Análisis e Implementación de un Servidor de Protocolo de Mensajería Escrita Punto a Punto (SMPP) versión 3.4 en Linux que interactúe con un Cliente SMPP en el envío y recepción de mensajes cortos (SMS’s) y que genere archivos de registros de datos de llamadas, CDRs

Abstract

The present project is directed to any student and professor in the field of Telecommunications Engineering who wishes to learn the SMPP v3.4 protocol in a didactics manner, detailing the principal processes, its functionality, and showing punctual results. The SMPP v3.4 protocol is detailed from a server’s point of view, it is to say a limited implementation from centralized services of short messages (SMSC). To perform tests, it is interacted with an external entity (ESME). This implementation takes place in a virtual machine VMware through programming language: The Practical Extraction and Report Language (PERL) for the implementation of SMPP protocol and dynamic language for Personal Home Pages (PHP) for the Web application. The database used is MariaDB. An analysis of the messages sent between ESME and SMSC is detailed, observing the results of all the limited SMSC implementation through the Wireshark tool.
