  • Communication system with rapid database synchronization
    Patent number: 6230164
    Abstract: AIN services include multiple SCP pairs, which can be expanded to meet increased demand. The expansion can occur without cessation in services by migrating records between SCP pairs while maintaining redundancy between the pairs. A centralized GTT maintains the GTTs distributed between multiple subsystems in the AIN system. Synchronization between mate SCPs within a pair occurs at high speed as the subscriber database is split into multiple files, each file having a separate synchronization process.
