According to the present invention a method for implementing connection access authorization between a first entity and a second entity in a communication system comprising at least one closed user group is disclosed. The method comprises the steps of storing a table (DB3) of special identifications for an entity belonging to a closed user group, receiving a connection request, a) checking (12) whether the connection is within a closed user group, b) checking (13) whether all connections across the border of the closed user groups of both the first and the second entities are allowed, c) checking (14) whether the first entity belongs to the table (DB3) of special identifications for the second entity, and giving connection access (15) if at least one of the conditions a, b and c is true. By this method, a rejection of a connection request is overridden in case an entity having a special identification, e.g., a subscriber having a special number, is called. The invention also proposes a device for carrying out the method.
