Abstract

Un método para evitar una pérdida de comunicacion con una estacion movil en una disposicion de comunicaciones inalámbricas, particularmente para llevara cabo un handoff duro inter-sistemas entre sistemas de comunicaciones o un handoff duro inter-frecuencias dentro de un sistema de comunicaciones CDMA. Elmétodo propone reducir la probabilidad de llamadas caídas durante el handoff inter-sistemas. En el caso en que una tentativa de handoff no es exitosa, laestacion movil volverá al sistema original con informacion que el sistema de comunicaciones de la presente invencion utiliza para ayudar en laperformance de futuras tentativas de handoff. Como alternativa, sin que haga una tentativa de handoff, la estacion movil supervisael sistema de destino yseguidamente vuelve al sistema original con informacion que se utiliza para ayudar en subsiguientes tentativas de handoff. La informacion devueltaprocedente de la supervision de un sistema CDMA, consiste en resultados de una exploracion o busqueda de uno o más pilotos dados de a desplazamientos en unalista específica provista a la estacion movil por la estacion de base o un conjunto de desplazamientos basados en un predeterminado algoritmo deexploracion.
