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: 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 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: Methods and apparatus for supporting 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. This allows a communications session in which a UE is involved as an end point to be switched between two different WiFi access networks and/or a WiFi access network and a 3GPP access network, e.g., cellular access network, without the communications session being terminated while service is provided to the UE by a Public Land Mobile Network (PLMN) with which it is registered. A UE can switch between multiple WiFi networks while maintaining a communications session supported by network core functionality even though the session may be switched between different non-3GPP networks while the session is ongoing.

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: 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 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.
