GEOGRAPHICAL DATABASE FOR RADIO SYSTEM

摘要

A geographical database connected to a mobile radio network (10) contains information about consumer services within the network (10) and about a plurality of geographic areas into which the service area of the network (10) is divided. When a mobile station (19) seeks to obtain information from the database by entering one or more search key words, the network (10) determines the current geographic location of the mobile station (19) within the network (10). Both the search keys and the mobile station's current location are used to search the database and return to the mobile station (19) information about available consumer services in different zones made up of geographic areas near its current location. The input and output from the database may be voice or text.
