Abstract
Se describen un método y sistema para realizar traspasos del servicio en los sistemas de radiocomunicaciones usando un valor de histéresis variable en eltiempo. Variando el valor de histéresis de acuerdo con una cantidad de tiempo que la estacion movil ha estado usando un canal actual, se pueden evitar losproblemas asociados con la medicion de las potencias de senal atribuibles a la inicializacion del filtro.
