Method and system for intercepting fraud phones in real time during calling

Abstract

Disclosed are a method and a system for intercepting fraud phones in real time during calling. The method includes that when a call made by a calling user is triggered to a service control point (SCP) through a calling mobile switching center (MSC), the SCP instructs the calling MSC to perform call proceeding, so that the calling user and the called user are in voice communication; meanwhile, a fraud prevention platform acquires messages received by the SCP in real time, whether the calling number contains in an intercept number table or not is judged when the call, made by the calling user, received by the SCP is recognized, if so, then a called visitor location register (VLR) is instructed to remove the voice channel between the calling user and the called user after the calling user and the called user are in voice communication, otherwise, the process is ended. The method and the system belong to the technical field of network communications and can realize real-time interception to the fraud phones without any adjustment of existing networks.

Description

technical field [0001] The invention relates to a method and system for intercepting fraudulent calls in real time during a call, and belongs to the technical field of network communication. Background technique [0002] With the popularization of mobile phones, phone scams emerge in endlessly. Although the relevant government departments have issued reminders to the society and various news media have reported frequently, however, a large number of users are still being cheated every day, and the economic losses are increasing year by year. [0003] How to effectively intercept fraudulent calls from the network side, some related solutions have also been proposed at present. For example: patent application CN 200610103230.6 (application name: a method for using mobile intelligent network to realize user incoming call filtering service, applicant: ZTE Corporation, application date: 2006‐07‐14) discloses a mobile intelligent The method for realizing the user incoming call f...

Problems solved by technology

However, this technical solution needs to increase the call interception process on the basis of the existing communication network and business architecture, first judge the call to be intercepted, and then transfer the call to the relevant network element to continue to complete the corresponding call based on the judgment result. business process, resulting in a large amount of changes and adjustments on the live network, and the cost of anti-fraud is also very high
