Embodiment Construction

[0034] In the softswitch system, the monitoring device is responsible for all business activities and communications of the controlled target (that is, the softswitch device terminal being deployed, such as: fixed-line incoming equipment, H.323 network equipment, SIP network equipment, and IP protocol terminal equipment). Content and other information are monitored. Functionally, it mainly consists of four parts: call control function, data collection function, submission function and content reproduction function. These four functions are realized by the softswitch control device, data acquisition device (access gateway or monitoring gateway), submission gateway device (DF) and police information center (LIC). The network structure of the softswitch monitoring system is as follows: figure 1 As shown, the softswitch control device, the access gateway, the monitoring gateway (LI GW) and the submitting gateway are connected to each other via an IP network, and the submitting ga...

Abstract

This invention discloses a call control and service listening method for software exchange listening including the following steps: a warning information center sets up connection with software exchange control devices and controls the users of the devices by listening instructions to correct or inquire attributes of related users. If the user is a controlled one, the device reports to the information center the call state information of the controlled user after starting the calling and instructs a data collection device to collect the call communication content information and forward it to the information center to relicate it, after the call is finished, the devices release the occupied resources and stop listening the call.

Description

technical field [0001] The present invention relates to soft switch system terminal user monitoring, in particular to the call control and service monitoring method of the soft switch system in the next generation network (NextGeneration Network, NGN). Background technique [0002] The interface of the softswitch system to realize the monitoring function is called the police interface. The main purpose of the police interface is to maintain national security and combat various forms of crime. With the increasingly fierce anti-terrorist struggle on a global scale, governments of various countries are paying more and more attention to legal interception, and have formulated corresponding laws and regulations. Support for legal interception has gradually become one of the access requirements for network equipment. [0003] The police interface means that the state authority monitors specific communication users through special equipment in accordance with statutory procedures. ...
