Análisis e Implementación en el LenguajeAbiertoPreprocesadorDeHipertexto(PHP)sobre Linux de una CentraldeConmutación(MSC)Virtual para la interacción a Nivel de Protocolo de Parte de Aplicaciones Móviles(MAP)con el RegistradordeUbicacióndeAbonado,(HLR)

Abstract

It is a simulation of signaling Mobile Applications Part (MAP) to demonstrate the change of location of a subscriber when changing coverage, explaining the procedure Handover. Further describe all parameters that are sent and received in each signaling message between the following components: Mobile Station (MS), Mobile Switching Center (MSC coverage Guayaquil), Mobile Switching Center (MSC Coverage Quito) and Location Register Subscriber (HLR). Programming the signaling held the Open Language Hypertext Preprocessor and for presenting, we will arm a network topology where intervene switch, router, laptops simulating the interaction of the components mentioned in the first paragraph. You can see the change in location of the mobile subscriber from Guayaquil to Quito and vice versa, and the parameters that the user possesses such information and step by step update messages signaling protocol MAP (Mobile Application Part).
