A Novel Network Slice Admission Control Scheme in 5G-V2X Communication

Network slicing is a prominent solution to support 5G-V2X communication challenges. It provides the ability to create multiple logical networks on the same infrastructure to support various use cases of 5G-V2X communication. It also provides business opportunities to the service provider. In this paper, we present an efficient network slice admission scheme that utilizes Radio Access Network (RAN) resource availability. This scheme aims to enhance service provider revenue while ensuring Quality of Service (QoS) for users. We evaluated our proposed scheme by comparing it with two resource scheduling schemes called reserved scheduling and priority scheduling commonly employed for network slice admission. Comparison results show that our scheme shows a superior acceptance rate for new inflexible requests, outperforming reserved and priority scheduling. Additionally, it achieves higher revenue for service providers than the reserved scheme and demonstrates superior resource utilization for both inflexible and flexible slices.
