Abstract: Provided herein are techniques to facilitate service-based network function (NF) selection for roaming scenarios involving multiple home core networks. In one instance, a method may include obtaining, by a visited public land mobile network (PLMN) from a home PLMN that is to provide a first service for a wireless device, service hosting information that identifies a service hosting data network name and a service hosting PLMN that is to provide a second service for the wireless device in which the service hosting information is obtained by the visited PLMN through registration of the wireless device with the home PLMN. Upon determining that a session for the second service is to be established for the wireless device, the method may include performing a NF query to the service hosting PLMN identified from the service hosting information obtained through the registration in order to identify a NF to facilitate the session.

Abstract: A control plane (CP) function for mobility management may receive, from a user equipment (UE), a message which indicates a registration request for registration to a network slice. The CP function may select, as an allowed slice ID, a first slice ID of a first network slice in which to register the UE. The first slice ID has a slice/service type (SST) value indicating an SST and a first slice differentiator (SD) value associated with a first level of service to be provided. The CP function may alternatively select, as the allowed slice ID, a second slice ID of a second network slice in which to register the UE based on unavailability of the slice type associated with the first level of service. The second slice ID has the SST value indicating the slice type and a second SD value associated with a second level of service to be provided.

Abstract: The present disclosure is directed to migrating network traffic from a licensed spectrum to an unlicensed spectrum within the same radio access technology (RAT). In one aspect, a method includes identifying a user device connected to a cellular wireless access technology, over a licensed spectrum; determining whether a condition for switching network traffic associated with the user device to an unlicensed spectrum is triggered; in response to determining that the condition is triggered, determining an unlicensed spectrum to move the network traffic to, the unlicensed spectrum being within a same cell as the licensed spectrum or in a different cell compared to a cell in which the licensed spectrum is; and migrating at least a portion of the network traffic to the unlicensed spectrum while maintaining network connectivity of the user device over the cellular wireless access technology.

Abstract: Provided herein are techniques to facilitate radio access network sharing for a Multi-Operator Core Network (MOCN) environment. In one instance, a method may include obtaining, by a radio node of a shared RAN, home mobile network identifiers that are associated with a home access and mobility management function (AMF) in which the home mobile network identifiers are obtained from a first transit AMF that include first priority values and from a second transit AMF that include second priority values. The method may further include obtaining a control plane communication from a user equipment (UE) including a particular home mobile network identifier, identifying the first transit AMF or the second transit AMF that is associated with a highest priority value for the particular home mobile network identifier; and transmitting the communication to the identified transit AMF that is to proxy control plane communications between the UE and the home AMF.

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: Techniques are provided for operator specific customization of a network service configuration. In some embodiments, an operator defines a mapping between an application executing on a user equipment (UE) and a network service configuration. In some embodiments, the network service configuration indicates whether the application is to be supported via a UPF instance located within the core network or deployed at a network edge. The mapping is then provided to the UE, and passed back to the core network, for example, when the UE establishes a connection on behalf of the UE application. The core network then supports the UE application consistent with the configuration specified by the mapping.

Abstract: The present technology is generally directed to dynamically adding network resources based on an application function (AF) notification. The present technology can determine, by an AF of a service provider, a network congestion on a network, the network congestion indicating that network resources for servicing a user device using services of the service provider do not meet corresponding Quality of Service (QOS) requirements. Further, the present technology can transmit a notification by the AF to a core network of a network provider to request additional network resources to be allocated for servicing the user device, the network provider providing network connectivity for the user device to receive the services provided by the service provider.

In one aspect, a method includes receiving, by the UE and from a home public land mobile network (h-PLMN), a steering of roaming update providing a steering of roaming record. In one aspect, the UE, is configured based on the steering of roaming record, to connect to the non-public network (NPN) when a context of the UE meets time and location requirements. In one aspect, the method includes establishing, by the UE, a session with the NPN when the context of the UE meets the time and location requirements.

Abstract: A network function selectively supports a mobile device with network settings appropriate for the device context of the mobile device. The network function obtains a device profile for the mobile device, which identifies multiple device groups, with each device group being associated with a corresponding set of network settings. The network function selects a device group among the device groups in the device profile based on a device context of the mobile device. Responsive to a notification of the mobile device in a different device context, the network function supports the mobile device with a different set of network settings that cause a Session Management Function (SMF) to reconfigure the user plane for the mobile device.

Abstract: A system and method are provided to selectively increase the reliability for transmission of select data packets that are determined to be important or critical. When the data packets are PDUs arranged in PDU-SETs, a user plane function (UPF) receives the PDU-SETs from a content server, and, based on header information, e.g., the UPF filters the PDU-SETs according to respective reliability levels. For PDU-SETs in the highest reliability level, a manner of transmitting the PDU-SETs is modified to increase reliability of the transmission for at least part of the transmission path. For example, the redundancy of the PDUs in the PDU-SETs can be increased for one or more legs of the transmission path by generating duplicates of the PDUs, which are transmitted together with the original PDUs. Further, reliability can be increased for respective legs by transmitting the PDUs using an acknowledgement mode.

In one aspect, the method also includes locally authenticating, by the controller, the device using stored credential information obtained from the cloud-based authentication component prior to losing the connectivity to the cloud-based authentication component.

Abstract: The present disclosure is directed to systems and techniques for providing service continuity for User Equipment (UE) services associated with certain network slices. In one example, the systems and techniques can receive a registration request from a UE, wherein the registration request includes a requested slice, and determine a current network location of the UE.
