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 computing device determines a plurality of probability-based trajectories a mobile device could traverse through a plurality of access point (AP) cells within a given area depending on an entry point of the mobile device into the given area. A predictive dwell time may also be associated to each AP cell based on how long a mobile device is expected to remain within the respective AP cell. Based on i) current locations of mobile devices, ii) the plurality of probability-based trajectories a mobile device could traverse through the plurality of AP cells, and iii) the predictive dwell time of each AP cell, the computing device can compute a probability of mobile device density surpassing a potential flash crowd threshold within each AP cell at any given future time. In response, the computing device may then perform one or more mitigation actions.

Abstract: An example method is provided in one example embodiment and may include receiving a request from a user equipment (UE) to access a wireless access network, wherein the UE is currently accessing one or more other wireless networks; determining by a Policy and Charging Rules Function (PCRF) whether a subscriber associated with the UE is authorized to access the wireless access network based, at least in part, on a profile for the subscriber; and communicating one of a wireless access rejection and a wireless access acceptance to the UE based on the determination. In some instances, the determining can include recovering the profile for the subscriber associated with the UE from a Subscriber Profile Repository (SPR) using an International Mobile Subscriber Identity (IMSI) for the subscriber.

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: An access point for a private network onboards a wireless device obtaining a connection request from the wireless device and detecting a standardized identifier that indicates the wireless device is unprovisioned for access to the private network. The access point disables an authentication protocol for granting access to the wireless device on the private network and limits access of the private network by the wireless device to accessing a provisioning server. The access point provides a connection response to the wireless device that indicates limited access to the private network.
