  • Method and apparatus for updating distributed databases in a telecommunications network
    Patent number: 5974429
    Abstract: A method and apparatus for updating user data stored on databases distributed throughout a teleconmmunications network is described. A central database server stores a master copy of the user data from which a transaction journal may be created. The transaction journal includes every change in user data entered at the central database server during provisioning sessions. The remote nodes of the network contain databases which ideally store user data which is consistent with the user data records in the central database server. To achieve this the new transaction journal entries are propagated at regular intervals to the remote nodes. During a transition period, the central database server and the remote nodes are updated with new software.
