Abstract

A hybrid interception system that comprises both a passive interception subsystem and an active interception subsystem that operate jointly to intercept communication of a target wireless terminal. A passive interception system receives the communication without transmitting to the mobile communication terminal. An active interception system intercepts the communication by initiating temporary bidirectional communication with the terminal. The target terminal may be initially detected by the passive interception subsystem, while in other embodiments it is detected by the active interception subsystem. The subsystem that detects the target terminal triggers the other subsystem, so that the target terminal is effectively intercepted jointly by both subsystems. The outputs of both the passive and the active interception are analyzed jointly, stored in a joint data structure, and/or presented jointly to an operator. This joint analysis and presentation increases the quality and intelligence value of the intercepted information.
