Abstract: A policy enforcement technique may be performed at a network node configured for exposure of services and capabilities, such as a service and capability exposure function (SCEF) or a network exposure function (NEF). In one illustrative example, the network node may receive a message which includes a request for background data transfer from an application server (AS) to a plurality of UEs of a group. The message may include mobile-terminated (MT) data to be delivered, a group ID associated with the group, a total bandwidth for the background data transfer for the group, and a transfer policy ID associated with a transfer policy. The network node may verify whether the total bandwidth for the background data transfer for the group is within a predefined aggregate bandwidth limit indicated in the transfer policy data. The network node may cause the background data to be sent to each one of the plurality of UEs via the mobile network, if the total bandwidth is within the predefined aggregate bandwidth limit. In some implementations, the network node may be configured to facilitate background data transfers and perform policy enforcement for transfers involving both IP data delivery and non-IP data delivery (NIDD).

Abstract: A network function (NF) profile repository function (NPRF) is provided to receive, for each one of a plurality of NF instances of a plurality of different NF types, information associated with the NF instance and store the information in memory. The NPRF may then also receive, from an NF repository function (NRF), a message which indicates a request for information associated with one or more NF instances of an indicated NF type. In response, the NPRF may retrieve, from the memory based on the indicated NF type, information associated with the one or more NF instances. The NPRF may send, to the NRF, a message which indicates a response to the request, where the response includes retrieved information associated with the one or more NF instances.

Abstract: Methods, apparatus, and systems for the process-efficient generation of data records for data communications involving groups or aggregates of user equipment (UE), such as IoT devices, are described. In one illustrative example, for each one of a plurality of UEs associated with a group or aggregation identifier (ID), a request which includes data indicative of a network resource usage event of the UE is received and the data are stored in association with the group or aggregation ID. In response to identifying a predetermined condition, the data indicative of the network resource usage events associated with the group or aggregation ID are aggregated, and a request for generating a data record based on the aggregated data is sent to a data function for generating the data record. The generated data record (e.g. a CDR) may be stored for subsequent retrieval for reporting, analysis, network/communications management, or billing.
