Abstract

A data storage device includes a CMIP application component which receives data on network objects using the CMIP protocol from the network manager of a main network. For each attribute of each object, a CMIP/SNMP mapper component converts the CMIP object class name, attribute name and distinguished name of the object into the corresponding SNMP attribute value and this data is stored in an MIB. An SNMP application component receives requests for information from a network manager of a local network. In order to service a valid request, the SNMP application component retrieves the required data from MIB and supplies this data to the network manager for the local network using the SNMP protocol. For changes in the values of certain attributes of certain objects, the SNMP application component issues traps to the manager of the local network.

Claims13

Dependent claims

A network management system comprising a first network manager for a first telecommunications network, a second network manager for a second telecommunications network, and a data storage device for storing data related to individual objects of the first telecommunications network, said first network manager being arranged to receive and transmit data according to a first network management information protocol, said second network manager being arranged to receive and transmit data according to a second network management information protocol, said data storage device comprising:

means for receiving data according to said first network management information protocol related to individual objects of the first telecommunications network from said first network manager;
means for converting the data received by the means for receiving data from a form used in the first network management information protocol into a form used in said second network management information protocol;
means for storing accumulated data related to individual objects of the first telecommunications network following its conversion by the means for converting data;
and
means for supplying data from the means for storing data related to the first telecommunications network according to said second network management information protocol to said second network manager.

A method of operating a network management system comprising a first network manager for a first telecommunications network, a second network manager for a second telecommunications network and a data storage device for storing data related to individual objects of the first telecommunications network, said first network manager being arranged to receive and transmit data according to a first network management information protocol, said second network manager being arranged to receive and transmit data according to a second network management information protocol, said method comprising the steps of:

receiving data according to said first network management information protocol related to individual objects of the first telecommunications network from said first network manager;
converting the received data from a form used in the first network management information protocol into a form used in said second network management information protocol and storing an accumulation of the converted data;
and
supplying the converted data related to the first telecommunications network according to the second network management information protocol to said second network manager.
