The invention provides a system and method for collecting information on, and for monitoring a party in a communication network. A monitoring device is adapted to detect the occurrence of identification data generated when a party is starting or receiving a communication, and collects this information in a database. For deciding on monitoring a communication, the database is addressed for comparing the actual identification information with the data stored in the database, and the monitoring of the party is started when the data corresponds to stored identifier data such as the destination identifier of a party to be monitored, the party's identification data or the party's equipment identification data.

Method and system for obtaining identification information on a monitored party in a communication network

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.
