Snooping method based on telecommunication exchanger system

Abstract

The invention relates to a method based on monitoring telegraphy exchange. Wherein, preparing a monitor management module to set objective phone number and notify phone number, an observation module, and a listening-in module in exchange system; when calling phone matching with being monitored number, sending monitor information to management module and triggering listening-in module, transmitting calling control list and notify phone number to listening-in module; listening-in module sends a special calling to being monitored phone; when answering, the listening-in module applies tri-aspect calling resource, obtains exchange network resource of both sides from said list, connects tri-aspect circuit to calling resource, and realizes monitor. This method has high security and reliability, and makes good use of existing exchange function.

Description

technical field [0001] The invention relates to the switch technology in the field of telecommunication, in particular to a monitoring method based on the telecommunication switch system. Background technique [0002] Many communication systems can provide interception services, and interception services can generally only be used by law enforcement agencies. Any interception that is not approved by the legal agency of the country where it is located is considered illegal. The typical application of the monitoring function is generally used by law enforcement agencies when monitoring criminal suspects. By monitoring the phone calls of criminal suspects, they can grasp criminal evidence or hide clues, so that national legal agencies can arrest criminal suspects. At present, many companies have proposed various monitoring methods, such as location-based monitoring methods, wireless network-based monitoring methods, and communication terminal-based monitoring methods. However,...

Problems solved by technology

At present, many companies have proposed various monitoring methods, such as location-based monitoring methods, wireless network-based monitoring methods, and communication terminal-based monitoring methods. However, it also has some disadvantages. For example, the monitoring based on the communication terminal requires the corresponding cooperation of the monitored phone, that is, some transformations, which are almost impossible to realize in some cases.

Using the switching and processing capabilities of the telecommunications switchboard system and the existing telecommunication business functions, by setting the monitored number and the monitored number, the monitoring personnel can monitor the calls of the monitored object, which has not been realized so far.
