A radio terminal connection may be handed over from a serving base station associated with a serving cell to a closed subscriber group (CSG) cell served by a CSG base station in which only radio terminals belonging to the CSG are permitted to access and receive service from the CSG cell. Radio terminals in the serving cell are generally informed not to report to the serving base station signal quality measurements of signals transmitted by CSG base stations. But if a radio terminal in the serving cell is authorized to access and receive service from the CSG cell, then that radio terminal is instructed to report to the serving base station signal quality measurements of signals transmitted by the CSG base station. Based on that report, the connection may be handed over to the CSG base station. A central node provides a CSG authorization list identifying CSG authorized radio terminals to the serving base station when a listed CSG cell is a neighboring cell which the radio terminal is authorized to access.
