  • 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: 9060263
    Abstract: A method and article for authenticating a mobile station subscribed to a home network, in a visited network, includes the steps of receiving, at a visited proxy controlled by the visited network, a request to authenticate the mobile station on the visited network. Then, authorizing the mobile station on the visited network based on a parameter in the request and a policy stored on the visited proxy. The proxy communicates a denial of authorization to the visited network when the policy identifies a denial of service and the proxy communicates with the home network the request to authenticate the mobile station on the visited network, when the policy identifies an acceptance of service.

  • Patent number: 8977751
    Abstract: Systems and methods for throttling network usage are disclosed. An exemplary method includes an access device maintaining throttling command interpretation data, receiving a throttling command broadcast over a wide area network, interpreting the throttling command based on the throttling command interpretation data, and conforming at least one operation of the access device to a network usage throttling level in accordance with the interpretation of the throttling command. Corresponding systems and methods are also disclosed.

  • 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.
