Background. An increase in the number of users and services with the support of the required quality of service, an increase in the coverage area of one operator’s radio access network, and most importantly, the emergence of packet-switched technologies and systems, has led to a significant complication of the core mobile communications network and its nodes, an increase in the functionality and intellectualization of the network core. Gradually, it was the core network and the technologies of its functioning that became more significant than the radio access network. Hence, for the construction of
mobile communication systems, more integrated information and telecommunication technologies, especially from the field of network and information technologies, became popular.
Objective. The aim of the paper is to present the concept of the architecture of mobile infocommunication systems as systems whose services make a significant, even decisive, contribution to the functioning of the infrastructure of modern society, built on the constant exchange and assimilation of information.
Methods. The structural and functional methods of constructing the architectures of information and telecommunication systems are investigated.
Results. The signaling network of mobile infocommunications manages the maintenance of both individual wireless user terminals (telephones, smartphones, tablets), and many wireless inter-machine communication devices and the Internet of Things. In addition, the same alarm system supports various telecommunication networks of wireless subscriber access, automobile and other vehicles; creates an interface with wired / cable access networks. Thus, the core network of mobile infocommunications can fully integrate interfaces with all types of telecommunications, which are designed to transmit many low-speed data streams, as well as to transmit high-speed data streams. There is a
tendency to take over traditional old services, for example, the public telephone network and radio-relay communication lines, and turn them into private services of the mobile infocommunication network, which further enhances their importance. All this creates the prerequisites for the transformation of mobile infocommunication operator systems into the main (determining)
players in the telecommunications market. Confirmation of this is the high characteristics that are to be achieved in the networks of the 5th and 6th generations of mobile infocommunications.
Conclusions. Mobile infocommunication systems have become a defining component of all telecommunication services provided to users and non-servicing nodes of sensor networks, and the infrastructure of core networks and access networks of mobile infocommunications has begun to determine the general technical infrastructure of telecommunications
