Abstract
Directory information is displayed on a mobile handset of a user when a dialed telephone number is a directory-capable number. A directory processor receives the dialed telephone number and checks whether the dialed telephone number appears in a database of directory-capable telephone numbers. A gateway pushes a data message including a data address of a directory server to the mobile handset. The directory server stores directory information for a plurality of call destinations with respective destination identifiers and respective access rules. A client application in the mobile handset responds to the data message. The directory server identifies relevant directory information based on the dialed telephone number and transmits it to the client application via the data call. The client application displays the relevant directory information and the user selects a call destination.
