Unleashing 5G & 6G with
AI-empowered Automation


The ZSM group is currently progressing with its report on intent (ETSI ZSM 011). Intents express declaratively all the operational expectations an autonomous management domain...
service-management domain level and can span multiple management domains. Multiple closed loops can run simultaneously.
ETSI ZSM 009-1 provides capabilities to support coordination, delegation and escalation between closed loops while ensuring intelligent, consistent, and coherent service delivery.

Coordination between loops is essential when there is dependency between their operations or when they can adversely interfere with each other. It can also help to improve their operations and fulfill their goals, for example by sharing information produced by the different closed-loop stages.

This specification also enables the delegation and escalation of respective goals between superior and subordinate closed loops. A superior closed loop can delegate respective goals to the subordinate closed loop(s), for example by setting the policies and/or the intents that allow the subordinate closed loop to act autonomously. A subordinate closed loop can escalate goals to the superior closed loop in a situation, for example, where it is not able to achieve the goal assigned to it. Escalation and delegation support the separation of management and automation into different autonomous areas of concern (end-to-end cross-domain service operations, management domains), where each is responsible for assurance and intelligent automation within its scope.

The ZSM group is currently progressing with its report on intent ( ETSI ZSM 011). Intents express declaratively all the operational expectations an autonomous management domain needs to fulfill and assure, including requirements, goals, and constraints. The report will propose additional management capabilities and services to support intents and their lifecycle management, and recommend whether existing intent models and semantics can be leveraged. It will also suggest how conflicting intents can be handled. The results from the study will provide the basis for a new normative specification.

The group is also working on the specification of additional management capabilities to enable full AI operations within the ZSM framework (ETSI ZSM 012), ensuring support for deployment diversity.  Figure 4 introduces key AI enablers.

These enablers include capabilities to:

  • Access the right data, at the right place and at the right time, while ensuring data integrity and trustworthiness.
  • Support coordination between multiple, distributed AI applications, ensuring a consistent and holistic operational view and the means to act on it. AI applications can collaborate in learning different tasks or contribute collectively to solve a common problem.
