Displaying business directory information on a mobile handset

摘要

The graphical display capability and the digital data communication capability of wireless mobile handsets are used to present a customized directory of a called enterprise on the display screen of the mobile handset to allow the caller to identify their desired call destination by name. A directory database stores directory information for each call destination of the enterprise. An incoming call to an enterprise IVR unit causes a directory manager to generate a request for user data which is forwarded to the mobile handset via a gateway. The mobile handset opens a data connection and forwards the user data to the directory manager. The directory manager evaluates at least one access rule in response to the user data to select relevant directory information from the directory database, and the directory manager forwards the relevant directory information to the mobile handset for display. Then the user of the mobile handset selects a call destination based on the displayed directory information.
