Abstract
Un método y una disposicion para operar un sistema celular de comunicaciones en donde se maximiza la reutilizacionde frecuencias de lasfrecuencias portadoras disponibles, maximizando de este modo la capacidad de tráfico del sistema.La invencion incluye una rejilla de celdas exterioresgenerada por numerosos transceptores de estaciones de base conectados a un controlador de red comun. Dentro de la rejilla de celdas exteriores seencuentra por lo menos una sub-rejillasuperpue sta de celdas interiores que puede ser generada por las mismas estaciones de base que las celdas exteriores,o que puede ser generada usando transceptores de estaciones de base separados ubicados dentro de la celda exterior. Se aplicanpor lo me nos dos modelos dereutilizacion de frecuencias a las celdas, un modelo para las celdas exteriores y otro modelo más estrecho para las celdas interiores. Las celdas interioresson definidas y limitadas por un nivel de interferencia de canalcomun de umbral predeterminado (C/I), surgiendo la interferencia de las celdasinteirores adyacentes que operan a las mismas frecuencias. La invencion incluye también unidades moviles que pueden medir directamente tanto la RSSIcomo la C/I dela cel da servidora y de las celdas vecinas asociadas. Las unidades moviles realizan informes de mediciones periodicas que sontransmitidos a la red cunado se alcanza una condicion de interferencia de umbral predeterminada. Elcontrolador de la red conmuta entonces la unidadmovil a una de las celdas vecinas. El método y el sistema presentes pueden usarse con otras técnicas tradicionales para optimizar la reutilizacion defrecuencias, tal como métodos de calcesuperposicion o microcelula res.
