    Abstract: Methods and apparatus for providing quasi-licensed intra-cell spectrum reassignment. In one embodiment, the quasi-licensed spectrum utilizes 3.5 GHz CBRS (Citizens Broadband Radio Service) spectrum, and a “seamless” reassignment of wireless spectrum without disruption or loss of continuity to existing data sessions of the CBSD is provided via a pool of temporary RF carriers which act as substitutes for the currently allocated (granted) carriers. The served user devices (e.g., UEs) are instructed by the CBSD to migrate to a new “final” carrier via the substitutes, either directly or via one or more intermediary hops. In one variant, existing 3GPP signaling mechanisms between the UE and CBSD/eNodeB obviates any changes to extant UEs. Communications between the CBSD and its cognizant SAS/DP include new information objects which direct the CBSD to implement the handover functionality. In a further variant, inter-CBSD sector and frequency handovers are provided for using CBRS-plane and 3GPP signaling.

    Abstract: A low-power wide area network supports IP communication between a wireless device and an IP application node. The LPWAN server provides the application node's IP address and a compression/decompression protocol to the device, which applies the protocol (i) to generate a compressed uplink IP header for wireless transmission to LPWAN radio gateway(s), where the compressed IP header is subsequently decompressed to form an uplink IP packet for transmission to the application node and (ii) to decompress a compressed downlink IP header received from a radio gateway, where the compressed IP header was generated from an uncompressed downlink IP header from the IP application node. The device can also segment large uplink IP packets and reassemble large downlink IP packets. In a LoRaWAN network, the join server facilitates arriving at a common compression/decompression protocol and assigns an IP address to the device to enable IP communication with an IP application client.

    Abstract: Methods and systems for multifactor authentication and authorization are described. A method includes receiving captured image data of a person with a badge needing access to a secure area, detecting at least two faces from the captured image data, identifying a first name based on matching a face associated with a live human face with a control face in a database, identifying a second name based on matching on another face associated with the badge with a control face in a database, performing character recognition on text associated with the another face, comparing the second name with the character recognized text, comparing the second name with the first name when the second name matches the character recognized text, checking access rights, checking for at least another person in a proximity of the secure area, and granting access when the person is sole person accessing the secure area.

    Abstract: A network server selects a gateway, from among a plurality of alternative candidate gateways, to use for downlink wireless communication to an end node (EN) based on additional factors in addition to RSSI. Exemplary additional factors include: SNR, gateway loading, message loading, backhaul network loading, device type, application type, application priority, operator preferences, device/application black-lists, white-lists, and red-lists, number of devices, number of transmitting devices in a given time interval, operator rules and priorities. In some embodiments, the network server calculates a composite weighted metric (CWM) for each of the alternative candidate gateways which may be used for downlink, subject to operator policy rules, and selects to use a gateway based on the results, e.g. selects the gateway with the highest CWM.

    Abstract: Various embodiments comprise systems, methods, architectures, mechanisms and apparatus for optimizing the delivery of multicast messages to a set of targeted (receiver) devices via a low power wide area (LPWA) network such as by minimizing a number of gateway devices in a set of gateway devices needed to reach the target devices, by optimizing the use of radio communication resources to minimize costs associated with using metered backhaul network services (e.g., costs associated with using cellular network backhaul services), by maximizing the resiliency, speed, or synchronization of the set of gateway devices, by favoring operator-owned resources, or by achieving other goals consistent with operator policies, preferences and other considerations.

    Abstract: Methods and apparatus for controlling device use of available networks, e.g., cellular and WiFi, are described. End devices report key performance indicator and resource utilization information, e.g., on a per application basis, to a configuration server. The configuration server determines, based on the received information, e.g., using machine learning and/or artificial intelligence, sets of configuration profiles, each configuration profile including one or more set of applications for which an end device should use a particular network. An exemplary configuration profile may identify a first set of applications for which a first network is to be used, e.g., a cellular network such as a P-LTE network, and a second set of applications for which a second network, e.g. a WiFi network, is to be used. The configuration server selects a configuration profile that is best suited for a particular end device and communicates that selected profile to the end device.
