Zusammenfassung
In 1997, the SDL-pattern approach has been introduced to the  scientific community. Since then, the approach has been improved in many  ways. In particular, the pattern pool has been extended to cover a variety of  distributed systems and communication protocols, a notation to define patterns  has been added, and the methodology for pattern-based system design has been  refined. Based on the results of more recent case studies, the approach has been  assessed as consolidated, and is currently being transferred to industry. In this  paper, we present our experience of applying the SDL-pattern approach in an  industrial environment, the development of a UMTS call processing system, a  part of the Radio Network Controller (RNC). Furthermore, the benefits of  applying the approach are evaluated in this context and quantified.
