Method for non-standardized dialing service monitoring between networks

Abstract

The invention relates to a method for monitoring internetwork nonstandard dialing services, which is to acquire internetwork incoming and outgoing call records by intercepting monitoring nodes, to perform data analysis on the call records, to examine and verify internetwork call doubtful numbers through an operating center, and to add illegal numbers into an interception number list for interception, so that the method can effectively judge and intercept illegal internetwork communication, and avoid loss of telephone expenses. Moreover, the method has low system modification cost and can be effectively popularized into actual application.

Description

technical field [0001] The invention relates to call monitoring in a mobile communication network. Background technique [0002] With the development of communication technology and services, the competition among operators is becoming more and more fierce, and there are more and more problems in inter-network calls. For example, the callback card service for free calls, frequent harassing calls, free voice calls, irregular ANN calls, and illegal calling, all of which result in the loss of call charges and bring losses to network operators. [0003] Due to the popularity of free mobile calls and the unequal settlement between operators, some fixed network operators took the opportunity to launch an automatic callback card service, adding a set Callback card system 105, the switch automatically completes the call back, and the normal process of establishing a call between the calling party and the called party is modified to user reservation access, the callback system calls...

AI Technical Summary

Problems solved by technology

[0006] 1. Relying on the DTMF number to judge whether the callback card business is not accurate enough, causing misjudgment and affecting normal business;

[0007] 2. It is necessary to modify the signal sent between the networks. Once the equipment fails, the normal business may be affected

[0014] 1. The blacklist interception method can only set individual specific numbers through operators and users, and cannot intelligently judge and intercept general numbers; the timeliness is poor, and it cannot be screened and intercepted in time; it cannot meet the judgment and interception of harassing calls with large call volumes at the carrier level , operators cannot distinguish malicious calls in normal communication

[0015] 2. The scope of application of the password detection method is too small, which will hinder the normal calls between a large number of non-fixed contacts, and will also cause great damage to the convenience of mobile phone users

[0016] 3. Judging harassing calls based on single characteristics such as ringing duration and ringing times is not accurate enough, and many normal calls will also be blocked

In the face of these harassing calls with changing characteristics, it is difficult for existing technologies to accurately identify and intercept them under the premise of ensuring normal user communication

[0018] The disadvantage of the existing monitoring solution for non-standard ANN messages between networks is that it is only applicable to the switching equipment of some manufacturers

[0021] The disadvantage of this existing technology is: in order to effectively restrict illegal incoming calls, it is necessary to upgrade the software on all gateways in the network and make a black and white list, which consumes huge manpower, material resources and time costs, and cannot restrict some special prefixes. Not conducive to future maintenance
