Abstract: The presently claimed disclosure is directed to methods that may be implemented at a computer. Methods and systems consistent with the present disclosure may include extending protocols associated with authenticating client (i.e. supplicant) devices and with authorizing those supplicant devices to access a wireless network. These methods may include sending data relating to the failure of an authentication and/or an authorization process to a supplicant device attempting to access a wireless network. Methods discussed within may include securely sending failure codes or reasons to a supplicant device that identify why an authentication or authorization process failed. These methods may include sending messages between a supplicant device, an authenticator device, and an authentication and authorization server. After a first failure, the supplicant device may be able to access the wireless network after a reason or code of that failure has been reported to the supplicant device.

Abstract: Systems, methods, and computer-readable media for radio resource management in a Citizens Broadband Radio Service (CBRS) network include one or more CBRS devices (CBSDs) which can obtain a group type associated with the CBSDs and their associated Radio Environment Map (REM) reports of one or more frequency channels of the CBRS network. The group type and the REM reports may be provided to a Self-Organizing Network (SON) manager of the CBRS network, where the SON manager may determine and provide to the CBSDs, one or more of a channel utilization information, transmission power, or mobility load management information for the CBSD, based on the group type and the REM reports.

Abstract: Presented herein are techniques to facilitate OpenRoaming integration into a Wireless Roaming Intermediary Exchange (WRIX) data-clearing and financial-settlement architecture. In one example, a method is provided that may include querying, by an application endpoint, a Domain Name System (DNS) server to determine support for a service for a domain; and obtaining, by the application endpoint from the DNS server, an explicit indication that one of: the service is not supported for the domain; or the service is proprietary and is supported for the domain.

Abstract: Techniques are described for integrating cellular access within an enterprise fabric. In one example, a method includes obtaining, by a cellular termination function via a cellular access point, a request from a client for data plane connectivity via a network, wherein the cellular access point is registered within the network and is in communication with a first switch of the network; obtaining, by the cellular termination function, cellular policy information and enterprise policy information for the client; obtaining, by the cellular termination function, an Internet Protocol (IP) address for the client; and establishing data plane connectivity for the client with the network via the cellular access point, the first switch of the network, and a second switch of the network based, at least in part, on the IP address for the client, wherein the second switch connects the network with one or more data networks.

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 various implementations, a method includes receiving a request to establish an end-to-end encrypted session between a device in an enterprise network and an external entity that is outside the enterprise network. In some implementations, the end-to-end encrypted session allows encrypted packets to be transmitted between the device and the external entity. In various implementations, the method includes determining whether the request satisfies an enterprise security criterion for establishing the end-to-end encryption session. In various implementations, the method includes in response to determining that the request satisfies the enterprise security criterion, triggering the establishment of the end-to-end encrypted session between the device in the enterprise network and the external entity that is outside the enterprise entity.

Abstract: Roaming Consortium Identifier (RCOI)-based handling of identity requirements may be provided. First, an access device may advertise an identifier. The identifier may identify a roaming federation and an identity type used by a service provider in order to provide service by the access device. Next, a request to associate with the access device may be received from a user device. The request may be compliant with the identity type advertised in the identifier. The user device may then be associated with the access device in response to receiving the request.

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 devices are disclosed for providing a quality of service between nodes. A service provider can receive, from a first node of a customer network to an ingress node of a service provider network, packets bound for a second node on the customer network that is remote from the first node. The packets are mapped to a network segment according to a traffic type based on an identifier associated with the packets that identifies the traffic type of the packets. The packets are sent via their mapped network segment to an egress node with connectivity to the second node of the customer network according to a quality of service associated with the traffic type identified by the identifier.
