Abstract
A service center has a plurality of controlled areas. When the service center provides service information through a radio communication network, the service center first broadcasts toward all the areas with outline items of the information with corresponding key codes attached thereto. Users each receive the outline items of the information with a user's terminal and determine as required whether a detail item of the information should be had immediately (an urgent one) or can be had later (a regular one). The results of the determination are reported to the service center, which immediately provides the urgent detail items of the information for the respective users who made requests for having those detail items. The service center broadcasts regular detail items of the information with attached corresponding key codes other than the requested urgent ones of the information toward the terminals which requested the regular detail items of the information at a predetermined time. Each terminal has stored a key code attached to the outline item of the information which the terminal requested in a regular manner, and receives only a necessary detail item of the information.
