Abstract: A control plane entity selects a subset of a plurality of user plane entities to support a charging session associated with a user based on charging policies for the plurality of user plane entities. The control plane entity allocates portions of a quota for the charging session to the control plane entity and the subset of the plurality of user plane entities based on the charging policies. In some cases, the control plane entity modifies the quotas that are allocated to the control plane entity or the subset of the plurality of user plane entities. Modifying the quotas can include redistributing unused portions of the quotas among the control plane entity and the subset of the plurality of user plane entities, e.g., in response to handover of the user equipment between user plane entities.

Abstract: A system, apparatus, method, and non-transitory computer readable medium for implementing a fault-tolerant multi-NRF network topology may include a network repository function (NRF) device including: at least one processor configured to execute computer readable instructions to cause the NRF device to, broadcast a NRF query to a NRF cluster of a core network, the NRF cluster including a plurality of NRF devices located in a public land mobile network (PLMN); receive NRF query responses from each NRF device of the NRF cluster, the NRF query responses including network configuration information of each NRF device; determine a status of each NRF device based on the network configuration information; determine a list of network function (NF) devices registered with the NRF cluster; receive a NF query request from a first NF device; and transmit a NF query response to the first NF device.
