This annex shows an example of deployment scenario for management of a mobile network including network slicing.

Figure A.8.1: An example of deployment scenario for management of a mobile network including network slicing

In this deployment scenario:

– Network and Network Slice Management Function provides the management services for network or network slice which includes RAN part, CN part and TN part to the Consumer. Network and NetworkSlice Management Function consumes management services for RAN SubNetwork or network slice subnet produced by RAN Management Function, management services for CN SubNetwork or NSSI produced by CN Management Function and interface produced by TN Manager.

– RAN Management Function provides the management services for a RAN SubNetwork or network slice subnet and/or management services for RAN NF(s). RAN Management Function may consume management service for RAN SubNetwork or network slice subnet and management services for RAN NF. In this scenario, the following RAN Management Function(s) are described:

– RAN Management Function A provides the management services for RAN SubNetwork or network slice subnet to Network and Network Slice Management Function. RAN Management Function A consumes the management services for RAN network slice subnet(s) and management services for RAN NF produced by RAN Management Function B, and management services for RAN NF produced by RAN Management Function C.

– RAN Management Function B provides the management services for RAN network slice subnet and management services for RAN NF to RAN Management Function A.

– RAN Management Function C provides the management services for RAN NF to RAN Management Function A.

– CN Management Function provides the management services for a CN network slice subnet and/or management services for CN NF. CN Management Function may consume management service for CN network slice subnet and management services for CN NF. In this scenario, the following CN Management Function(s) are described:

– CN Management Function A provides the management services for CN network slice subnet to Network and Network Slice Management Function. CN A consumes the management services for CN network slice subnet and management services for CN NF produced by CN Management Function B and management services for CN NFs produced by CN Management Function C.

– CN Management Function B provides the management services for CN network slice subnet and management services for CN NF to RAN Management Function A.

– CN Management Function C provides the management services for CN NF to CN Management Function A.
