Abstract

Systems and methods for roaming between a mobile node and at least one serving node connected to a network are disclosed. The present application provides a method for roaming between. In the system and method, a first communication is established between the mobile node and one of the serving nodes through a control server, when an Ethernet transceiver is used by the mobile node. Ethernet is used for communications between the mobile node and the control server, and a wireless communication technology for communications between the control server and the serving node. The control server also translates communications between Ethernet and the wireless communication technology. In the system and method, a second communication is established between the mobile node and one of the serving nodes with the wireless communication technology, when a wireless communication technology transceiver is used by the mobile node.

Claims (31)

1. A control server comprising:

a first network interface operable to transmit and receive Point-to-Point over Ethernet (PPPoE) signaling messages to and from a first device;

a second network interface operable to transmit and receive radio access network to packet data serving node (R-P) signaling messages to and from a second device;

a first logic unit for translating said received PPPoE signaling messages to R-P signaling messages for transmission to the second device;

a second logic unit for translating said received R-P signaling messages to PPPoE signaling messages for transmission to the first device.

2. The control server according to claim 1 , wherein said first logic unit and said second logic unit are operable to establish a Point-to-Point (PPP) session having said first device as a first end point of said PPP session and having said second device as a second end point of said PPP session.

3. The control server according to claim 1 , wherein said first logic unit and said second logic unit are implemented in a single logic unit.

4. The control server according to claim 1 , wherein said first logic unit includes both hardware and software.

5. The control server according to claim 1 , wherein said first logic unit includes only hardware.

6. The control server according to claim 1 , wherein said first logic unit includes only software.

7. The control server according to claim 1 , wherein said second logic unit includes both hardware and software.

8. The control server according to claim 1 , wherein said second logic unit includes only hardware.

9. The control server according to claim 1 , wherein said second logic unit includes only software.

10. The control server according to claim 1 , wherein said first logic unit is operable to translate a PPPoE Active Discovery Request (PADR) PPPoE signaling message to a R-P Registration Request message.

11. The control server according to claim 1 , wherein said second logic unit is operable to translate a R-P Registration Reply to a PPPoE Active Discovery Session-confirmation (PADS) message.

12. The control server according to claim 1 , wherein said second logic unit is operable to translate a R-P Registration Reply to a PPPoE Active Discovery Terminate (PADT) message.

13. The control server according to claim 1 , wherein said first logic unit is operable to translate a PADT message to a R-P Registration Request message having a lifetime field equal to zero.

14. The control server according to claim 1 , wherein said first and second logic units are operable to tear down a PPP session having said first device as a first end point of said PPP session and said second device as a second end point of said PPP session.

15. A control server comprising:

a first network interface operable to send and receive Point-to-Point Protocol over Ethernet (PPPoE) signaling messages to and from a first device;

a second network interface operable to send and receive General Packet Radio Service (GPRS) tunneling protocol (GTP) signaling messages to and from a second device;

a first logic unit for translating said received PPPoE signaling messages to GTP signaling messages to the second device;

a second logic unit for translating said received GTP signaling messages to PPPoE signaling messages for transmission to the first device.

16. The control server according to claim 15 , wherein said first and second logic units are operable to establish a Point-to-Point Protocol (PPP) session having said first device as a first end point of the PPP session and said second device as a second end point of the PPP session.

17. The control server according to claim 15 , wherein said first logic unit and said second logic unit are implemented in a single logic unit.

18. The control server according to claim 15 , wherein said first logic unit includes both hardware and software.

19. The control server according to claim 15 , wherein said first logic unit includes only hardware.

20. The control server according to claim 15 , wherein said first logic unit includes only software.

21. The control server according to claim 15 , wherein said second logic unit includes both hardware and software.

22. The control server according to claim 15 , wherein said second logic unit includes only hardware.

23. The control server according to claim 15 , wherein said second logic unit includes only software.
