Problems solved by technology

If the frequency value is set too high, the source of spam messages will be missed; if the frequency value is set too small, the false blocking rate will be high; if the keyword setting conditions are simple, it is easy to cause false blocking; if the keyword is complex, it cannot be completely covered

Embodiment Construction

[0033] A method for identifying spam sources based on keywords and frequencies, comprising:

[0034] Set the corresponding relationship between keywords and keyword codes;

[0035] Set keyword SMS frequency threshold, the keyword SMS frequency threshold is the maximum threshold of violating the same keyword within a period of time;

[0036] Set the blacklist threshold, that is, the maximum threshold of the number of different keywords whose calling source exceeds the keyword SMS frequency threshold within the set time range. If the maximum threshold is exceeded, it will be blacklisted for interception;

[0037] Receive text messages, judge whether they violate the set keywords, and record the text messages sent by the calling source that violate the keywords;

[0038] When the number of short messages violating the same keyword sent by the calling source within the set time range exceeds the maximum threshold of the short message frequency threshold of the keyword, the short ...

Abstract

The invention discloses a keywords and frequency based method for identifying spam message sources. The method comprises the following steps: setting a keyword message frequency threshold which is the maximum threshold value violating the same keyword in a period, and blocking messages of a calling source in accordance to the keyword when the number of messages transmitted by the calling source violating the same keyword exceeds the maximum threshold value of the keyword message frequency threshold; and setting a blacklist threshold, namely setting the maximum threshold value which is the number of different keywords of the calling source exceeding the keyword message frequency threshold, determining the calling source to be a spam message source when the number of the calling source violating different keywords exceeds the maximum threshold value, and blocking all messages of the calling source. The method can effectively block spam messages by adopting a mode of combining keywords with frequency and listing sources violating a plurality of keywords simultaneously in the blacklist according to the sending characteristics of spam messages.

Description

technical field [0001] The invention relates to the field of telecommunications, in particular to the monitoring and management of spam short messages, and relates to a method for identifying the source of spam short messages in combination with keywords and sending frequency. 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 sending characteristics of spam text messages are: 1. The frequency of sending is relatively high; 2. The content is repeated, and most of them are scams or advertisements, which meet the characteri...
