Abstract: System, methods, and computer-readable media for switching a dynamic radio of a single RU between Radio Access Technology (RAT) protocols based on a Software-Defined RAN intelligent controller (SD-RIC). The SD-RIC efficiently assigning RAN resources by converting a radio access point to either 5G or Wi-Fi based on the load conditions and the number of users seen on the network, so that it appropriately servers the customer and end devices. To determine the load conditions may be based on active users on a particular cell, and then the resource utilization cue is a connection latency. A single radio unit includes a primary radio and a secondary radio, each being independently tuned. The primary radio is static while a secondary one can be influenced based on the conditions, turning into N-RU or Wi-Fi.

Abstract: The disclosure provides a method for providing an enterprise gNB for connection to a 5G packet core network. The method includes provisioning the enterprise gNB. The enterprise gNB hosts a local user plane function (L-UPF). The method also includes configuring the 5G packet core network comprising a session management function (SMF) to select the local user plane function to service user equipment (UE) connected to the enterprise gNB.

Abstract: Techniques presented herein may provide Distributed Unit (DU) failover techniques for a virtualized Radio Access Network (vRAN) architecture. In one example, a method may include maintaining, by a management node for a vRAN, service information for a plurality of distributed unit components for the vRAN in which the service information identifies, at least in part, service characteristics and failover rules for the vRAN. The method may further include determining a failure of a particular DU component of the plurality of DU components; and reassigning one or more particular RUs currently assigned to the particular DU component to one or more other DU components based on the service characteristics maintained in the service information and particular failover rules identified in the service information that are associated with each of the one or more particular RUs that are re-assigned.

Abstract: In one example, a user equipment (UE) has a non-Third Generation Partnership Project (non-3GPP) radio transceiver for communication in a local private non-3GPP wireless network and a 3GPP radio transceiver for communication in a 3GPP network, where the 3GPP network may be a public 3GPP network or a local private 3GPP network operative in a shared spectrum according to a system for shared spectrum access. Initially, the UE may operate the 3GPP radio transceiver for communication in the public 3GPP network, without performing regular scanning for the local private 3GPP network. In a scan operation using the non-3GPP radio transceiver, the UE may receive from a non-3GPP access point of the local private non-3GPP wireless network one or more messages including one or more information elements. If an information element indicates presence of the local private 3GPP network, the UE may identify and register with the local private 3GPP network.

Abstract: A radio access network (RAN) entity (e.g. an eNodeB) may be configured to facilitate multicast communication in a local private Third Generation Partnership Project (3GPP) network. The RAN entity may receive a user data packet tunneled in an IP message via one of a plurality of downlink tunnels. The RAN entity may select, from a plurality of stored mappings, one of a plurality of multicast group identifiers that is mapped to an identified one of a plurality of downlink tunnel endpoint identifiers that matches a downlink tunnel endpoint identifier from a tunnel header of the IP message, as well as one of a plurality of sets of UE identifiers that is mapped to the selected multicast group identifier. The RAN may send, for each one of the UE identifiers in the selected set of UE identifiers, the user data packet for transmission to a UE associated with the UE identifier.

Abstract: Techniques are described herein for pairing disaggregated network elements. In one example, a pairing manager obtains an indication to prioritize high availability when pairing disaggregated network elements. The disaggregated network elements include first disaggregated network elements and second disaggregated network elements. The pairing manager obtains, from one or more of the disaggregated network elements, topology information of the disaggregated network elements. Based on the topology information and the indication to prioritize high availability, the pairing manager pairs topologically-adjacent ones of the first disaggregated network elements with different ones of the second disaggregated network elements.

Abstract: Dynamic Open Radio Access Network Radio Unit (O-RU) sharing between multiple tenant Open RAN Distributed Units (O-DU) may be provided. A Near Real Time RAN Intelligent Controller (nRT-RIC) may receive tenant policies for a first tenant and a second tenant. The nRT-RIC may then determine initial sharing templates for the first tenant and the second tenant based on the tenant policies. The nRT-RIC may send the initial sharing templates to a first tenant Distributed Unit (DU) and a second tenant DU. The nRT-RIC may receive operating metrics from the first tenant DU and the second tenant DU. The nRT-RIC may then determine operational factors based on the operating metrics. The nRT-RIC may alter an allocation of resources between the first tenant and the second tenant based on the operational factors. Finally, the nRT-RIC may send the altered allocation of resources to the first tenant DU and the second tenant DU.
