SPECIFICATION DESCRIPTION SUPPORTING METHOD OF TELECOMMUNICATIONS NETWORKS MANAGEMENT USING INFORMATION MODEL AND PROCESS MODEL

Managed Objects (MOs) can be specified by the combination of a static information model and a dynamic process model. First, this paper prese nts a mapping of attributes from a process model diagram to an informa tion model diagram. Then, it introduces a concept of topology into the se two models and proposes a hypothesis about the relationship of topo logy in these two models. To explicitly explain the hypothesis, it can be stated that all attributes of incoming or outgoing data related to a process in a process model are mapped to an information model where these attributes are interconnected by an explicit relationship which corresponds to a specific meaning, such as physical containment or lo gical connection. From an intuitive perspective, it can be said that i f two attributes have a close topological relationship in a process mo del, the mapped attributes also have a close topological relationship in an information model. This hypothesis provides clues for determinin g whether there is an error in an attribute either in the process mode l or in the information model. By examining the way attributes of inco ming or outgoing data related to a process are mapped to an informatio n model, we can detect whether there is an error with respect to the p rocess. The error correction is performed with the assistance of proba bility analysis. The method of error detection and correction can be i mplemented in a computer aided tool. Then, error detection on the attr ibute level becomes automatic, and error correction on the attribute l evel becomes interactive through the computer aided tool. Finally, the validity of the hypothesis is confirmed by analyzing ITU-T Recommenda tion M.3100. The specification of the fabric object class defined in M .3100 is transformed into these two models and the hypothesis is valid ated for the analysis of the mapping between these two models.
