Rubbish short message recognition system and method based on calling number location and transmitted content

Abstract

The invention relates to a rubbish short message identification system based on the position of the calling number and transmitted content and a method thereof, comprising: judging whether the amount of the transmitted short message having the same content reaches a first threshold, if true, counting the occurrence number of the position information of the calling number on the transmitted short message with the same content subsequent; judging the short message with the same content as the rubbish short message, if the sum of the occurrence number of the position information of all calling number of the short message with the same content reaches a second threshold, or if the sum of the occurrence number of the position information of any calling number of the short message with the samecontent reaches a third threshold; transmitting the calling number of the rubbish short message to a short message center, for filtering the rubbish short message for the short message center. The invention ensures that a great deal of short messages received by the short message center are filtered, sorted and processed in real time and high efficiency, and performs real time interception on therubbish short message.

Description

technical field [0001] The invention relates to spam short messages, in particular to a spam short message identification system and method based on the calling number position and sending content. Background technique [0002] In recent years, the flooding of spam messages has intensified, and almost every mobile phone user has been harassed by spam messages. According to the survey results released by the Internet Society of China, mobile phone users in my country receive an average of 8.29 spam messages per week.

The spam short messages sent by this method have the characteristics of fast speed, simple operation, and the need for the operator's permission. Mos...

Problems solved by technology

The advantage of this method is that the system is easy to implement, but there are two disadvantages: (1) the threshold value of the number of short messages sent in the same number unit time is difficult to define, if it is set too large, the effect of interception and filtering cannot be reached; It is too small, and it is easy to intercept and filter the normal short messages of normal users (with the popularization of smart phones, some mobile phones can support batch sending of short messages); (2) the threshold parameter is easy to be tested by spam senders. Once discovered, they can adjust their speed to avoid being monitored and intercepted
