SYSTEM FOR MANAGING MOBILE INTERNET PROTOCOL ADDRESSES IN AN AIRBORNE WIRELESS CELLULAR NETWORK
First Claim
1. An Aircraft Mobile IP Address System for providing individual ground-based IP addresses to a plurality of passenger wireless devices which are located onboard an aircraft, comprising:
- aircraft network means, located in said aircraft, for generating radio frequency communication signals to communicate with at least one of said plurality of passenger wireless devices located in said aircraft;
ground-based Access Network means for exchanging communication signals with at least one ground-based communication network; and
Air-To-Ground network means for radio frequency communications between said aircraft network means and said ground-based Access Network means for transmitting data packets, independent of the multiple IP addresses associated with the multitude of passenger wireless devices on the aircraft, between said aircraft network means and said ground-based Access Network means.

Abstract
The Aircraft Mobile IP Address System provides wireless communication services to passengers who are located onboard an aircraft by storing data indicative of the individually identified wireless devices located onboard the aircraft. The System assigns a single IP address to each Point-to-Point Protocol link which connects the aircraft network to the ground-based communication network but also creates an IP subnet onboard the aircraft. The IP subnet utilizes a plurality of IP addresses for each Point-to-Point link thereby to enable each passenger wireless device to be uniquely identified with their own IP address. This is enabled since both Point-to-Point Protocol IPCP endpoints have pre-defined IP address pools and/or topology configured; each Point-to-Point Protocol endpoint can utilize a greater number of IP addresses than one per link. Such an approach does not change IPCP or other EVDO protocols/messaging but does allow this address to be directly visible to the ground-based communication network.
