Mobile communication locating and tracking system and locating and tracking method thereof based on voiceprint recognition

Abstract

The invention discloses a mobile communication locating and tracking system and a locating and tracking method thereof based on voiceprint recognition. The mobile communication locating and tracking system comprises a control module (Q) which is connected with a voiceprint recognition module (P), a video monitoring subsystem (M), a mobile switching center (MSC) and a gateway mobile locating center (GMLC) of a mobile communication network respectively; and the voiceprint recognition module (P) is further connected with media gateway of the mobile switching center (MSC). Whether criminal suspects change phone numbers or not, the system can locate and track the criminal suspects, a video monitoring subsystem is utilized to compare and confirm videos again on the basis of voiceprint comparison, so that the criminal suspects can be arrested rapidly and accurately.
