Abstract
Se describe un metodo y aparato para rastrear el largo de un periodo de reposo en una estacion movil que utiliza un reloj de reposo para calibrar con precision porciones del periodo de reposo. El periodo de reposo se subdivide en una secuencia de sub-periodos cada uno de duracion conocida en el que las duraciones de los sub-periodos no son necesariamente multiplos enteros de los ciclos del reloj de reposo. El tiempo transcurrido se rastrea en cada sub-periodo individual del periodo de reposo utilizando un contador de reposo da enteros el cual rastrea todos los ciclos del reloj de reposo. Despues se rastrea cualquier porcion fraccional restante de los ciclos del reloj de modo de reposo no contabilizada por el contador de reposo de enteros utilizando un contador de reposo fraccional. El contador de reposo fraccional acumula las porciones fraccionales restantes de ciclos de modo de reposo de un sub-periodo al siguiente. Se describen tambien un metodo y aparato para calcular la variacion de frecuencia con una senal de reloj de reposo utilizada durante un modo de operacion de llamada ranurada de una estacion movil inalambrica. Se determina una frecuencia inicial de la senal de reloj de reposo despues del encendido de la estacion movil. Despues se determina un factor de compensacion de variacion de frecuencia fija representativo de una diferencia entre la frecuencia inicial de la senal de reloj de reposo y una frecuencia nominal pre-determinada. Se calcula un factor de compensacion de error de frecuencia dinamica representativo de una diferencia entre la frecuencia inicial y una frecuencia actual de la serial de reloj lento. Despues, mediante el modo de operacion ranurado, se determinan iterativamente valores nuevos para el factor de compensacion de frecuencia dinamica utilizando un filtro de lazo.
