Abstract

UML-RT offers a set of extensions to the UML, which are a basis for modeling real-time systems. Some investigations have shown that UML-RT provides concepts, which are close to the constructs used at Ericsson for designing mobile switching systems in the GSM (Global System for Mobile Communication) telecommunication domain. Telecommunication systems are some of the most challenging systems regarding size, complexity, and real-time constraints. This article describes the main constructs used at Ericsson, which display a robust framework for building real-time systems; and shows the mapping to UML-RT. An addition to UML-RT is presented; it allows UML-RT to be a candidate for modeling embedded real-time systems in the telecommunication domain.
