The Research And Implementation Of Element Management System In China Telecom MBOSS System

The operational mode of telecommunication operators has transferred from service-centered to customer-centered, with the opening up of global telecom service. Customer services will become the next competitive focus among the telecommunication companies. To satisfy the customer has come in the spotlight of these companies.Under this circumstance, Telecom Management Forum brought forward the Next Generation Operation System and Software, i.e. NGOSS. Based on the analyses of central operation flow from service providers, the researchers extracted the operation flow and the main technology of OSS. Then they came up with the NGOSS system. It's a framework which can support the current operation and at the time transfer to the customer-centered OSS system. CTG-MBOSS system is a new generation of enterprise management, business, operation and supporting system proposed by China Telecom Group according to the NGOSS standards. As the basic of CTG-MBOSS system, element management system has to be rebuilt and adjusted on functions, interfaces, data model and so on.This thesis aims to discuss the direction and methods of element management system improvement. This thesis analyses UniView DA network management platform completely as an element management system, and suggests several aspects to improve. The conclusion and perspectives are based on the research on element management system during the author's internship in GW Technologies, the theory basis of TMN and eTOM models, the suggestions on constructing MBOSS system and the requirement analysis on element management system using MPDS methodology.Firstly, the theories of TMN model defined by ITU-T and NGOSS defined by TMF are introduced. After knowing where it comes from and what the main technology it contains, the eTOM model, the system framework and related methodology of CTG-MBOSS system are presented.Then, starting from the definition of element management system, the position of element management system in eTOM model and CTG-MBOSS system is defined based on the eTOM model theory according to CTG-MBOSS system framework and methodology. The requirements analysis of element management system is concluded by the fundamental theory of MPDS methodology.Finally, the UniView DA platform is analyzed using MPDS methodology. The direction and methods of system improvement are proposed according to the requirements analysis conclusion.
