Abstract

A dual-mode terminal designed to connect to an IP-based network via a first communication system and a second communication system, the dual-mode terminal including a first physical network interface module adapted to establish a packet-based communication with the IP-based network via the first communication system, the first physical network interface module being accessible via a first physical network interface having a first physical network address; a second physical network interface module adapted to establish a packet-based communication with the IP-based network via the second communication system, the second physical network interface module being accessible via a second physical network interface having a second physical network address; an IP-based protocol stack adapted to operate between a software application in the dual-mode terminal and the first and second physical network interface modules; and a system for performing a seamless handover between the first communication system and the second communication system during a connection to the IP-based network.
