Abstract: Presented herein are techniques to provide network slice admission control in a mobile network. In one example, a method may include obtaining, by an access management element of a mobile network, a registration request from a user equipment; determining, based on the registration request, for each of one or more network slices whether there is: available registration capacity for each network slice for the user equipment based on a registration quota configured for each network slice, available session capacity for each network slice based on a session quota configured for each network slice, and available bit rate capacity for each slice based on a maximum bit rate amount configured for each network slice; and providing, based on the determining, a registration indication to the user equipment for each network slice indicating whether the user equipment is or is not allowed registration for each of the network slices.

Abstract: Techniques are described to provide open access in a neutral host environment. In one example, a method includes obtaining, by a mobility management node of a neutral host network, a network connectivity request from a user equipment, wherein the network connectivity request comprises an indication of a preferred service provider to which the user equipment is to be connected; determining, by the mobility management node, that the preferred service provider provides non-subscription-based network connectivity for the neutral host network; based on determining that the preferred service provider provides non-subscription-based network connectivity for the neutral host network, establishing secure communications for the user equipment, wherein the secure communications are established for the user equipment without authenticating an identity of user equipment; and providing network connectivity between the user equipment and the preferred service provider upon establishing the secure communications.

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: 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 the device context of the mobile device. The network function directs at least one network function in the network to support the mobile device with a set of network settings corresponding to the selected device group.

Abstract: An enterprise private network includes a simplified Third Generation Partnership Project (3GPP) core architecture for interworking between an Evolved Packet System (EPS) and a Fifth Generation (5G) system (5GS). The architecture includes an Evolved Packet Core (EPC) control plane (CP) (EPC CP) unit and a 5G core (5GC) CP (5GC CP) unit. The 5GC CP unit receives, from the EPC CP unit via an N26 interface, a message indicating a forward relocation request responsive to an indication of a handover of a Packet Data Network (PDN) connection at a user plane node from the EPS to the 5GS. The 5GC CP node establishes a Protocol Data Unit (PDU) session corresponding to the PDN connection based on PDN connection information in the message, which includes establishing a Quality of Service (QoS) Flow corresponding to an EPS bearer, and manages the PDU session at the user plane node.

Abstract: Presented herein are techniques to facilitate resiliency, overload control, and/or the like for an Access and Mobility Management Function (AMF) in a Third Generation Partnership Project (3GPP) mobile network architecture. In one instance, a method is provided that includes initiating, by a buddy AMF, a heartbeat exchange with a primary AMF. The method may further include identifying a status condition for the primary AMF by the buddy AMF based on the heartbeat exchange and providing a status indication to a radio access network node by the buddy AMF based on the status condition for the primary AMF.

Abstract: Methods are provided for extending sponsored Wi-Fi guest access capability to other enterprise tools and/or access technologies such as private access networks including private LTE and 5G networks. The methods include a controller detecting a user equipment (UE) that is connected to a guest access service provided by a wireless local access network (WLAN) and generating a profile for the guest access service. The methods further include the controller providing, to the UE, the profile to cause the UE to connect to the guest access service provided by another access network.

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 described to provide ultra-reliability for cellular vehicle-to-everything (C-V2X) PC5 communications, including Network Assisted mode and Autonomous mode communications. In one example, a method includes receiving, by a radio unit of a system, a communication from a user equipment, such as a V2X-UE, wherein the communication comprises a data packet, a Layer 2 destination identifier, and an indication that the data packet is associated with a transmission type; determining whether transmission for the data packet is allowed for the transmission type; based on determining that transmission for the data packet is allowed for the transmission type, communicating a response to the UE, wherein the response provides a confirmation to the UE that the data packet was received by the radio unit and that the transmission type can be performed by the radio unit; and transmitting, by the radio unit, the data packet to one or more other UEs.
