Abstract

LA INVENCION ACTUAL SE REFIERE A UN LOGICO DE TIEMPO QUE IMPLEMENTA LA SINCRONIZACION DE LOS TELEFONOS PORTATILES CON UNA RED GSM PARA MANTENER LA SINCRONIZACION EN TODOS LOS ESTADOS OPERATIVOS DE LOS TELEFONOS. EL LOGICO COMPRENDE UN CONTADOR DE NUMEROS DE ESTRUCTURA (1), QUE SE INCREMENTA MEDIANTE UN INTERRUPTOR DE ESTRUCTURA DERIVADO DEL CONTADOR DE LONGITUD DE ESTRUCTURA (2). EN EL CONTADOR DE LONGITUD DE ESTRUCTURA SE CARGAN LOS VALORES DESDE LOS REGISTROS (3, 4), QUE INDICAN SI LA LONGITUD DE LA ESTRUCTURA ES NORMAL O SE DESVIA. DESDE UN CONTADOR DE DIFERENCIA DE TIEMPO DE LAS ESTACIONES DE BASE PROXIMAS (6) SE OBTIENE EL MOMENTO CUANDO COMIENZA LA RECEPCION DE LA ESTRUCTURA DE SINCRONIZACION O LOS DATOS BCCH DE LAS ESTACIONES BASE PROXIMAS. LAS DIFERENCIAS DE LOS NUMEROS DE ESTRUCTURA Y LA BARRA DE TIEMPO DE ESTRUCTURA ENTRE LAS PROPIAS ESTACIONES BASE Y LAS ESTACIONES BASE PROXIMAS, SE ALMACENAN EN UN REGISTRO DE TIEMPO DE LAS ESTACIONES BASE PROXIMAS (9) DONDE DICHA DIFERENCIA DE TIEMPO SE CARGA A TRAVES DE UN REGISTRO DE DIFERENCIA DE TIEMPO (5) EN EL CONTADOR DE DIFERENCIA DE TIEMPO DE LAS ESTACIONES BASE PROXIMAS (6). UN CONTADOR DE TIEMPO DE AVANCE DE LA TRANSMISION (7) PROPORCIONA EL IMPULSO DE ARRANQUE. ESTE CONTADOR RECIBE EL VALOR DE AVANCE DESDE LOS REGISTROS DE TIEMPO DE LAS ESTACIONES BASE PROPIAS (10), EN LOS QUE SE DAN LOS VALORES DE AVANCE DE LAS TRANSMISIONES POR LA PROPIA ESTACION BASE, Y EN LOS QUE SE HA CARGADO EL VALOR DEL INTERVALO DE TIEMPO DE LA RECEPCION ABSOLUTA.
