Детально исследован каждый элемент, что повысило точность предлагаемой методики. В соответствии с Марковской моделью БС представлена как система, в которой учтены все возможные состояния. Построены модели для БС с двумя и тремя пучками каналов. Параметры каждого функционального элемента модели могут быть получены с помощью наблюдения в течение определённого периода времени. Решение системы уравнений для каждой из приведённых в статье моделей позволит получить значения нахождения системы в определённом состоянии. Полученные характеристики можно использовать для расчёта надёжности всей сети радиосвязи, а в итоге для оценки качества обслуживания абонентов этой сети.</p><p>Сделаны выводы о возможностях применения полученных моделей при проектировании новых и расчёте показателей качества существующих сетей связи железнодорожного транспорта. Предложенные модели могут применяться не только для сетей радиосвязи железнодорожного транспорта, но и для сетей подвижной связи коммерческих операторов. </p></abstract><trans-abstract xml:lang="en"><p>Base station (BS) is a terminal device of a radio communication network, while railway radio communications play an important role in ensuring safety of passenger and cargo transportation.</p><p>A proposed method for calculating the performance of base stations in railway digital radio communication networks is intended to calculate for the BS the probabilities of being in certain state.</p><p>BS was decomposed and such functional elements as circuit groups and a radio frequency path were identified, as well as the central module ensuring the exchange of information with elements of this BS and with other BSs. A detailed study of each element has increased accuracy of the proposed method. Following the Markov model, BS is presented as a system in which all possible states are considered. Models for BS with two and three circuit groups have been constructed. The parameters of each functional element of the model can be obtained through observation over a certain period. The solution of the system of equations for each of the models presented in the article will allow obtaining the values of the system being in a certain state. The obtained characteristics can be used to calculate the reliability of the entire radio communication network, and then to assess quality of service provided to the users of this network.</p><p>Conclusions are made about the possibilities of using the obtained models when designing new railway communication networks and when calculating quality indices of existing ones. The proposed models can be applied not only to railway radio communication networks but also to mobile communication networks of commercial operators. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>цифровая сеть радиосвязи</kwd><kwd>телекоммуникационные системы железнодорожного транспорта</kwd><kwd>качество обслуживания вызовов</kwd><kwd>безопасность движения поездов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>digital radio communication network</kwd><kwd>railway telecommunication systems</kwd><kwd>call quality</kwd><kwd>train traffic safety</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Elbahhar Boukour, F., Heddebaut, M.
