In this paper we continue our research using the previously proposed analytical traffic model of a multidomain Next Generation Network (NGN), which is standardized for delivering multimedia services based on the IP Multimedia Subsystem (IMS). The aim of the model is to assess mean Call Set-up Delay (CSD) and mean Call Disengagement Delay (CDD), which are standardized call processing performance parameters. The output variables of the model are calculated for various types of intra- and inter-operator calls, taking into account a large set of network parameters large set and terminal registrations, which additionally load the network. To complete the previous research, in which the same parameters of the elements and traffic levels in both IMS/NGN domains (symmetric case) were assumed, in this paper asymmetric cases are investigated, in which selected parameters in one domain are different than in the other one. This allows to indicate the relations between parameters of one domain as well as mean CSD and mean CDD for calls originated in both domains.
