CONTROL IN AUTONOMOUS TELECOMMUNICATION SYSTEMS USING INTENT ONTOLOGY

Abstract

The article is devoted to the description of management capabilities in autonomous telecommunication systems using ontologies of intents. In modern telecommunication networks, there are trends towards decentralization of systems and endowing their components with the ability to operate autonomously, while the business logic of their operation is determined at the system level, which in many cases requires interaction between several or many system components acting as service providers or consumers. The article considers autonomous networks managed using the TMN model (from the English Telecommunication Management Network - telecommunication management network), which is a multi-level model that includes levels of business management, services, telecommunication network and its components. To manage networks in the paradigm of service providers and consumers, the international association uniting service providers and their consumers in the field of telecommunications TMForum has developed a concept based on the use of ontologies of intents (Intent in Autonomous Networks), which allow formulating management tasks in autonomous networks by defining criteria for managing networks and their elements from the point of view of the intentions of the participants in the interaction to receive and provide services. Due to the fact that the ontology of intentions is described in the OWL format, which represents it as a semantic network of interconnected classes, the article proposes to use a telecommunication network model in the form of a knowledge graph for managing telecommunication networks, which is associated with both the domain ontology of telecommunication networks and the ontology of intentions, which ensures the autonomy of network components due to management using intentions, and the use of a domain ontology in the field of telecommunication networks facilitates integration with third-party suppliers and consumers of the operator's services. The proposed approach to jointly using the ontology of intentions, policies and a network model in the form of a knowledge graph for managing telecommunication networks at the business level is new and its applicability is shown in the article using the example of implementing the registration process and fulfilling an application for connecting a telecommunication service. The considered example shows the possibility of jointly using a telecommunication network model in the form of a knowledge graph built on the basis of a domain ontology and an ontology of intentions when performing high-level business processes for managing an autonomous telecommunication network.
