Abstract

Un procedimiento para proporcionar una estimación del tiempo absoluto en base a una información de tiempo procedente de una pluralidad de sistemas de comunicación, que comprende: obtener el tiempo absoluto a partir de un primer sistema de comunicación para un primer instante de tiempo; recibir un primer mensaje de señalización a partir de un segundo sistema de comunicación en un segundo instante de tiempo; determinar un desplazamiento de tiempo entre los instantes de tiempo primero y segundo; recibir un segundo mensaje de señalización a partir del segundo sistema de comunicación en un tercer instante de tiempo; determinar un tiempo transcurrido entre los instantes de tiempo segundo y tercero; determinar una diferencia de tiempo entre el tercer instante de tiempo y un cuarto instante de tiempo; y proporcionar una estimación del tiempo absoluto en el cuarto instante de tiempo en base al tiempo absoluto para el primer instante de tiempo, el desplazamiento de tiempo, el tiempo transcurrido y la diferencia de tiempo.
