System and method for monitoring network

Abstract

The monitoring network system includes one or more monitoring center, one or more monitoring switchover equipment. The said monitoring switchover equipment through public exchange telephone network and Internet is connected to mobile exchange center or exchanger in fixed network, and the said monitoring center through IP network carries out communication with monitoring switchover equipment. The monitoring method including (1) monitoring center registers multiple monitoring switchover equipment; (2) monitoring switchover equipment forwards monitoring command to multiple monitoring trigger equipment; (3) monitoring trigger equipment labels targets to be controlled; (4) when voice data in circuit domain of controlled targets being captured, monitoring switchover equipment converts voice data to stream media and stores it, and the stream media is sent to one or more monitoring center. Features are: capable of monitoring whole network in larger range and multiple users.

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...

AI Technical Summary

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

[0013] In addition, the above-mentioned monitoring method also has the following disadvantages: first, there are problems such as difficulty in implementing LIAF or LEMF in monitoring networking and high cost; second, LEMF equipment is complicated and expensive: on the LEMF side, it is necessary to A series of tasks such as processing, playing and storing the monitoring information sent over require LEMF to provide powerful hardware and an upgradable complex software system; thirdly, in order to ensure the safe transmission of the monitoring voice, it is necessary Establish a dedicated exchange network for voice transmission between LIAF and LEMF; fourth, it is difficult to monitor new services of operators: if operators monitor a new service, upgrade LEMF according to the existing solution, because The number of LEMF is relatively large, and the upgrade cost is relatively high
