Title:
SYNCHRONIZATION OF DATABASE DATA
Document Type and Number:
WIPO Patent Application WO2002086758
Kind Code:
A8
Abstract:
A method of arranging synchronization of databases, the method comprising the steps of establishing a transport layer connection for synchronization between a first and a second device which synchronize databases. During initialization of synchronization a first update identifier, which is stored at least in the first device and describes the latest synchronization event the devices have performed in the databases, and a second update identifier, which is defined by the first device and describes the present synchronization, are transmitted from the first device to the second device. The second update identifier is stored in the first and the second device. The contents of the first update identifiers stored in the devices are updated in the first and the second device if synchronization has been performed and after this said transport layer connection has been ended substantially properly.
