Abstract

Sistemas y métodos para conmutar entre redes (por ejemplo, heterogéneas) y conexión entre redes entre un sistema de acceso de origen y un sistema de acceso de destino, al implementar la canalización desde la AT hasta el sistema de acceso de destino mediante el sistema de acceso de origen. Un componente de control de transferencia entre sistemas puede facilitar establecer la canalización por la unidad móvil hasta el sistema de acceso de destino y/o entre el sistema de acceso de origen y el sistema de acceso de destino - donde la señalización/formación de paquetes asociada con el sistema de destino puede transferirse sobre el sistema de origen.
