Communication network management system for automatically converting action parameters to network technology dependent parameters using a selected conversion rule conforming to a network technology

A communication network system for converting action parameters contained in policy information obtained by abstracting network-related user requirements to parameters conforming to network technology and type of network element, and setting these parameters in the network element, said system comprising:

• first conversion means for converting action parameters contained in the abstracted policy information to network-technology dependent parameters;
• and
• second conversion means for converting the network-technology dependent parameters to parameters dependent upon a type of network element and setting the converted network-technology dependent parameters in the network element,
• wherein said first conversion means includes:
• policy disassembling means for disassembling the abstracted policy information, extracting the action parameters and outputting the action parameters;
• conversion-rule storage means for storing conversion rules used when the action parameters are converted to network-technology-dependent parameters;
• and
• conversion means for selecting a conversion rule conforming to a network technology and converting the action parameters to network-technology-dependent parameters using the selected conversion rule.
