Call controlling system and call controlling method

Abstract

This invention relates to a call control system and a call control method, in which, said system includes: a test subsystem including a signaling test unit and a real time test unit, in which, the signaling test unit tests the signaling signals of the signaling link of an access system and triggers the real time test unit to test the calls with the call characters, a real time test unit tests the echo signal character of the call link to get the test result with the character meeting the test strategy and a call control strategy process unit gets the result tested by the subsystem to finish the call control, which combines the test to call link signaling with voice channel phone signals to realize the monitor to record phones without providing call source address.

Description

Technical field [0001] The invention relates to call detection technology, in particular to a system for detecting calls via a telecommunication network and then performing call control, and a call control method. Background technique [0002] In the Internet, many browsers already have the function of real-time detection and filtering of advertisements; in the email receiving and dispatching system, corresponding options can also be set to detect spam and reject it. [0003] As a mature communication system, the Public Switched Telephone Network (PSTN) has the characteristics of large coverage, complete system construction, and rich service provision. In addition, the interconnection of PSTN communication networks in almost all countries in the world has formed a global Open telecommunications network, therefore, any PSTN terminal user can choose different ways to access the telecommunications network at any place, enjoy various communication services provided by the telecommuni...

Problems solved by technology

[0006] Since there is no technical solution for effective call detection at present, the above method is generally adopted. The defect of this method is that it adopts a passive detection method, that is, it relies on user complaints or known calling numbers to perform call detection. However, with the development of technology, illegal calls usually do not have real and effective calling numbers, so the success rate of existing detection methods is low; and, for newly generated illegal calls, existing methods cannot timely In addition, it is impossible to quickly identify and detect calls in ongoing calls, so the real-time and initiative of existing methods are poor
