3. The system according to claim 2 , further comprising a filter condition setting module which is configured to set the filter condition and synchronously send the filter condition to the real-time monitoring service processing modules.

4. The system according to claim 1 , further comprising a filter condition setting module which is configured to set the filter condition and synchronously send the filter condition to the real-time monitoring service processing modules.

5. A method for filtering out a key word in a long short-message, comprising:

step 1 : receiving, by a short message center and/or a short message gateway, a long short-message from a user, and splitting the long short-message into a plurality of split messages, and sending the plurality of split messages to a network security agent module; decoding, by the network security agent module, the plurality of split messages, and sending the plurality of decoded split messages to a real-time monitoring service processing module; and sending, by the real-time monitoring service processing module, the plurality of decoded split messages to a long message splicing module;

step 2 : splicing, by the long message splicing module, the plurality of decoded split messages into an integrated long message, and sending the integrated long message to the real-time monitoring service processing module;

step 3 : filtering, by the real-time monitoring service processing module, the integrated long message according to a filter condition of matching a key word of the integrated long message content and returning a filter result to the network security agent module.

6. The method according to claim 5 , further comprising: before the step 1 , setting the filter condition and synchronously sending the filter condition to the real-time monitoring service processing modules; and

step 4 : after the step 3 , returning the filter result to the short message center and/or the short message gateway by the network security agent module.

7. The method according to claim 6 , wherein

there are a plurality of real-time monitoring service processing modules; and the step of sending, by the network security agent module, the plurality of decoded split messages specifically comprises: distributing, by the network security agent module, the plurality of decoded split messages to one of the plurality of real-time monitoring service processing modules according to mantissa of a user number.

8. The method according to claim 7 , wherein the step 2 specifically comprises: caching, by the long short-message splicing module, the plurality of decoded split messages, if all of the plurality of decoded split messages belonging to a same long short-message are cached, then splicing all of plurality of the decoded split messages belonging to the same long short-message into the integrated long message and sending the integrated long message to the one of the plurality of real-time monitoring service processing modules.

9. The method according to claim 7 , wherein there are sessions in the real-time monitoring service processing module, and each of the plurality of decoded split messages corresponds to one session;

in the step 2 , the step of sending the integrated long message to the real-time monitoring service processing module specifically comprises: returning the integrated long message to a first session corresponding to a first split message of the integrated long message.

10. The method according to claim 9 , wherein the step 3 further comprises: returning, by the real-time monitoring service processing module, the filter result to the long message splicing module; returning, by the long message splicing module, the filter result to other sessions except the first session corresponding to other split messages of the integrated long message in the real-time monitoring service processing module; and

in the step 4 , the step of returning the filter result to the short message center and/or the short message gateway specifically comprises: returning the filer result to the short message center and/or the short message gateway as a filter result of all the split messages in the integrated long message.

11. The method according to claim 5 , wherein

there are a plurality of real-time monitoring service processing modules; and the step of sending, by the network security agent module, the plurality of decoded split messages specifically comprises: distributing, by the network security agent module, the plurality of decoded split messages to one of the plurality of real-time monitoring service processing modules according to mantissa of a user number.

12. The method according to claim 11 , wherein the step 2 specifically comprises: caching, by the long short-message splicing module, the plurality of decoded split messages, if all of the plurality of decoded split messages belonging to a same long short-message are cached, then splicing all of the plurality of decoded split messages belonging to the same long short-message into the integrated long message and sending the integrated long message to the one of the plurality of real-time monitoring service processing modules.

13. The method according to claim 11 , wherein there are sessions in the real-time monitoring service processing module, and each of the plurality of decoded split messages corresponds to one session;
