Abstract
To meet the requirements of assorted applications from different service providers operating on a shared infrastructure, the current generation of mobile cellular networks (5G) rely on network slicing. However, the synchronization of RAN and core network slicing has not been investigated as an interdependent resource allocation problem. This paper proposes a novel End to End (E2E) resource slicing and allocation scheme. The Slice to Node Access Factor (SNAF) based E2E Slice resource provisioning scheme is proposed based on diverse users' Quality of Service (QoS) requirements for transmission delay and data rate. The SNAF, in principle, ensures proper resource provisioning and traffic synchronization, and thus allocates radio resources based on the provisioned affordable traffic and backhaul resources, and vice versa. Based on the 5G air interface, we ran a system-level simulation to assess the performance of our solution from multiple angles. Simulation findings show that our proposed SNAF-based interdependent E2E resource allocation delivers improved E2E traffic-resource synchronization and enhances QoS satisfaction with minimum resource utilization when compared to benchmarked state-of-the-art methods.
