Diversified services have different requirements on the aspects of bandwidth, time delay, safety, reliability and the like of the network. The third Generation Partnership Project (3 GPP) introduced Network Slices (NS), which can be understood as a combination of Network functions and resources required to complete a service(s), as a complete logical Network, with different Network slices being logically or physically isolated. Different service scene requirements are met by creating different Network Slice Instances (NSI), which are end-to-end logical networks and include different Subnet Slice instances (NSSI) and Network Functions (NF).
After the NSI is created, Life Cycle Management (LCM) and operation and maintenance Management including Fault Management (FM), Performance Management (PM), Configuration Management (CM), and the like need to be performed on the NSI. Fig. 1 is a schematic diagram of a conventional network slice management architecture, and as shown in fig. 1, the conventional network slice management architecture adopts a hierarchical architecture, and the management architecture includes: a Communication Service Management Function (CSMF), a Network Slice Management Function (NSMF), a Network Slice Subnet Management Function (NSSMF), a Network Function Management Function (NFMF), a Network Management System (NMS), and a plurality of NFs, which include NF-a, NF-B, and NF-C. Based on the existing management architecture, when a service of the management plane is performed, for example, a CSMF needs to instantiate a new NSI, or a client or a third party needs to acquire management data of an NF, the corresponding management function can be searched layer by layer through an interface between the management functions, and a service flow of the management plane is executed.

The existing management method mixes LCM management and operation and maintenance management of NSI, and is not beneficial to management.
