Disclosed is a method for blocking SMS spam messages in an SMS server or a mobile terminal. If the server receives an SMS message to be transmitted to a subscriber from a base station, it is determined if a spam blocking option is set. If the spam blocking option is set, a spam-blocking database is accessed to search for a phone number corresponding to the received message, so as to check whether the number is registered in the database. If the SMS message phone number is registered in the spam-blocking database, the procedure is ended without SMS message-processing for the message, so that spam messages are blocked from being transferred to the subscriber. If the terminal receives an SMS message, a spam-blocking database in the mobile terminal is accessed to determine if the received message is an SMS spam message. If the received message is an SMS spam message, the terminal is controlled not to notify receipt of the message.

The invention belongs to the technical field of information, and provides a method and device for recognizing a junk short message. The method comprises the steps that participial processing is carried out on a received short message to obtain N participial phrases, and N is an integer larger than one; the probability index that the short message is a junk short message is calculated according to the matching result of the participial phrases of the short message in a preset junk short message lexicon; when the probability index of the short message is larger than a preset threshold value, the short message is recognized as the junk short message. According to the method and device for recognizing the junk short message, participial processing is carried out on the new short message received by a terminal, searching and matching are carried out on the participial phrases obtained through processing in the preset junk short message lexicon, whether the received new short message is the junk short message or not is recognized according to the searching and matching result, therefore, the junk short message is automatically and intelligently recognized, and can be recognized without manual operation, and resource consumption to the terminal is lowered.

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.
