  • Distributed subscriber data management in wireless networks from a central perspective
    Patent number: 6091952
    Abstract: A system and method for increasing capacity of a cellular system by reducing call overhead processing and transmission congestion previously required in updating a subscriber's mobile station data position as the subscriber moves among locations within a geographic area served by a network service provider is presented. A predetermined N number of copies of mobile station subscriber data is distributed among multiple Visiting Location Registers (VLRs) within the area served by a cellular system. Unlike previous systems, when mobile stations traverse location boundaries, the current VLR corresponding to the current location does not need to update the subscriber data if that data has not changed since the subscriber was last in that location.
    Type: Grant
    Filed: May 29, 1997
    Date of Patent: July 18, 2000
    Assignee: Nortel Networks Corporation
