Fraudulent phone call prompting method, service and system

Abstract

The invention discloses a fraudulent phone call prompting method, service and system. The method comprises the steps that a switch receives a mark signal of a called terminal, a calling number related to the conversation of a called number in the mark signal is transmitted to a server; the service counts the number of times for receiving the calling number; if the number of times reaches a preset threshold value, the calling number is recorded in a fraudulent number list; the server periodically collects all calling numbers and called numbers related to the calling numbers in a period from the switch, matches the calling numbers collected each time with the calling numbers marked as fraudulent phone calls in the fraudulent number list and prompts the called numbers related to the matched calling numbers with the information that the calling numbers are the fraudulent phone calls if the matching succeeds. The fraudulent phone call prompting method, service and system are not limited to the types of conversation terminals, meanwhile, the fraudulent numbers can be distinguished at a network side (an operator side), and the fraudulent prompting services can be provided for all the users having conversation records in the switch.

Description

technical field [0001] The invention relates to the field of communications, in particular to a method, server and system for prompting fraudulent calls. Background technique [0002] In recent years, fraudulent text messages, "one ring" phone calls and other means of telecom fraud have occurred every day. With the variety of telecommunications fraud means, the economic losses caused by users will become more and more serious. Telecom fraud is not fraud by telecom operators to users, but fraud by means of telecommunications. Although the means of telecommunications fraud are complex and diverse, most of the current fraud still involves the participation of traditional telecommunications means such as text messages and telephone calls. For fraudulent text messages, telecom operators generally use the filtering technology of sending behavior monitoring and fraudulent content keyword identification to intercept relevant fraudulent text messages; and for fraudulent calls, tele...

AI Technical Summary

Problems solved by technology

If the application is terminated, it will lose its reminder function; but the application will continue to run, which will increase the power consumption of the terminal and lose its convenient functions

[0006] 2) The application must be installed and run on the smart terminal, and the prompt function cannot be realized on the non-smart machine

[0007] 3) The emergence of calling number hiding service and network number changing technology has severely weakened the prompt function of the application, or even lost its effect

[0008] 4) The third-party application server only provides services such as blacklist (such as fraudulent calls) to its authorized users or users using the third-party application, but cannot provide fraud reminder services to all users with call records on the switch

[0009] It is worth mentioning that the current fixed-line phones still belong to the category of non-smart phones, and the anti-fraud methods based on terminal applications are not suitable for fixed-line phones.

At the same time, in view of the corporate responsibility of telecommunications operators, they do not have the right to monitor the content of users' calls, so there is no means of preventing telecommunications fraud for fixed-line telephones
