Step 107, the receiver terminal obtains the newly encrypted MM from the media transfer server according to the address of the media transfer server and the MMID.

Step 108, the receiver terminal decrypts the newly encrypted MM to obtain the MM.

Based on the communication service processing method provided by the above-mentioned embodiments of the present invention, the WEB server, the multimedia switching center and the multimedia delivery server can send multimedia messages to fixed network terminals in a unicast manner, saving limited network bandwidth resources and reducing the burden on the network system. Work burden: MMS is encrypted for transmission, which effectively prevents user information leakage caused by illegal interception of messages.

As a specific implementation of the communication service processing method of the present invention, in step 108 of the embodiment shown in FIG. 1, after the receiver terminal obtains the MM, the following process may also be executed to realize charging for the MM:

The receiver terminal sends a reading report to the media delivery server according to the address of the media delivery server;

The media delivery server forwards the reading report to the media switching center;

The media switching center forwards the reading report to the WEB server, and sends the billing information of the short message to the CDR receiver;

The CDR receiver forwards the charging information of the short message to the charging system, so that the charging system can charge the short message.

In addition, as another specific implementation of the communication service processing method of the present invention, in step 101 of the embodiment shown in Figure 1, before the media switching center returns the address of the media delivery server to the WEB server, the following process may also be included:
