    摘要: A method and system of the present invention updates a replicated database in a foreign telecommunication network system situated in a foreign region and a home country telecommunication network system situated in a home country. The method and system improves call setup time and system availability in a foreign region for customers roaming outside their home country. Customer records are updated in a visitor database contained in a foreign region within the signaling system of foreign telecommunications network. Information concerning the updated database record is transmitted from the visitor database through the signaling network of a home country to a home database which contains the replicated version of the visitor database record in the foreign region. A field is added to the database record corresponding to a version number of the database record so as to identify the record referenced by queries of calls in progress. The home database record at the home country is changed to reflect changes in the visitor database at the foreign region by using the version number sequence while maintaining at all database sites the older version of the database record for query access until after completing the processing of all previous call querying the database record.
