8.3.3 OSS-NF functional components

NOTE – The following description is based on an adaptation of the OSS functional components as described in clause
9.2.5.3 of [ITU-T Y.3502].
The OSS-NF functional components encompass the set of operational related management capabilities that
are required in order to manage and control the network functions offered to customers as part of network
services. Refer to clause 7.8.2.2 for a description of OSS-NF functionalities.
Figure 8-5 shows the OSS-NF functional components.

Figure 8-5 – OSS-NF functional components

The OSS-NF functional components include:
– NF catalogue;
– NF provisioning;
– NF monitoring and reporting;
– NF policy management;
– NF automation;

– NF level management;
– NF incident and problem management;
– NF inventory.

8.3.3.1 NF catalogue
The NF catalogue functional component provides a listing of all network functions of the NaaS CSP. The NF
catalogue functional component contains and/or references all relevant technical information required to
deploy, provision and run a network function.
8.3.3.2 NF provisioning
The NF provisioning functional component provides the capabilities for provisioning network functions, both
in terms of the provisioning of network functions implementations and of network functions access
endpoints and the workflow required to ensure that necessary NF elements are provisioned in the correct
sequence.
8.3.3.3 NF monitoring and reporting

The NF monitoring and reporting functional component provides capabilities for:
– Monitoring the activities of other functional components throughout the NaaS CSP's system. This
also includes functional components involved in the support of network functions, such as other
OSS-NF functional components like the NF automation functional component (e.g., the provisioning
of a network functions instance for a particular customer);
