Abstract: Presented herein are techniques to facilitate providing slice attribute information to a user equipment (UE) for one or more slice types with which the user equipment is allowed to establish one or more session(s). In one example, a method may include obtaining, by a network element, a registration request for connection of a UE to a mobile network; performing an authentication for connection of the UE to the mobile network; and upon successful authentication, providing, by the network element, a registration response to the UE, wherein the registration response identifies one or more network slice types with which the UE is authorized to establish a session and the registration response identifies one of: attribute information for each of the one or more network slice types or network location information from which attribute information for each of the one or more network slice types is to be obtained.

Abstract: A Radio Access Network (RAN) node configures a User Equipment (UE) to provide measurement results for private wireless networks in the neighborhood of the UE. The RAN node registers the UE with a computer network and provides location information about the UE to an Application Function (AF) connected to the computer network. The RAN node obtains a partial identifier that specifies a range of private wireless networks selected by the AF, and sends a request to the UE for measurements associated with the range of private wireless networks.

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: 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: A Third Generation Partnership Project (3GPP) based network, such as an enterprise private 3GPP network, is operative to provide a guest onboarding of a device using a realm-based discovery of an identity provider and a mutual authentication of identity federation peers. A secure connection may be established between the peers so that the device may be authenticated based on credentials associated with a Subscriber Identity Module (SIM) provided by its Mobile Network Operator (MNO). Credentials may be extended to those associated with embedded SIMs (eSIMs), digital certificates from private enterprises, login and passwords, and identities from a wide range of identity providers. After device authentication, the 3GPP-based network is operative to select and enforce access policies according to an identity or other attribute of the device.

Abstract: A network management center includes a Dynamic Host Configuration Protocol (DHCP) server. The network management center obtains from an identity server, client information indicating authentication of a client device in a wireless network that is connected to a network fabric. The network management center obtains from an edge node in the network fabric an Internet Protocol (IP) address request for the client device. The IP address request including a fabric domain identifier associated with the edge node. The network management center allocates an IP address for the client device based on the client information obtained from the identity server and the fabric domain identifier contained in the IP address request obtained from the edge node. The network management center provides to the edge node an Identifier Locator Addressing (ILA) address based on the IP address.

Abstract: Presented herein are techniques to facilitate delivering standalone non-public network (SNPN) credentials from an enterprise authentication server to a user equipment (UE) using an Extensible Authentication Protocol (EAP) process. In one example, a method may include determining, by an authentication server of an enterprise, that a UE for the enterprise is to receive credentials to enable the UE to connect to a SNPN of the enterprise in which the determining is performed based, at least in part, on connection of the UE to an access network that is different than the SNPN for the enterprise; and performing an authentication process with the UE by the authentication server in which the authentication process includes providing the credentials to the UE via a first authentication message and obtaining confirmation from the UE via a second authentication message that indicates successful provisioning of the credentials for the UE.

Abstract: A first access and mobility management function (AMF) in a network receives, from user equipment (UE), a registration request listing a first network slice and a second network slice. Upon determining that the first AMF supports the first, but not the second, network slice, the first AMF causes selection of (i) the first AMF as a session and mobility management (SM)-AMF to perform mobility management, and first session management signaling for the first network slice; and (ii) a second AMF as a session management only (SO)-AMF to perform only second session management signaling for the second network slice. The first AMF, acting as SM-AMF, performs the first session management signaling for a first data session on the first network slice, while the second AMF, acting as SO-AMF, performs only the second session management signaling for a second data session on the second network slice.

Abstract: In one example, an Access Point (AP) configures a first mapping of a first cellular network connection to a first local access network group, and further configures a second mapping of a second cellular network connection to a second local access network group. The AP determines whether a user device is authorized to use the first cellular network connection or the second cellular network connection. If the user device is authorized to use the first cellular network connection, the AP associates, for the user device, a first user device identifier with the first local access network group. If the user device is authorized to use the second cellular network connection, the AP associates, for the user device, a second user device identifier with the second local access network group.
