Abstract

An apparatus for querying a central service dials telephone numbers to establish contact with the central service, and accesses services housed in the central service. The geographical location of the apparatus is stored in a tie unit and sent to the apparatus upon request. The apparatus forwards this information to the central service that then provides information about facilities (e.g., restaurants, sports venues, theaters, etc.) at that location.
