Abstract
A technique for generating a correlation number for use in lawful interception of telecommunications traffic includes handling one of either a “PDP (Packet Data Protocol) context activation” or “Start of intercept(ion) with PDP context active” event and generating a unique PDP-ID (PDP Context Identifier) in response thereto. An MCC (Mobile Country Code) and an MNC (Mobile Network Code) of a network operator is identified, as is a DF (Delivery Function)-ID of a DF. The MCC and MNC are combined to generate an Operator-ID. The generated PDP-ID and the generated Operator-ID and the DF-ID are combined to generate the correlation number.
