Abstract: Presented herein are techniques to facilitate dual-connectivity support for a user equipment (UE) in a hybrid cell virtualized Radio Access Network (vRAN) architecture. In one example, a method may include obtaining, by a node of a mobile network via a first cell of a RAN, a request for a UE to connect to the mobile network via the first cell in which the RAN includes at least one shared cell and at least one unique cell; determining that the UE is allowed for dual-connectivity operation; and providing a policy to the UE, wherein the policy identifies, for each of one or more applications, one of a shared cell operating mode or a unique cell operating mode that the UE is to utilize for each of the one or more applications.

Abstract: Presented herein are techniques to facilitate fast roaming between a mobile network operator-public (MNO-public) wireless wide area (WWA) access network and an enterprise private WWA access network. In one example, a method is provided that may include generating, by an authentication node, authentication material for a user equipment (UE) based on the UE being connected to a public WWA access network, wherein the public WWA access network is associated with a mobile network operator, and the authentication node and the UE are associated with an enterprise entity; obtaining, by the authentication node, an indication that the UE is attempting to access a private WWA access network associated with the enterprise entity; and providing, by the authentication node, the authentication material for the UE, wherein the authentication material facilitates connection establishment between the UE and the private WWA access network.

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.
