Patent ID: 7162248

Claim:
A radio control apparatus that performs communication with a mobile station using a first frequency band area and a second frequency band area in a mobile communication system, the mobile station performing control to stop radio wave transmission while maintaining a communication line when there is no data to be transmitted, the radio control apparatus comprising: a mobile station information storage unit that stores a communication pattern of the mobile station; a reception unit that receives a request for data transmission to the mobile station; a radio wave communication detecting unit that determines whether radio wave transmission and reception are being performed with the mobile station in a communication operation using the first frequency band area; a time decision unit that determines a transmission time for data transmission in a communication operation using the second frequency band area based on communication pattern information as to the mobile station that is a data transmission destination designated by the request for data transmission, the communication pattern information being stored in the mobile station information storage unit; and a transmission unit that transmits the requested data to the mobile station as the data transmission destination within the transmission time determined by the time decision unit, when the radio wave communication detecting unit determines that radio wave transmission and reception are not being performed in the communication operation using the first frequency band area, said first frequency band area at least partially overlapping said second frequency band area.
