В настоящей статье описана имитационная модель, а также численные результаты имитационного моделирования вероятностно-временных характеристик протокола управления доступом к беспроводной среде LTE-Advanced с агрегацией нескольких несущих частот. Продемонстрированы характеристики среднего времени задержки и вероятности входных потерь в буфере базовой станции в зависимости от интенсивности входной нагрузки. Результаты данного исследования могут быть использованы производителями оборудования мобильных сетей 4-го поколения с целью анализа и оптимизации показателей качества сетей.

In this paper, the simulation model and numerical results of simulation of the probability-time characteristics of LTE-Advanced wireless medium access control protocol with carrier aggregation support are described. The characteristics of packet delay time and buffer loss probability depending on input load intensity are demonstrated. The results of the investigation can be used by 4th generation mobile vendors for network quality indicators analysis and optimization.
