Abstract:
1. A method of operating a network access control system to manage access to a communication network, the method comprising: receiving a failure notification transmitted from a service node indicating a failure of a wireless communication device to pass an authentication when attempting to register with the communication network, wherein the notification includes a device identifier that identifies the wireless communication device; retrieving device information, network data, and a user profile associated with the wireless communication device based on the device identifier; processing the device information, the network data, and the user profile to generate a network access score for the wireless communication device; if the network access score exceeds a priority threshold, transferring a priority notification for delivery to the service node that instructs the service node to bypass the authentication for the wireless communication device; if the network access score exceeds a legitimate user threshold but does not exceed the priority threshold, transferring an access notification for delivery to the service node that instructs the service node to bypass the authentication for the wireless communication device and monitoring subsequent usage of the wireless communication device for fraudulent activity; and if the network access score does not exceed the legitimate user threshold, transferring a suspect notification for delivery to the service node that instructs the service node to maintain the authentication for the wireless communication device.
