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: 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: Paging for converged enterprise private Long-term Evolution (LTE) radio service and Wi-Fi access deployments may be provided. First, a notification in response to a User Equipment (UE) device being determined to be in an idle state may be received at a Wireless Local Area Network (WLAN) controller. A Citizens Broadband Radio Service (CBRS) Access Point (AP) to page in order to place the UE in a connected state may then be determined. Next, a paging request may be sent to the determined CBRS AP.

Abstract: In one embodiment, a method is performed. An interworking module of a wireless local access network (LAN) controller may receive a non-access stratum (NAS) message from an access point (AP) device using a control and provisioning of wireless access protocols (CAPWAP) tunnel. The NAS message may be translated to a WiFi service layer message. The WiFi service layer message may be sent to a wireless control plane module of the wireless LAN controller.

Abstract: Systems, methods, and computer-readable media are provided for modifying a network service of a requesting network member. A request, received from the requesting member, can include an identification of a sponsoring network member for a requested network service modification. A group can be generated and associated with the requesting member and with the sponsoring member. The group may also include a group policy referencing the requested network service modification. The sponsoring member can be provided with an activation key for activating the network service modification and a first network policy can be applied to the requesting member and a second network policy can be applied to the sponsoring member.

Abstract: An example method is provided in one example embodiment and may include receiving an indication of a radio access technology (RAT) change for a user equipment (UE); determining availability of a preferred RAT type for a policy related rule associated with the UE, wherein the policy related rule includes, at least in part, the preferred RAT type for one or more service data flows for the UE; and configuring the one or more service data flows for the UE based, at least in part, on a change in availability of the preferred RAT type following the RAT change. In at least one case, the method can include routing downlink packets to the UE using the one or more service data flows for the preferred RAT type if the preferred RAT type is available.
