Integration of telecommunication networks in monitoring system using domain ontologies

This paper discusses the problems of designing cloud-based telecommunication network monitoring systems based on the construction and application of models of such networks in the form of knowledge graphs. The proposed monitoring systems combine the functions of systems used by various telecommunications network operators. The considered design approach involves the use of a number of common ontologies and domain-level ontologies, such as the telecommunications services domain ontology (TSDO) and the hybrid telecommunications network (ToCo) ontology. To take into account the specifics of networks and operators in the developed monitoring system, an extension of the domain ontology is provided. The article considers the case of combining telecommunication networks built on the basis of different domain-level ontologies or without using an ontological model, by adding new ontologies, within the framework of one monitoring system. To automate the design process, an algorithm for comparing classes of domain ontologies with components of telecommunication network models is proposed. The application of the proposed approach is shown on the example of the problem of adding a new network segment to the monitoring system of a cable television operator.
