The platform can use enterprise code, and there are options to configure whether the application platform supports content adaptation. Performing service analysis on the received multimedia data content. If the target number of the message is found to be a message that needs to be forwarded to another service platform, look up the identifier of the service platform, for example, if the peer end is a multimedia message processing center, look for it. The domain name, if it is a value-added business platform, find its enterprise code. S13: obtaining, according to the code, a length, a type, and a corresponding format of the data processing item of the destination platform; for example, processing a txt text character data item 200k, processing a jpg format picture 50k, processing an rmvb format video 500k, and the like.

S 14: converting the parsed data items according to the type and format of the data items processed by the destination platform, and the converted data item length is smaller than the length of the data processing item processed by the destination platform; Converting separately, for example, converting text in word and PDF format to text in txt format, converting audio in mp3 format to audio in WMA format, converting image in jpg format to image in bmp format, and pixel conversion of image. The video can convert video in h.264 format to video format in rmvb format. Before the conversion, it is also necessary to judge whether the size of each data item converted can be processed by the destination platform, for example: the video size before conversion is 50k, and after conversion, it becomes 200k, when it is judged that the length of the converted data item is larger than the purpose When the platform processes the length of the data item, it stops the conversion and returns the result that cannot be converted. If it is determined that the length of the converted data item is less than the length of the data item processed by the destination platform, the conversion is performed, and the message formed by the converted data items is forwarded.

In the multimedia message processing center, the information of different application platforms is configured, and there are several categories of multimedia message processing centers, value-added service platforms, and mail servers. Each platform in each category has different unique identifiers, for example: multimedia The message processing center can use the domain name, the value-added service platform can use the enterprise code, and there are options such as whether the application platform supports the content adaptation function. Through the parsed destination address, the destination platform code to which the destination address belongs and receives the multimedia data content can be found. The multimedia message processing center performs service analysis on the received multimedia message. If the target number of the message is a message that needs to be forwarded to another service platform, the identifier of the service platform is searched, for example, if the peer end is a multimedia message processing center. Then look up its domain name, if it is a value-added business platform, look up its enterprise code. The multimedia message processing center treats these identifiers as UAProfile information and submits them to the content adaptation platform in the ConetentAdapt.REQ message. The content adaptation platform performs the conversion operation. After receiving the ConetentAdapt.REQ message, the content adaptation platform searches the local UAProfile configuration database according to the UAProfile information in the request, and then converts the format and size of the multimedia message carried in the ContentAdapt.REQ message according to the configuration database information. After the adaptation is successful, the message is returned to the multimedia message center through ContentAdapt.ACK. Configuring multimedia message processing parameters of different service platforms on the content adaptation platform, the parameters mainly include: the size of the multimedia message supported by the application platform, the type and format of the multimedia message that can be processed on the platform, and whether the synchronous multimedia is supported.

The content adaptation platform obtains the identifier of the service platform according to the UAProfile information in the request, and searches for the corresponding configuration parameter according to the identifier. For example, processing parameters of various service data such as data processing length, text processing capability, picture format parameters, video format parameters, and audio format parameters of the destination platform. Each data item in the content adaptation platform multimedia message is converted separately, for example, converting text in word and PDF format into text in txt format, converting audio in mp3 format into audio in WMA format, and converting image in jpg format For bmp format pictures, and pixel conversion of pictures, video can convert h.264 format video to rmvb format video format. Before the conversion, it is also necessary to judge whether the size of each data item converted can be processed by the destination platform, for example: the video size before conversion is 50k, and after conversion, it becomes 200k, when it is judged that the length of the converted data item is larger than the purpose When the platform processes the length of the data item, it stops the conversion and returns the result that cannot be converted. If it is determined that the converted data item length is less than the length of the destination platform processing data item, the conversion is performed, and the message formed by the converted each data item is returned to the multimedia message processing center.

S25: The content adaptation platform replies to the multimedia message processing center with a ContentAdapt RES message. The content adaptation platform replies to the ContentAdapt RES message to the multimedia message processing center, and adds the result of the conversion, such as the result that cannot be converted, or the converted data item. Messages can also be returned to the multimedia message center via a ContentAdapt.ACK message.

S26: The multimedia message processing center sends a Forward.REQ message to the application platform. If the content adaptation platform is successfully converted, the multimedia message processing center sends the converted message containing each data item to the application platform.
