PROPOSAL FOR THE IMPLEMENTATION OF THE CORE OF A VIRTUALIZED LTE MOBILE NETWORK
Abstract
The purpose of this work is to present a proposal for the virtualization of the core of the LTE network using free software. To do this, we start from the fundamental characteristics of LTE mobile networks, focusing on the details of the network core at the user plane and control plane. Next, two free software projects that are based on the implementation of the virtualized network core (Magma Core and OMEC) are analyzed, and applying comparative methods, the most appropriate is selected. As a result, it is obtained that the Magma Core solution is the most suitable for the implementation of the virtualized LTE network core due to the results obtained in a set of indicators, highlighting the flexibility of its architecture, its best efficiency/cost ratio and its possibility of deployment. as the core of an LTE network in different scenarios. Finally, the AGW (Access Gateway) component of the chosen solution (Magma Core) that represents an Evolved Packet Core (EPC) was implemented in a virtual laboratory environment, which allowed us to verify its possibilities as a virtualized EPC.
