Abstract: Presented herein are techniques to facilitate wireless wide area (WWA) virtualized Radio Access Network (vRAN) (e.g., 5G) to wireless local area (WLA) RAN (e.g., Wi-Fi) steering or WLA RAN to WWA vRAN steering for one or more UE. In one example, a method may include obtaining first performance metrics associated with links of a WWA vRAN (e.g., fronthaul, midhaul, and backhaul links); obtaining second performance metrics associated with links WLA RAN (e.g., backhaul links); and in response to determining that one of the WWA vRAN is experiencing degraded performance based on the first performance metrics or the WLA RAN the second performance metrics, activating a steering event that causes, at least in part, an indication to be communicated to a UE to cause the UE to connect to the WWA vRAN or the WLA RAN that is not experiencing degraded performance.

Abstract: Techniques for dynamically negotiating a service legal agreement (SLA) between a roaming device and a visited network (VN) in an identity federation. An identity profile provided to a user device by an identity provider (IDP) is accessed by the user device. The identity profile includes a first SLA criteria. An advertisement from the VN indicating one or more SLAs supported by the VN is received at the user device. The advertisement is received before the user device has associated with the VN. The IDP and the VN are part of a same identity federation. It is determined that the SLA supported by the VN satisfies the first SLA criteria. Upon that determination, an acceptance is transmitted by the user device to the VN, and the user device is associated with the VN.

Abstract: Presented herein are techniques to support handovers in hybrid cell configuration environments. In one example, a method may include determining that a user equipment (UE) is connected to a first shared cell or a first unique cell of a radio access network; and causing a handover for the UE to a second shared cell or a second unique cell of the radio access network based on whether the UE is connected to the first shared cell or the first unique cell, wherein the handover is performed between one of the first shared cell and the second shared cell or the first unique cell and the second unique cell.

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.

Abstract: The presently claimed disclosure is directed to methods that may be implemented at a computer. Methods and systems consistent with the present disclosure may include extending protocols associated with authenticating client (i.e. supplicant) devices and with authorizing those supplicant devices to access a wireless network. These methods may include sending data relating to the failure of an authentication and/or an authorization process to a supplicant device attempting to access a wireless network. Methods discussed within may include securely sending failure codes or reasons to a supplicant device that identify why an authentication or authorization process failed. These methods may include sending messages between a supplicant device, an authenticator device, and an authentication and authorization server. After a first failure, the supplicant device may be able to access the wireless network after a reason or code of that failure has been reported to the supplicant device.

Abstract: Techniques are described herein for providing radio resource ownership indicators in charging records for a charging function. In one example, a method may include determining, by a session management node of a mobile network, that a user equipment is utilizing a particular radio resource of a mobile network resource for a Protocol Data Unit (PDU) session of the user equipment, wherein the mobile network resource is capable of being utilized via a plurality of radio resources and the particular radio resources is associated with an enterprise entity; and reporting charging information for the PDU session of the user equipment to a charging function of the mobile network to facilitate storing a charging record for the user equipment that is to include an identifier of the enterprise entity that is associated with the particular radio resource.

Abstract: Dynamic roaming partner prioritization based on service quality feedback may be provided. First, a server associated with an enterprise may receive performance data and location data for each of a plurality of service provider networks from a plurality of end use devices associated with the enterprise. Next, the server may assign a ranking to a plurality of service providers by location based upon information. The information may comprise the received performance data and the location data corresponding to each of the plurality of service provider networks. The server may then push the ranking to a first end use device.
