Abstract: Techniques are described for providing wireless network connectivity using a distributed mobility management functionality. In one example, each of a plurality of on-premise access points co-locate a mobility management functionality and a packet routing and forwarding functionality. Each of the plurality of on-premise access points obtain, from user equipment, a request to wirelessly connect to the on-premise access point. Each of the plurality of on-premise access points provide the user equipment with wireless network connectivity using the co-located mobility management functionality and the packet routing and forwarding functionality.

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: In one embodiment, a process determines how often client devices roam from a given access point (AP) to each particular neighbor AP of a plurality of neighbor APs of the given AP, and correspondingly determines a roaming distance from the given AP to each particular neighbor AP, the roaming distance being shorter for neighbor APs roamed to more often, and longer for neighbor APs roamed to less often, within a given interval. Successful but temporary roams to the plurality of neighbor APs may also be detected and removed from consideration in the roaming distance to that particular neighbor AP. The process then generates a proximity list of one or more of the neighboring APs having the shortest roaming distances, and feeds the proximity list to the given AP to cause the given AP to provide the proximity list to client devices for optimized client roaming.

Abstract: Techniques are provided for a network device to receive a first notification message from a first wireless network operating via a first radio frequency protocol, where the notification message indicates a presence of a mobile device within a radio frequency coverage area of a first wireless access point in the first wireless network. A connection message is transmitted from the network device to the mobile device, where the connection message comprises information configured to initiate a connection of the mobile device to a second wireless network operating via a second radio frequency protocol when a radio frequency coverage area of a second wireless access point in the second wireless network is known to overlap the radio frequency coverage area of the first wireless access point in the first wireless network. The connection message may initiate mobile device connections or transfers between, e.g., macrocell, femtocell, and Wi-Fi networks, among other networks.

Abstract: A wireless device provides a connection request to an access point for a private network. The connection request includes a standardized identifier that corresponds to an unprovisioned wireless device. The connection response from the access point indicates that the wireless device is provided access to the private network only for communications with a provisioning server. The wireless device provides a provisioning request to the provisioning server and obtains a provisioning response that include an operational profile to enable access to the private network when the wireless device is configured according to the operational profile.
