ABSTRACT:
A method and system for authentication of a mobile device that includes a mobile device and a network element in a communications network. The network element may be a call state control function. If the network element detects an incorrect event related to a mobile device, the network element shortens a registration validity time for the mobile device and sends the mobile device a notification to re-authenticate. The incorrect event can be, for example, an incorrect authentication response, an incorrect action by the mobile device, a session over a time maximum, traffic generated being over a maximum, or credit run out. The mobile device is de-registered if the mobile device fails to re-authenticate within the shortened registration validity time, and re-registered if the mobile device re-authenticates within the shortened registration validity time. The registration validity time for the mobile device is extended after re-registration.
