Automatically syncing GTP roaming firewall device policies over a data communication network for network security over mobile devices roaming data services on a carrier network

Abstract:

A GTP firewall device registers with a cloud-based GTP GSN objects server to receive IR.21 records for each of a plurality of carriers for which roaming data services are authorized for roaming mobile devices of the plurality of carriers. The cloud-based GTP GSN objects server distributes IR.21 records and updates to the plurality of carriers. The GTP firewall device receives substantially real-time updates to the IP addresses for IR.21 records of carriers from the cloud-based GTP GSN objects server. The updates are responsive to addition of new IP addresses or removal of deleted IP address by a carrier at an IR.21 IP address server, for subsequent authorizations.
