Information delivery system and information delivery method four

摘要

An information delivery system and information delivery method are provided that avoid any increase in radio traffic and meet the requirements of users by delivering information to a user terminal only when available radio resources are present. An available radio resources determination section determines whether or not available radio resources are present in each zone. When an information delivery section acquires information about presence of available radio resources in zones from the available radio resources determination section, it delivers information stored in an information database to user terminals located in the zones in which the available radio resources have been detected. Thus it is able to deliver information to a user terminal without causing any increase in the radio traffic.
