Problems solved by technology

For some organizations or individuals, abnormal calls may be initiated for various purposes, which has a huge impact on telecommunications network users who normally use telecommunications services
[0003]At present, the vast majority of abnormal calls are initiated abroad and landed in China, it is difficult to determine the location of the caller, and because most of the caller numbers of abnormal calls are false The calling party cannot accurately determine the calling number of the abnormal call and issue an early warning in time, making it difficult to trace back

Abstract

The embodiment of the invention discloses an abnormal call detection method and device, equipment and a medium. The method comprises the following steps: acquiring various types of call record description data; forming at least one multi-source data group according to the call record description data, wherein the multi-source data group comprises at least two types of call record description data; and performing association analysis on the call record description data included in each multi-source data packet to form an abnormal call detection result corresponding to each multi-source data packet. According to the technical scheme, the abnormal call detection result is obtained by performing association analysis on the various types of call record description data, so that effective safety supervision on the abnormal call is realized, and the detection accuracy of the abnormal call is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of communication network security, and in particular, to an abnormal call detection method, device, equipment and medium. Background technique [0002] With the continuous development of traditional telephone services or new communication services such as VoIP (Voice over Internet Protocol), the means of dissemination of various types of spam calls, such as fraud, harassment, or sales promotion, are constantly escalating. For some organizations or individuals, abnormal calls may be initiated for various purposes, which has a huge impact on telecommunications network users who normally use telecommunications services. [0003] At present, the vast majority of abnormal calls are initiated abroad and landed in China. It is difficult to determine the location of the caller, and since most of the calling numbers of the abnormal calls are false calling parties, it is impossible to accurately ...
