Toward Radio Access Network Slicing Enforcement in Multi-cell 5G System

Abstract

The proliferation of sophisticated applications and services comes with diverse performance requirements. The 5G cellular network is advocated to support this diversity through an end-to-end network slicing. Even though the slicing is not a novel concept, its implementation in the RAN still remains challenging. In this article, we aim to enforce the real time 5G slicing from radio resources perspective in a multi-cell system. For that, two exact optimization models are proposed. Due to their high convergence time, three heuristics are developed and evaluated with the optimal models. Results are promising, as two heuristics are highly enforcing the real time RAN slicing.

Design of a 5G Experimental Platform Based on OpenAirInterface

“…For this reason, a significant effort has to be provided for optimizing the codes, but also by optimizing some of the normalized 5G mechanisms and protocols. This is the case for instance for 5G resources allocation [4]. Optimizing 5G mechanisms and protocol is part of our future works.…”

Optimizing the Energy Efficiency Using Quantum Based Load Balancing in Open Radio Access Networks

“…To effectively manage the limitations and minimise expenses, it is crucial to initiate a network redesign process that focuses on improving the efficiency of RAN installations and streamlining the operational aspects of RAN network services, as proposed in the study by [24]. The authors of [25] proposed an end-to-end network slicing method in multi-cell system. Nevertheless, the application of this technology in the RAN continues to provide significant challenges.…”
