Abstract: Various implementations disclosed herein enable controlling access to networks. In various implementations, a method of controlling access to a network is performed by a computing device including one or more processors, and a non-transitory memory. In various implementations, the method includes obtaining an indication that a mobile device having access to a first network utilizing a first radio access technology (RAT) has requested access to a second network utilizing a second RAT. In some implementations, the method includes determining whether the access to the first network satisfies an authentication criterion associated with the second network. In some implementations, the method includes granting the mobile device access to the second network in response to determining that the access to the first network satisfies the authentication criterion associated with the second network. In some implementations, accessing the second network via the authentication criterion satisfies an operating threshold associated with the mobile device.

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: Systems, methods, and computer-readable media are disclosed for facilitating bi-directional edge proxy-to-edge proxy communications across an enterprise firewall in 5G service-based architecture. In one aspect, a method includes receiving a subscription request from a user device to operate on a visited private network; determining that the user device is associated with a home network; and establishing a communication protocol between a security edge protection proxy of the visited private network and a security edge protection proxy of the home network, wherein the communication protocol enables bi-directional exchange of roaming signals between the visited private network and the home network while user device is operating on the visited private network.

Abstract: Systems, methods, and computer-readable media for radio resource management in a Citizens Broadband Radio Service (CBRS) network include one or more CBRS devices (CBSDs) which can obtain a group type associated with the CBSDs and their associated Radio Environment Map (REM) reports of one or more frequency channels of the CBRS network. The group type and the REM reports may be provided to a Self-Organizing Network (SON) manager of the CBRS network, where the SON manager may determine and provide to the CBSDs, one or more of a channel utilization information, transmission power, or mobility load management information for the CBSD, based on the group type and the REM reports.

Abstract: Techniques are described to provide for authentication and subscription management that are decoupled from a Home Subscriber Server (HSS). In one example, a method includes providing a device profile at an authentication function, wherein the device profile comprises identification information for a device for a plurality of access types including a first identifier for the device associated with a cellular access and a second identifier for the device associated with a wireless local area network access; obtaining an access request message associated with the device for the cellular access, wherein the access request message comprises the first identifier and an authentication attribute; generating authentication information for authenticating the device for the cellular access based, at least in part, on the authentication attribute; and generating, for transmission, an access accept message for the cellular access, wherein the access accept message comprises the first identifier, the second identifier, and the authentication information.

Abstract: Presented herein are techniques to facilitate wireless authorization based on in-line assurance and tariffing information. In one example, a method may include determining, by a roaming subscriber, that a visited network is a chargeable network; querying, by the roaming subscriber, the visited network for charging policies for at least two identity realms; obtaining, by the roaming subscriber, charging policy metadata associated with the charging policies for the at least two identity realms; selecting, by the roaming subscriber, an identity realm through which to connect to the visited network based on the charging policy metadata for the at least two identity realms; and connecting to the visited network using the selected identity realm.

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 the configuration of hybrid cells to support shared cell and unique cell operating modes for user equipment. In one example, a method may include obtaining a registration request for a user equipment (UE) in which the mobile network includes a radio access network (RAN) comprising a plurality of radio units (RUs) in which each RU provides a shared cell that is shared with at least one other RU and each RU also provides a unique cell that is not shared with any other RU. The method may further include determining an operating mode for the UE in which the operating mode indicates whether the UE is to operate in a shared cell or a unique cell operating mode, and facilitating connection of the UE to one of the shared cell or the unique cell of an RU based on the operating mode.
