A Pre-emptive Scheduling Mechanism for Service Assurance of Network Slicing in Next Generation Cellular Networks

As the number of services and applications with diverse requirements keeps increasing, it is therefore of paramount importance to develop more efficient resource allocation techniques. In this paper, we propose a pre-emptive scheduling mechanism for managing network slices, specifically enhanced Mobile Broadband (eMBB) and Ultra-Reliable Low-Latency Communications (URLLC), in 5G and beyond (5GB) networks, leveraging network slicing to optimize resource management. The proposed mechanism effectively balances the trade-off among throughput, latency, and reliability by dynamically reallocating limited radio resources between two slices. Through system-level simulations, we demonstrate that the stringent latency requirements of the URLLC slice are satisfied while minimizing the eMBB throughput degradation. The simulation results indicate that, compared to traditional resource allocation techniques, the puncturing mechanism enhances resource utilization, offering a scalable solution for the latency and throughput requirements of 5GB networks.
