[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and examples.

[0017] The method proposed by the present invention will be described below by taking the GSM system as an example. According to the GSM protocol (similar to the CDMA protocol), when the sender successfully sends the short message, it will be sent to the designated user after the short message center confirms the success. At this time, the user's mobile phone protocol layer should receive the SMS-DELIVER packet, which contains TP-MTI (short message type indication), TP-MMS (whether there is a continuous short message transmission flag), TP-RP (response path), TP-UDHI (user data header indication), TP-SRI (status report indication) , TP-OA (sender address), TP-PID (sending protocol identification), TP-DCS (short message data coding method), TP-SCTS (short message center time when sending), TP-UDL (sending data length) , TP-UD (send data content) ...
