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: A user plane function (UPF) node may receive a packet for traffic associated with a user equipment (UE). During packet classification, the UPF node may identify that a packet filter for the packet is not found in a packet filter set of an existing Quality of Service (QoS) Flow. In response, the UPF node may configure the packet filter in the packet filter set of the QoS Flow based on a flow tuple of the packet. The UPF node may send, to a control plane function node, a message which indicates a request for adding the flow tuple to the QoS Flow. The message may be for triggering communication of a message which indicates a session modification command for receipt by the UE, for adding an uplink packet filter that is based on the flow tuple for the QoS Flow.

Abstract: Techniques are described for extending a cellular quality of service bearer through an enterprise fabric network. In one example, a method obtaining, by a first switch of a network, a packet to be delivered to a client connected to the network via a cellular access point; identifying quality of service (QoS) bearer information associated with the packet, wherein the QoS bearer information is associated with a radio access bearer for the client and the QoS bearer information comprises a bearer indicator and a QoS class identifier; providing a fabric tunnel encapsulation for the packet, wherein the bearer indicator and the QoS class identifier are included within the fabric tunnel encapsulation of the packet; and forwarding the packet within the fabric tunnel encapsulation toward a second switch of the network via a fabric tunnel, wherein the cellular access point is connected to the network via the second switch.

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 facilitate visited network selection by a user equipment (UE) based on slice considerations. In one example, a method may include requesting, by a UE that is roaming among a plurality of visited mobile networks, registration for a network connection associated with a slice type; obtaining, by the UE from home mobile network for the UE, a priority for each of the plurality of visited mobile networks and an indication of one or more slice types provided by each of the plurality of visited mobile networks; selecting, by the UE, a highest priority visited mobile network of the plurality of visited mobile networks that provides the slice type; and establishing, by the UE, the network connection with the highest priority visited mobile network of the plurality of visited mobile networks that provides the slice type.

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: Presented herein are techniques to provide for the ability to optimize the caching of Fast Transition (FT) hierarchical keys based on a derived or statically defined neighbor relationship between wireless wide area (WWA) access network nodes and wireless local area (WLA) access network nodes and also user equipment (UE) mobility triggers in the WWA access network. In one example, a method may include instructing a UE to report detection of a WLA access network and based, at least in part, on obtaining a notification via a WWA access node indicating UE detection of the WLA access network, identifying WLA access nodes that neighbor the WWA access node. The method may further include generating FT key material for the UE and communicating a portion of the FT key material to the WLA access nodes that neighbor the WWA access node to facilitate authenticating the UE to the WLA access network.

Abstract: Presented herein are techniques to facilitate fast roaming between a mobile network operator-public (MNO-public) wireless wide area (WWA) access network and an enterprise private WWA access network. In one example, a method is provided that may include generating, by an authentication node, authentication material for a user equipment (UE) based on the UE being connected to a public WWA access network, wherein the public WWA access network is associated with a mobile network operator, and the authentication node and the UE are associated with an enterprise entity; obtaining, by the authentication node, an indication that the UE is attempting to access a private WWA access network associated with the enterprise entity; and providing, by the authentication node, the authentication material for the UE, wherein the authentication material facilitates connection establishment between the UE and the private WWA access network.

Abstract: In one embodiment, a supervisory device in a network notifies, via an access point of the network, a node as to an ability of the network to support virtual access points. The supervisory device receives, in response to notifying the node, information from the node regarding characteristics of the node. The supervisory device selects, based on the characteristics of the node, a plurality of access points in the network to form a virtual access point with which the node may communicate. The supervisory device configures the plurality of access points to function as the virtual access point, wherein the node communicates with the network via the virtual access point.
