The rapid development of multiservice communication networks using the architectural concept of NGN (Next Generation Network) requires the creation of an adequate mathematical model of the quality of the functioning of signaling systems based on the IMS (IP Multimedia Subsystem) multimedia communication subsystem, which are switching nodes of NGN / IMS networks when establishing a connection and providing multimedia communication. Here, multimedia communication refers to the organization of telephone connections, video conferencing, the transmission of multimedia information, as well as Triple Play services, including voice services, Internet access and watching television programs. The following article is devoted to the study of characteristics of signal traffic in a communication network based on the IMS system.
