Abstract
Abstract A method and apparatus for enabling a user to request location information from a mobile station telephone unit is disclosed. A user enters a request for location information concerning a particular type of business. The request is processed by a module within the mobile station and transmitted to the home location register for the mobile station via the base station and mobile switching center serving the mobile station. The home location register determines the location area and cell identity for the mobile station and transmits this information plus the original request to a relational database. The relational database determines the identity of businesses located either within or near the location area and/or cell identity of the mobile station. This information and the addresses of the identified business is transmitted back to the mobile station for review by the user.
