Background. Network slicing (NS) enables multiple logical slices over shared infrastructure but faces challenges in managing heterogeneous traffic (streaming vs. elastic) with conflicting QoS requirements. Purpose. This paper proposes a radio admission control (RAC) scheme with priority service interruption for a two-slice 5G network to balance GBR for streaming traffic and efficient non-GBR elastic traffic service. Method. A two-dimensional Markov model is developed. Streaming traffic requires fixed resources; elastic traffic has state-dependent service rate. A full interruption scenario is implemented where elastic traffic preempts streaming traffic within the second slice's guaranteed capacity. Stationary probabilities are obtained numerically. Results. As streaming traffic arrival rate increases, elastic traffic interruption probability rises sharply then stabilises. Mean numbers of served requests converge to guaranteed capacities. Elastic traffic blocking remains nearly constant. Conclusions. The proposed RAC scheme captures the streaming-elastic trade-off in sliced networks. The full interruption mechanism prioritises elastic traffic under high load. The model provides quantitative guidelines for tuning guaranteed capacities in 5G/6G systems.

Предпосылки. Технология сетевой нарезки (NS) позволяет создавать логические слои в рамках общей сетевой инфраструктуры, но сталкивается с проблемой совместного обслуживания разнородного трафика (потокового и эластичного), предъявляющего различные требования к QoS. Цель. Разработать и провести анализ схемы управления доступом к радиоресурсам с приоритетным обслуживанием в сети 5G с двумя слоями, которая позволит обеспечить баланс между требованиями к обслуживанию потокового и эластичного трафика. Метод. Использованы методы теории массового обслуживания. Разработана двумерная марковская модель. Потоковый трафик предъявляет фиксированное требование к ресурсам; для эластичного трафика требование к ресурсам зависит от состояния системы. Реализован сценарий полного освобождения гарантированной эластичному трафику емкости. Распределение вероятностей состояний системы получено численно. Результаты. С ростом интенсивности поступления потокового трафика вероятность прерывания передачи эластичного трафика сначала резко возрастает, затем стабилизируется. Среднее число обслуживаемых запросов стремится к гарантированным числам. Вероятность блокировки эластичного трафика почти не меняется. Выводы. Предложенная схема доступа к ресурсам сети представляет собой компромисс при обслуживании разных типов трафика. Модель позволяет получить количественные рекомендации для настройки гарантированных емкостей в системах 5G/6G.
