Abstract: A software object model for modeling (resource instances and resource types in a network management system. The model comprises object instances and object classes. Each class comprises fragments of data and/or program code and is a generalization of one or more object instances. The model models each resource type by an object class and assigns to the class a class version identifier which indicates at least some capabilities of the resource instance/types and a collection of the fragments included in the class of the version in question. The model further models each resource instance by an object instance of the corresponding class, and assigns to the instance an object instance identifier and an instance version identifier which indicate the version of the class used for modeling the resource type in question.

Abstract: A software object model for modelling resources (resource instances (RI) and resource types (RT)) in a network management system. The model comprises object instances (OI) and object classes (OC). Each class comprises fragments (FG) of data and/or program code and is a generalization of one or more object instances (OI). The model models each resource type (RT) by an object class (OC) and assigns to the class a class version identifier (CVI) which indicates at least some capabilities of the resource (RI, RT) and a collection of the fragments (FG) included in the class (OC) of the version in question. The model further models each resource instance (RI) by an object instance (OI) of the corresponding class, and assigns to the instance (OI) an object instance identifier (OII) and an instance version identifier (IVI) which indicate the version of the class (OC) used for modelling the resource type (RT) in question.

Abstract: A method for connecting a network element to a telecommunication system comprising at least one network element, one network management system and one telecommunication network for transmitting data between the network element and the network management system. The method comprises creating, in the network management system, a registration service for registering, in the network management system, services comprised in the network elements; storing, in connection with the network element, an identifier of the registration service by means of which a data transmission connection is established from the network element to the registration service. From the network element, a registration message is transmitted to the registration service whereby the network element services are registered in the network management system wherefrom a registration message is transmitted to the network element. The network management services of the network management system are registered in the network element.
