Abstract

La presente invención se refiere a método para la detección de errores en sistemas de telefonía celular, caracterizado porque incluye las etapas de detectar una cantidad de bitios en un primer y un segundo conjunto de bitios comparado con un patrón de bitios válido y silenciar un radioteléfono en respuesta a la cantidad de errores de bitios detectada en el primer y segundo conjunto de bitios, si las cantidades exceden un primer y un segundo umbral predeterminados, respectivamente, a menos que uno de los primeros y segundos conjuntos de bitios tenga una cantidad de errores menor que un tercer umbral cuando se compara con un patrón de bitios alternativo y válido.
