Signal cascading media redirection fraud call prevention access system and method

Abstract

The invention discloses a signal cascading media redirection fraud call prevention access system. The system comprises media carrying equipment, information protection equipment and soft exchange equipment, wherein the media carrying equipment communicates with a whole-network media gateway; the information protection equipment is used for detecting signals and processing and forwarding bidirectional media streams; the soft exchange equipment is used for continuing the signals and / or the media streams; the media carrying equipment is in a communication connection with the soft exchange equipment; the information protection equipment accesses side ends of the media carrying equipment and the soft exchange equipment respectively; if the information protection equipment finds a fraud call suspicious call during detection of signals flowing inwards through the media carrying equipment, bidirectional media stream paths of a calling party and a called party are redirected to pass through the information protection equipment, and bidirectional media streams are processed and forwarded through the information protection equipment; and if the fraud call suspicious call is not found, the media stream path is not changed. The invention also provides a method corresponding to the system.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to an anti-fraud phone access system and method in which signaling is concatenated with media redirection. Background technique [0002] Current telecommunication fraud activities are rampant day by day, and the broad masses of the people suffer greatly from it. Various related manufacturers have put forward their own solutions to prevent telecom fraud crimes, which have effectively prevented telecom fraud crimes to a certain extent. In terms of how to prevent information protection equipment from connecting to the telecommunication network, most manufacturers currently use the following three methods: Method 1, using parallel connection to collect telecommunication network signaling, and find out from the call records generated by the signaling through data analysis Fraudulent calls; method 2, using the intelligent network method, and the operator transfers all traffic to a d...

Problems solved by technology

[0003] However, with the development of communication technology and the evolution of telecommunication networks, the current telecommunication network has developed from a traditional hierarchical network architecture based on circuit switching to a flat network architecture based on packet switching (soft switching), so the above three This method reveals its shortcomings in practical application

[0004] The deficiencies of these three methods are mainly reflected in the following aspects: the first method of prevention can only be analyzed after the event, which cannot meet the real-time requirements; Greatly increased the network risk; using signaling media to prevent fraudulent calls in series, under the layered network structure in the circuit switching era, can perfectly solve the problem of fraudulent call prevention, but in the packet switching era, in the fully flat The use of full serial connection under the network architecture will bring huge investment and construction scale, and the cost performance problem is very prominent
