摘要 |
Various kinds of presentation information specific to an area in a radio-communication system can be transmitted to a one or more specific radio-communication terminals at the same time. A user is able to receive commercial information, for example, from an information provider as presentation information when a user enters a location-registration area. A user terminal transmits a request for a location registration and the location-registration area and a terminal ID are transmitted to the information providing apparatus, which searches a database for a subscriber ID by using the terminal ID as a key and further searches a database for presentation-information ID by using the subscriber ID and the location-registration area information as a pair of keys. The presentation information is then transmitted to the terminal through a USCCH channel and displayed on a display unit of the terminal.
