SYSTEM FOR CREATING AIR-TO-GROUND IP TUNNEL IN AIRBORNE WIRELESS CELLULAR NETWORK TO DIFFERENTIATE INDIVIDUAL PASSENGERS Russian patent published in 2014 - IPC H04W84/06 H04W80/06 H04L29/06 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to wireless communication and specifically to a system which creates an air-to-ground IP tunnel in an airborne wireless cellular network. The technical result is controlling a broadband connection to enable individual passenger identification by assigning unique individual IP addresses to each passenger wireless communication device in existing wireless networks. Said technical result is achieved due to that the aircraft air-to-ground IP tunnel system assigns a single IP address to each point-to-point protocol link connecting the aircraft network to the ground-based communication network and creates an IP subnet onboard the aircraft. The IP subnet uses a plurality of IP addresses for each point-to-point link, enabling each passenger wireless device to be uniquely identified with its own IP address. This is enabled since both point-to-point protocol IPCP endpoints have pre-defined IP address pools and/or topology configured, so that each point-to-point protocol endpoint can use a greater number of IP addresses than one per link.

EFFECT: such an approach does not change IPCP or other protocols/messaging but allows a given address to be directly visible to the ground-based communication network.
