Autonomous System and Network Automation Framework
Version 1.0 , 29 September 2022 Page 3 (60)
Abstract
This document describes a high-level framework, in terms of entities and functions that
characterise autonomous system capabilities with an E2E (end-to-end) system perspective.
Architectural considerations, associated with autonomous system capabilities, endowed with
Artificial Intelligence/Machine Learning (AI/ML) models of cognition and application are
delineated as high-level requirements. The term "system" is an abstraction, which generalizes
and subsumes details such as specific networks, protocols, and implementations, in terms of
high-level requirements, perspectives, and insights.
The E2E system imbued with autonomous system capabilities consists of a virtualized
environment, with network slicing as a foundational building-block, for the realization of
flexible, granular, and optimized allocation of system resources, such as computing,
networking, and storage, for enabling network automation, without human intervention. The
application of assorted AI/ML models, facilitate autonomous system behaviours to suit
diverse deployment arrangements.
The architectural framework is intended to serve as guidance in the development of inter-
operable and market enabling specifications, for a continuing advancement of the 5G
ecosystem of heterogeneous access, virtualization, forward-looking service enablers, and
emerging usage scenarios.
