Abstract: Techniques are described to provide open access in a neutral host environment. In one example, a method includes obtaining, by a mobility management node of a neutral host network, a network connectivity request from a user equipment, wherein the network connectivity request comprises an indication of a preferred service provider to which the user equipment is to be connected; determining, by the mobility management node, that the preferred service provider provides non-subscription-based network connectivity for the neutral host network; based on determining that the preferred service provider provides non-subscription-based network connectivity for the neutral host network, establishing secure communications for the user equipment, wherein the secure communications are established for the user equipment without authenticating an identity of user equipment; and providing network connectivity between the user equipment and the preferred service provider upon establishing the secure communications.

Abstract: A default pre-shared key is provided from a first device to a second device. The first device is configured to control network access to a network. A first authentication request is obtained at the first device from a third device. The first authentication request includes data indicative of the second device. A first response to the first authentication request is provided from the first device to the third device. The first response includes the default pre-shared key. A second authentication request containing a private pre-shared key and the data indicative of the second device is obtained at the first device from the third device. Stored data at the first device is updated in response to the second authentication request with the private pre-shared key and the data indicative of the second device to provision the first device to provide network access to the network to the second device.

Abstract: A network management center includes a Dynamic Host Configuration Protocol (DHCP) server. The network management center obtains from an identity server, client information indicating authentication of a client device in a wireless network that is connected to a network fabric. The network management center obtains from an edge node in the network fabric an Internet Protocol (IP) address request for the client device. The IP address request including a fabric domain identifier associated with the edge node. The network management center allocates an IP address for the client device based on the client information obtained from the identity server and the fabric domain identifier contained in the IP address request obtained from the edge node. The network management center provides to the edge node an Identifier Locator Addressing (ILA) address based on the IP address.

Abstract: Dynamic application QoS profile provisioning may be provided. First, an access point may send a profile to a client device. The profile may comprise a plurality of application identifiers and a plurality policies corresponding to the plurality of application identifiers. Each of the plurality of application identifiers may respectively correspond to a plurality of applications. Next, the client device may receive the profile. Then the client device may select, from the received profile, a first policy from the plurality policies in the profile. The first policy may correspond to a first application identifier in the plurality of application identifiers. The first application identifier may correspond to a first application within the plurality of applications. The first application may be on the client device. The first application on the client device may then create a network flow from the client device to the access point based on the selected first policy.

Abstract: Systems, methods, and computer-readable media are provided for an efficient roaming management method using a single association identifier token for associating with different access points. In one aspect of the present disclosure, a network controller includes memory having computer-readable instructions stored therein and one or more processors. The one or more processors are configured to execute the computer-readable instructions to receive a request from an endpoint to connect to a first access point; generate association identification token (e.g., PMK and PMKID) for the endpoint to connect to the first access point; and distribute the association identification token to a second access point prior to the endpoint attempting to connect to the second access point, the association identification token being used by the second access point to validate a subsequent request by the endpoint to connect to the second access point.

Abstract: In one embodiment, a device identifies a path of travel of a mobile system. The device subdivides the path of travel into a plurality of zones. The device generates time-slotted channel hopping schedules for the plurality of zones, each time-slotted channel hopping schedule having an associated zone among the plurality of zones. The device causes the mobile system to communicate wirelessly with networking infrastructure located along the path of travel, in accordance with a particular one of the time-slotted channel hopping schedules while the mobile system is located in its associated zone.

Abstract: In one embodiment, a mobile system scans wireless channels for any upcoming access points using a dedicated monitor radio of the mobile system. The mobile system identifies a particular wireless channel in use by an upcoming access point. The mobile system notifies a second radio of the mobile system of the particular wireless channel. The mobile system performs a handoff between a current access point and the upcoming access point in part by switching the second radio of the mobile system to the particular wireless channel of the upcoming access point.

Abstract: A wireless client device communicates, to an access point over a secure channel, a mapping of a dynamic device address to a stable device address. By communicating the mapping, the access point is able to determine that packets received from two different device addresses originate from a common device. The access point is then able to maintain an association between the originating device and other network resources assigned or allocated to the originating device, such as IP addresses or infrastructure station address, which is used to identify the originating device to other devices outside the network in some embodiments.

Abstract: In one example, a Network Policy Function (NPF) obtains a first identifier for a User Equipment (UE) based on communications between the UE and a first access network of a system, and an Internet Protocol (IP) address used by the UE to communicate over the first access network. The NPF obtains a second identifier for the UE based on communications between the UE and a second access network of the system. The NPF determines that the UE used the IP address to communicate over the first access network of the system based on a correlation between the first identifier for the UE and the second identifier for the UE. The NPF provides the IP address to the UE, and the UE uses the IP address to communicate over the second access network.
