System and method for implementing call authentication gateway

Abstract

The invention relates to a system and a method for realizing a call authentication gateway. The system consists of a plurality of signaling message detection and processing modules MPM which are connected with related No. 7 signaling links, and a local service management server LSMS, wherein the MPMs detect and process passed signaling messages and transmit related messages to the LSMS; the LSMS generates a black list with telephone numbers or number segments required for control according to a call authentication requirement, and synchronizes the black list in various MPMs; and the MPMs realize control processing of subsequent call according to the black list and service rules. The system and the method can be independently implemented without modifying the prior network equipment, avoid the problems of equipment upgrade and data modification of the prior net elements, and are flexible to control services and convenient to deploy. The system provides an effective means for telecom operators to implement call barring service and black and white list service.

Description

technical field [0001] The invention relates to a communication control and information security technology, in particular to a system and method for realizing a call authentication gateway. Specifically, on the premise of not needing to modify the existing network equipment, call authentication is implemented independently, so as to achieve the purpose of standardizing the calling number and restricting illegal calls in real time. Background technique [0002] In order to ensure smooth communication between networks, it is necessary to standardize the calling number and restrict unreasonable calls in real time. Unreasonable calls include illegal calls for the purpose of fraud, harassment, and billing evasion, and calls that should not occur in the Internet by using the caller authentication loophole of the Internet gateway GW. [0003] To control unreasonable calls, generally configure the black and white list function on the GW to control such calls. This method requires...

Problems solved by technology

This method requires that multiple GWs in the network must have this function, but due to the limitation of the black and white list capacity of early equipment, or the GW does not have this function, and due to various combinations of unreasonable calling and called number ranges, these GWs cannot Timely adapt to the demand of restricting unreasonable calls, and upgrading multi-vendor GW brings large investment, high risk, and complicated implementation and operation
