Call side terminal apparatus style detecting method and calling control system

Abstract

This invention relates to a test method for the kind of a calling side terminal device and a call control system applying said method , in which, said method includes: sending a test signal to the calling side terminal device by the PSTN system, judging if the echo signal of said test signal is received, if not, then judging the kind of said terminal device is not the PSTN terminal kind, otherwise, deciding that the kind of the device is the PSTN terminal kind, which realizes the identification to the kind of terminal devices and the identification to the transmission ways in a call link.

Description

technical field [0001] The invention relates to communication link detection technology, in particular to a method for detecting the type of terminal equipment on the calling side. Background technique [0002] As a mature communication system, the Public Switched Telephone Network (PSTN) has the characteristics of large coverage, perfect system construction, and rich service provision; moreover, the interconnection of PSTN communication networks in almost all countries in the world has formed a global An open telecommunication network, therefore, any PSTN terminal user can choose different ways to access the telecommunication network anywhere, enjoy various communication services provided by the telecommunication network, and is oriented to all called terminal users with good network access Provides communication capabilities. [0003] The development of telecommunication technology and the openness of telecommunication networks and services have greatly promoted the devel...

Problems solved by technology

The disadvantage of using the existing technical means to assist the management of the telecommunication network is that: in order to avoid discovery and evade investigation, the calling users who initiate illegal calls often use random disguised calling numbers, so even if the operator receives user complaints or passes signaling detection If an illegal calling number is found, it is impossible to take measures to deal with it; moreover, if an illegal call is detected on the data network or an illegal call is found through user complaints, the call cannot be processed in real time on the PSTN and other telephone networks, so it cannot be done in advance. Prevention, initiative and real-time performance are poor, which makes it difficult to meet the needs of telecom network management

To sum up, there is currently no better technical solution that can actively and effectively identify the type of the calling terminal equipment, so as to distinguish whether the calling terminal equipment is a PSTN user terminal, or a PC calling terminal or a four-wire automatic playback device ; and thus assist in the management of the telecommunications network
