Systems and methods described herein enable premium session retainability for differentiation of services with respect to network function failures. A first network function of a core network obtains a session retention indicator during establishment of a protocol data unit (PDU) session. The first network function calculates a compute footprint for the first network function to support the PDU session and any other premium sessions currently serviced by the first network function. An orchestration device receives the compute footprint and provisions a second network function based on the compute footprint. The first network function and the second network function perform data replication of state information for the PDU session to allow premium sessions to continue with no or minimal interruption in the event of a failover scenario.

Systems and methods for premium session retainability in core networks

A primary application cloud instance may receive historical usage of an application, may allocate, based on the historical usage, a quantity of cloud resources for enabling the application to be accessed, and may enable the application to be accessed. The primary application cloud instance may provide, to a backup application cloud instance that allocates a minimum quantity of cloud resources for providing a skeletal version of the application, heartbeat and session state information associated with the primary application cloud instance, and the quantity of cloud resources for enabling the application to be accessed. The primary application cloud instance may provide, to the backup application cloud instance, an indication of a failure of the primary application cloud instance, via the heartbeat and session state information, to cause the backup application cloud instance to allocate the quantity of cloud resources and to enable access to the application.

Systems and methods for optimizing resources for applications deployed in primary and backup geographically dispersed cloud environments

Systems and methods described herein enable distribution of a Charging Function group identifier ('CHF-Group-ID') and other CHF selection data to CHF consumers during Protocol Data Unit (PDU) session establishment in a 5G network. A Unified Data Repository (UDR) is provisioned with CHF-Group-ID details for each subscriber of the network. In one aspect, during PDU session establishment, CHF consumers obtain CHF-Group-ID information as part of a subscriber profile that is provided to all CHF consumers. No additional step or hop is needed for the CHF consumers to obtain the CHF-Group-ID. Thus, regionally segmented CHFs can be implemented without replication of data between CHFs in different regional segments and without additional signaling between network functions.

Systems and methods for regional segmentation and selection of charging function

A system described herein may identify a requested communication session between a UE and a network, such as a core of a wireless network. The system may identify Quality of Service ('QoS') information associated with the UE and/or the requested communication session. The QoS information may include or may be based on a network slice identifier, a QoS value, a Service Level Agreement (“SLA”), one or more models associated with UE attributes, or other suitable information. The system may determine a maximum transmission unit (“MTU”) configuration for the UE based on the identified QoS information and/or models that associate UE attributes to MTU configurations. The system may implement the determined MTU configuration, including providing the MTU configuration to one or more gateways or endpoints of the network and/or to the UE. The UE and the network may accordingly use the MTU configuration when communicating via the requested communication session.

Systems and methods for dynamic maximum transmission unit adjustment in a wireless network

Systems and methods described herein provide for User Equipment (UE)-initiated authentication and authorization updates to Network Slice-Specific Authentication and Authorization (NSSAA). A network device in a core network receives a message from a user device outside of the core network, wherein the message includes a request to initiate a NSSAA procedure. The network device initiates the NSSAA procedure in response to the request. The systems and methods also provide for UE-initiated authorization revocation of NSSAA.

In some implementations, a network device may receive a subscription request to subscribe to receive notifications associated with context data related to a registered session associated with a user equipment (UE). The registered session may be associated with a reauthorization timer that is associated with triggering the network device to provide a request for reauthorization of the registered session. The network device may provide, based on an expiration of the reauthorization timer, the request for reauthorization of the registered session.

Systems and methods for reauthorization request notification

A device may receive load data identifying loads of network functions provided by a cloud computing environment, resource data associated with resources of the cloud computing environment, and resource distribution data associated with the resources. The device may perform data analytics on the load data, the resource data, and the resource distribution data to identify, from the network functions, a network function being impacted and to determine that the network function requires resource modification. The device may calculate, based on the data analytics and based on determining that the network function requires resource modification, parameters for the resource modification and may perform one or more actions based on the parameters for the resource modification.

Systems and methods for providing fifth-generation network function on demand resource distribution
