Abstract

Un método y sistema mejorado para llevar a cabo una operacion de busqueda de señal piloto previa a la transferencia en la estacion movil (18) de la comunicacion entre las estaciones base (12, 14). La estacion movil (18) mantiene una lista de señales piloto del Conjunto Activo transmitidas a partir de estaciones base a través de las cuales se comunica la estacion movil, y una lista de señales piloto del Conjunto Vecino (N) provenientes de las estaciones base dentro de una proximidad predeterminada de la estacion movil (18). La operacion de busqueda contempla la comparacion de las mediciones de resistencia de señal piloto correspondientes a cada entrada de estacion base dentro del Conjunto Vecino (N) con un primer nivel predeterminado. Una o más entradas provenientes del Conjunto Vecino (N) que tienen una medicion de resistencia de señal de estacion base mayor al primer nivel predeterminado pueden colocarse en el Conjunto Pre-Candidato (PC). Las resistencias de las señales piloto asociadas con entradas en el Conjunto Pre-Candidato (PC) se evaluan después de manera adicional para predeterminar la elegibilidad dentro del Conjunto Candidato (C), del cual se seleccionan las entradas que comprenden el Conjunto Activo.
