Description
Technical field
The present invention relates to communication technique fields more particularly to a kind of network slice creation method, device, equipment and storage to be situated between
Matter.
Background technique
Currently, industry has further started the research of 5G, and network slice (Network Slice) is a weight of 5G
Want component part.
So-called network slice (Network Slice) refers to the collection of one group of network function and resource by layout and configuration
It closes, this set, which is constituted, can provide the complete logical network of particular network ability and network characteristic.Here network characteristic packet
Include ultralow delay, enhancing bandwidth etc..
Network slice is usually across multiple technology domains, including access net (AN), transmission network (TN), with core net (CN).Network
Slice subnet (Network Slice Subnet) is the subset of network slice, the access net (AN) in network slice, transmission network
(TN) or core net (CN) a network slice subnet can, be separately formed.Network slice example please refers to Fig. 1.
According to 3GPP agreement, management entity is sliced by CSMF (Communication Service Management
Function communication service management function), NSMF (Network Slice Management Function network slice management
Function) and NSSMF (Network Slice Subnet Management Function network is sliced subnet management function)
Three parts are constituted.Such as Fig. 2, three parts major function is as follows:
User can be responsible for being converted into cutting by service subscription request in the portal interface ordering communication service of CSMF, CSMF
Piece request to create notifies NSMF.
NSMF is responsible for the management and layout of network slice.NSMF derives network from network slice request to create Parameter analysis of electrochemical
It is sliced subnet request to create, notifies NSSMF.
NSSMF is responsible for the management and layout of network slice subnet.NSSMF is sliced subnet request to create according to network, obtains
Network is sliced corresponding network service (Network Service) resource model of subnet and business configuration, is handed down to network respectively
Virtualization of function composer (Network Functions Virtualization Orchestrator) NFVO and NE management
System (Element Management) EM, complete resource deployment and business it is open-minded.
The life cycle management of network slice, including prepare, it is on active service, operation, retired four-stage.Preparation stage mainly wraps
Include the blueprint design of network slice, the operation such as verifying, and publication.The military service stage refers mainly to the creation of network slice example.Fortune
Battalion's stage mainly includes the activation of network slice example, is deactivated, and is updated, the operation such as monitoring.Retirement phase refers mainly to net
The termination of network slice example.
Existing network is sliced in visioning procedure, is described according to 28.531 agreement of 3GPP, the creation and nothing of transmission subnet slice
The slice creation of line/core sub-network is why serial two processes are because when creation transmission slice subnet, need to obtain it is wireless/
