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.
