Mobile communication system, operation apparatus and mobile communication method

An operation apparatus configured to provide information to a specific cell radio base station in a mobile communication system including an unmanaged network that is not under the control of a telecommunications carrier, a managed network that is under the control of the telecommunications carrier, and a specific cell radio base station configured to manage a specific cell provided in the unmanaged network, the specific cell radio base station and the security gateway device which are configured to establish a secured connection between the specific cell radio base station and the security gateway device when the specific cell radio base station and the security gateway device are both authenticated as authorized, the operation apparatus comprising:

• a reception unit configured to receive an update request from the specific cell radio base station via the secured connection, the update request including at least identification information of an update target provided in the specific cell radio base station;
• an acquisition unit configured to acquire update information for updating the update target based on the identification information of the update target included in the update request;
• and
• a provision unit configured to provide the update information to the specific cell radio base station via the secured connection.

A mobile communication method applied to a mobile communication system including an unmanaged network that is not under the control of a telecommunications carrier, a managed network that is under the control of the telecommunications carrier, a security gateway device provided in the managed network, an operation apparatus, and a specific cell radio base station configured to manage a specific cell provided in the unmanaged network, the method comprising the steps of:

• establishing, by the specific cell radio base station and the security gateway device, a secured connection between the specific cell radio base station and the security gateway device when the specific cell radio base station and the security gateway device are both authenticated as authorized;
• transmitting an update request from the specific cell radio base station to the security gateway device via the secured connection, the update request including at least identification information of an update target provided in the specific cell radio base station;
• acquiring, by the operation apparatus, update information for updating the update target based on the identification information of the update target included in the update request;
• providing, by the operation apparatus, the update information to the specific cell radio base station via the secured connection;
• and
• updating, by the specific cell radio base station, the update target in the specific cell radio base station based on the update information for updating the update target.
