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.

Abstract: An ISP 10 provides enhanced features compatible with non-AIN switches to allow service providers to provide customers with features such as voice prompting, DTMF number collection, fax on demand and similar features. In one embodiment, the ISP can also be configured as an IP. Enhanced features can be accomplished using the ISP, such as advanced routing of long distance calls based on ANI, authorization codes, type of call, time of day, origination of call and destination of call.

Abstract: A distributed redundant database architecture (10) primarily for storing a plurality of wireless service subscriber files (84, 86) is provided. The database architecture (10) include a first set of processors (44 46, 48) each having a shared memory (72, 74, 76), where the processors (44, 46, 48) are divided into processor groups (38, 40, 42). A memory storage device (80, 82) is coupled to each processor group (38, 40, 42) in a multi-initiator mode so that each memory storage device (80, 82) is accessible by the processors (44, 46, 48) in its respective processor group (38, 40, 42). The plurality of subscriber files (84, 86) are assigned to the processor groups (38, 40, 42) and further assigned to the processors (44, 46, 48) in each processor group (38, 40, 42) to achieve a substantially even distribution.
