1. A mobile communication system including:
- mobile terminals;
a closed subscriber group (CSG) cell operating in a closed access mode in which a specified one of the mobile terminals can access the CSG cell; and
a non-CSG cell operating in an open access mode in which an unspecified one of the mobile terminals can access the non-CSG cell, whereina CSG indicator indicates whether a cell is a CSG cell or not is broadcasted,the mobile communication system further includes a hybrid cell operating in a hybrid access mode which shows an operation form of the CSG cell and supports both the closed access mode and the open access mode at the same time,the hybrid cell sets the CSG indicator to indicate that the cell is not the CSG cell, andthe mobile terminals receive the CSG indicator.

Abstract
In a communication system including a specified subscriber cell which allows a specific mobile terminal to use the specified subscriber cell, and an unspecified user cell which an unspecified mobile terminal can use, in which each mobile terminal receives cell identification information assigned to each communication cell and makes a cell selection, identification information for identifying the CSG cell operating in an open access mode is included in the cell identification information.

5. A cell used in a mobile communication system including mobile terminals, the cell comprising:
-
a CSG cell operating in a closed access mode in which a specified one of the mobile terminals can access the CSG cell; and a non-CSG cell operating in an open access mode in which an unspecified one of the mobile terminals can access the non-CSG cell, wherein a CSG indicator indicates whether a cell is a CSG cell or not is broadcasted, and in a hybrid access mode which shows an operation form of the CSG cell and supports both the closed access mode and the open access mode at the same time, the cell sets the CSG indicator to indicate that the cell is not the CSG cell. - View Dependent Claims (6)

7. A mobile terminal used in a mobile communication system including
a CSG cell operating in a closed access mode in which a specified mobile terminal can access the CSG cell, and a non-CSG cell operating in an open access mode in which an unspecified mobile terminal can access the non-CSG cell, wherein a CSG indicator indicates whether a cell is a CSG cell or not is broadcasted, the mobile terminal comprising: a receiver that receives the CSG indicator set by a hybrid cell operating in a hybrid access mode which shows an operation form of the CSG cell and supports both the closed access mode and the open access mode at the same time. - View Dependent Claims (8)

9. A mobile terminal used in a mobile communication system including
a CSG cell operating in a closed access mode in which a specified mobile terminal can access the CSG cell, and a non-CSG cell operating in an open access mode in which an unspecified mobile terminal can access the non-CSG cell, the mobile terminal comprising: -
a receiver that receives a CSG-ID, which is a specific identification number, broadcasted by a hybrid cell operating in a hybrid access mode which shows an operation form of the CSG cell and supports both the closed access mode and the open access mode at the same time; and a controller that selects a cell having a desired CSG-ID.
