PROCÉDÉS, SYSTÈMES ET SUPPORTS LISIBLES PAR ORDINATEUR POUR APPLIQUER UNE POLITIQUE D'ABONNÉ À UN FLUX DE DONNÉES DE SERVICE DE RÉSEAU

摘要

Methods, systems, and computer readable media for applying a subscriber based policy to a network service data flow are disclosed. According to one example, the method includes determining, based on message traffic communicated between a user equipment device and an operator network via GTP, a private socket address that identifies the user equipment device and conducting network address translation (NAT) on a spoofed Internet protocol (IP) protocol data unit (PDU) that includes the private socket address in order to derive a corresponding public socket address. The method further includes provisioning, in a network element positioned in the operator network, a mapping record that correlates the private socket address to the public socket address, and utilizing, by the network element, the mapping record to apply at least one subscriber-based policy to received service data flow associated with the user equipment device.
