Abstract
A wireless cellular and personal communication system has a remote personal database storage device that interrogates the personal database information contained within a subscriber's mobile terminal or handset during the initial phase of an outgoing or incoming wireless telephone call to ascertain if there have been changes made to the personal database. The interrogation is an undirected act on the part of the subscriber and is a service provided by the telecommunication service provider. If changes have been made in the personal database in the subscriber's mobile terminal, then the subscriber's entries in the remote personal database storage device are appropriately updated.
