Modelling Open Network Provision and Intelligent Networks

Abstract

The rapid evolution of network technologies and the opening up of public networks in Europe and world wide have resulted in a variety of different concepts and models for the future telecommunication world. Looking for a functional model for the flexible and open provision of future telecommunication services, also referred as value added services, a thorough analysis of the different proposed models is required in order to understand the implications of these models and their relationships. The relevant models identified are the Open Network Provision framework, the Intelligent Network concept and the OSI Reference Model and related distributed processing standards, The present paper proposes a compound functional model based on the above mentioned models forming a general framework for the provision of future services. Focussing on Intelligent Networks the paper identifies the alternatives of opening this level of network infrastructure to competiting service providers.
