Agustí delve into the crucial aspect of network slicing in 5G networks. Network slicing is identified as a pivotal feature that enables 5G networks to efficiently cater to a diverse range of applications and business entities. While strides have been made at the 3GPP specifications level in defining the architectural and functional aspects necessary for implementing network slicing in 5G networks, the development of management solutions for leveraging this feature within the Next Generation Radio Access Network (NG-RAN) remains at an early stage. The authors present a comprehensive framework aimed at managing network slicing within an NG-RAN infrastructure. This framework outlines the essential functions, interfaces, and information models required to automate the provisioning and management processes of RAN slicing effectively. A key contribution of their work is the proposal of an information model designed to describe the manageable characteristics and behavior of a RAN slice accurately. Furthermore, the authors discuss the applicability of their proposed framework in a neutral host provider scenario, illustrating how it can be implemented in real-world settings. Their research sheds light on the critical need for robust management solutions to fully exploit network slicing capabilities within 5G networks, paving the way for enhanced efficiency and performance across various applications and use cases. The paper has been submitted to IEEE for potential publication, underscoring its significance in advancing research efforts in this domain.
