Prototipos de redes lte en base a tecnología de radio definida por software e integración de la tecnología de radio sobre fibra en redes móviles : simulación de una red lte utilizando el proyecto srsran.

Abstract

The purpose of this curricular integration work is to simulate the elements that make up the architecture of an LTE network (Long Term Evolution) through the srsRAN platform, which is useful for the study and analysis of the elements that make up a fourth-generation cellular network. Whether for academic or commercial environments. The srsRAN platform allows to implement each of the elements that make up the architecture of an LTE network, for the project it is contemplated to simulate the fundamental elements that make up the LTE network which are: EPC (Evolved Packet Core), eNodeB (Evolved NodeB) and UE (User Equipment), and evaluate their performance; for this, the curricular integration work consists of three chapters structured as follows: Chapter 1 presents a brief summary of the evolution of mobile networks from the first generation to the current generation (5G), the network architecture and its main characteristics. The current situation of cellular networks in Ecuador is addressed. A description of the srsRAN platform, its characteristics and the distribution of the modules that compose it are made. Chapter 2 describes the architecture of the LTE network to be simulated, the installation processes of the srsRAN platform and the ZeroMQ library and its dependencies, the code and its configuration to implement the different parts of the LTE network are presented. and integrates them with the GNU Radio Companion tool. Chapter 3, the results obtained in the simulation of the LTE network are analyzed and synthetic traffic transmission tests are carried out, finally the conclusions and recommendations are presented.
