Abstract

The invention includes a method and apparatus for authenticating a visiting node in a wireless network. A method includes receiving a request to transfer a user database of a visiting node, obtaining the visiting node user database from the visiting node in response to a determination to update a master user database to include the visiting node user database, and merging the visiting node user database with the master user database. The request to transfer the visiting node user database is received, from the visiting node, at a primary authentication node of the network. The visiting node user database includes entries for users associated with the visiting node. The master user database includes entries for users associated with nodes authenticated by the primary authentication node of the network.

Claims

1. A method for enabling a visiting node providing a wireless communication network to join a network including a plurality of nodes, the method comprising:

receiving, from the visiting node, a request to transfer a user database of the visiting node, wherein the visiting node user database includes user entries for users associated with the visiting node;

in response to a determination to update a master user database associated with the network to include the visiting node user database, obtaining the visiting node user database from the visiting node; and

merging the visiting node user database with the master user database, thereby joining the wireless communication network provided by the visiting node to the network including the plurality of nodes.

2. The method of claim 1, wherein the request to transfer the visiting node user database includes an origin identifier of the visiting node user database and a version number of the visiting node user database.

3. The method of claim 1, wherein obtaining the visiting node user database from the visiting node comprises:

initiating, to the visiting node, a request for the visiting node user database; and

receiving the visiting node user database from the visiting node.

4. The method of claim 1, wherein merging the visiting node user database with the master user database comprises:

adding at least one of the user entries of the visiting node user database to the master user database.

5. The method of claim 1, wherein each of the user entries includes user authentication information and at least one of user authorization information and user quality-of-service information.

6. The method of claim 1, wherein the visiting node comprises a base station.

7. The method of claim 1, wherein the master user database includes user entries for users associated with existing nodes of the network.

8. The method of claim 1, wherein the master user database supports a primary AAA server for the network.

9. The method of claim 1, further comprising:

receiving, from one of the users of the visiting node, a request to access the network;

in response to identifying, in the master user database, a user entry associated with the one of the users of the visiting node, authenticating the one of the users of the visiting node; and

providing access to the network for the one of the users of the visiting node.

10. An apparatus for enabling a visiting node providing a wireless communication network to join a network, including a plurality of nodes, the apparatus comprising:

processor configured to perform;

means for receiving, from the visiting node, a request to transfer a user database of the visiting node, wherein the visiting node user database includes user entries for users associated with the visiting node;

means for obtaining the visiting node user database from the visiting node in response to a determination to update a master user database associated with the network to include the visiting node user database; and

means for merging the visiting node user database with the master user database thereby joining the wireless communication network provided by the visiting node to the network including the plurality of nodes.

11. The apparatus of claim 10, wherein the request to transfer the visiting node user database includes an origin identifier of the visiting node user database and a version number of the visiting node user database.

12. The apparatus of claim 10, wherein the means for obtaining the visiting node user database from the visiting node comprises:

means for initiating, to the visiting node, a request for the visiting node user database; and

means for receiving the visiting node user database from the visiting node.

13. The apparatus of claim 10, wherein the means for merging the visiting node user database with the master user database comprises:

means for adding at least one of the user entries of the visiting node user database to the master user database.

14. The apparatus of claim 10, wherein each of the user entries includes user authentication information and at least one of user authorization information and user quality-of-service information.

15. The apparatus of claim 10, wherein the visiting node comprises a base station.

16. The apparatus of claim 10, wherein the master user database includes user entries for users associated with existing nodes of the network.

17. The apparatus of claim 10, wherein the master user database supports a primary AAA server for the network.

18. The apparatus of claim 10, further comprising:

means for receiving, from one of the users of the visiting node, a request to access the network;

means for authenticating the one of the users of the visiting node in response to identifying, in the master user database, a user entry associated with the one of the users of the visiting node; and

means for providing access to the network for the one of the users of the visiting node.

19. A non-transitory computer readable medium storing a software program, that, when executed by a computer, causes the computer to perform a method comprising:

receiving, from a visiting node providing a wireless communication network, a request to transfer a user database of the visiting node, wherein the visiting node user database includes user entries for users associated with the visiting node;

in response to a determination to update a master user database associated with the network to include the visiting node user database, obtaining the visiting node user database from the visiting node; and

merging the visiting node user database with the master user database thereby joining the wireless communication network provided by the visiting node to the network.

20. The computer readable medium of claim 19, further comprising:

receiving, from one of the users of the visiting node, a request to access the network;

in response to identifying, in the master user database, a user entry associated with the one of the users of the visiting node, authenticating the one of the users of the visiting node; and

providing access to the network for the one of the users of the visiting node.
