TMN-based intelligent network number portability service management system using CORBA

Local number portability (LNP) is an intelligent network (IN) service, which provides end users the ability to change local telephone service providers without changing their telephone numbers. LNP is a key service for increasing competition in the local telephone marketplace. To implement LNP, a number portability administration center (NPAC) is needed to manage the LNP databases. Service providers also must implement the carrier-level system and update their existing IN components to provide LNP. In this paper, we present our work on applying the TMN and CORBA technology to the service management of the intelligent network, particularly the LNP. We propose a TMN-based LNP system architecture and present a design and implementation of a NPAC service management system using CORBA.
