  • Patent number: 10820236
    Abstract: Systems and methods allow a mobile carrier to inform a content provider of data flow restrictions associated with a subscriber's account so that the carrier and the content provider can cooperate to limit data flows without resorting to the inefficiencies of throttling by the carrier. A network device for the carrier network sends, to a third-party content platform, a client message including a first dedicated subscription parameter extension. The first extension indicates one or more subscription parameters for a data flow between user equipment 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 extension confirms the third-party content platform will abide by the subscription parameters. The network device generates, based on the subscription parameters, a policy enforcement rule for the data flow that relies on cooperation of the third-party content platform.

  • Patent number: 10772005
    Abstract: A system described herein may provide a mechanism for accurately tracking data usage across multiple User Plane Function (“UPF”) devices in a telecommunications network. For example, different types of traffic may be handled by UPFs (e.g., may be dropped or forwarded), and the UPFs may be able to report the dropping of specific types of traffic, without needing to perform deep packet inspection (“DPI”). Header information may be passed from an upstream UPF to a downstream UPF with the traffic, where the header information indicates rules and/or policies that were applied by the upstream UPF. The downstream UPF may identify the rules and/or policies from the upstream UPF, and may use this information when reporting usage to a Session Management Function (“SMF”).
