Modeling IMS Service Sharing System using Petri nets

Presented paper introduces simulation model and simulation results of previously proposed Service Sharing System (SSS). SSS deployed in a network of interconnected IP Multimedia Subsystem (IMS) domains enables operators to offer variety of services provided by different 3^rd party providers to their customers as well as to offer operator´s own services in new markets - to customers of other operators. Based on simple idea of transferring necessary service-related information throughout network of interconnected operators the SSS is modeled using modular colored stochastic Petri nets.
