Abstract
Service control and management of IMT-2000 should be flexible and scalable to make an easy introduction of multimedia services from various service providers. It requires the extension of IN control capabilities for multimedia service provisioning and integration of TMN service management functions and IN functional entities. In this paper, we propose the architecture for the integration of TMN and IN functions using CORBA technology especially focusing on control and management of the IMT-2000 global roaming service. The IN service data function is integrated into TMN management information bases (MIB) for the centralization of customer profile management. Network to network interface (NNI) signaling information flows of service management are integrated with intersystem management information flows across the TMN X interface for the integrated control and management. Management operation flows and the interface for automatic establishment of global roaming agreement have been designed using CORBA IDL. Service management applications, the CORBA/IN interworking function and the CORBA/TMN gateway to support backward compatibility with legacy TMN and IN functional entities have also been designed.
