On implementing RRM/SON in virtualized multi-tenant small cell networks

Abstract

This paper addresses the implementation of Radio Resource Management (RRM) and Self-Organizing Networks (SON) functions in virtualized multi-tenant small cell networks. In this context, the deployment and operation of RRM/SON functions as virtualized services facilitates the customization of the Radio Access Network (RAN) on a per-tenant basis. Specifically, this paper develops the architectural and functional framework for virtualizing RRM/SON functions, together with the illustration of some examples assessing the orders of magnitude of the requirements of the involved Virtual Network Functions (VNF).
