METHOD AND SYSTEM FOR SYNCHRONIZATION OF TWO DATABASES IN A LAWFUL INTERCEPTION NETWORK BY COMPARING CHECKSUM VALUES

摘要

The present invention relates to methods and Validity securing arrangement and embodiments thereof for effectively securing validity of a target database in a node in a Lawful Interception Network. Said target database is intended to be identical to a source target database. The arrangement comprises a processing means being adapted to send a request for a target database checksum to the node comprising the target database, to receive a response comprising the target database checksum from the requested node, to compare the received target database checksum to a source target database checksum determined for the corresponding source target database, and to send an order to start an audit and synchronisation process if the two compared checksums differ.

1. A method for securing validity of a target database in a node of a Lawful Interception Network, said target database intended to be identical to a source target database:
sending a request for a target database checksum to the node comprising the target database; receiving a response comprising the target database checksum from the requested node; comparing the received target database checksum to a source target database checksum determined for the corresponding source target database; and sending an order to start an audit and synchronisation process if the two compared checksums differ.
