  • Patent number: 10148614
    Abstract: 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.

  • Patent number: 8681622
    Abstract: A system for congestion control in a mobile communications network includes a monitoring module configured to monitor message traffic associated with a cell in a mobile communications network. The message traffic includes control plane and user plane messages. The monitoring module determines, based on the message traffic, whether a predetermined congestion threshold associated with the cell in the mobile communications network has been crossed. In response to the threshold being crossed, the monitoring module generates a cell congestion notification message that includes the identity of subscribers that are contributing to the congestion. A policy server receives the cell congestion notification message and generates a PCC rule that modifies the policy of the one or more identified subscribers and for communicating the PCC rule to a PCEF.
