Method and system for mobile network nodes in heterogeneous networks

A system, comprising:

• a mobile network node that comprises:
• an interface management module that comprises hardware, the interface management module being operable to create a lookup table concerning available network interfaces between the mobile network node and at least one other mobile network node, and to update the lookup table;
• a signaling router module that comprises hardware, the signaling router module being operable to communicate configuration data based on the lookup table via an available signaling channel, and to create based on configuration data at least one signaling channel for transmission of configuration data via one of the available network interfaces;
• and
• a data router module that comprises hardware, the data router module being that is operable to create a data channel, by choosing one of the available network interfaces based on the configuration data via one of the available network interfaces, and to change the data channel from one available network interface to another available network interface, after determining based on the lookup table that quality of service of the one available network interface is insufficient.
