Methods and systems for extracting mobile communication terminal identifiers from mobile terminals carried on individuals. The disclosed techniques refer to communication terminals that communicate over both a cellular network and a Wireless Local Area Network (WLAN). An interrogation device intercepts the communication of such a communication terminal at a defined location and at a defined time. The interrogation device extracts from the intercepted communication two types of identifiers - a cellular identifier that identifies the terminal in the cellular network, and a WLAN identifier that identifies the terminal in the WLAN. A correlation system correlates the cellular and WLAN identifiers, and output the correlation for later use. |
