This paper proposes an approach to solve the problem of LTE EPS network parametric synthesis taking into account self-similar properties of multiservice traffic. The problem is solved with the known source data such as network topology, traffic routes, statistical data on the demand for information and communication services. The article proposes the calculation expressions to determine the parameters of multiservice self-similar traffic coming into the network, as well as aggregation of in different network elements. The solution is based on the representation of self-similar traffic as of fractal Brownian motion model and calculation expressions Offed by Norros. The proposed method in the paper was compared with the method based on the classical model of a Poisson flow. The experimental procedure is to calculate the parameters of the network by both methods and then checking the results of calculations using the simulation model. The analysis found that the use of the proposed method reduced the average delay time by 7-14%. The results of the simulation confirmed the results of analytical modeling, evidence of the adequacy of the models that have been used.
