Network slice management system and method for realizing network slice life cycle management

Abstract

The invention discloses a network slice management system and method for realizing network slice lifecycle management. The method comprises the steps: receiving a lifecycle management request transmitted by a communication service management system, and transmitting an interface request to a message middleware module according to the lifecycle management request; sending a request parameter of thelife cycle management request to an NSMF database module for storage; monitoring a message queue in the message middleware module; querying authentication information of a network slice subnet management system corresponding to the interface request from an NSMF database module according to the monitored interface request; calling an interface of the network slice subnet management system according to the monitored interface request and the queried authentication information, thereby realizing a life cycle management function for the network slice instance. By means of the method disclosed inthe technical scheme, end-to-end network slice subnet life cycle management is achieved, error frequency is reduced, andrepair efficiency after errors is improved.

Description

technical field [0001] The present invention relates to the technical field of network slicing, in particular to a network slicing management system for realizing life cycle management of network slicing subnets and a network slicing management method for realizing life cycle management of network slicing subnets. Background technique [0002] In order to maximize the utility of 5G networks, a new network slicing feature is added for 5G networks, which supports end-to-end slicing of 5G networks. In order to realize the management of network slices, the management functions of network slices are newly added in 5G networks, including: Communication Service Management Function (CSMF, Communication Service Management Function), Network Slice Management Function (NSMF, Network Slice Management Function) and network slice sub- Network management function (NSSMF, NetworkSlice Subnet Management Function). [0003] The lifecycle management of end-to-end network slice instances is th...

Problems solved by technology

[0008] In the existing technology, the interface of NSMF is generally called through CSMF, and NSMF directly calls the service interface of NSSMF. If there is a network failure or failure to call the interface, the NSMF system will directly report an error, which will affect the life cycle management of the network slice instance. Once a problem occurs, it will Frequent error reporting affects the realization of the network slicing function
