Method for operating one or more cells (10) of a cellular mobile network, each
cell (10) being identifiable by an emitted
cell identifier (CSG_ID) use being limited / limitable to
closed subscriber groups by the
cell (10) having a corresponding identifier (CSG_ID) and the cell terminals (UE1, UE2, UE3) being registered in the respective cell (10) for use of the cellular mobile network services only after a positive matching with a positive
list of authorized cell identifiers (CSG_ID1, CSG_ID2, CSG_ID3) which are stored in the cell terminal (UE1, UE2, UE3), the cell (10) emitting one or more further cell identifiers (CSG_ID2, CSG ID3) in parallel in addition to a first cell identifier (CSG_ID1), and that registration in the cell (10) and use of network services can take place by a first closed subscriber group to which a first group of cell terminals (UE1) belongs, whose respective positive lists contain the first cell identifier (CSG_ID1), and that registration in the cell (10) and use of network services can take place by one or more further open or
closed subscriber groups to which one or more other groups of cell terminals (UE2, UE3) belong whose positive lists contain one or more of said one or more further cell identifiers (CSG ID2, CSG ID3).
