MOBILE COMMUNICATION SYSTEM
First Claim
1. A mobile communication system including mobile terminals each for transmitting and receiving data by using an OFDM (Orthogonal Frequency Division Multiplexing) method as a downlink access method, and by using an SC-FDMA (Single Career Frequency Division Multiple Access) method as an uplink access method, a base station disposed in a specified subscriber cell which is a communication cell which allows a specific one of said mobile terminals or a specific subscriber to use said specified subscriber cell, and a base station disposed in an unspecified user cell which is a communication cell which an unspecified one of said mobile terminals or an unspecified user can use, and a base station control apparatus for managing a desired tracking area where said mobile terminals are located via said base stations, and for performing a paging process on said mobile terminals, each of said mobile terminals receiving cell identification information (PCI) assigned to each of said communication cells, for identifying each of said communication cells from said base stations, and selecting a cell with which each of said mobile terminals communicates, whereinsaid specified subscriber cell can simultaneously employ a first operation mode in which said specified subscriber cell allows said specific mobile terminal or said specific subscriber to use said specified subscriber cell, and a second operation mode in which said specified subscriber cell allows said unspecified mobile terminal or said unspecified user to use said specified subscriber cell, and said cell identification information includes identification information for identifying said specified subscriber cell operating in said second operation mode.

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.

4. A mobile communication system including mobile terminals each for transmitting and receiving data by using an OFDM (Orthogonal Frequency Division Multiplexing) method as a downlink access method, and by using an SC-FDMA (Single Career Frequency Division Multiple Access) method as an uplink access method, a base station disposed in a specified subscriber cell which is a communication cell which allows a specific one of said mobile terminals or a specific subscriber to use said specified subscriber cell, and a base station disposed in an unspecified user cell which is a communication cell which an unspecified one of said mobile terminal or an unspecified user can use, and a base station control apparatus for managing a desired tracking area where said mobile terminals are located via said base stations, each of said mobile terminals receiving cell identification information (PCI) for identifying each of said communication cells from said base stations, and selecting a cell with which each of said mobile terminals communicates, and each of said mobile terminal accessing said specified subscriber cell by using access allowance information which is issued when allowed to use said specified subscriber cell, wherein
a tracking area of said specified subscriber cell which can simultaneously employ a first operation mode in which said specified subscriber cell allows said specific mobile terminal or said specific subscriber to use said specified subscriber cell, and a second operation mode in which said specified subscriber cell allows said unspecified mobile terminal or said unspecified user to use said specified subscriber cell is managed as a tracking area of said specified subscriber cell operating in said first operation mode, and each of said mobile terminals determines whether or not to access said specified subscriber cell on a basis of a tracking area identifier included in said access allowance information, and mode information showing in which one of said first and second operation modes said specified subscriber cell operates.

5. A mobile communication system including mobile terminals each for transmitting and receiving data by using an OFDM (Orthogonal Frequency Division Multiplexing) method as a downlink access method, and by using an SC-FDMA (Single Career Frequency Division Multiple Access) method as an uplink access method, a base station disposed in a specified subscriber cell which is a communication cell which allows a specific one of said mobile terminals or a specific subscriber to use said specified subscriber cell, and a base station disposed in an unspecified user cell which is a communication cell which an unspecified one of said mobile terminal or an unspecified user can use, and a base station control apparatus for managing a desired tracking area where said mobile terminals are located via said base stations, and for performing a paging process on said mobile terminals, each of said mobile terminals receiving cell identification information (PCI) assigned to each of said communication cells, for identifying each of said communication cells from said base stations, and selecting a cell with which each of said mobile terminals communicates, wherein
said specified subscriber cell can employ a first operation mode in which said specified subscriber cell allows said specific mobile terminal or said specific subscriber to use said specified subscriber cell, a second operation mode in which said specified subscriber cell allows said unspecified mobile terminal or said unspecified user to use said specified subscriber cell, and a third operation mode in which said specified subscriber cell processes simultaneously said first operation mode and said second operation mode, and said cell identification information includes identification information for identifying said specified subscriber cell operating in said third operation mode.
