“ANÁLISIS E IMPLEMENTACIÓN DE UN DISPOSITIVO VIRTUAL EN EL LENGUAJE ABIERTO PREPROCESADOR DE HIPERTEXTO (PHP) SOBRE LINUX QUE EMULE UN DISPOSITIVO MÓVIL PARA LA GENERACIÓN DE LLAMADAS PREPAGO, POSTPAGO Y EL ENVIÓ Y RECEPCIÓN DE MENSAJES CORTOS (SMS), CON UNA INTERACCIÓN DIRECTA CON UNA CENTRAL DE CONMUTACIÓN MÓVIL (MSC).”

Abstract

The project is based on the architecture of the SS7 protocol, which implement different process like prepaid and postpaid calling from a virtual device in the open language Hypertext Preprocessor (PHP) that will simulate a mobile station (MS) on the system LINUX operation that have a direct interaction with a Mobile Switching Center (MSC) .The viewer of the mobiles stations and the flow of signaling between entities are executed by multiple files in PHP and HTML format to create scripts to generate a virtual platform that simulate the flow of messages between a mobile station and a switching center, also it makes basics services of mobile telephony like calls, location update, consultation and buying credit . The principal target for it get this virtual platform is describe the steps required to install and adjust, on a Linux server packages needed to develop the implementation of the SS7 protocol prepaid call from the mobile station to the MSC, and other processes. As a result we obtained a didactic application in which we apply SS7 signaling protocol and in which make different process of mobile telephony.
