Patent ID: 7010615

Claim:
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.
