Mobile communication system, radio base station, mobility management node, and mobile station

A radio base station, comprising:

• a management unit configured to manage a first list which is a list of mobile stations allowed to connect to a cell under the radio base station as a primary cell, and additionally a second list which is a list of mobile stations allowed to configure the cell as a secondary cell;
• a reception unit configured to acquire, from a mobile station in the cell, at least one of first indication information indicating whether or not the mobile station is a member of the first list and second indication information indicating whether or not the mobile station is a member of the second list, wherein the mobile station is capable of performing a carrier aggregation using the primary cell and the secondary cell;
• and
• a control unit configured to determine whether or not the mobile station is allowed to connect to the cell as a primary cell and determine whether or not the mobile station is allowed to configure the cell as a secondary cell by referring to the management unit based on the at least one of the first indication information and the second indication information.

A mobility management node, comprising:

• a management unit configured to manage at least one of a first list which is a list of mobile stations allowed to connect to a cell under the mobility management node as a primary cell and a second list which is a list of mobile stations allowed to configure the cell as a secondary cell;
• a reception unit configured to acquire, from a mobile station in the cell, at least one of first indication information indicating whether or not the mobile station is a member of the first list and second indication information indicating whether or not the mobile station is a member of the second list, wherein the mobile station is capable of performing a carrier aggregation using the primary cell and the secondary cell;
• and
• a control unit configured to determine whether or not the mobile station is allowed to connect to the cell as a primary cell and determine whether or not the mobile station is allowed to configure the cell as a secondary cell by referring to the management unit based on the at least one of the first indication information and the second indication information.

A mobile station, comprising:

• a transmission unit configured to notify a network of at least one of first indication information indicating whether or not the mobile station is a member of a first list and second indication information indicating whether or not the mobile station is a member of a second list, wherein
• the first list is a list of mobile stations allowed to connect to a cell under the network as a primary cell,
• the second list is a list of mobile stations allowed to configure the cell as a secondary cell, and
• the mobile station is capable of performing a carrier aggregation using the primary cell and the secondary cell.
