Requirements represent an important aspect of telecommunications standards, whether they apply to protocols, services, or architectures. This paper presents an overview of the proposed ITU-T Recommendation Z.151 – User Requirements Notation (URN), intended for the elicitation, analysis, specification, and validation of requirements. URN combines modelling concepts and notations for goals and intentions (mainly for non-functional requirements, quality attributes, and reasoning about alternatives) and scenarios (mainly for operational requirements, functional requirements, and performance and architectural reasoning). Basic concepts and notation elements are introduced, together with the main requirements analysis, transformation, and management techniques relevant to URN and supported by the jUCMNav Eclipse plug-in. Although URN is generally suitable for describing most types of reactive systems and information systems, we will illustrate its applicability to the development of telecommunications standards. Other applications of URN will briefly be enumerated, and an overview of future extensions to URN will be presented.
