Virtualización de una central telefónica celular 4G como preparación para convivencia con red celular 5G.

Abstract

This paper analyzes and studies the development and progress of telecommunications, specifically related to mobile telephony with its imminent migration of 4G networks to 5G networks. Due to the change in the profile of the subscriber of being a consumer of voice services networks towards the high consumption of data services immersed in the flow of the internet of things, cellular networks have to adapt and provide a dynamic response to such changes. It is for this reason that new virtualization concepts of equipment and networks defined by software are adopted in a cellular network operation. In the development of this work the concepts of Network function virtualization (NFV), software defined networks, SoftwareDefined Networking (SDN) and Cloudification are developed, applied to a cellular network when designing a basic network to integrate to a 5G network. The methodology used for this work is exploratory, descriptive with an experimental approach, that allows to obtain a capacity of 3.5M users in VLR, 1.6M active context and 10Gbps throughput in just 2 redundant cabinets.
