DETAILED DESCRIPTION The subject disclosure describes, among other things, illustrative embodiments for providing continuity of service between CBRS and one or more licensed cellular spectrums managed by a same or different service providers. In one or more embodiments, the system and method employs or otherwise facilitates a tunneled Open Radio Access Network (ORAN) that connects a communication device(s) to a network core (e.g., a 5G, 6G, NG core), which can include utilizing CBRS coverage that interfaces or otherwise operates in conjunction with the tunneling. In one or more embodiments, a tunneled ORAN can deliver services to a location with limited or no wireless coverage utilizing CBRS coverage that is available in the particular location. In one or more embodiments, a tunneled ORAN can deliver services to a premises with limited or no wireless coverage such as utilizing CBRS coverage that is available in the particular location. In one or more embodiments, a tunneled ORAN can deliver services via a fiber optic or other hardwire connection to a location (e.g., a premises, business, etc.) with limited or no wireless coverage such as utilizing CBRS coverage that is available in the particular location. In one or more embodiments, the tunneled ORAN can be requested, managed, and/or facilitated by a device(s) (e.g., a MOCN device, a wireless router, a residential gateway, a mobile phone, a desktop computer, a laptop computer) that can access a different RAT or different spectrum, including accessing CBRS coverage in order to deliver services to a location with limited or no wireless coverage. In one or more embodiments, one, some or all of the communications/packets/data/information exchanged via the tunneled ORAN can be flagged or otherwise marked to indicate (e.g., to the network core) that a tunneled ORAN is being employed and/or to indicate actual or approximate location information for the particular communication device utilizing the tunneled ORAN. In one or more embodiments, a method and system is provided for call and coverage continuity even if Spectrum Access System (SAS) prevents or prohibits (either temporarily or permanently) a local private wireless device/network from using CBRS (e.g., a higher priority customer requires use of the band such as U.S. Navy radar operators). In one or more embodiments, a default or back-up service is employed based on a private network having macro-coverage from a wireless carrier(s) that uses commercial/licensed spectrum. In one or more embodiments, the method and system can address instances where commercial/licensed radio spectrum is not available, becomes unavailable, and/or has limited availability (e.g., traffic over a threshold and/or available resources under a threshold). CBRS is a
