If the UE reports to the MNO base station, that it has detected signals from base stations, e.g. CBSDs, in its MVNO, the MNO base station applies one or more rules included in a stored Service Profile Identifier, corresponding to the UE, the applying of the one or more rules causes the MNO base station to disconnect or deny service to the UE. Alternatively, when it is determined that the UE did not detect a signal from a base station, e.g. a CBSD, in its MVNO, then the MNO base station provides communications service to the UE. ## Claims ### Claim 1 A communications method, the method comprising: determining, at a first Mobile Network Operator (MNO) base station, from RF signal information received from a first user equipment (UE) which receives services from a first Mobile Virtual Network Operator (MVNO) network, whether a signal from a base station in the first MVNO network was detected by the first UE;
