Résumé : In the context of world economies transitioning to services, telecommunications services, as the primary means of communication between different economic entities, are essential. The focus on the end consumer, the convergence with the Internet, the separation between the software and the hardware implementing a service, and the telecommunications market deregulation have led to a revolution and a new era in the telecommunications industry. To meet these challenges, former national telecommunications providers have to reduce the construction time, from months to days, while affecting non-negatively other parameters (e.g., cost, quality of service, quality of experience) of new telecommunications services. To tackle this broad theme, we propose a telecommunications service construction process, software tools to be used in this process and a tool building process to build these tools. The telecommunications service construction process reflects current practices in the telecommunications industry. As such, it should be (easily) accepted by practitioners. The software tools (i.e., Domain Specific Modeling Languages designed as profiles of an Enterprise Architecture Modeling Language, graphical editors, code generators, Off the Shelf network simulators, a collaboration Design Rationale Domain Specific Modeling Language) contribute towards answering the challenges faced by telecommunications providers. The tool building process relies on models and provides a high automation degree, hence it allows building software tools more rapidly. We illustrate the telecommunications service construction process and the tools on a multimedia conferencing service. Our proposals contribute to reducing the construction time of new telecommunications services, while providing the possibility of improved quality of service and increased involvement of the consumer. Faster provisioning of new telecommunications services, that answer better to consumers’ needs, will increase the rate of development of new economic services in general, and will ultimately have a positive impac on world economic development.

Mots-clés : telecommunications services creation, model driven engineering, enterprise architecture, domain specific modeling language.
