    Abstract: A method for Internet of Things (IoT) network security includes collecting information for each network device (device), determining a minimum viable resource allocation for each device based on the information, which defines the minimum resources needed by each device to engage the IoT network and handle data, and for each device, distributing minimum viable resource allocations and rules, determining monitoring sets, monitoring using the monitoring set, collecting updated information based partially on the monitoring set, analyzing the updated information to determine trends and insights relative to the devices and the IoT network, updating the monitoring set, minimum viable resource allocation, and rules based on the analyzed updated information, checking compliance with a current minimum viable resource allocation and rules, identifying devices having violations, and performing same on a continuous as it and automatic basis. The method establishes and maintains a chain of custody for data traversing through multiple network segments.

    Abstract: Methods and apparatus for providing quasi-licensed spectrum access within an area or venue. In one embodiment, the quasi-licensed spectrum utilizes 3.5 GHz CBRS (Citizens Broadband Radio Service) spectrum allocated by a Federal or commercial SAS (Spectrum Access System) to a managed content delivery network that includes one or more wireless access nodes (e.g., CSDs and APs) in data communication with a controller. In one variant, the controller dynamically allocates (i) spectrum within the area or venue within CBRS bands, and (ii) MSO users or subscribers to CBRS bands or WLAN (e.g., public ISM) bands in to manage interference between the coexisting networks, and maximize user experience. In another variant, the controller cooperates with a provisioning server to implement a client device application program or “app” on MSO user or subscriber client devices which enables inter-RAT access.

    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 radio access network (RAN) for a wireless communication network transmits, to user equipment (UE), information about NPN services provided by a non-public network (NPN) supported by the wireless network, where the UE is not subscribed to the NPN. In some embodiments, the NPN service information is periodically broadcasted to the UE; in other embodiments, the information is transmitted in response to receiving a request from the UE. In response to receiving the NPN service information, the UE transmits and the RAN receives an on-boarding request from the UE to on-board the UE to the NPN, which the RAN forwards to an on-boarding network (OBN) of the wireless network. In response, the RAN receives NPN credentials for the UE from the OBN, which the RAN forwards to the UE, which uses the NPN credentials to register to the NPN, thereby enabling the non-subscribing UE to subscribe to the NPN.

    Abstract: Methods and apparatus for providing quasi-licensed spectrum allocation among two or more entities within a prescribed coverage or operational area. In one embodiment, the quasi-licensed spectrum utilizes 3.5 GHz CBRS (Citizens Broadband Radio Service) spectrum allocated between two or more Federal or commercial SASs (Spectrum Access Systems), for use by various service provider entities such as a managed content delivery network that includes one or more wireless access nodes (e.g., CBSDs). In one variant, each of two or more SAS entities generate both proposed allocations for themselves and other participating SAS entities with respect to available GAA spectrum, and differences between the proposed allocations are reconciled and condensed using a dynamic, iterative process to converge on a final allocation which fits the available GAA spectrum and which equitably distributes the spectrum between the participating SAS entities.
