Abstract

Las formas de realización dan a conocer técnicas para la asignación dinámica de haz puntual en una red de comunicaciones por satélite geoestacionario. A modo de ejemplo, un nodo de procesamiento terrestre en la red de satélites geoestacionarios puede supervisar la ubicación de la zona de cobertura de haz puntual y puede detectar un iniciador de deriva de haz que indica una deriva actual de una o más zonas de cobertura. Los terminales terrestres pueden identificarse como atendidos por haces puntuales asociados con la zona o zonas de cobertura de deriva y experimentar un impacto en la calidad de la señal como consecuencia de la deriva. El nodo de terminal terrestre puede calcular una actualización de un mapa de asignación de haz que tiene una reasignación de los terminales de usuario identificados desde sus haces puntuales actualmente en servicio a otro de los haces puntuales de una manera que busca abordar al menos parte del impacto en la calidad de la señal identificada como asociada con la deriva. Algunas formas de realización explican, además, el equilibrio de carga y/o los otros factores, y/o pueden mantener comunicaciones de estado entre los terminales de usuario reasignados y el satélite geoestacionario.
