Defining Intent-Based Service Management Automation for 6G Multi-Stakeholders Scenarios

This article aims to explore the requirements and challenges that Intent-Based Management (IBM) systems should look towards to deliver proper automation management in multi-stakeholder 6G scenarios. To do so, the evolution of the telecommunications actors is presented to identify how they will interact with the use of intents and what IBM systems must face to fulfil with the tenants expectations while interacting among other IBM domains (aggregation vs. federation models). In a second step, this article presents how the IBM systems functionalities should be organized (based on standards research and comparative) and a set of enablers using them to properly deliver the automation needed to accomplish the requests done by the tenants. On a third step, a set of End-to-End (E2E) intent-based services are described to illustrate how the different enablers (and the functionalities they use) may work to reach the E2E service goal. Finally, a set of experimental results related to how intent conflicts should be manage is presented, followed by the conclusions.
