Abstract (en)

[origin: WO03047205A1] An interceptor system (10) for lawful interception in a communications network overcomes the problem of requiring servers of considerable processing capacity by using a traffic interceptor (9) which is a hardware component such as a traffic analyser port (9) which intercepts the data and duplicates it sending one set of data to network filters (21). There is provided a management system which handles legal warrants for interception and through service filters (22) and a database (17) ensures that data which has a target identifier is transmitted onwards and the remainder is destroyed in a secure manner.
