Behaviour model for a communication network

A method for generating a behaviour model for at least a part of a communications network which method utilizes:

• a semantically rich ontology-based network model comprising an ontology of which instances represent different events/actions that may occur in the network;
• and
• probability information indicating the probabilistic correlation between said events/actions;
• the method being characterized by the step of:
• generating said behaviour model by creating a plurality of instances of a modelling entity which is modelled in a semantic ontology-based modelling language and has at least three properties of which:
• a first property is a reference to a first instance of said network model ontology, which first instance hence represents a first event/action;
• a second property is a reference to a second instance of said network model ontology, which second instance hence represents a second event/action;
• and
• a third property is a numerical value based on said probability information and representing the probability of said second event/action occurring given said first event/action.

A modelling entity for enabling generation of a behaviour model for at least a part of a communications network which part of a communications network is modelled in a semantically rich ontology-based network model comprising an ontology of which instances represent events/actions that can occur in the network, characterized in that said modelling entity is created in a semantic ontology-based modelling language and has at least three properties of which:

• a first property is a reference to a first instance of said network model ontology, which first instance hence represents a first event/action;
• a second property reference to a second instance of said network model ontology, which second instance hence represents a second event/action;
• and
• a third property is a numerical value representing the probability of said second event/action occurring given said first event/action.
