Increasing complexity in telecommunications services requires ever more complex standards, and therefore the need for better means to write them. Over the years, scenario-driven approaches have been introduced in order to describe functional aspects of systems at several levels of abstraction. Their application to early stages of design and standardization processes raises new hopes in editing concise, descriptive, maintainable, and consistent documents that need to be understood by a variety of readers. In this context, this paper investigates a recent visual notation for causal scenarios called Use Case Maps. The goal is to better describe distributed systems and telecommunication standards, and to fill the gap between the stage where services are described informally and the stage where message sequence information is generated. As an example, this paper focuses on the Incoming Call Screening service of the new Wireless Intelligent Network standard.
