Abstract
An interception system and method for performing a lawful interception in a packet network such as the GPRS or UMTS network is described. The interception system comprises an interception activation monitoring function, an interception activation and deactivation function, an interception data collection function and an interception data destination function. The interception data collection function can be implemented in an existing network node such as a GPRS support node, wherein an interception information is set in the corresponding PDP context, and the collection of the intercepted data is performed in response to the set interception information. Furthermore, the interception data destination function may be arranged in an interception browsing element arranged for browsing the intercepted databased on an external command received from another network element comprising the interception activation and deactivation function. Thereby, browsing and managing of the lawful interception can be separated into different network elements. In summary, a flexible interception system can be provided, which can be easily adapted to individual architectures of packet networks.
