IN-TINA architecture: integration or migration?

Research axis covered by TINA, which is considered as a long term telecom architecture solution, are the intelligent networks (IN), then telecommunication management network (TMN), the open distributed processing (ODP), the object oriented methodologies (OOA, OOD) and multimedia service aspects. The evolution of the IN towards TINA (migration and interworking) is currently subject of world-wide research. The long-term passage of the IN to TINA will depend on the success of migration studies and on the TINA demonstrations performance. In this framework, this paper does not propose an approach for migration nor interworking, but instead, it presents an integrated one that benefits from the advantages of the two IN-TINA architectures (capabilities, intelligence, real time, deployment…). This new architecture will satisfy the needs of new services creation and new techniques evolution
