Abstract
The paper proposes the simulation macro model of subscribers’ behavior in cellular communications network, considering its structure, peculiarities of the subscribers’ movement and their activity, including the requests generation process by subscribers’ terminals. Model input obtains the set of cellular structure parameters, simulation interval, parameters of the user’s requests flow, number or caller groups by moving speed and maximum possible speed of subscribers. The results of the simulation are: generated according to the set rules cellular structure of the base stations, which are located in the center of hexagonal cells, the capacity of the network in terms of calls, generated subscriber’s requests in the range of simulation interval, characteristics of their processing and the number of non-processed requests in the reason of network congestion considering the subscribers movement. The continuous hexagonal coverage of a given area with lowest possible ceiling and the maximal distances between neighboring base stations according with their cell ranges is received based on the proposed method of forming the cellular structure of mobile network received. It shows the number of base stations, their location. Based on subscriber’s movement simulation we define a set of coordinates of each subscriber location at any simulation step. These coordinates depict different scenarios of subscribers moving that consist of individual trajectories for each subscriber considering their personal speed and movement direction. The amount of required equipment to service the subscriber load entering the coverage zone may be calculated based on simulation results.
