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 mobility management entity (MME) controls an enterprise fabric. The MME receives from a mobile device via a cellular network a request to initiate an attach procedure. In response, the MME acquires from the mobile device a unique equipment identifier of the mobile device. The MME generates an enterprise identity for the mobile device based on the unique equipment identifier, and registers the enterprise identity in the enterprise fabric. The MME signals to a user plane function of the cellular network that the mobile device has been registered, to trigger the user plane function to acquire an Internet Protocol (IP) address of the mobile device based on the enterprise identity. The MME receives from the user plane function the acquired IP address. The MME sends to the mobile device, through the cellular network, an attach accept message that includes the acquired IP address for use by the mobile device.

Abstract: Multiple authenticated identities for a single wireless association may be provided. First, an Access Point (AP) may provide an association with a client device. The AP may then establish, on the association, a first authenticated session for the client device based on a first media access control (MAC) address and a first identity. Next, the AP may establish, on same the association, a second authenticated session for the client device based on a second MAC address and a second identity.

Abstract: A control plane (CP) entity is to adaptively reroute user plane traffic of a mobile node (MN) with use of a segment routing (SR) for IPv6. A message indicating an attachment of the MN to the mobile network is received selecting a first user plane (UP) anchor node. A first set of home network prefixes (HNPs) are allocated to the MN. An IP traffic flow using a first HNP prefix is established between the MN and a correspondent node (CN) along a first network path—defined at least in part by the first UP anchor node and an anchor node of the CN. In response to a handover of the MN, a message indicating a subsequent attachment of the MN is received selecting a second UP anchor node. The second UP anchor node is instructed to host the first HNP prefix previously allocated by the first UP anchor node.

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: In one embodiment, a method is performed. A first control plane entity may generate a first seamless bidirectional forwarding detection (S-BFD) control packet. The first S-BFD control packet may include a first discriminator value, a second discriminator value, and a segment routing header. The first discriminator value may be set to a discriminator value associated with a network node of a path comprising a plurality of network nodes. The second discriminator value may be set to a discriminator value associated with the first control plane entity. The segment routing header may be set to an ordered list of values associated with the plurality of network nodes. The values may include at least one of an address or a discriminator value.

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.
