  • System and method for controlling data access
    Patent number: 6460081
    Abstract: A system and method for controlling data access by a user device on a network utilizes a subscriber database cataloging the device identity and the corresponding dynamic address. The system includes an interworking function device operative to receive a call from the user device. The user device has a corresponding dynamic address. The interworking function device sends a message to the subscriber database indicating the device identity and the corresponding dynamic address. The sent information is cataloged at the subscriber database to allow the server, when the server receives the corresponding dynamic address, to retrieve the device identity from the subscriber database and to control data access over the network based on the device identity.
