Method and device for identifying false caller numbers

Abstract

An embodiment of the present invention provides a method and device for identifying a false caller number, the method comprising: sending a request for routing information SRI request to the user home register HLR to which the caller number to be identified belongs; acquiring the SRI message of the caller number to be identified, and Analyzing the current state of the user of the caller number to be identified from the SRI message; if it is determined that the current state is other than being in a call, then determining that the caller number to be identified is a false caller number. The method and device for identifying a false caller number provided by the embodiments of the present invention directly send a signaling SRI request to the user home register HLR, and analyze the SRI message to obtain the current status of the number to be identified, and determine whether the number to be identified is a fake number based on the current status , no need for network allocation of session resources, no need for callback, avoiding harassment of real users, saving resources, and improving identification efficiency.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of communication, and in particular to a method and device for identifying a fake caller number. Background technique [0002] Criminals use number changing software to call public security bureaus, emergency centers, governments, or enterprises and institutions, and incidents of false reports and malicious harassment emerge in endlessly, resulting in a waste of social resources such as police force, medical care, and public services to a certain extent. Users who really need it cannot get assistance and services, which has caused a bad social impact. If enterprises and institutions can judge the authenticity of the caller number when receiving a call, they can take effective measures to greatly reduce or even avoid the occurrence of such incidents. [0003] In the prior art, the authenticity of the caller number is judged by the callback method. Specifically, when the caller numbe...

[0004] However, the actual situation is more complicated. For example, if a real user calls, and the terminal used by the real user happens to be in the process of switching between two cells, at this time, the prompt tone of the caller number may be that it cannot be connected or is not in an unacceptable area, but Using the discrimination method in the prior art, it will be discriminated as a false call, therefore, using the method in the prior art to discriminate, the accuracy is low

In addition, from obtaining the caller number, calling back the caller number, and finally getting the call back prompt tone, it takes a certain amount of time to wait and consume existing resources, resulting in low discrimination efficiency and waste of resources

Also, if the caller number is a real number changed by the number changing software, it will inevitably harass normal users and reduce the work efficiency of the staff of enterprises and institutions
