Legal monitoring system for mobile communication network

The invention discloses a legal monitoring system for a mobile communication network. The legal monitoring system is characterized by comprising an access transmission subsystem, an information acquisition subsystem and an information processing subsystem, wherein the access transmission subsystem is used for acquiring data from an interface A of the mobile communication network and sending the data to the information acquisition subsystem; the information acquisition subsystem is used for acquiring and resolving signaling data and voice data, comprehensively processing signaling and trans-storing a short message and the voice data; and the information processing subsystem is used for storing the data and analyzing and processing the information. The legal monitoring system for the mobile communication network is simple in structure, can effectively monitor the voice data and the signaling data of all users and effectively process and store the monitored data and has wide monitoring range and high monitoring
