In the modern world requirements for accurate and fast information distribution are becoming more and more important, which creates a strong necessity for appropriate telecommunication network architecture. Proposition of such an architecture is the Next Generation Network (NGN) concept, which in order to guarantee Quality of Service (QoS), should be correctly designed and dimensioned. For this reason proper traffic models must be proposed, which should be efficient and also simple enough for practical applications. In the paper such a traffic model of a single domain of NGN architecture based on the IP Multimedia Subsystem (IMS) concept is proposed, which allows to evaluate mean Call Setup Delay (CSD) and mean Call Disengagement Delay (CDD), a subset of call processing performance parameters defined by International Telecommunication Union Telecommu-nication Standardization Sector (ITU-T). Using the model basic relationships between network parameters and call processing performance are investigated and presented. All obtained results are verified using simulations, which confirm correctness and usefulness of the proposed model.
