Service Based Virtual RAN Architecture for Next Generation Cellular Systems

Service based architecture (SBA) is a paradigm shift from Service-Oriented Architecture (SOA) to microservices, combining their principles. Network virtualization enables the application of SBA in cellular systems. To better guide software design this virtualized system with SBA, paper presents perspective and positional approach using fundamental development principles for adapting Radio Access Networks (vRANs). First, we present motivation an radio Then, explore critical requirements, key principles, components provide services SBA. We also potential applying SBA-based (RAN) by comparing functional split requirements 5G RAN existing open-source accelerated hardware implementations service bus, discuss limitations Finally, some discussions, future directions, roadmap such high-level next-generation infrastructure.
