Abstract: A Radio Access Network (RAN) element provides an internet indication to a User Equipment (UE) to enable the UE to quickly obtain internet access. The RAN element determines that the RAN element is connected to at least one gateway that provides public internet access, and broadcasts an internet indication. The RAN element determines that the UE has requested public internet access via the RAN element and provides the UE with public internet access.

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: 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.

Abstract: Presented herein are techniques to facilitate secure communications with an Application Function (AF) for a client device that does not support Authentication and Key Management for Applications (AKMA) functionality. In one example, a method includes obtaining, by a user plane function (UPF), a first uplink data packet from a client device, wherein the first uplink data packet is to be communicated to an application; determining, by the UPF based on the first uplink data packet, whether the client device supports AKMA functionality; based on determining that the client device does not support the AKMA functionality, buffering at least the first uplink data packet by the user plane function and determining whether the application supports the AKMA functionality; and based on determining that the application supports the AKMA functionality, performing AKMA functionality by the UPF for the client device for data communications between the client device and the application.

Abstract: The present technology is directed to routing a user equipment (UE) to a network node, for example, a gNB or ng-eNB that supports a slice requirement of the UE. A first network node can receive a Radio Resource Control (RCC) connection request from a UE, and can determine that a slice requirement of the UE is not supported by the first network node. The first network node can further select a second network node that supports the slice requirement of the UE, and route the UE to connect to the second network node.

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: A user device operates a first data session using a first network slice. The user device obtains a trigger notification from a remote application that identifies a second network slice, and the user device determines that the first network slice and the second network slice are mutually exclusive. The user device ends the first data session on the first network slice and initiates a second data session on the second network slice.

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: 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.

Abstract: Techniques are described herein for dynamic platoon management. The techniques may include obtaining dynamic location data of a vehicle, where the dynamic location data indicates a current or predicted location of the vehicle. Based on the dynamic location data, a platoon of vehicles that is optimal for the vehicle to join may be identified. The vehicle may be dynamically joined to the platoon.
