It is shown that abnormal traffic conditions lead to disorganization of the functioning of telecommunication subsystems in complex security systems. To ensure prompt and reliable detection of such situations in order to improve the quality of service, it is proposed to consider telecommunication systems in the form of complex, dynamic, stochastic systems. It is proposed to investigate their characteristics, which are manifested in the features of the observed message flow.

The purpose of the article is to develop an analytical model that allows describing the procedures for the formation of dynamic variables and reflecting the traffic states of telecommunication systems in the form of phase portraits, which in turn make it possible to conduct studies of these states. A model designed to describe the probabilistic behavior of traffic in telecommunication systems for various states is presented. The model is based on a recurrence relation that allows forming a two-dimensional vector of the state of the objects under study, taking into account a given matrix of transition probabilities. A particular model based on difference equations is also presented. The analytical model allows you to generate dynamic variables that reflect the state of the traffic under study. As a result, it became possible to analytically describe the behavior of a telecommunications system in its various states. The proposed approach, where traffic status information was considered as a dynamic system, made it possible to identify changes manifested through telecommunication systems by displaying dynamic variables in the form of a phase portrait. The research results have shown that the implementation of the proposed approach makes it possible to increase the efficiency and reliability of detecting abnormal traffic conditions that lead to disorganization of the work of telecommunications subsystems of integrated security systems.
