Introduction
Autonomous network is one of the important topics in 5G network. Complexity of 5G network increases with large
number of devices and diversity of services. Different autonomous mechanisms are introduced by the industry to reduce
the complexity of mobile network and service management. Moving from a manual operating network to a fully
autonomous network requires a stepwise progression. For each step there are different capability and performance level
of autonomy. Thus the concept of autonomous network levels and corresponding requirements are introduced to
describe and evaluate each level in details.

4 Concepts and background
4.1 Autonomous network concept
The network become complex due to large number of devices and diversity of services. Different autonomy
mechanisms are introduced in the industry to reduce the complexity of network management and control. The ultimate
goal for autonomous network is to enable telecommunication system (including management system and network) to be
governed by itself with minimal to no human intervention by utilizing the autonomy mechanisms (including intelligence
mechanism, e.g. AI/ML, and automation mechanism, e.g. rule-based automatic control, and other mechanisms to enable
the autonomous network). Autonomous network can reduce the operating expenditure (OPEX) associated with the
autonomous management and control of the complexity network and improve the service experience to enable various
vertical industries (e.g. autonomous vehicle, smart city). Following are concepts related to autonomous network:
- Autonomous network is telecommunication system (including management system and network) with autonomy
capabilities which is able to be governed by itself with minimal to no human intervention.
- Autonomous network level is used to describe the level of autonomy capabilities in the autonomous network.
- Self-Organization Network, Management data analytics, Intent driven management, closed loop SLS assurance
are examples of enablers for autonomous network.
4.2 Autonomous network level concept
Different autonomy mechanisms in the telecommunication system may lead to different capabilities of autonomy and
different operation efficiency on network management and control workflow, and indicates the level of autonomy of the
network. The term Autonomous network level is used to describe the levels of autonomy capabilities in the autonomous
network to improve the efficiency for network management and control. Participation of the human and
telecommunication system in the network management and control workflow are different for each level and are
important factors to evaluate the autonomous network levels. For each autonomous network level, some tasks can be
performed by telecommunication system, some performed by human, and some performed by cooperation of human
and telecommunication system. For example, in the highest autonomous network level, all tasks are performed by
telecommunication system.
4.3 Dimensions for evaluating autonomous network levels.
4.3.1 Introduction
This clause describes the dimensions i.e. scenarios, management scope and workflow, which can be used for evaluating
autonomous network level.

3GPP TS 28.100 version 17.0.0 Release 17 9 ETSI TS 128 100 V17.0.0 (2022-05)
4.3.2 Scenarios
The autonomous network can be implemented for different scenarios, the complexity of autonomous network depends
on the detailed scenarios where it is applied. Also it will be more challenging for the telecommunication system to
achieve the autonomous network for full scenarios than for certain scenarios. The autonomy capabilities of the scenarios
will impact the autonomous network level for the whole autonomous network.
Following are scenario types categorized by network and service management process for autonomous network:
- Network and service planning
- Network and service deployment
- Network and service maintenance
- Network and service optimization
NOTE: The network and service planning is not addressed in the present document.
4.3.3 Management scope
The autonomy can be implemented in different scopes, the complexity of autonomous network depends on its
applicable scope. For example, it will be more challenging for the telecommunication system to achieve the
autonomous network on cross domain network layer than domain network layer, because more autonomy mechanism
needs to be introduced for the coordination between different domains. The autonomy capabilities of the management
scope will impact the autonomous network level for the whole autonomous network.
Following are applicable scopes for autonomous network:
- Autonomy in NE/NF layer, which means the autonomy mechanisms are executed in the NE/NF.
- Autonomy in domain network layer, which means the autonomy mechanisms are executed in the MnF(s) in
domain.
- Autonomy in cross domain network layer, which means the autonomy mechanisms are executed in the MnF(s) in
cross domain.
- Autonomy in communication service layer, how to execute the autonomy mechanisms are executed in MnF(s)
for communication service.
Note: autonomy in communication service layer is not specified in the present document.

4.3.4 Workflow
Workflow is used to describe the necessary steps to achieve certain management and control purposes. A workflow is
composed of one or more management and control tasks. Each workflow task may be accomplished by human, or

without human intervention. The autonomy capabilities of the tasks in the workflow may impact the autonomous
network level.
Following are the categorization of the tasks in a workflow:
