摘要:

5G与时间敏感网络(time sensitive network,TSN)融合部署是实现工业互联网无线化和柔性制造的重要基础,如何实现多类型工业业务和移动业务的共网高质量传输,是5G TSN融合网络需要解决的关键问题。为此,面向工业互联网场景,依据业务特征差异划分工业业务流的类型,设计了一种适配周期性时敏业务和突发性时敏业务的网络切片资源调度策略,提出了基于均匀分布的资源分区调度算法。所提方法通过控制资源预留和资源抢占,在优化无线资源使用的同时,保障了工业业务流的时延,满足了移动业务的传输速率需求。最后,通过仿真实验验证了所提方法在提升业务需求满足度和资源利用率方面的有效性。

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.

Key words: 5G-TSN integration network, resource scheduling, network slicing, time-critical service
