Abstract

LA INVENCION SE REFIERE A UN METODO EN CONEXION CON "MANOS LIBRES" DESDE UNA PRIMERA ESTACION BASE (1) EN UN SISTEMA DE COMUNICACION MOVIL DE RADIO, EN CUYO METODO LA FUERZA DE LA SEÑAL DESDE UN JUEGO DE ESTACION BASE (1) RODEANDO UNA ESTACION MOVIL ES MEDIDA EN ESTA ULTIMA. CUANDO SE CONSIDERA NECESARIA LA OPERACION DE "MANOS LIBRES", EL VECTOR DE FUERZA DE SEÑAL FORMADO POR LAS FUERZAS DE SEÑAL MEDIDAS ES RELACIONADO CON VECTORES DE FUERZA DE SEÑALES CARACTERISTICAS ALMACENADOS ASOCIADOS CON LA PRIMERA ESTACION BASE (1). SI LA RELACION ENTRE EL VECTOR DE FUERZA DE SEÑAL MEDIDO Y UNO DE ESTOS DICHOS VECTORES DE FUERZA DE SEÑAL CARACTERISTICA ALMACENADA, EXCEDA. UN NIVEL DE RELACION PREDETERMINADO, LAS "MANOS LIBRES" ES DIRIGIDO A UNA SEGUNDA ESTACION BASE PREDETERMINADA (2-7) EN EL JUEGO QUE TIENE ACEPTACION, PERO NO LA MAYOR FUERZA DE SEÑAL EN EL VECTOR DE FUERZA DE SEÑAL MEDIDA, O SE INTERRUMPE EL PROCEDIMIENTO DE "MANOS LIBRES" Y SE MANTIENE LA CONEXION ENTRE LA ESTACION MOVIL Y LA PRIMERA ESTACION BASE.
