CA 2154803
A method and system for updating a replicated database of a telecommunications network system is disclosed. The database in a network system improves cost, setup time and system availability. A call transport system has switches for forwarding calls from a local telephone station through the call transport system to a destination. A signaling system is operatively connected to the call transport system and includes a primary site databases within the signaling system containing customer records for call routing and other signaling functions and at least one secondary site database containing the customer records of the primary site database. Both primary and secondary site database maintain multiple versions of the same customer record so that queries of a call can use a version number to access the corresponding version of the record in the same database for consistent routing and other signaling information. A customer record is updated in the primary site database and then information concerning the updated database record is transmitted through the signaling network to the secondary site database containing the replicated version of the record. The records are then updated according to the sequence of the version number. The processing of all calls querying the previous version of the primary and secondary site database record are completed before the previous version of the database record is deleted.
