Problems solved by technology

However, for normal users who frequently send text messages, because the frequency of sending short messages is relatively high, it also causes normal user numbers to be listed as spam SMS numbers, resulting in failure to send normal user text messages

Embodiment Construction

[0024] A method for improving the correct rate of identification of spam SMS numbers based on called dispersion. The implementation method is: set the called dispersion threshold; within the set time range, record each short message sent by the calling number, and The called number is added to the attribute of each SMS message; when the number of SMS sent by the calling number exceeds the threshold within the set time range, the called dispersion degree of the SMS sent by the calling number is calculated, that is, the non-repeated called number in the sent SMS The percentage of the number of numbers and the total number of text messages; when the called dispersion exceeds the set called dispersion threshold, the calling number is considered to be a spam SMS number; when the called dispersion does not reach the set called dispersion threshold , the calling number is not considered to be a spam SMS number.

[0025] The method includes the following steps:

[0026] First, record...

Abstract

The invention discloses a method for improving correct rate of identifying a junk short message number based on a called dispersed degree. The method comprises the following steps: setting a called dispersed degree threshold value; in a set time range, recording each short message sent by a calling number, and increasing a called number in attributes of each message; when the number of the messages sent by the calling number in the set time range exceeds the threshold value, calculating the called dispersed degree of the message sent by the calling number, namely the percentage of called numbers and total message numbers in the sent short messages; when the called dispersed degree exceeds the set called dispersed degree threshold value, regarding the calling number as the junk short message number; and when the called dispersed degree does not exceed the set called dispersed degree threshold value, considering that the calling number is not the junk short message number. By using the method, when short message flow rate is in over frequency, the sending behavior of a subscriber is analyzed according to the characteristics of the called number, thereby expelling normal short message numbers, reducing interception-failure efficiency of intercepting the junk short messages and improving the correct rate of indentifying the junk short messages.

Description

technical field [0001] The invention relates to a method for improving the accuracy of spam short message number identification when realizing statistics of short messages according to traffic, in particular to a method for improving the accuracy of spam short message number identification based on called dispersion. Background technique [0002] As a basic service of mobile communication network, short message service not only provides users with convenient message communication service, but also provides a channel for the dissemination of information garbage. However, spam messages are becoming more and more serious. Spam messages not only bring adverse effects of user complaints, but also have the problem of malicious arrears. Therefore, real-time monitoring and interception of spam messages is required. [0003] The time-frequency traffic characteristics of spam text messages include: 1. The continuous sending of short messages takes a long time; 2. The amount of time pe...
