This paper discusses an architecture to cope with the technical complexity of the global system resulting from the world-wide interworking of mobile and fixed networks of different technologies, for the provision of multimedia services, in a liberalised and deregulated environment. The architecture represents the convergence of two frameworks that had progressed independently until the mid 1990s: (a) service architectures for a global information infrastructure; and (b) mobile communications systems. The need for the convergence of mobile and fixed networks at service control and management level is a key issue in the telecommunications environment. The existence of a generic service layer spanning a set of heterogeneous networks (fixed and wireless) promises several advantages for greater flexibility and efficiency in service development and deployment, compared to those obtainable with network-specific service creation practice. The TINA-C has established an architecture that has the potential and momentum to respond to such challenges. However, several adjustments and refinements in both the TINA network and services architectures appear necessary when addressing mobility. The approach presented here was envisaged by the EC/ACTS research project DOLMEN, which took as a basis the TINA architecture and enhanced it in the perspective of world-wide mobility service provisioning in a multi-provider environment. The paper shows how requirements stemming from personal mobility and terminal mobility are reflected in relevant changes and extensions of TINA, namely: a new Business Model (including also the role of Terminal Provider), two new computational components (User Agent Home and User Agent Visited), the concept of Retailer Federation, new ways to model and manage terminal mobility at CORBA level (the DPE model chosen by TINA) by means of ad-hoc defined interoperability bridges and new object referencing schemes, and finally, suitable models to represent handover in the TINA Network Resource Architecture.
