Short message filtering method and system, short message service center and terminal

Abstract

The invention discloses a short message filtering method and system, a short message service center and a terminal. The method includes the steps that the short message service center generates the address information in a service center address field through a private short message center address; when the terminal receives a short message, whether the address information carried in the short message is consistent with the private short message center address stored in the private short message or not is judged, and when the address information is not consistent with the private short message center address, the received short message is filtered. According to the method, due to the fact that only certain public short message service center addresses are carried in illegal short messages sent by a pseudo base station, the pseudo base station in the method cannot acquire the private short message center addresses to be used as short message source address information, and thus the illegal short messages such as fraud short messages or junk short messages sent by the pseudo base station can be effectively filtered.

Description

technical field [0001] The invention relates to short message processing technology, in particular to a short message filtering method, system, short message service center and terminal. Background technique [0002] Pseudo-base station is a technology that uses the mobile signaling monitoring system to monitor various signaling processes in the mobile communication process to obtain the current location information of mobile phone users. When the location information of the user, such as the cell ID (Cell ID), is consistent with the specific area selected by the service, a short message customized for the service will be delivered to the user. [0003] Some lawbreakers use fake base stations to carry out illegal activities. User mobile phones often receive illegal text messages from fake base stations, such as fraudulent text messages or spam text messages. The text message numbers of these text messages can be forged into arbitrary text message numbers by pseudo base stati...

Problems solved by technology

[0005] However, because the pseudo-base station often changes the short message number to the short message number of some public service agencies when sending fraudulent short messages or spam short messages, such as the short message number of the bank or the short message number of the operator, therefore, the existing short message filtering method It is very likely that the fake SMS number is considered as a white list because it belongs to a public service agency number, so that it cannot effectively filter fraudulent SMS or spam SMS

On the other hand, since the fake base station SMS may process its content when it is sent out, such as adding separators such as "*" to avoid keyword filtering, so that the risky content in the SMS content cannot be correctly identified, this also reduces Effective filtering of illegal text messages such as fraudulent text messages or spam text messages
