Abstract

La invención se refiere a un método y sistema mejorados para llevar a cabo una operación de senal piloto en anticipación de entrega en comunicación deestación móvil entre estaciones de base y a un aparato explorador para llevar a cabo dicho método.La operación de exploración se describe aquí como siendoimplementada dentro de un sistema de comunicación celular que utiliza técnicas de modulación de acceso múltiple de división de código (CDMA). La estaciónmóvil mantiene una lista de un ConjuntoActivo de senales piloto transmitidas de estaciones de base con las cuales la estación móvil se comunica, y unConjunto Vecinal de pilotos de estaciones de base dentro de una proximidad predeterminada de la estación móvil. Además de los Conjuntos Activos yVecinales de pilotos, la estación móvil mantiene una lista de Conjuntos de pilotos de Candidatos y Pre-Candidatos. Basado en el análisis de la potencia desenal de las senales piloto recibidas en la estación móvil, las entradas deestación de base del Conjunto Vecinal se puede asignar a los Conjuntos deCandidatos y Pre-Candidatos, y eventualmente al conjunto Activo.
