  • Patent number: 9148777
    Abstract: Exemplary inter-network profile repository interworking systems and methods are disclosed. An exemplary system includes an interface facility that interfaces with a home subscriber server (“HSS”) of a long term evolution (“LTE”) communications network and a home location register (“HLR”) of an alternate communications network, the HSS and the HLR maintaining separate profiles associated with a user device configured to access the LTE communications network and the alternate communications network. The exemplary system further includes a synchronization facility communicatively coupled to the interface facility and that synchronizes profile data associated with the user device across the separate profiles maintained by the HSS and the HLR. Corresponding systems and methods are also disclosed.

  • Patent number: 8892068
    Abstract: A subscriber device receives a message from a network device external to the subscriber device, where the network device implements a first metering engine that meters usage of a network service by a subscriber using the subscriber device and where the message includes the subscriber's usage data. The subscriber device includes a second usage metering engine that receives the subscriber's usage data from the usage synchronization unit, and performs real-time metering of the subscriber's usage of the network service, based on the subscriber's usage data received from the network device and independently of the first metering engine of the network device, to generate real-time usage metering data. The second usage metering engine further outputs the real-time usage metering data to a display at the subscriber device.

  • Patent number: 8321565
    Abstract: Systems and methods for throttling network usage are disclosed. An exemplary method includes at least one network device monitoring usage of a wide area network, selecting a throttling command based on the monitored usage of the wide area network, and broadcasting the throttling command to a plurality of access devices connected to the wide area network. The throttling command is configured for interpretation and use by each access device within the plurality of access devices to conform at least one operation to a network usage throttling level in accordance with the interpretation of the throttling command. Corresponding systems and methods are also disclosed.
