ABSTRACT:
In a radio communication system, efficient information provision services is obtained where various information is provided to mobile communication terminal devices separately from call services, update information on information to be provided is transmitted from a base station unit, and a mobile communication terminal device receives the update information and then receives the desired information upon confirming that the desired information has been updated. Consequently, due to the ability to easily determine whether or not the information to be provided has been updated, the mobile communication terminal device need not receive all the information or connect to an information service center, but can efficiently use the information provision services.
