Embodiment Construction

[0020] The new call-back service is different from the traditional "call-back card" service. It applies VoIP technology to mobile phones, connects to the call-back platform through the GPRS network, and then the call-back platform initiates a call to the calling party and the called party. connect. In this scenario, traditional authentication techniques are powerless.

[0021] The invention finds out the signaling behavior characteristics conforming to the call-back service through correlation analysis of the GPRS network access record and the A-interface call record, and can solve the identification of the new call-back service that cannot be solved by the prior art.

[0022] The appearance characteristics of the new callback service are: the call list of the called number is normal, but the corresponding call list cannot be found by the calling party, all call records are called, and the calling number is a long-distance fixed-line number in other places.

[0023] The callb...

Abstract

The invention provides a method for identifying novel malicious soon back imprest call by using a signaling monitoring technology. The method is characterized by comprising the following steps of: searching features of the soon back imprest call in general packet radio service (GPRS); retrieving feature codes of the soon back imprest call according to the searched features of a soon back imprest platform in the GPRS; matching suspected feature codes according to a discrimination policy of black list feature codes, and taking the feature codes in accordance with the matching policy as the black list feature codes; and tracking the suspected feature codes, obtaining evidence, and submitting and intercepting the suspected feature codes which are in accordance with the preset policy features. According to the invention, through correlation analysis of GPRS network online records and calling records of an interface A, signaling behavior features in accordance with the soon back imprest can be found; and the problem that the novel soon back imprest cannot be identified in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical fields of telecommunication service support and telecommunication operation support, in particular to a method for identifying new malicious call-back services by using signaling monitoring technology. Background technique [0002] The callback service is referred to as SBIC (Soon Back Imprest Call), which means that the calling user first calls the callback system, and the system actively calls back to the calling user after hanging up. Service for calling and called users. [0003] The callback service utilizes the tariff policy that the called party is not billed to avoid call charges. Because the user never makes a call, there is no billing, which brings a lot of revenue loss to the operator and disrupts the normal communication market at the same time. For operators, it is particularly necessary to quickly discover such illegal services by adopting effective monitoring methods and to intercept them in time....
