Abstract: A cellular base station and/or associated equipment will detect the presence of nearby public safety communication and, in response, will automatically change the base station's antenna beam pattern to be directed to a predefined safe direction, so as to quickly minimize the likelihood of the base station producing harmful interference to the public safety communication. Further, after thus quickly working to minimize the likelihood of such interference, the base station and/or associated equipment could then more specifically determine a direction from which the public safety communication is arriving and could further adjust the base station's antenna beam pattern to be directed away from the determined direction.

Abstract: A method and system for a base station (BS) configured for sharing among a plurality of public land mobile networks (PLMNs), and for providing open radio access and/or closed subscriber group (CSG) radio access for user equipment devices (UEs) served. The BS may make a determination of which PLMNs have enabled CSG and which have not, and may transmit a request to a core network of each PLMN to set up an interface connection with each. Based on the determination, the request may either include information for configuring CSG radio access, or information for configuring only open radio access. For each PLMN having CSG enabled, the interface connection may be established for CSG radio access for UEs associated with PLMNs having CSG enabled. For each PLMN not having CSG enabled, the interface connection may be established for only open radio access for UEs associated with PLMNs without CSG enabled.
