Virtual network functions in eLTE digital trunking network

Abstract

Movitel, in the process of migration to digital trunked radio systems, aims to provide broadband services with the deployment of a fourth generation network, to achieve this it will be necessary to implement new tools and develop applications that complement the functionalities of the system. This paper will address some of the solutions for broadband data transmission that Movitel has implemented on the Huawei eLTE network through the nationwide deployment process, taking advantage of the concepts of virtualized networks and software-defined networks. The research structure is the analysis of eLTE technology as a mobile communications system, the analysis of the architectures of the NFV systems, the experimental tests carried out with the terminal equipment for access and the functionalities of the system where the virtualization concepts of network functions were applied. Finally, the final scheme of the connectivity solution developed through the implementation of virtual systems and the possibilities of service models in comparison to emerging technologies for mobile broadband data transmission is presented.
