5G Radio Access Network Slicing: System-Level Evaluation and Management

In 5G wireless networks, different types of services will be handled, including critical communications such as ultrareliable, low-latency communications (URLLC) and high-bit-rate communications [e.g. enhanced mobile broadband (eMBB) traffic]. To effectively handle such different types with diverse requirements, operators are working on network slicing concepts for dedicating resources to these services. As such, the purpose of this article is to design, develop, and validate mechanisms for creating and deciding on the dynamic resource allocation of network slices. Our proposed algorithm reconfigures and adjusts the slices so as to provide appropriate quality-of-service (QoS) levels toward mobile client nodes, and we evaluate its impact to resource usage and latency.
