Method for operating a closed subscriber group (CSG) cell for open network access

Abstract

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).

Description

technical field [0001] The invention relates to a method of operating one or more cells in a cellular land mobile network, each cell being identifiable by a transmitted cell identifier, the use of which is / can be restricted to closed subscriber groups by cells with corresponding identifiers , and the cell terminal registers in the corresponding cell to use the land mobile network service only after a positive match with a positive list of authorized cell identifiers stored in the cell terminal. [0002] The invention also relates to a cellular system having a land mobile network with a plurality of cells in which cell terminals can register to use the services of the cellular system, each being identifiable by a transmitted cell identifier Cell, the use is / can be restricted to Closed Subscriber Groups by a cell with a corresponding identifier, and the cell terminal registers in the corresponding cell to use land only after a positive match with the positive list of authorized ...

Problems solved by technology

[0005] The disadvantage is that, since the operator of such a closed subscriber group cell does not have access to a positive list (white list) of authorized cell identifiers stored in terminals of different cells, even if the operator of such a cell wishes to make other It is also not possible for cell terminals to register in the cell and use land mobile network services
