Abstract

A method and apparatus for transparently providing a remote node with mobile network functionality. One embodiment of the present invention includes a remote node contacting a service provider to establish a remote connection with a home network. In response, the service provider generated an authentication request, on behalf of the remote node to obtain access to the home network. The service provider then sends the authentication request to an authentication server residing at the home network. The service provider then establishes, on behalf of the remote node, a remote connection between the remote node and the home network to enable packets to be transferred between the remote node and the home network.

Claims

1. A method to allow a remote node, exclusive of software capable of independently providing mobile network functionality, to establish data communication with a home network, the method comprising:

a remote access server (RAS) detecting an attempt by the remote node to establish communication with the home network;

the RAS authenticating the remote node through an authentication server (AS) associated with the home network, said authenticating performed transparently relative to the remote node; and

the RAS initiating a tunnel connection with a gateway (GW), on behalf of the remote node, that provides access to the home network, wherein the tunnel connection enables packets associated with a first protocol to be transmitted between the remote node and the home network according to a second protocol, to establish data communication between the remote node and the home network.

2. The method of claim 1, further comprising:

the RAS generating an authentication request, on behalf of the remote node, to obtain access to the home network;

the RAS sending the authentication request to an authentication server (AS) residing at the home network.

3. The method of claim 2, further comprising:

the RAS providing a point-of-presence for accessing a service provider, wherein the service provider is associated with the gateway (GW) providing a connection to the home network; and

the RAS including a tunnel management system (TMS).

4. The method of claim 1, further comprising:

the RAS receiving a connection from the remote node, wherein the connection is generated by the remote node dialing into the RAS.

5. The method of claim 3, further comprising:

the RAS providing the TMS with a domain name provided by the remote node; and

the RAS requesting the TMS to provide the RAS with at least an address of the gateway providing the connection with the home network, an address of the authentication server residing in the home network, and an authentication protocol used by the authentication server residing in the home network.

6. The method of claim 2, further comprising:

the RAS sending the authentication request to the GW, wherein the authentication request includes at least the address of the authentication server residing in the home network.

7. The method of claim 1, further comprising:

the RAS receiving a response from the GW completing the tunnel connection with the RAS.

8. The method of claim 1 implemented on a switching system product.

9. The method of claim 1 implemented on a transmissions system product.

10. A computer-readable medium having stored thereon a plurality of instructions including a first set of instructions for providing a remote node with a mobile network connection, wherein the first set of instructions, when executed by a processor, cause the processor to perform a method comprising:

a remote access server (RAS) detecting an attempt by the remote node, exclusive of software capable of independently providing mobile network functionality, to establish communication with a home network;

the RAS authenticating the remote node through an authentication server (AS) associated with the home network, said authenticating performed transparently relative to the remote node; and

the RAS initiating a tunnel connection with a gateway (GW), on behalf of the remote node, that provides access to the home network, wherein the tunnel connection enables packets associated with a first protocol to be transmitted between the remote node and the home network according to a second protocol, to establish communication between the remote node and the home network.

11. The computer-readable medium of claim 10, wherein the method further comprises:

the RAS generating an authentication request, on behalf of the remote node, to obtain access to the home network; and

the RAS sending the authentication request to an authentication server (AS) residing at the home network.

12. The computer-readable medium of claim 11, wherein the method further comprises:

the RAS providing a point-of-presence for accessing a service provider, wherein the service provider is associated with the gateway (GW) providing a connection to the home network; and

the RAS including a tunnel management system (TMS).

13. The computer-readable medium of claim 10, wherein the method further comprises:

the RAS receiving a connection from the remote node, wherein the connection is generated by the remote node dialing into the RAS.

14. The computer-readable medium of claim 12, wherein the method further comprises:

the RAS providing the TMS with a domain name provided by the remote node; and

the RAS requesting the TMS to provide the RAS with at least an address of the gateway providing the connection with the home network, an address of the authentication server residing in the home network, and an authentication protocol used by the authentication server residing in the home network.

15. The computer-readable medium of claim 11, wherein the method further comprises:

the RAS sending the authentication request to the GW, wherein the authentication request includes at least the address of the authentication server residing in the home network.

16. The computer-readable medium of claim 10, wherein the method further comprises:

the RAS receiving a response from the GW completing the tunnel connection with the RAS.

17. The computer-readable medium of claim 10 implemented on a switching system product.

18. The computer-readable medium of claim 10 implemented on a transmissions system product.

19. An apparatus comprising:

a remote access server (RAS) to detect an attempt by a remote node, exclusive of software capable of independently providing mobile network functionality, to establish communication with a home network;

the RAS to authenticate the remote node through an authentication server (AS) associated with the home network, said authenticating performed transparently relative to the remote node; and

the RAS to initiate a tunnel connection with a gateway (GW), on behalf of the remote node, that provides access to the home network, wherein the tunnel connection enables packets associated with a first protocol to be transmitted between the remote node and the home network according to a second protocol, to establish communication between the remote node and the home network.

20. The apparatus of claim 19, wherein:

the RAS is operable to generate an authentication request, on behalf of the remote node, to obtain access to the home network, and to provide the authentication request to an authentication server (AS) residing at the home network.

21. The apparatus of claim 19, wherein:

the RAS is further operable to provide a point-of-presence to access a service provider, wherein the service provider is associated with the gateway (GW) that provides access to the home network; and

wherein the RAS includes a tunnel management system (TMS).

22. The apparatus of claim 19, wherein:

the RAS detects the attempt by a remote node to establish communication with a home network in response to the remote node dialing into the RAS.

23. The apparatus of claim 21, wherein:

the RAS is operable to provide the TMS with a domain name provided by the remote node, and further operable to request the TMS to provide the RAS with at least an address of the gateway that provides access to the home network, an address of the authentication server that resides in the home network, and an authentication protocol used by the authentication server that resides in the home network.

24. The apparatus of claim 20, wherein:

the RAS is operable to send the authentication request to the GW, wherein the authentication request includes at least the address of the authentication server that in the home network.

25. The apparatus of claim 19, wherein the apparatus comprises a switching system product.
