An interception method and system for performing a lawful interception in a packet network such as a GPRS network is described, wherein a subscriber identity is allocated to an interceptor, such that the interceptor is treated as a mobile station. Thus, the interception traffic is processed as usual data traffic which can be charged using normal charging procedures and which can be intercepted using the normal lawful interception methods. Accordingly, no additional functions are required for charging and intercepting an interception.
