Classified from the sending mode, multimedia message services can be divided into point-to-application multimedia message services and point-to-point multimedia message services. In the point-to-application multimedia message service, the sender of the multimedia message needs to input the communication number of the receiving terminal and the corresponding communication number of the service server used to manage the multimedia message when sending the multimedia message, so in MMSC (Multimedia Message Service Centre, After receiving the multimedia message, the multimedia message service center can send the multimedia message to the service server for corresponding management and then send it to the receiving terminal according to the communication number corresponding to the service server. In the point-to-point multimedia message service, the sender of the multimedia message only needs to input the communication number of the receiving terminal when sending the multimedia message, so that the MMSC can directly push the multimedia message to the receiving terminal.

According to statistics, among the above two multimedia message services, users are more accustomed to using point-to-point multimedia message services. The main implementation process of this service can be shown in Figure 1. When the sender and receiver belong to different MMSCs, the execution steps are as follows :

Step 101, the sender MMS (MultiMedia Service, multimedia service) terminal sends the multimedia message to the MMSC to which it belongs through a WAP (Wireless Access Protocol, wireless access protocol) gateway.

In this step, the sending MMS terminal needs to input the communication number of the receiving terminal when sending the multimedia message.

Step 102, after the sending party MMSC receives the multimedia message, resolve the communication number of the receiving terminal, and then forward this multimedia message to the MMSC to which the receiving party belongs (when the sending party's MMS terminal and the receiving party's MMS terminal belong to the same MMSC , this multimedia message does not need to be forwarded).

Step 103, the recipient's MMSC sends a multimedia message notification to the recipient's MMS terminal through an SMSC (Short Message Service Center, short message center).

Step 104: After receiving the notification of the multimedia message, the receiving MMS terminal sends a request for extracting the multimedia message to the MMSC to which it belongs.

Step 105, the recipient MMSC sends the multimedia message to the recipient MMS terminal according to the request of the recipient MMS terminal.

In the above-mentioned point-to-point multimedia message service, the user does not carry the communication number corresponding to the service server when sending the multimedia message, and the multimedia message cannot be managed by the service server like the point-to-application multimedia message service. The spread of some illegal multimedia content has also become increasingly prominent.
