Abstract

SE PRESENTA UN SISTEMA DE PAGINACION GLOBAL DE RADIO EN EL CUAL UNA PLURALIDAD DE PORTADORAS DE FRECUENCIA DE RADIO QUE TIENEN LA MISMA FRECUENCIA SE MODULAN DE FORMA SINCRONA EN UNA PLURALIDAD DE ESTACIONES BASE QUE SE CORRESPONDEN EN NUMERO CON LAS PORTADORAS DE FRECUENCIA DE RADIO CON LA MISMA SEÑAL DE PAGINACION DIGITAL Y SE TRANSMITEN, RESPECTIVAMENTE. UN CONTROLADOR DE PAGINACION QUE RECIBE LAS LLAMADAS DE PAGINACION A TRAVES DE UNA RED TELEFONICA PUBLICA CONMUTADA ALMACENA PRELIMINARMENTE EL VALOR MAXIMO DE UNA SUMA DE UN INTERVALO DE TRANSMISION DE UNA SEÑAL DE PETICION DE PAGINACION EN UNA LINEA DE TRANSMISION Y EL INTERVALO REQUERIDO PARA PROCESAR LA SEÑAL DE PETICION DE PAGINACION EN CADA UNA DE LAS ESTACIONES BASES Y SE PRODUCE UNA SEÑAL DE SINCRONIZACION DE ALTA PRECISION SOBRE LA BASE DE UNA SEÑAL DE REFERENCIA A PARTIR DE UN SATELITE GPS (SISTEMA DE POSICIONAMIENTO GLOBAL). EN ESTE CONTROLADOR DE PAGINACION, SE ACOPLA UN CODIGO DE ASIGNACION DE INTERVALO DE TRANSMISION A LA SEÑAL DE PETICION DE PAGINACION. EL CODIGO DE ASIGNACION DE TRANSMISION ASIGNA UN INTERVALO DE PRUEBA QUE SE RETARDA A PARTIR DE UN INTERVALO ACTUAL DETERMINADO POR LA SEÑAL DE SINCRONIZACION DE ALTA PRECISION MEDIANTE EL VALOR MAXIMO DE LA SUMA DEL INTERVALO DE TRANSMISION Y EL INTERVALO DE PROCESAMIENTO COMO UN INTERVALO DE INICIO DE TRANSMISION. POR OTRO LADO, EN CADA UNA DE LAS ESTACIONES BASE, SE PRODUCE UNA SEÑAL DE SINCRONIZACION DE ALTA PRECISION SOBRE LA BASE DE UNA SEÑAL DE SINCRONIZACION DE REFERENCIA A PARTIR DEL SATELITE GPS Y SE PROCESA LA SEÑAL DE PETICION DE PAGINACION SUMINISTRADA A TRAVES DE LA LINEA DE TRANSMISION SOBRE LA BASE DE LA SEÑAL DE SINCRONIZACION DE ALTA PRECISION PARA CONVERTIR UN FORMATO EN LA SEÑAL DE PAGINACION DIGITAL PARA DE ESTA FORMA REALIZAR UNA MODULACION SINCRONICA DE LAS PORTADORAS.
