Abstract: A system described herein may receive a first request to establish, modify, or remove a plurality of communication sessions between a User Equipment (“UE”) and a network. The system may output, to a policy element of the network (e.g., a Policy Control Function (“PCF”) or a Policy Charging and Rules Function (“PCRF”)), a second request for policies associated with the UE and the plurality of communication sessions, where the second request includes a plurality of communication session identifiers that are each associated with a particular one of the plurality of communication sessions. The system may receive and enforce the requested policy information when establishing, modifying, or removing the requested plurality of communication sessions based on the received particular policy information. The system may communicate with the policy element via an enhanced interface, such as an enhanced N7 interface or an enhanced Npcf interface.

Abstract: A method may include receiving, by a charging function (CHF), a data usage monitoring request associated with use of an application, wherein the data usage monitoring request identifies a data usage threshold. The method may also include transmitting, by the CHF and to a session management function (SMF) or a user plane function (UPF), a message notifying the SMF or UPF of the data usage threshold. The method may further include receiving, from the SMF or UPF, a notification that the data usage threshold has been reached, and sending, by the CHF, a message to a network exposure function (NEF) indicating that the data usage threshold has been reached.

Abstract: A method, a network device, and a non-transitory computer-readable storage medium are described in relation to an detection and autocorrection of stale session information service. The detection and autocorrection service may include the addition of a header, which may indicate date and time information, with a message that has an origination timestamp header. The header may be added to the message by an intermediary network device relative to origin and destination network devices associated with a network procedure. The header may enable detection by a network device of stale session information. The header may enable the network device to determine whether to ignore the message as a duplicate message or use the message to carry out the network procedure. In this way, duplicate messages that may include the same origination timestamp header may be managed and stale information may be detected.

Abstract: A network device receives, from a policy control function (PCF), at least one set of multiple user equipment device (UE)-location based conditional policy rules. The network device selects a first one of the multiple UE-location based conditional policy rules based on a first geographic location of a first UE, and controls data traffic associated with the first UE using the selected first one of the plurality of UE-location based conditional policy rules.

Abstract: Systems and methods described herein include receiving, at a network device, a message including an identifier associated with a subscriber and an identifier associated with a rating group associated with one or more data flows and determining a data quota and one or more usage monitoring thresholds associated with the subscriber. The data quota indicates a first amount of data associated with the rating group that the subscriber is authorized to use during a time period and the one or more usage monitoring thresholds indicate one or more second amounts of data associated with the rating group and one or more service flows that the subscriber is authorized to use during the time period. The network device transmits the data quota and the one or more usage monitoring thresholds, receives data usage information, and processes the data usage information.

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.

Abstract: Systems and methods described herein include receiving, at a network device and from a session management device, a first message that includes a first identifier associated with a subscriber and a second identifier associated with a first service that is charged using an online charging system. The network device transmits a second message that indicates a first time period in which to report data usage associated with the first service and a second time period in which to report data usage associated with one or more second services that are charged using an offline charging system. The network device receives first data usage information associated with the first service after the first time period and second data usage information associated with the one or more second services after the second time period. The network device processes the data usage information.

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, and modifies, responsive to receipt of the notification, the first TCP congestion control parameters to create second TCP congestion control parameters. The network device transmits data to the UE via the second RAN using the second TCP congestion control parameters.

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.
