Abstract: Presented herein are techniques to facilitate extending a multiple access Protocol Data Unit (PDU) session and Access Traffic Steering, Switching, and Splitting Low-Layer (ATSSS-LL) policies to an enterprise network. In one example, a method may include obtaining a request for an ATSSS-LL policy for a user equipment (UE) for establishing a multiple access protocol data unit session for the UE via a wireless wide area access network for an enterprise network; and providing to the UE one or more ATSSS-LL rules for the ATSSS-LL policy, an Internet Protocol (IP) address for the multiple access protocol data unit session for the UE, and an identifier for the multiple access protocol data unit session for the UE in which the IP address is utilized for a wireless local area access network connection for the UE established via a wireless local area access network of the enterprise network.

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.

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: Techniques and mechanisms for a soft migration from an initial or source Spectrum Access System (SAS) of a source SAS provider to a destination SAS of a destination SAS provider for a base station operative to serve as a Citizens Broadband Radio Service Device (CBSD) in a Citizens Broadband Radio Service (CBRS) network are described. While the base station operates to facilitate communications for one or more user equipments (UEs) and is registered with the source SAS for spectrum access, the base station may communicate in one or more message exchanges for registering with the destination SAS and for receiving from the destination SAS a grant for spectrum access to spectrum according to a plurality of operating parameters. After communicating in a message exchange with the destination SAS in a heartbeat procedure for receiving an authorization to use the granted spectrum, the base station may deregister with the source SAS.

Abstract: Presented herein are techniques to facilitate electronic profile management by an enterprise entity in which the enterprise entity can utilize an enterprise infrastructure to provision one or more electronic profiles for one or more enterprise device(s). In one example, a method is provided that may include determining, by a management node of an enterprise network, whether a user equipment (UE) supports an electronic profile capability and a wireless wide area access network connectivity capability; and based on determining that the UE supports the electronic profile capability and the wireless wide area access network connectivity capability, providing, by the management node, at least one electronic profile to the UE via a wireless local area access network of the enterprise network, wherein the at least one electronic profile enables the UE to connect to at least one wireless wide area access network of the enterprise network.

Abstract: Presented herein are techniques to prevent and/or minimize user equipment (UE) service disruptions in a virtualized Radio Access Network (vRAN) architecture. In one example, a method may include establishing, via a central unit of a vRAN, a first radio connection for a UE via a first cell belonging to a first shared cell for the vRAN; determining that the UE is dual connectivity capable; instructing the UE to perform measurements for one or more other cells belonging to one or more other shared cells that have available capacity; obtaining measurement information from the UE for the one or more other cells; determining, based on the measurement information, a second cell among the one or more other cells having a highest measured signal strength; and establishing a second radio connection for the UE via the second cell belonging to the second shared cell.

Abstract: Systems and methods for providing access prioritization to a private Long Term Evolution (LTE) network operating in a Citizens Broadband Radio Service (CBRS) spectrum include receiving, at a network device of the private Long Term Evolution (LTE) network, a functional group associated with a user equipment (UE) and a traffic load of a cell of the private LTE network associated with the UE. An access priority associated with the functional group and the traffic load is determined and provided to a CBRS access point (AP) which controls access to the cell. The access priority indicates to the CBRS AP a priority with which the UE is allowed to access the cell and can include a high priority, a low priority, or no access indication.

Abstract: Systems and methods herein can synchronize 802.11ax Uplink (UL) and Downlink (DL) Orthogonal Frequency-Division Multiple Access (OFDMA) schedules between adjacent APs that have overlapping BSSs, which may not be solved by BSS coloring. The method includes several stages. First, the APs detect RF interference from APs with overlapping BSSs. Then, the APs conduct time synchronization between these APs. The various APs can then elect a master scheduler. The master scheduler creates and implements a master schedule between these APs to coordinate use of the radio resource.

Abstract: The present disclosure provides systems and methods for dynamically adjusting cell coverage sensitivity to address asymmetry of wireless cells that affect upstream and downstream traffic mismatch. In one aspect, a method includes estimating, at a network controller, one or more packet demodulation thresholds for an access point; sending, by the network controller, the one or more packet demodulation thresholds to the access point; receiving, from the access point, collected statistic, the collected statistics being link performance characteristics between the access point and one or more endpoints associated with the access point measured by one or more sensors associated with the access point; updating, at the network controller, the one or more packet demodulation thresholds based on the collected statistics to yield an updated packet demodulation threshold; and configuring, by the network controller, the access point with the updated demodulation threshold.

Abstract: Presented herein are techniques to provide for the ability to utilize 3GPP-generated Session Keys that can be generated via a primary authentication or a secondary authentication process for a user equipment (UE) via a private wireless wide area (WWA) access network in which the keys can be leveraged to facilitate connection of the UE to a wireless local area (WLA) access network. In one example, a method may include obtaining a request to authenticate a UE for connection to a WWA access network; determining that the UE is capable of a Fast Transition (FT) capability; authenticating the UE for connection to the WWA access in which, based on the FT capability, the authenticating includes generating a root security key for the UE; and upon determining that the UE is attempting to access the WLA access network, providing the root security key for the UE to the WLA access network.
