sliced according to the label selection network that network is sliced subnet
Subnet example label, which is sliced, according to network " supports slice type: eMBB；Type of service: core network control surface；Physics
Position: city X " selects the two networks slice subnet example for meeting this label from current network slice subnet Instances Pool
" control plane subnet A " and " control plane subnet B ".
Since there are qualified multiple networks to be sliced subnet example, and the selection strategy in the present embodiment is " optimal
Selection ", therefore choose a network according to optimal selection strategy and be sliced subnet: from qualified two networks slice subnet
Obtain the maximum network of surplus capacity and be sliced subnet: the surplus capacity of control plane subnet A be " user capacity: 500,000 ", control plane
The surplus capacity of subnet B is that " user capacity: 1,000,000 ", therefore control plane subnet B is selected.
3, the ability judgement of network slice subnet is carried out
The user capacity that control plane subnet B is supported is 3,000,000, and after being sliced B use by eMBB, the remaining users supported are held
Amount is 1,000,000, can satisfy the demand (user capacity 800,000) of eMBB slice C.Therefore control plane subnet B is the net of final choice
Network is sliced subnet, and after control plane subnet B is sliced C use by eMBB, remaining ability becomes " user capacity: 200,000 ".
4, the information of control plane subnet B is sent to network slice management function (NSMF), NSMF carries out network slice wound

Since there are qualified multiple networks to be sliced subnet example, processing module 23 is selected from network slice subnet
It selects policy management module 21 and obtains corresponding selection strategy, and the selection strategy in the present embodiment is " optimal selection ", therefore is pressed
A network is chosen according to optimal selection strategy and is sliced subnet: obtaining surplus capacity from qualified two networks slice subnet
Maximum network is sliced subnet: the surplus capacity of control plane subnet A be " user capacity: 500,000 ", the residual energy of control plane subnet B
Power is that " user capacity: 1,000,000 ", therefore control plane subnet B is selected.
3, processing module 23 carries out the ability judgement of network slice subnet
The user capacity that control plane subnet B is supported is 3,000,000, and after being sliced B use by eMBB, the remaining users supported are held
Amount is 1,000,000, can satisfy the demand (user capacity 800,000) of eMBB slice C.Therefore control plane subnet B is the net of final choice
Network is sliced subnet, and after control plane subnet B is sliced C use by eMBB, remaining ability becomes " user capacity: 200,000 ".
4, the information of control plane subnet B is sent to network slice management function (NSMF) by sending module 24, and NSMF is carried out
The subsequent processing of network slice creation.
After eMBB slice C is created successfully, the relationship of control plane subnet B and each eMBB slice is referring to Figure 10.
