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 includes operating a telecommunications network routing node in a learn mode in which traffic from foreign mobility management nodes is received and identities of the foreign mobility management nodes are learned and used to populate a security database maintained by the telecommunications network routing node. The method further includes operating the telecommunications network routing node in a test mode to dynamically learn foreign mobility management node security status and maintaining the security status for the foreign mobility management nodes in the security database. The method further includes operating the telecommunications network routing node in an active mode to filter traffic from the foreign mobility management nodes using the dynamically learned node identities and security statuses.
