On-demand dynamically updated user database and AAA function for high reliability networks
DCFirst Claim
1. A method of maintaining authentication, authorization and accounting (AAA) functionality for a wireless communications network having a plurality of nodes which are AAA function capable, said method comprising:
- (a) selecting two of the plurality of nodes to be active nodes;
(b) activating the AAA functions of the active nodes;
(c) monitoring the active nodes to determine if one of the active nodes gets disconnected from the network;
(d) if one of the active nodes gets disconnected from the network;
selecting another of the plurality of nodes to become an active node;
(e) activating the AAA functions of the node selected in step (d); and
,(f) informing the plurality of nodes that the node selected in step (d) has its AAA functions activated.

Abstract
A method is provided for operating a wireless communication network (10) including a plurality of nodes (12a, 12b, 12c, 12d, 12e). Each of the nodes has a user database and is equipped to conduct authentication, authorization and accounting (AAA) functions for the network (10). The method includes employing a subset (optionally, two) of the plurality of nodes (12a, 12b, 12c, 12d, 12e) as active nodes. The active nodes use their respective user databases to conduct the AAA functions for the network (10). Changes to the user databases for the active nodes are logged to thereby update the same to reflect changes in information contained therein, and the user databases of the active nodes are synchronized. The active nodes are monitored to detect if one becomes disconnected from the network, and, if one of the active nodes becomes disconnected from the network, another of the plurality of nodes (12a, 12b, 12c, 12d, 12e) is employed as an active node.

11. A wireless communication network comprising:
a plurality of nodes, each node being initially provisioned with a user database and equipped to carry out authentication, authorization and accounting (AAA) functions for the network by employing their respective user database, said plurality of nodes including; a subset thereof which are active nodes that in fact carry out the AAA functions for the network by employing their respective user databases, said active nodes monitoring one another to detect if an active node becomes disconnected from the network, wherein when one is determined to be disconnected from the network another of the plurality of nodes is selected to be an active node and the network informed thereof. - View Dependent Claims (12, 13, 14, 15, 16, 17)
