9 NaaS service operational policy framework

This clause aims to present the NaaS service operational policy framework which consists of elements and
functions provided by the CSP and the corresponding procedure.

9.1 Elements of NaaS service operational policy
NaaS service operational policy data models are operated from creation to execution in the NaaS service
operational policy framework. The main elements of the NaaS service operational policy framework are
described as follows.

9.1.1 NaaS service operational policy administration point

The NaaS service operational policy administration point (NPAP) is responsible for the creation, translation,
and validation of new NaaS service operational policy data models, and the modification of existing ones,
both during design time and runtime execution time. NaaS service operational policy data models are created
with the integration of NaaS service data models.
9.1.2 NaaS service operational policy decision point

The NaaS service operational policy decision point (NPDP) is responsible for the distribution and decisions of
NaaS service operational policy data models. Once the NaaS service operational policy data model is initially
created or an existing one is modified, the NPDP sends it from the repository to the NaaS service operational
policy enforcement point (NPEP) before it is actually needed. In this distributed manner, NaaS service
operational policy data models will be available when needed in order to minimize the latency for real-time
requests or triggers to the NPDP. In some required cases, NaaS service operational policy data models can be
subscribed and automatically updated on the NPEP.
9.1.3 NaaS service operational policy information point

The NaaS service operational policy information point (NPIP) is responsible for storing new NaaS service
operational policy data models in the repository which are verified by the NPAP. The existing ones can be
retrieved in the repository.

In the repository, NaaS service operational policy data models are grouped by different dimensions, which
include, but are not limited to, the corresponding NaaS service data model, the type or category, the lifecycle,
the ownership or administrative domain, the geographic area or location, the technology type, the describing
language and version, and the security level.
9.1.4 NaaS service operational policy enforcement point

The NPEP is responsible for the enforcement of NaaS service operational policy data models during the
runtime execution time.

9.2 Functions of NaaS service operational policy
Table 9-1 provides descriptions of the main functions related to the NaaS service operational policy data
model.
