A.6 Utilization of management services in functional management architecture

28.5333GPPArchitecture frameworkManagement and orchestrationRelease 17TS

The management services for a mobile network including network slicing may be produced by a set of functional blocks. This annex shows an example of such deployment scenario where functional blocks (such as NSMF, NSSMF, NFMF and CSMF) are producing and consuming various management services.

Figure A.6.1: Example of functional management architecture

In this deployment example:

– NFMF (Network Function Management Function) provides the management services for managing one or more NF(s) and may consume some management services produced by other functional blocks.

– The NF provides some management services, for example the NF performance management services, NF configuration management services and NF fault supervision services.

– NSSMF provides the management services for one or more network slice subnets and may consume some management services produced by other functional blocks.

– NSMF provides the management services for one or more network slices and may consume some management services produced by other functional blocks.

– MDAF provides the Management Data Analytics Service for one or more NF, network slice subnet and/or network slice, and may consume some management services produced by other functional blocks.

– CSMF consumes the management service(s) provided by the other functional blocks. This deployment example does not illustrate what management services the CSMF consumes.

– EGMF provides management service(s) with applied exposure governance and a management service with management capability exposure governance to one or more management service consumers and may consume some management services produced by other functional blocks.

– One functional block may consume the management service(s) provided by another functional block, depending on the management scope of the functional block(s). The scope may be expressed in the terms of Management Service Components (see clause 4.3).
