Abstract

The present invention discloses a method for realizing content adaptation and a content adaptation server, the method includes: receiving a multimedia message from a calling terminal, wherein contents of the multimedia message and a model of a called terminal are included in the multimedia message; determining the multimedia formats supported by the called terminal according to the model of the called terminal, and selecting an optimum multimedia format from them; and compressing the multimedia message according to the selected optimum multimedia format, and sending the compressed multimedia message according to the maximum size of the multimedia message supported by the called terminal. Based on the present invention, the presentation effect of the contents of the multimedia message can be enhanced and the user experience can be improved by selecting the optimum multimedia format to compress the multimedia message according to the model of the called terminal.

Claims

1. A method for realizing content adaptation, including:

receiving a multimedia message from a calling terminal, wherein contents of the multimedia message and a model of a called terminal are included in the multimedia message, the calling terminal having included the model of the called terminal into the multimedia message;

determining multimedia formats supported by the called terminal according to the model of the called terminal, and selecting an optimum multimedia format from them; and

compressing the multimedia message according to the selected optimum multimedia format, and sending the compressed multimedia message according to the maximum size of the multimedia message supported by the called terminal.

2. The method according to claim 1, wherein the process of compressing the multimedia message specifically includes:

according to a multimedia type, the received contents of the multimedia message are divided into different types of multimedia message content segments, wherein the multimedia type includes pictures, audios, videos and texts; and

different types of the multimedia message content segments are compressed respectively, and individual compressed multimedia message content segments are assembled into the compressed multimedia message.

3. The method according to claim 1, wherein the process of sending the compressed multimedia message according to the maximum size of the multimedia message supported by the called terminal specifically includes:

if the size of the compressed multimedia message is smaller than or equal to the maximum size of the multimedia message supported by the called terminal, then the compressed multimedia message is sent directly; and

if the size of the compressed multimedia message is greater than the maximum size of the multimedia message supported by the called terminal, then the compressed multimedia message is divided into multiple sub-multimedia-messages, wherein the size of each sub-multimedia-message is all smaller than or equal to the maximum size of the multimedia message supported by the called terminal.

4. The method according to claim 1, further including:

a multimedia message center receiving the compressed multimedia message;

the multimedia message center decomposing the compressed multimedia message;

in the case that one multimedia message is obtained through decomposition, the multimedia message center directly sending the multimedia message obtained through decomposition to the called terminal; and

in the case that multiple sub-multimedia-messages are obtained through decomposition, the multimedia message center sending one sub-multimedia-message to the called terminal, and locally saving the rest of the sub-multimedia-messages to be used for subsequent sending.

5. The method according to claim 4, wherein the process of locally saving the rest of the sub-multimedia-messages to be used for subsequent sending specifically includes:

after receiving a message acknowledgement response from the called terminal, the multimedia message center sends another sub-multimedia-message to the called terminal.

9. The method according to claim 2, further including:

a multimedia message center receiving the compressed multimedia message;

the multimedia message center decomposing the compressed multimedia message;

in the case that one multimedia message is obtained through decomposition, the multimedia message center directly sending the multimedia message obtained through decomposition to the called terminal; and

in the case that multiple sub-multimedia-messages are obtained through decomposition, the multimedia message center sending one sub-multimedia-message to the called terminal, and locally saving the rest of the sub-multimedia-messages to be used for subsequent sending.

10. The method according to claim 3, further including:

a multimedia message center receiving the compressed multimedia message;

the multimedia message center decomposing the compressed multimedia message;

in the case that one multimedia message is obtained through decomposition, the multimedia message center directly sending the multimedia message obtained through decomposition to the called terminal; and

in the case that multiple sub-multimedia-messages are obtained through decomposition, the multimedia message center sending one sub-multimedia-message to the called terminal, and locally saving the rest of the sub-multimedia-messages to be used for subsequent sending.

11. The method according to claim 9, wherein the process of locally saving the rest of the sub-multimedia-messages to be used for subsequent sending specifically includes:

after receiving a message acknowledgement response from the called terminal, the multimedia message center sends another sub-multimedia-message to the called terminal.

12. The method according to claim 10, wherein the process of locally saving the rest of the sub-multimedia-messages to be used for subsequent sending specifically includes:

after receiving a message acknowledgement response from the called terminal, the multimedia message center sends another sub-multimedia-message to the called terminal.

6. A content adaptation server for use with a calling terminal having a model, the calling terminal disposed to include the model of a called terminal into a multimedia message, including:

a receiving module, which is used for receiving a multimedia message from the calling terminal, wherein multimedia contents and the model of a called terminal are included in the multimedia message;

a determining module, which is used for determining multimedia formats supported by the called terminal according to the model of the called terminal and selecting an optimum multimedia format from them;

a compressing module, which is used for compressing the multimedia message according to the optimum multimedia format selected by the determining module; and

a sending module, which is used for sending the multimedia message compressed by the compressing module according to the maximum size of the multimedia message supported by the called terminal.

7. The content adaptation server according to claim 6, wherein the compressing module comprises:

a splitting module, which is used for dividing the received contents of the multimedia message into different types of multimedia message content segments according to a multimedia type, wherein the multimedia type includes pictures, audios, videos and texts;

a compressing sub-module, which is used for compressing the different types of the multimedia message content segments respectively; and

an assembling module, which is used for assembling individual compressed multimedia message content segments into the compressed multimedia message.

8. The content adaptation server according to claim 6, wherein the sending module comprises:

a first sending module, which is used for directly sending the compressed multimedia message if the size of the compressed multimedia message is smaller than or equal to the maximum size of the multimedia message supported by the called terminal; and

a second sending module, which is used for dividing the compressed multimedia message into multiple sub-multimedia-messages and sending them if the size of the compressed multimedia message is greater than the maximum size of the multimedia message supported by the called terminal, wherein the size of each sub-multimedia-message is all smaller than or equal to the maximum size of the multimedia message supported by the called terminal.

13. The content adaptation server according to claim 7, wherein the sending module comprises:

a first sending module, which is used for directly sending the compressed multimedia message if the size of the compressed multimedia message is smaller than or equal to the maximum size of the multimedia message supported by the called terminal; and
