Detailed ways

The core idea of the present invention is to provide a method for a terminal to recall a multimedia message. The sending terminal sends a multimedia message recall request through the MM1 interface, and receives a response message fed back by the MMSC (Multimedia Message Service Center), and the MM4 interface completes the message retrieval between MMSCs. Forwarding, the MMSC completes the cancellation operation of the corresponding multimedia message according to the message carried in the recall request message.

The present invention provides a method for a terminal to recall a multimedia message. Referring to FIG. 1, it is a flow chart of the method operation of the present invention. The method specifically includes:

Step 10: the sending terminal sends a multimedia message recall request to the MMSC;

After the sending terminal sends the multimedia message, if the address of the receiving terminal of the sent multimedia message is wrong or the sent content is wrong, it needs to recall the sent multimedia message. At this time, the sending terminal of the multimedia message will send the recall request message through the MM1 interface , sent to the MMSC in the form of a MM1_cancel_originator.REQ request message, the recall request message carries the ID of the multimedia message to be recalled, the number of the receiver to be recalled, and the multimedia message index, and the multimedia message index is used for the sending terminal to request When storing the sent multimedia message in the MMbox (multimedia message storage box), utilize this index to search for the corresponding multimedia message;

Step 11: After receiving the recall request, the MMSC sends a response message to the sending terminal, indicating that the MMSC has received the recall request and is processing the request;

After the MMSC receives the recall request, it locates the specific message according to the multimedia message identification carried in the recall message, and returns a failed response message if the positioning message fails; if the message is successfully located, then returns a successful response message; the response The message can be sent to the sending terminal in the form of MM1_cancel_originator.RES message;

Step 12: MMSC executes operations related to recalling multimedia messages;

If the sending terminal requires that the multimedia message sent be stored in the MMbox, the MMSC first deletes the multimedia message stored in the MMbox, and then performs a recall operation according to the current state of the message, which can be divided into the following situations:

1) If the MMSC has not yet sent the multimedia message arrival notification to the receiving terminal, then the MMSC deletes the multimedia message, no longer sends the multimedia message recall request to the receiving terminal, and no longer sends the multimedia message arrival notification to the receiving terminal, and Return the multimedia message recall report; then the response message can be sent to the sending terminal in the form of MM1_cancel_report.REQ;

2) If the MMSC has sent the arrival notification of the multimedia message to the receiving terminal, but the receiving terminal has not successfully obtained the multimedia message, the MMSC deletes the multimedia message and returns a multimedia message recall report. The response message can be sent as MM1_cancel_report.REQ The form is sent to the sending terminal, and the MMSC returns a corresponding reminder when the receiving terminal obtains the multimedia message later, such as returning a reminder that the multimedia message has been recalled;

3) If the multimedia message has been successfully acquired by the receiving terminal, then perform step 13;

Step 13: The MMSC sends a multimedia message recall request MM1_cancel.REQ message to the receiving terminal, notifying the receiving terminal to delete the corresponding multimedia message;

Step 14: The receiving terminal feeds back the processing result to the MMSC, which can be sent to the MMSC in the form of MM1_cancel.RES message;

Step 15: MMSC judges whether the receiving terminal deletes the message successfully according to the response message returned by the receiving terminal, and returns the result to the sending terminal through the MM1_cancel_report.REQ message;

After the above positioning is successful, if it is found that the message has been forwarded to other MMSC, then send a recall multimedia message request MM4_cancel.REQ to the corresponding receiver MMSC, as shown in Figure 2, the receiver MMSC performs the above operations Recall the multimedia message, and return the recall operation response to the sender MMSC, the information interaction between the MMSCs is completed through the MM4 interface, and the recall response message is returned to the sender MMSC in the form of MM4_cancel.RES;

After the MMSC receives the recall request in the above operation process, it may not send a response message to the sending terminal, and return to the sending terminal in the form of sending a response message together with the processing result report after processing, as shown in FIG. 3 .
