  • Patent number: 11616711
    Abstract: A network device may provide heartbeat requests to a plurality of network function producers, and may set states of the plurality of network function producers to suspended based on not receiving responses to the heartbeat requests after a predetermined time. The network device may receive, from a network function consumer, a discovery request requesting identification of network function producers providing a service or with a network function type, and may determine, based on the discovery request, that none of the plurality of network function producers are available based on the states of the plurality of network function producers being set to suspended. The network device may provide, to the network function consumer, a discovery response that includes a list of the plurality of network function producers with status indicators set to active.

  • Patent number: 11576082
    Abstract: A network device for a mobile carrier network sends, to a third-party content platform, a client message including a first dedicated subscription parameter extension. The first dedicated subscription parameter extension indicates one or more subscription parameters for a data flow between a user equipment (UE) device that originated the client message and the third-party content platform. The network device receives, from the third-party content platform, a server message including a second dedicated subscription parameter extension. The second dedicated subscription parameter extension confirms the third-party content platform will abide by the one or more subscription parameters. The network device generates, based on the one or more subscription parameters, a policy enforcement rule for the data flow that relies, at least in part, on cooperation of the third-party content platform.

  • Patent number: 11503508
    Abstract: A device receives instructions to update a field that defines a coverage area within a network. The device updates, based on receiving the instructions, the field to include a set of identifiers that are associated with a group of base stations within the coverage area. The device determines that a user equipment (UE), that is connected to the network, qualifies for the expanded data usage permissions based on account information associated with the UE including a particular identifier that allows the UE to utilize the expanded data usage permissions. The device provides, to another device, a request for data usage information that reflects the expanded data usage permissions. The device causes the data usage information to be applied to the UE.

  • Patent number: 11489970
    Abstract: A first network device may receive a protocol data unit (PDU) session establishment or modification request, and may perform one or more actions based on the PDU session establishment or modification request. The first network device may receive, based on performing the one or more actions, a first message indicating that the PDU session is authenticated and authorized, and may select a second network device associated with establishing or modifying a management policy for the PDU session. The first network device may receive, from the second network device, a second message indicating whether to wait for receipt of a charging data response, to a charging data request, before interacting with a third network device, and may provide the charging data request to a fourth network device while interacting with the third network device when the second message indicates not to wait for receipt of the charging data response.

  • Patent number: 11350306
    Abstract: A system may receive an indication that a user device is connecting to a network and determine, based on a profile associated with the user device, that a priority associated with the user device is to be modified when congestion associated with the network reaches a level. The system may send, to a base station, a first request to monitor the congestion associated with the network. The system may receive, from the base station, an indication that the congestion associated with the network has reached the level. The system may send, to the base station, a second request to modify the priority associated with the user device when the congestion associated with the network is at the level.

  • Publication number: 20220045953
    Abstract: A network device transmits data to a user equipment (UE) via a first Radio Access Network (RAN) using first Transmission Control Protocol (TCP) congestion control parameters. The network device receives a notification message indicating that the UE has moved from the first RAN to a second RAN. The network device modifies, responsive to receipt of the notification, the first TCP congestion control parameters to create second TCP congestion control parameters, where the first TCP congestion control parameters include a first slow start threshold (ssthresh), and wherein the second TCP congestion control parameters include a second ssthresh that is different than the first ssthresh. The network device transmits data to the UE via the second RAN using the second TCP congestion control parameters.

  • Patent number: 11184746
    Abstract: A system described herein may track usage, on a per-User Equipment (“UE”) basis, in systems that provide for simultaneous connectivity to a given UE via multiple base stations. A cycle cutoff time may be determined, a master base station (to which the UE is connected) may be notified of the cycle cutoff time, and the master base station may notify one or more secondary base stations (to which the UE is connected) of the cycle cutoff time. The master base station and/or the one or more secondary base stations may track usage, of the UE, until the cycle cutoff time, and may report the usage such that the usage via each of the base stations may be able to be determined.

  • Patent number: 11165912
    Abstract: A device obtains and stores presence reporting area (PRA) data, including an area identifier, an event start time, and an event end time. The device receives, at a first point in time, an indication that a user device is present in an area identified by the area identifier. The device determines whether the first point in time is at or between the event start time and the event end time, and selectively reports a presence of the user device in the area based on a result of determining whether the first point in time is at or between the event start time and the event end time.
