Abstract: A first network node, comprises a memory configured to store computer program code that includes first transmitting code configured to cause a processor to transmit, to a second network node, a bearer context modification request that includes an information element requesting a data usage report. The program code further includes first receiving code configured to cause the processor to receive, from the second network node in response to the information element included in the bearer context modification request, a bearer context modification response and a data usage report. The program code further includes forwarding code configured to cause at least one of said at least one processor to the data usage report to a third network node.

Abstract: A first network node comprises program code including: first receiving code configured to cause at least one of said at least one processor to receive, from a second network node, a UE context modification request; first transmitting code configured to cause at least one of said at least one processor to transmit, to the second network node in response to receiving the context modification request, a context modification response; allocating code configured to cause at least one of said at least one processor to, in response to the UE context modification request, allocate one or more pre-configured grants to the UE, and second receiving code configured to cause at least one of said at least one processor to receive, from the UE in response to the one or more pre-configured grants, first uplink data, before sending a scheduling request to the base station and receiving corresponding UL scheduling grants.

Abstract: An apparatus includes a first processor; and a memory having instructions stored thereon that, when executed by the first processor, cause the apparatus to monitor a flow of data packets on a network plane. The apparatus is also caused to calculate a packet rate of the flow of the data packets. The apparatus is further caused to compare the packet rate with a first threshold value. The apparatus is additionally caused to, in response to determining the packet rate is less than the first threshold value, cause an operating state of a second processor communicatively coupled with the apparatus to change from an active state to a sleep state.

Abstract: In general, the current subject matter relates to handling core network connection failure. In some implementations, an F1 interface can be set up between a centralized unit (CU) of a base station and a distributed unit (DU) of the base station. Setting up the F1 interface can include transmitting core connectivity status information from the CU to the DU, and the core connectivity status information can indicate to the DU whether or not the CU has connectivity with a core network.

Abstract: In general, the current subject matter relates to handling core network connection failure. In some implementations, with a connection down between a gNodeB and a 5G core network, the gNodeB can be caused to be in an active state such that the gNodeB can provide support to Non-Standalone (NSA) user equipments (UEs) with the connection down between the gNodeB and the 5G core network.

Abstract: A method, an apparatus, and a computer program product for scaling of subscriber capacity in a cloud native radio access network (RAN). A processing capacity being assigned to one or more containers in a plurality of containers of a cloud native radio access network for providing communication to at least one user equipment in a plurality of user equipments is determined. The determined processing capacity is compared to at least one predetermined threshold in a plurality of predetermined thresholds. Based on the comparing a determination is made whether to change an assignment of the processing capacity.
