Dynamic learning and use of foreign telecommunications network mobility management node information for security screening

摘要

A method for dynamically learning and using foreign mobility management node information for telecommunications network security screening comprises operating the telecommunications network routing node in learning mode, in learning mode from the foreign mobility management node. Traffic is received, the identity of the foreign mobility management node is learned, and it is used to populate the security database maintained by the telecommunications network routing node. The method further comprises operating the telecommunications network routing node in test mode to dynamically learn the foreign mobility management node security status and keeping the security status for the foreign mobility management node in the security database. The method further comprises operating the telecommunications network routing node in active mode to filter traffic from foreign mobility management nodes using dynamically learned node identities and security statuses.
