Abstract

A method and apparatus for allowing a plurality of mobile nodes to access a network with one or more Network Access Identifiers (NAIs), This allows a user to access a network with multiple mobile nodes using a single NAI. The method and apparatus is achieved by the addition of a Session/Device Extension, a Host Identification Extension, a Host Identification NAI Extension, and/or a Lease Time Extension.

Claims

1. A method for communicating with a user having a plurality of mobile nodes in an IP-based network, the method comprising the steps of:

receiving a registration request message from each of at least two of the plurality of mobile nodes, each of the registration request messages comprising a single Network Access Identifier, NAI, wherein the single NAI identifies the user to the IP-based network;

creating and maintaining a list of active mobile nodes associated with the single NAI;

selecting two or more mobile nodes from the list of active mobile nodes to which the one or more communications are to be sent, wherein the two or more mobile nodes are selected based upon at least one of active times, active days, a device identifier, an IP address, a device priority, a list of blocked NAIs, and a list of allowed NAIs; and

simultaneously sending one or more communications to two or more mobile nodes contained on the list of active mobile nodes.

2. The method of claim 1, wherein the step of receiving a registration request message further comprises the step of receiving a Session/Device Identification Extension uniquely identifying at least one of the one or more mobile nodes.

3. The method of claim 1, wherein the step of receiving a registration request message further comprises the step of receiving an indication of a host for at least one of the one or more mobile nodes.

4. The method of claim 1, wherein the step of receiving a registration request message further comprises the step of receiving an indication of a host for at least one of the one or more mobile nodes, the indication being a host identification extension comprising a host identifier.

5. The method of claim 1, wherein the step of receiving a registration request message further comprises the step of receiving an indication of a host for at least one of the one or more mobile nodes, the indication being a host identification extension comprising a host identifier NAI.

6. The method of claim 1, wherein the step of receiving a registration request message further comprises the step of receiving an indication of the length of time at least one of the one or more mobile nodes are authorized for use.

7. The method of claim 1, wherein the list of active mobile nodes comprises at least one of a device identifier, active times, active days, a device priority, a list of blocked NAIs, a list of allowed NAIs, and an IP address.

8. The method of claim 1, wherein the plurality of mobile nodes further comprises at least one fixed node.

9. The method of claim 1 further comprising, implementing a unified billing system, wherein a user is jointly billed for at least two of the plurality of mobile nodes.

10. The method of claim 1 further comprising, enabling a user to update characteristics for at least one mobile node through an IP-based network interface.

11. An apparatus for communicating with a user having a plurality of mobile nodes in an IP-based network, the apparatus comprising:

means for receiving a registration request message from each of at least two of the plurality of mobile nodes, each of the registration request messages comprising a single Network Access Identifier, NAI, wherein the single NAI identifies the user to the IP-based network;

means for creating and maintaining a list of active mobile nodes associated with the single NAI;

means for selecting two or more mobile nodes from the list of active mobile nodes to which the one or more communications are to be sent, wherein the two or more mobile nodes are selected based upon at least one of active times, active days, a device identifier, an IP address, a device priority, a list of blocked NAIs, and a list of allowed NAIs; and

means for sending one or more communications to two or more mobile nodes contained on the list of active mobile nodes.

12. The apparatus of claim 11, wherein the means for receiving a registration request message further comprises means for receiving a Session/Device Identification Extension uniquely identifying at least one of the one or more mobile nodes.

13. The apparatus of claim 11, wherein the means for receiving a registration request message further comprises means for receiving an indication of a host for at least one of the one or more mobile nodes.

14. The apparatus of claim 11, wherein the means for receiving a registration request message further comprises means for receiving an indication of a host for at least one of the one or more mobile nodes, the indication being a host identification extension comprising a host identifier.

15. The apparatus of claim 11, wherein the means for receiving a registration request message further comprises means for receiving an indication of a host for at least one of the one or more mobile nodes, the indication being a host identification extension comprising a host identifier NAI.

16. The apparatus of claim 11, wherein the means for receiving a registration request message further comprises means for receiving an indication of the length of time at least one of the one or more mobile nodes are authorized for use.

17. The apparatus of claim 11, wherein the list of active mobile nodes comprises at least one of a device identifier, active times, active days, a device priority, a list of blocked NAIs, a list of allowed NAIs, and an IP address.

18. The apparatus of claim 11, wherein the plurality of mobile nodes further comprises at least one fixed node.

19. The apparatus of claim 11 further comprising, means for implementing a unified billing system, wherein a user is jointly billed for at least two of the plurality of mobile nodes.

20. The apparatus of claim 11 further comprising, means for enabling a user to update characteristics for at least one mobile node through an IP-based network interface.
