Abstract

A communications system that provides broadband access to passengers of mobile platforms includes a router located on the mobile platform. A network is connected to the router. User communication devices (UCDs) connected to the network, wherein the UCDs establish point-to-point over Ethernet (PPPoE) sessions with the router. A transmitter and a receiver are connected to the router. A satellite and a ground station are in communication with the transmitter and the receiver. A distributed communications system includes virtual private networks (VPN) and is connected to the ground station. A first address manager leases the use of public IP addresses by the mobile platform. A second address manager assigns the public IP addresses to UCDs when the UCDs request access to the VPNs and private IP addresses for other network service. The UCDs employ IPSec protocol when accessing the VPNs.

Claims

1. A communications system for providing broadband access to passengers of mobile platforms, comprising:

a router located on said mobile platform;

a network connected to said router;

user communication devices (UCDs) connected to said network, said UCDs establishing point-to-point over Ethernet (PPPoE) sessions with said router;

a transmitter on said mobile platform, said transmitter being connected to said router;

a receiver on said mobile platform, said receiver being connected to said router;

a satellite in communication with said transmitter and said receiver of said mobile platform;

a ground station in communication with said satellite;

a distributed communications system connected to said ground station;

a virtual private network (VPN) connected to said distributed communications system;

a first address manager connected to said ground station, said first address manager leasing use of public Internet Protocol (IP) addresses by said mobile platform;

said router including a second address manager communicating with said first address manager to lease said public IP addresses for said mobile platform.

2. The communications system of claim 1 wherein said distributed communications system is the Internet.

3. The communications system of claim 1, said second address manager assigning said public IP addresses when said UCDs request access to said VPN.

4. The communications system of claim 3, said second address manager assigning private IP addresses to said UCDs for at least one network service provided by said mobile platform.

5. The communications system of claim 1, said UCDs employing IPSec security protocol when communicating with said VPN.

6. A communications system for allowing passengers of mobile platforms to access virtual private networks (VPNs), comprising:

a network on said mobile platform communicating with a ground station via a satellite, said ground station being connected to a virtual private network (VPN);

user communication devices (UCDs) connected to said network; and

a first address manager connected to said network, said first address manager being operable to enable public internet protocol (IP) addresses to be assigned when said UCDs request a connection to said VPN, said first address manager enabling assigning private IP addresses for at least one other network service, said first address manager assigning said public and private addresses without requiring said UCDs to reboot.

7. The communications system of claim 6 further comprising:

a router connected to said UCDs and to enable said first address manager, said UCDs establishing point-to-point over Ethernet (PPPoE) sessions with said router.

8. The communications system of claim 6 further comprising:

a second address manager, connected to said ground station and a distributed communications system, for enabling a leasing of use of said public IP addresses to said mobile platform.

9. A public address manager for a broadband communications system for mobile platforms, comprising:

a network on said mobile platform that communicates with a ground station via a satellite;

user communication devices (UCDs) connected to said network;

a first address manager associated with said mobile platform that requests a public address block for said mobile platform; and

a second public address manager associated with said ground station that leases said public address block to said first address manager.

10. The public address manager of claim 9, said first address manager enabling periodic transmission of a lease maintenance message to said second address manager.

11. The public address manager of claim 10, said second address manager including a lease timer, enabling termination of said lease if said lease timer expires before said lease maintenance message is received.

12. A method for operating a communications system that provides broadband access to passengers of mobile platforms, comprising:

locating a router on said mobile platform;

connecting a network to said router;

connecting user communication devices (UCDs) to said network;

establishing point-to-point over Ethernet (PPPoE) sessions between said UCDs and said router;

connecting a transmitter to said router;

connecting a receiver to said router;

communicating with a satellite and a ground station that is connected to a distributed communications system using said transmitter and said receiver of said mobile platform, said distributed communications system connecting to a virtual private network (VPN);

managing use of public address blocks using a first address manager; and

requesting said public address blocks using a second address manager associated with said mobile platform.

13. The method of claim 12 wherein said distributed communications system is the Internet.

14. The method of claim 12 further comprising:

assigning public IP addresses to said UCDs when said UCDs request access to said VPN.

15. The method of claim 14 further comprising:

assigning private IP addresses to said UCDs for a network service.

16. The method of claim 12 wherein said UCD employs IPSec security protocol when communicating with said VPN.

17. A method for allowing passengers of mobile platforms to access virtual private networks (VPNs), comprising:

providing a network on said mobile platform;

connecting user communication devices (UCDs) to said network;

providing a first address manager on said network that assigns public internet protocol (IP) addresses to said UCDs when said UCDs request access to said VPNs; and

using said first address manager to assign private IP addresses for a service provided by said network, said public and private addresses being assigned without requiring said UCDs to reboot.

18. The method of claim 17 further comprising:

connecting a router to said UCDs and to said first address manager; and

establishing point-to-point over Ethernet (PPPoE) sessions between said UCDs and said router.

19. The method of claim 18 further comprising:

connecting a second address manager (PAM) to a ground station; and

leasing use of said public IP addresses to said first address manager using said second address manager.

20. A communications system for providing broadband access to passengers of mobile platforms, comprising:

a router located on said mobile platform;

a network connected to said router;

user communication devices (UCDs) connected to said network;

a ground station in communication with said mobile platform; and

a first address manager connected to said ground station that leases use of public Internet Protocol (IP) addresses by said mobile platform, said router including a second address manager enabling communication with said first address manager to lease public IP addresses for said mobile platform.

21. The communications system of claim 20, wherein said UCDs are connected to said router by point-to-point over Ethernet (PPPoE) sessions.
