Soft Resource Slicing for Industrial Mixed Traffic in 5G Networks

This letter proposes a dynamic switching soft slicing strategy for industrial mixed traffic in 5G networks. Considering two types of traffic, periodic delay-sensitive (PDS) traffic and sporadic delay-tolerant (SDT) traffic, we design a dynamic switching strategy based on a traffic-QoS-aware soft slicing (TQASS) scheme and a resource-efficiency-aware soft slicing (REASS) scheme. The proposed strategy ensures the reliability of PDS traffic under delay constraints, while dynamically allocating remaining resources to SDT traffic. Simulation results show that the proposed soft slicing strategy out-performs existing works in meeting the strict QoS requirements of industrial mixed traffic.
