Abstract

The invention discloses a telephone network illegal traffic screening method and device, and relates to the field of telephone network traffic screening. The method includes: the first step of comparing the existing network call information database with the existing abnormal call model database; the calls that meet the abnormal call rules are classified into the abnormal call database, and the calls that do not conform to the current network call information database are classified into the existing network call information database; The second step is compared with the reference call model library in the network call information database two; abnormal call models are established for calls that do not meet the reference call rules, and the abnormal call models are classified into the existing abnormal call model library, and those that do not meet the reference call rules The call is classified into the abnormal call database; the basic content of the current network call information database and the existing abnormal call model library is composed of the call information context, which is extracted from the call signaling; the composition of the reference call model library is composed of the call migration reference State diagram composition. The invention can proactively and timely discover illegal traffic, and the screening accuracy rate of the two-layer screening technology is high.

Description

technical field [0001] The invention relates to the field of telephone network traffic screening, in particular to a method and device for screening illegal telephone network traffic. Background technique [0002] Although the telephone network has a set of scientific and effective networking principles and routing principles to standardize the configuration of the telephone network, due to the relatively complex network structure and business logic of the telephone network, and the huge amount of call information on the existing network, there are still some loopholes or Unclear business rules, lawbreakers exploit the loopholes of the existing network to seek personal gain, such as using illegal callers on the Internet to obtain settlements, and illegal callers to implement fraud. [0003] Since illegal calls are submerged in a large number of normal calls, the workload of manual screening is huge. Operators can only conduct manual screening according to user complaints or ...
