Abstract: A method for operating a telecommunications network, a service agent for the same and a network management system, equipped with the latter, particularly in the form of at least one computer of a network management system, or a user interface module, in which event messages concerning a network element of the telecommunications network are transmitted to the service agent for maintenance and/or monitoring and/or control service, and the event messages which are irrelevant to the service to be provided by the service agent are filtered out. The service agent determines a relationship between a first relevant event message and a second event message in respect of the service to be provided and instructs output means to output a first event message and a second event message according to the relationship.

Abstract: A method for managing a network management system with management elements, which can forward event information by means of forwarding discriminators, with the aid of which the management elements and/or network elements managed by them can be managed. An operator module, which detects for a selection of management elements event information communication connections existing between them, with the aid of data on forwarding discriminators which operate the respective event information communication connections in the management element, and further graphically outputs the management elements of the selection and also the event information communication connections present between them in each case by way of map representing an event information network on a user interface of the network management system, and also a response module for this.

Abstract: The present invention concerns a method for a network management system for the transmission of event information, as well as a discriminator object, a management object, and a managed object for it. According to the method, the managed object sends event information to the management object which determines, on the basis of filter criteria, which of the event information relates to events to be sent to the management object. For this, it is proposed that the management object or a time-controlled control program sends to the discriminator object a first request message for the purpose of querying at least one event status of the managed object, whereupon the discriminator object sends a second request message to the managed object for the purpose of querying its event status.
