Abstract

An apparatus for providing closed subscriber group access control may include a processor. The processor may be configured to maintain a non-access register including an identifier of a communication cell associated with a closed subscriber group to which a communication device associated with the non-access register does not have access rights, and enable subsequent communication with another communication cell based on the other communication cell not being identified in the non-access register. A corresponding method and computer program product are also provided.
