Abstract
A personalized caller ID service is provided. A subscriber to the service who is calling his own telephone line from a remote location may enter a personal identification number (PIN) after dialing the subscriber's telephone number. A database within the telephone network stores a text message along with the PIN, where the text message is preferably composed by the subscriber at the time of enrollment in the personalized caller ID server. When the PIN is entered, the text message is retrieved from the database and transmitted to the subscriber's caller ID equipment during call termination for display on that equipment. The invention may be embodied in an Advanced Intelligent Network (AIN), wherein a termination attempt trigger (TAT) is provisioned on the subscriber's line. Upon actuation of the trigger, the service control point within the AIN instructs the service switching point that services the caller's line to prompt the caller for a PIN and collect the PIN digits.
