From US 6,105,061 a hierarchically distributed network operators is operations management system known which comprises a central network management station and several decentralized network management stations. In the central network management station attributes of network objects are stored, which are monitored by the central network management station. A controller of the central network management station is provided for processing requests for access to network object attributes through the decentralized network management stations. The controller of the central network management station receives the access requests and sends the requested network object attributes to the respective decentralized network management station. Provided that the requested power object attributes are not stored in the central network management station manages the Steueru GS ​​of the central network management station device, the access request associated to selected distributed network management stations for working on.

By the method described in US 6,105,061 hierarchically distributed network management system is essentially perceived only by a configuration management Netzbetriebsfüh- be approximately responsibilities between the central network management station and the remote network management stations divided. Other network management areas, such as fault, performance, and security management, are not considered. but gave an efficient division of Netzberiebsführungsauf- requires incorporating essentially all network management areas, not least with regard to one for network operators and owners economical operation tasking. Profitability problems may particularly arise in operation tasking when operation-tasking services for the operation of communication networks in countries and regions are covered with lower wage levels in countries or regions with higher wages.

The present invention therefore has for its object to provide a method for operating a communications network that enables an efficient division of Netzberiebsführungsaufgaben to provide a method suitable for performing the network management system and a suitable implementation of the method.

In a device or a change of a service, a message with an order to Uberwa- monitoring the availability of network elements is transmitted from the access rights management system 101 to the fault monitoring system 104 that are specified for the provision of the corresponding service to be relevant. In a corresponding manner, a message 125 is transmitted with an application to monitor the quality of service to the Leistungsuberwachungssystem 105th By this Uberwachungsaufträge the fault monitoring system 104 and the Leistungsuberwachungssystem 105 are caused to subnets 106,107,108 detected error messages 127 and measurement values ​​128 that are routed via a subnet and übertragungstechnolo- giespezifisches network operating system 109,110,111 to the fault monitoring system 104 or the Leistungsuberwachungssystem 105, with to compare the information stored in the database Netzelemente- 103 impermissible deviations. For this purpose, corresponding network element database information by the error monitoring system 104 or the Leistungsuberwachungssystem 105 are retrieved and as messages 126 to that transmitted. When an impermissible deviation of the data stored in the network element database 103 information on the fault monitoring system 104 or Leistungsuberwachungssystem 105 generates a message 129,130 ​​by a reduction in service capacity stating the affected service.

The monitoring of the availability and quality of service is carried out in accordance with an agreement made between a customer and a service provider service level agreement. Therefore, to be saved to the information specified by a service level agreement for the provision of a service to be relevant network elements in the network element database 103rd Also, error messages and measured values ​​are acquired only at the specified by the service level agreement for the provision of the service to be relevant network elements. For monitoring specified in a service level agreement requirements, a message 123 with an application for monitoring a quality of service agreement of access rights management system 101 to the fault monitoring system 104 is bermittelt Ü at a device or change a service. This means the detection of error messages or measured values ​​to by the service level agreement for the provision of a service is made as specified relevant network elements already by the establishment or modification of the corresponding service.
