AUTOMATIC ADDRESS BOOK UPDATE SYSTEM

The automatic address book update system which automates the data collection and maintenance tasks for computerized address book systems. The automatic address book update system is architected to automatically update the data contained therein, by automatically populating the address entries of a subscriber's computerized address book system. This is accomplished as part of the origination/receipt of a telephone call by the subscriber, where the Local Exchange Carrier (LEC) maintains a customer database (identifying the name, address, telephone number) of their local customers and can also retrieve this information from other Local Exchange Carriers on a long distance call. Upon the initiation of a call connection between the subscriber and a calling/called party, the Local Exchange Carrier identifies the address book update service authorization for the subscriber, retrieves the calling/called party's customer database information, and transmits this information to the subscriber's address books system to populate an entry therein under the name of the calling/called party.
