Abstract: Methods and apparatus for supporting efficient switching of data paths corresponding to a communications session between different non-3GPP access networks, e.g., networks including WiFi access points, using network core functionality are described. A novel registration process in which UE and AMF capability information is exchanged at an early stage in the registration process is described. An initial registration request message from a UE, via a 3GPP or N3GPP access network, includes an indicator as to whether or not the UE supports path switching for MA PDU sessions between N3GPP access paths. This allows, for a UE which supports the path switching, a AMF to be selected and assigned to the UE, which also supports the path switching, thus matching capabilities and eliminating the need for interrupting communications to change AMFs at a later point.

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 a prescribed area or venue, including to users or subscribers of one or more Mobile Network Operators (MNOs). 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., CBSDs) in data communication with a controller, and the core(s) of the MNO network(s). In one variant, the controller dynamically allocates (i) spectrum within the area or venue within CBRS bands, and (ii) MNO “roaming” users or subscribers to CBRS bands (e.g., via extant LTE-TD technology). In one particular implementation, the managed network comprises a Multiple Systems Operator (MSO) network such as a cable or satellite network, and the MSO and MNO coordinate to implement user-specific and/or data-specific policies for the roaming MNO subscribers.

Abstract: Disclosed herein are methods and systems for using out-of-band spectrum for shared spectrum registration and increased link reliability and capacity. A method for customer premise equipment (CPE) attachment and registration in a shared spectrum system includes attaching, by the CPE to a shared spectrum access point, using an out-of-band spectrum, where the out-of-band spectrum is out-of-band with respect to a shared spectrum of the shared spectrum system, registering, by the CPE with a spectrum access system, using the out-of-band spectrum upon successful attachment with the shared spectrum access point, and communicating, by the CPE, using at least the shared spectrum upon successful registration with the spectrum access system.

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.

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., CBSDs 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: A communications system includes a non-MUSIM enhanced PLMN and a MUSIM enhanced PLMN. The MUSIM enhanced PLMN includes a novel Multi-Path (MP) Proxy node. The MP Proxy Node is controlled to switch between two alternative DL data flow paths to facilitate graceful path changeovers. Downlink (DL) data flow toward the non MUSIM enhanced network (e.g., PLMN-A) is based on the interaction between the MUSIM UE and the MUSIM enhanced network (e.g., PLMN-B) together with the novel MultiPath (MP) Proxy node.
