Problems solved by technology

It can be seen that the current single-point monitoring monitoring method has the following disadvantages: multiple monitoring centers LEMF are independent of each other, there is no networking function, and the monitoring device is a single device with a single service and small capacity, which cannot realize inter-device monitoring. Networking; effective monitoring and sharing of monitoring information cannot be achieved when the country has a large territory and many telecommunications users

Embodiment Construction

[0043] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings.

[0044] The present invention connects a plurality of listening centers (LEMF) and a plurality of listening switching devices (LIAF) through an IP network, and like this, LEMF and LIAF are all similar to IP telephone gateway equipment; The circuit domain voice data received by the monitoring trigger side is converted into IP data and sent to the LEMF for monitoring.

[0045] Referring to FIG. 2, FIG. 2 is a schematic diagram of a monitoring network system in a preferred embodiment of the present invention. The monitoring network side of the monitoring network system includes: one or more monitoring centers 200, one or more monitoring switching devices 210; the monitoring triggering side includes monitoring triggering devices: MSC or fixed network sw...

Abstract

This invention discloses an audio monitor network system, it includes one or multi monitor center, one or multi monitor transfer facility, the above monitor transfer facility connects to the mobile services switching center and HardLink exchanger through the public telephone switching network, the above monitor center communicates with the transfer facility through IP network. The invention also discloses a monitor method includes following steps: 1) the monitor center sends multi monitoring orders to multi monitor transfer facility; 2) the monitor transfer facility retransfers the monitoring orders to 9 monitoring triggering devices; 3) the monitoring triggering devices labels the controlled target; 4) when capturing the circuit domain audio data of the controlled target, the monitoring transfer facility switches the above circuit domain audio data into IP protocol data and sends it to one or more monitor center. The invention can meet the need for monitoring in the whole web.

Description

technical field [0001] The invention relates to monitoring technology, in particular to a monitoring network system and a monitoring method thereof. Background technique [0002] Legal interception is required by national laws. Operators provide monitoring trigger interfaces, and equipment manufacturers provide solutions for monitoring network-side voice and event transmission. According to legal authorization, national security agencies will require network operators or service providers to provide specific target monitoring results to specific monitoring authorities or enforcement agencies (LEA). [0003] At present, lawful interception is usually implemented according to the separation of the circuit domain and the packet domain stipulated in the ETSI protocol. There are various types of interception devices and networking methods between devices. Some monitoring methods can realize the interception and monitoring of voice and various services, but they all monitor a sin...
