Evaluating Open Service Access with an Abstract Model of NGN Functions

摘要

As new business models and market opportunities are rapidly emerging from the 'opening up' of telecommunications networks, we required a better understanding of the effectiveness of using open standards to provide access to functions in NGNs. In this paper we reason about the coverage of openly accessible functions using an abstract model of NGN functionality. Defining and using an abstract model allows us to evaluate the effectiveness of open standards from a perspective where a wide range of NGN functionality can be generalised and conveniently categorised. Subsequently, it will be possible to identify the gaps, which are a subset of functionality that we are specifically interested in for our project.
