5G Network Slicing for Vehicle-to-Everything Services

TLDR

5G networks target diverse vertical markets, necessitating multiple programmable network slices, each comprising tailored logical functions and configurations to meet specific service requirements. The article proposes a vision for designing 5G network slices tailored to vehicle‑to‑everything services, aiming to enhance transport fluidity, safety, and comfort while outlining the technological options, enablers, concerns, and challenges for their successful deployment. The proposed slicing solutions partition core network and radio access resources and configure vehicular end‑device functions to support diverse vehicle‑to‑everything use cases.

Abstract

The multitude of key vertical markets targeted by 5G networks calls for the support of multiple network slices on a common and programmable infrastructure. A network slice is intended as a collection of logical network functions and parameter configurations tailored to support the requirements of a particular service. In this article, we present our vision on the design of 5G network slice(s) customized for vehicle-to-everything services, which involve vehicles exchanging data with each other, with the infrastructure and any communicating entity for improved transport fluidity, safety, and comfort on the road. The suggested slicing solutions involve the partition(s) of the core network and the radio access network resources, as well as configuration of the vehicular end-device functionality, to support different vehicle-to-everything use cases. This research article aims to elaborate on the technological options and enablers, concerns, and challenges for the succesful deployment of 5G slice(s) for multitenant vehicle-to-everything services.
