S101, the sender terminal (here set to terminal A) receives from MMSC (Multimedia WAP Push (Wireless Application Protocol Push) message of the Messaging Service Center, the WAP Push message refers to a notification indication message sent by the MMSC, which includes at least X-MMS-Message-Type and X-MMS-Content- The two fields of the location, the X-MMS-Message-Type field is filled with the type of the push message, and is used in the embodiment of the present invention to indicate that the type of the WAP Push message is a notification indication message, and the X-MMS-Content-Location field is a URL address indicating the location where the multimedia information is stored, that is, telling the recipient terminal (here set to terminal B) where to obtain the content of the multimedia information;

5102, terminal A opens a temporary storage space Space-A, and stores the WAP Push message received in S101 in the storage space Space_A for use in subsequent processes;

5103, terminal A prompts the user whether to download the multimedia information immediately;

5104, terminal A collects the user's selection, determines whether to download the multimedia information immediately, when the user chooses to download immediately, then proceeds to S105, otherwise directly to S106;

5105. The terminal A downloads the multimedia information in the temporarily created temporary storage space Space_B from the MMSC according to the WAP Push message received in S101. The process follows the MMS Retrieve process defined by the 3GPP standard, and may also be processed after the download is completed. The download confirmation message is stored in the temporary storage space Space_B, and then S106 is executed;

5106, terminal A prompts the user whether to forward the multimedia information from the network;

5107, terminal A collects the user's selection, and determines whether the multimedia information is directly forwarded from the network. If the user chooses to forward the multimedia information directly from the network, the user turns to S111, otherwise, the user turns to

S121 ;

S111, the terminal A extracts the WAP Push message received by the S101 from the Space_A, and parses the WAP Push message, that is, extracts the contents of the fields X-MMS-Message-Type and X-MMS-Content-Location, and obtains the content. The type of the WAP Push message is a notification indication message, and a location where the multimedia information is stored; 5112: Repacking the location where the multimedia information is stored to generate a special short message, that is, the multimedia forwarding short message, and adding a special flag bit therein, indicating that the short message is a non-normal short message, but a special for multimedia forwarding The short message can be identified by the special flag Flag-1, where the special flag Flag-1 can be added or modified in the short message header; it should be noted that the terminal needs to download the multimedia information from the MMSC. Authentication, so the problem of authentication needs to be solved when re-packaging the short message; specifically, terminal A can authorize terminal B, and authorize the designated terminal B to directly extract corresponding multimedia information from the MMSC, thus requiring terminal A The authorization code given to the terminal B is encapsulated into the multimedia forwarding short message together with the location where the multimedia information is stored, and the authorization code is also sent to the Proxy-Relay in a certain form, the certain form Can be carried by short message, or by USSD (Unstructured Supplementary Service Data, unstructured supplementary data service); and, the above-mentioned multimedia forwarding short message can be defined as a special short message such as a ClassO short message, that is, the content is not directly displayed after being sent to the receiving party, but is received in the background, and is analyzed by the receiving terminal. After being displayed to the user in other forms, further improving the user experience can also avoid causing confusion of the user; in addition, a flag bit Flag_2 can be added to the multimedia forwarding short message to mark whether the receiving terminal selects according to this short The message downloads the corresponding multimedia information, and forces the recipient terminal to return a download confirmation message;
