Embodiment Construction
[0024] The embodiment of the invention provides a technical solution for realizing legal interception of a wide area communication network. Because the wide area communication network is a communication network that covers a wide area and covers many types of equipment. The wide-area communication network can be divided into different localized communication networks according to the geographical scope to which it belongs.
[0025] In the embodiment of the present invention, in order to realize the seamless geographical coverage of legal interception, the legal interception center is divided into two different levels: local interception center and advanced interception center. These two monitoring centers can be connected in a network to achieve geographical coverage. A large first-level monitoring center can be set up in the whole country, with several second-level monitoring centers, and then several local monitoring centers to form a hierarchical network structure, as show...

The utility model relates to a WAN legal monitoring method according to the following steps: (1) in the entire monitoring area, one or more local monitoring centers and previous monitoring centers are established by each listening bureau to form a laminated network structure which covers entire monitoring area; (2) each to-be-monitored bureau is connected with local monitoring centers or previous monitoring centers through monitoring interfaces, network monitoring interfaces configured with interface protocols are arranged between local monitoring centers and previous monitoring centers, so that all monitoring centers are connected together through the network monitoring interfaces so as to transmit information mutually; (3) the monitoring centers perform the control to the to-be-monitored users and transfers monitoring directions to the corresponding to-be-monitored bureau; (4) when the to-be-monitored bureau judges that the to-be-monitored user occurs various controlled operations, the communication contents of the to-be-monitored user are reported to each monitoring center. The utility model has an advantage that full network monitoring can be realized.
Description
technical field [0001] The present invention relates to communication technology, in particular to information security technology in communication technology, and more specifically, to a method for legally intercepting a wide area communication network. Background technique [0002] At present, with the needs of the international political situation, especially the anti-terrorism situation, various countries and regions have developed and legalized the monitoring of communication networks from a legal perspective, which has also become legal monitoring. In lawful interception, the interception device uses a specific interception technology interface to intercept and analyze the communication content related to the intercepted communication network. At present, the monitoring device and the monitored network can only monitor the communication network in a local area, that is, a monitoring device can only monitor users in a local communication network in a certain country and...
