Abstract
The Aircraft IP Subnet System provides wireless communication services to passengers located onboard an aircraft by storing data indicative of individually identified wireless devices that are located onboard the aircraft. The Aircraft IP Subnet 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 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, so 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 allows this address to be directly visible to the ground-based communication network.
