The virtualized radio access network (vRAN) could implement virtualized baseband functions on general-purpose platforms and expand the processing capacity of the radio access network (RAN) significantly. In this paper, a Not Only Stack (NO Stack) based vRAN is proposed to be employed in the fifth generation (5G) mobile communication system. It adopts advanced virtualization technologies to maintain flexible and sustainable. The baseband processing and storage resources should be sliced and orchestrated agilely to support multi radio access technology (multi RAT). Also it is analyzed and demonstrated by different use cases to validate the benefits. The proposed vRAN reduces signaling overheads and service response time in the bearer establishment procedure. Concluded from the analyses and demonstrations, the NO Stack based vRAN could support multi-RAT convergence and flexible networking effectively.
