    • A delivery system includes a delivery apparatus for delivering a common control signal to an area having one or more available communication systems and a terminal apparatus for receiving the common control signal transmitted from the delivery apparatus. The common control signal includes system information required to access the communication systems in the area, and the system information includes multiple control information items. The delivery system causes the delivery apparatus to generate a first common control signal commonly used in one or more areas, to receive a delivery request signal from the terminal apparatus requesting to deliver a certain control information item and to generate a second common control signal including the certain control information item to transmit to the terminal apparatus. Criteria to determine which of the control information items is to be included in the first common control signal are updated in accordance with a statistical tendency of the delivery request signals from the terminal apparatuses.

    • To provide a radio communication control apparatus and a radio communication control method capable of controlling simultaneous transmission and reception so as not to degrade system throughput.A simultaneous transmission and reception controller 106 determines whether the simultaneous transmission and reception using the same frequency are possible, based on radio spectrum environment information of an opposite party of communication and radio spectrum environment information of a self-apparatus. When the simultaneous transmission and reception using the same frequency are determined to be possible, a control signal transmission section 109 transmits instruction information, indicating that the simultaneous transmission and reception are possible, and a transmission parameter thereof, to the above communication terminal. After the transmission parameter is set, a communication section 111 executes simultaneous transmission and reception with the above communication terminal using the same frequency, when the simultaneous transmission and reception using the same frequency are determined to be possible.
