Slice scheduling for industrial time-critical services in 5G TSN integration network

Abstract

The integrated deployment of 5G and time sensitive network (TSN) is an important foundation for realizing wireless industrial Internet and flexible manufacturing. How to guarantee the high-quality transmission simultaneously of diverse industrial services and mobile services is a key issue to be solved for 5G TSN integration. Therefore, the types of industrial services were divided according to the differences in requirement characteristics, a slice scheduling strategy for industrial Internet was designed to satisfy the requirements of periodic time-critical services and sporadic burst services, and a resource partitioning algorithm based on uniform distribution was proposed. By controlling resource reservation and resource preemption, the proposed method can optimize the utilization of wireless resources and guarantee the delay of industrial traffic and the transmission rate of mobile services. Finally, the effectiveness of the proposed method in improving the service requirements satisfaction and resource utilization was verified by simulation experiments.
