A new era is opening for the world of information and communication technologies with the 5G networks’ release. Indeed 5G networks appear in modern wireless systems as solutions to “traditional” networks’ inflexibility and lack of radio resources problems. Using these networks the operators can expand their services’ range at will and, therefore, manage daily operations by monitoring ‘key performance indicators’ (KPIs) - helping meet the quality of service (QoS) requirements much easily. To meet the QoS requirements 5G networks can be implemented alongside priority scheduling algorithms. This paper considers the operation of a wireless network slicing model under two scheduling algorithms. A comparative analysis of main performance measures is provided.

Переход к беспроводным сетям пятого поколения 5G ознаменовал новый этап развития информационных и коммуникационных технологий. Сети пятого поколения должны решить такие проблемы, как негибкость «традиционных» сетей и нехватка частотных радиоресурсов для качественного предоставления услуг. Предполагается, что, используя эти сети, мобильные операторы смогут значительно расширить спектр услуг и обеспечить требуемое качество их предоставления. Для удовлетворения требований к качеству обслуживания ( англ. Quality of Service - QoS) операторам необходимо выполнение «ключевых показателей эффективности» ( англ. Key Performance Indicators - KPI), описанных в стандартах связи. Для этой цели могут быть использованы алгоритмы приоритетного облуживания. В статье рассмотрена модель беспроводной сети 5G, поддерживающая технологию нарезки сети и реализующая управление доступом к сетевым радиоресурсам при помощи введения приоритетов. Изучена работа модели в рамках двух алгоритмов. Проведён сравнительный анализ основных показателей эффективности модели.
