METHOD AND NETWORK MANAGEMENT APPARATUS FOR IMPLEMENTING INFORMATION SERVICE LEVEL INHERITANCE IN NETWORK MANAGEMENT SYSTEM

A method for implementing Information Service (IS) level inheritance in a network management system includes: defining a WSDL file for an inheriting IRP, including the base management operations of the base IRP in the WSDL file for the inheriting IRP during the defining action to establish the IS level inheritance between the inheriting IRP and the base IRP; implementing conversion between a base management operation message and a SOAP format message according to the IS level inheritance. Apparatuses and other methods for implementing IS level inheritance are disclosed as well. The solution enables the inheriting IRP module of the network management apparatus to correctly execute the base management operation by establishing the IS level inheritance between the inheriting IRP and the base IRP, which meets the IS level description requirement of the IRP.
