Abstract: A network slice controller obtains health information of an active network slice provided by a first vendor and health information of a set of backup network slices provided by a second vendor. The network slice controller evaluates, using a set of policies corresponding to management of the active network slice, the health information of the active network slice to determine whether the active network slice has failed. As a result of the failure of the active network slice, the network slice controller identifies one or more backup network slices of the set of backup network slices to serve as new active network slices. The network slice controller activates these one or more backup network slices to serve as the new active network slices for the network.

Abstract: In one illustrative example, a user plane (UP) entity for use in a mobile network may receive a data packet from a user equipment (UE) operative to communicate in one or more sessions via a serving base station (BS) (e.g. eNB or gNB) of the mobile network. The UP entity may detect, in a header (e.g. SRH) of the data packet, an identifier indicating a new serving BS or session of the UE. The identifier may be UE- or BS-added data (e.g. iOAM data) that is inserted in the header by the UE or BS. In response, the UP entity may cause a message to be sent to an analytics function (e.g. a NWDAF) to perform analytics for session or flow migration for the UE.

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: 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: Techniques are described to provide a network location service for a user equipment (UE) when the UE is not served by a 3GPP radio; thereby enabling radio resource selection by the UE for Autonomous PC5 based communications. In one example, a method includes receiving, by a mobility element of a network, an attach request from a UE, wherein the attach request indicates an attach type associated with a network location service. The method may further include communicating, based on the attach type being associated with the network location service, an attach accept to the UE to trigger a location request for the UE, wherein the attach accept is communicated to the UE without the mobility element authenticating the UE; and communicating location information to the UE based on the location request.

Abstract: In one implementation, the method comprises, in response to obtaining a request to associate an electronic device with the one or more WLAN termination nodes: generating, between a base station and a networking device, a control link based on a first identifier associated with the base station; generating, between the networking device and a first WLAN termination node, a control link based on a second identifier that corresponds to a pseudonym for the base station; and associating the first and second identifiers in a control table. The method further comprises: instantiating, between the base station and the networking device, a first data tunnel associated with a first tunneling protocol; instantiating, between the networking device and the first WLAN termination node, a second data tunnel associated with a second tunneling protocol; and associating the first and second data tunnels.

Abstract: In one embodiment, a method is performed. A device may receive a registration request from a user equipment (UE) device associated with a category. The device may receive a registration response from an access and mobility function (AMF). The registration response may comprise a group identifier associated with the category. The device may select resources from a resource pool based on the group identifier. The resource pool may be dedicated for use for emergency communications. The device may allocate the selected resources to the UE device.

Abstract: A controller of a macro wireless network provisions a user device for access to local private networks based on the cell that the user device uses to attach to the macro wireless network. The controller obtains information on private networks operating within a coverage area of the macro wireless network. The controller associates a particular cell of the macro wireless network with one or more private networks operating within the particular cell. The controller detects a user device in the particular cell and provisions the user device with access to the one or more private networks.

Abstract: A control plane of a network, including radios of a radio access network controlled by the control plane and user plane functions controlled by the control plane, establishes first and second protocol data unit (PDU) connections each to handle the same flows of traffic for ultra-reliable low latency communications (URLLC) from user equipment to a data network through first and second source radios, respectively. Due to mobility of the user equipment, the control plane relocates the flows from the first and second source radios to first and second target radios, respectively. To relocate the flows, the control plane receives from the first target radio a notification that identifies flows that cannot be activated on the first target radio. In response to the notification, the control plane commands the first target radio to prioritize the flows that cannot be activated above remaining ones of the flows.
