Abstract: In one illustrated example, automated or semi-automated system operations for Massive IoT (MIoT) deployment may involve the automatic assignment of external IDs, subscriber IDs (e.g. IMSIs), and mobile network IDs (e.g. MSISDNs) to IoT devices of a group, followed by the provisioning of assigned identities at the relevant network nodes and the IoT devices themselves. The process may continue seamlessly with network slice orchestration for the creation of a network slice instance (NSI) and the provisioning of its associated Network Slice Selection Assistance Information (NSSAI) and NSI ID at the relevant network nodes. Network Slice Selection Policies (NSSP) may be derived and sent to a policy function and subsequently to IoT devices of the group. Signaling efficiency may be achieved by performing operations on a group basis.

Abstract: A Unified Data Repository (UDR) proxy obtains first subscriber data from a first UDR of a first network operator, second subscriber data from a second UDR of a second network operator, and third subscriber data from a third UDR of an enterprise. The UDR proxy stores the first subscriber data, the second subscriber data, and the third subscriber data locally. The UDR proxy obtains a request to access a network asset that is accessible through the first network operator. Based on the first subscriber data, the second subscriber data, and the third subscriber data stored locally, the UDR proxy attempts to determine whether the request to access the network asset is authorized to access the network asset. In response to determining that the request to access the network asset is authorized, the UDR proxy permits access to the network asset.

Abstract: A method is provided in one example embodiment and may include determining a predicted average throughput for each of one or more cellular interfaces and adjusting bandwidth for each of the one or more of the cellular interfaces based, at least in part, on the predicted average throughput determined for each of the one or more cellular interfaces. Another method can be provided, which may include determining a variance in path metrics for multiple cellular interfaces and updating a routing table for the cellular interfaces using the determined variance if there is a difference between the determined variance and a previous variance determined for the cellular interfaces. Another method can be provided, which may include monitoring watermark thresholds for a MAC buffer; generating an interrupt when a particular watermark threshold for the MAC buffer is reached; and adjusting enqueueing of uplink packets into the MAC buffer based on the interrupt.
