Abstract:
Network slicing for 5th Generation (5G) networks enables the support of multiple logical networks, called slices, which aim to be tailor-cut network solutions for specific services for the vertical industries (e.g., transportation, smart factories, health industry etc.). Although, considerable effort has been taken to define the generic framework for network slices, it still remains open how the network performance can be further optimized by taking into consideration the specificities of each use case. At the same time, the work for the specification of network functions to support autonomous driving is picking up speed. However, up to this moment, it is still not addressed how contextual information can serve the optimization of a vehicle-to-everything (V2X) slice. This paper provides in detail the latest status of the 3GPP standardization process related to slicing. It also introduces two new mechanisms called Context Enhanced MOBility management (CEMOB) and Context-Aware Resource Pre-allocation (CARP). The former improves the existing mobility management process while the latter serves the minimization of the communication delay among vehicles. The point we make with these two mechanisms is that by taking advantage of contextual information the performance of network control functions can be significantly improved. Towards this end, we quantify the merits of our mechanisms and we present how these are integrated into a V2X slice.
