Abstract

PERIODICAMENTE, CUANDO EL MOVIL ESTA EN MODO DE FUNCIONAMIENTO NORMAL, UNA PRIMERA LISTA DE FRECUENCIAS DE BALIZA QUE SON EMITIDAS POR ESTACIONES DE BASE RESPECTIVAS QUE PERTENECEN A UNA ZONA GEOGRAFICA EN LA QUE SE INCLUYE EL MOVIL SE ALMACENA EN UNA TARJETA SIM (2), Y UNA SEGUNDA LISTA DE FRECUENCIAS DE BALIZA Y SEGUNDOS NIVELES DE RECEPCION ASOCIADOS RESPECTIVOS MAXIMOS MEDIDOS POR EL MOVIL SE ALMACENA EN UNA MEMORIA DE TIPO RAM (13). EN RESPUESTA A UNA PUESTA BAJO TENSION DEL MOVIL, ESTE ULTIMO MIDE UN PRIMER NIVEL DE RECEPCION PARA CADA UNA DE LAS FRECUENCIAS DE BALIZA DEFINIDAS EN LA RED, Y UN COMPARADOR (12) COMPARA EL PRIMER Y EL SEGUNDO NIVEL DE RECEPCION PARA CADA UNA DE LAS FRECUENCIAS DE BALIZA DE LA SEGUNDA LISTA, PARA EVALUAR UN DESPLAZAMIENTO DEL MOVIL (1). EL MOVIL UTILIZA, PARA SINCRONIZAR SOBRE UNA RED DE ABONADO DADA, QUE CONSTITUYE UNA SUBRED DE LA RED DE RADIOCOMUNICACION, LAS FRECUENCIAS DE BALIZA DEFINIDAS EN DICHA RED DE RADIOCOMUNICACIONES, Y LAS FRECUENCIAS DE BALIZA DE LA PRIMERA LISTA, RESPECTIVAMENTE SEGUN QUE EL MOVIL HAYA SIDO DESPLAZADO Y NO HAYA SIDO DESPLAZADO.
