With the development of the fifth generation mobile communication network (5G) technology, 5G network slicing is a focus of industry attention. The 5G network slice is a networking on demand manner, which allows operators to cut out multiple virtual end-to-end networks on a unified infrastructure, and each network is logically isolated from a wireless network, a bearer network, and a core network to adapt to different service requirements. An end-to-end 5G network slice is a combination of subdomain slices of the radio network, the bearer network and the core network.
In the current network slice flow, the NSMF is a network slice management function, receives a network slice deployment request issued from the CSMF, decomposes an SLA requirement of the network slice into an SLA requirement of a network slice subnet, and issues the network slice subnet deployment request to the NSSMF.
The NSSMF is a network slice subnet management function and is divided into a wireless NSSMF, a transmission NSSMF and a core network NSSMF according to the professional field. NSSMF in each field receives the network slice subnet deployment requirement issued by NSMF, converts SLA requirement of the network slice subnet into network element service parameter and issues to network element.
For the core Network field, a connection relationship is established between a core Network NSSMF and a Network function Virtualization collaboration system (NFVO); a connection relationship is established between the NFVO and a Virtual Network Function Manager (VNFM) and between the NFVO and a Virtual Infrastructure Manager (VIM).
The NSSMF converts the resource requirement of the network slice subnet into network service, and issues a deployment request of the network service to the NFVO system. NFVO is a core network function virtualization orchestrator, which is responsible for network orchestration and completes orchestration work of network services, network function virtualization and the like; the core network OMC is a network manager of equipment of each manufacturer and is responsible for managing a Virtual Network Function (VNF); the VIM is cloud platform management and is responsible for management of computing, storage and network resources.
Currently, a perfect core network configuration scheme is lacking between the NSMF and a core network sub-slice management function entity (CN-NSSMF), so that creation of a core network sub-slice needs to be completely realized by an Operation and Maintenance manager on an Operation and Maintenance Center (OMC) of a core network by manually deploying the network, and the network slice cannot be automatically created.
Fig. 1 is a flowchart of a method for creating a core network sub-slice according to an embodiment of the present invention, and is applied to a core network sub-slice management functional entity.
