Method and system for mobile IP-nodes in heterogeneous networks

A system for automatic optimization of communication links or communication networks between a first and a second mobile network node, the first mobile network node comprising an interface administration module, wherein

• the first mobile network node is configured to check by a first checking unit of the interface administration module for different types of network interfaces that are simultaneously available, and is configured to update a first look-up table with the available network interface obtained by the interface administration module, the first look-up table located in a storage unit at the first mobile network node,
• the first mobile network node comprises a signaling router module, the signaling router module configured to choose a signaling channel, from the first mobile network node to the second mobile network node, by selecting one of the available network interfaces resulting from the first look-up table updated by the checking made by the first checking unit, and transmitting first configuration data including data throughput information on the available network interfaces to the second mobile node via the chosen one of the available network interfaces,
• the second mobile network node is configured to check by a second checking unit of the interface administration module for available network interfaces that are simultaneously available, and is configured to update a second look-up table with the available network interface obtained by the interface administration module, the second look-up table located in a storage unit at the first mobile network node,
• the second mobile network node is configured to transmit second configuration data including data throughput information for the available network interfaces based on information of the second look-up table from the second mobile network node to the first mobile network node, and
• the data router module of the first mobile network node is configured to establish the data channel based on the first look-up table, the second look-up table, and the first and second configuration data to choose an available network interface with the highest data throughput.
