Abstract

Una estacion movil (2) para ser utilizada en un sistema de comunicaciones que comprende una pluralidad de estaciones-base (4) controladas por uncontrolador de estaciones-base (6), comprende un receptor (50, 52, 54) para recibir senales procedentes deuna pluralidad de estaciones-base que conjuntamentecomprenden un conjunto de estaciones-base candidatas. La estacion movil determina la potencia en las senales recibidas, y compara la potencia con un primervalor umbral. La estacion movil (2) identifica las estaciones-base (4) cuyas senales tienen una potencia recibida mayor que el primer valor de umbral ytransmite una senal al controlador (6) representativa de estaciones-base identificadas como adecuadas para ser incluidas en un conjunto de losactivos. Laenergía medida de piloto, de cada uno de los pilotos del conjunto de los candidatos, es comparada de manera iterativa con un umbral generado de acuerdo con lasuma de la energía de los pilotos en el conjunto de los activos. Si el piloto más intenso (más fuerte) en el conjunto de los candidatos satisface estácondicion de umbral, es adicionado al conjunto de los activos, revisado. Se lleva a cabo un segundo proceso iterativo para determinar si un piloto ha de sersuprimido del conjunto de los activos, revisado. La estacion movil (2) determina si un cambio en el actual conjunto de los activos, es deseable, mediante lamedicion de las energías de los pilotos en el conjunto de los activos y en el conjunto de los candidatos, y ajustandodinámicamente los umbrales necesarios enbase a su propia estimacion del entorno de la comunicacion.
