Leveraging Digital Twin Approach for Network Slicing in B5G Network

The Beyond5G (B5G) wireless technology will introduce diverse consumers and vertical applications with strict and real time connectivity requirements. Due to this proliferation of market needs 5G core network is evolving towards service based architecture. Therefore, this paper presents a novel approach to deploy B5G core network functions in a Digital Twin (DT) native application that can be scaled on demand with minimum effort while providing dedicated services, to satisfy the constraints of diverse verticals. In the proposed DT we deploy Open5GS which is an open source tool on oracle virtual box as virtual machine as a digital asset and emulate PDU sessions for multiple user equipment (UE) using open source emulator UERANSIM for digital counter part of gNodeB and UE. We analyzed the communication between different services classes of B5G core for dedicated slices in terms latency while keeping the packet loss at a minimum level. Our experiments have shown that by using DT approach the round trip time improved in all scenarios.
