METHOD AND SYSTEM FOR MOBILE IP NODES IN HETEROGENEOUS NETWORKS

摘要

This invention relates to a method for mobile IP (10) in heterogeneous networks (21-24) in which an interface administration module (134) of the mobile node (10) checks the mobile node (10) for available physical network interfaces (14-17), draws up a lookup table with the available and configurable physical network interfaces (14-17), and links itself to one of the available physical network interfaces (14-17). IP applications (11) of the mobile nodes (10) access the heterogeneous networks via a virtual IP network interface (133) generated in the mobile node (10), the permanent virtual IP network interface (133) being connected to the present network (21-24) via the interface administration module (134). During the change of physical network interfaces (14-17) of the mobile node (10), the linking of the permanent virtual IP network interface to the network (21-24) is updated by means of the interface administration module (134) based on the lookup table. In particular, the invention relates to a method for mobile nodes (10) with real-time applications in heterogeneous networks (21-24).
