Claim:
A process for operating one or more cells of a land mobile network, each cell being identifiable by an emitted cell identifier, use of the cells being limited or limitable to closed subscriber groups such that, when one of the cells is limited to a closed subscriber group, this one cell has a first corresponding identifier that indicates the limited use and a cell terminal can only check into the one limited cell for use of the land mobile network services when the first identifier of the one limited cell matches an identifier in a positive list of authorized cell identifiers stored in the cell terminal, wherein the cell parallel emits one or more further cell identifiers in addition to the first cell identifier, and checking-in in the cell and use of network services takes place by a first cell terminal of a first group of cell terminals that belong to a first closed subscriber group when the respective positive list in the first cell terminal contains the first cell identifier, and checking-in in the cell and use of network services can take place by another cell terminal of another group of cell terminals that belong to a further open or closed subscriber group when the positive lists of the other cell terminal contains the further cell identifiers.
