Abstract: Systems, methods, and computer program products relating to anchoring a wireless device to a wireless controller. A type of a network device is identified based on data included in a network message received at a first wireless local area network (LAN) controller (WLC). It is determined, based on the identified type, that the network device should be anchored to a pre-determined anchor WLC. An anchor request message is transmitted from the first WLC to the pre-determined anchor WLC. A network traffic tunnel is established between the network device and the pre-determined anchor WLC such that network traffic from the network device can be controlled by the pre-determined anchor WLC.

Abstract: In one embodiment, a networking device in a network forms a Wi-Fi association with a node on a first wireless channel. The networking device preforms a passive scan of Wi-Fi Neighbor Awareness Network (NAN) channels and receives a NAN discovery beacon from a NAN via a particular one of the NAN channels during the passive scan. The networking device generates a NAN cluster discovery attribute for the NAN based on the received NAN discovery beacon, and sends the NAN discovery attribute to the node via the first wireless channel, wherein the node uses the NAN discovery attribute to associate with the NAN.

Abstract: Techniques and mechanisms for processing broadcast data traffic for a plurality of user equipments (UEs) of a virtual network group are described herein. In one illustrative example, a user plane function may receive a broadcast packet from one of the UEs or a data network; perform a packet detection rule (PDR) lookup for the broadcast packet, for identifying a PDR and a forwarding action rule (FAR) associated with it; process the broadcast packet in accordance with an apply action of the FAR, for creating a tunnel management message having a payload which encapsulates the broadcast packet; and send the tunnel management message to a base station which is configured to perform unicast data delivery of the broadcast packet to each one of at least some of the plurality of UEs of the virtual network group. The user plane function may configured for use in a public cloud for 5G-as-a-Service (5GaaS).

Abstract: A radio access network (RAN) entity (e.g. an eNodeB) may be configured to facilitate multicast communication in a local private Third Generation Partnership Project (3GPP) network. The RAN entity may receive a user data packet tunneled in an IP message via one of a plurality of downlink tunnels. The RAN entity may select, from a plurality of stored mappings, one of a plurality of multicast group identifiers that is mapped to an identified one of a plurality of downlink tunnel endpoint identifiers that matches a downlink tunnel endpoint identifier from a tunnel header of the IP message, as well as one of a plurality of sets of UE identifiers that is mapped to the selected multicast group identifier. The RAN may send, for each one of the UE identifiers in the selected set of UE identifiers, the user data packet for transmission to a UE associated with the UE identifier.

Abstract: A network function is configured to initiate a bulk session cleanup with a single release request. The network function detects a configuration change to a wireless network system that affects multiple user sessions for multiple user devices. The network function generates a single bulk session release request identifying the affected user sessions and provides the single bulk session release request to at least one other network function responsible for the user sessions.

Abstract: In one illustrative example, a user plane function (UPF) may detect initial traffic for an application for a user equipment (UE) for which no current dedicated Quality of Service (QoS) flow is established. In response, the UPF may send, to a control plane function, a message which indicates a request for creating a dedicated QoS Flow for traffic for the application for the UE. The message may include flow metadata and an application identifier obtained in detecting the initial traffic. A QoS Flow may then be created for the traffic based on a selected QoS policy associated with the application identifier. Subsequently, the UPF may determine that a measured time period of traffic inactivity for the QoS Flow is outside a limit set by a threshold. Based on the determining, the UPF may send, to the control plane function, a message which indicates a request for deleting the QoS Flow.

Abstract: Techniques are described herein for providing cellular access of a user-defined network. In one example, a user plane function of a cellular network obtains, from a control plane function of the cellular network, an indication that a first user equipment is attempting to connect to a user-defined network via the cellular network. The user plane function joins a multicast group configured to include a second user equipment connected to the user-defined network via a wireless local area network. The user plane function obtains a multicast packet that is transmitted between the first user equipment and the second user equipment and that is addressed to the multicast group, and converts the multicast packet to a unicast packet.
