Abstract:
Network slicing is one of the key technologies of fifth generation wireless networks with an ever-increasing number of users and services. A feature of this technology is the ability to organize logically isolated segments of radio resources for the specific requirements of the operator and its users, and the redistribution of the resource volumes between the segments is possible, but only at the moments of the controller accessing them. In this work, a mathematical model is built for two classes of impatient elastic traffic with a minimum rate guarantee transmission by queuing system with queues and signals that control resource redistribution. Formulas are given for calculating the parameters of the efficiency of resource redistribution — the coefficient of compliance with the initial distribution of the resource, the success rate of resource redistribution, and the coefficient of resource utilization.
Keywords:5G, network slicing, queuing system with signals, dynamic resource allocation, elastic traffic.
