Description

Method, device and terminal for transmitting multimedia message

Technical field

The present invention relates to a multimedia message transmission technology in the field of mobile communication, and in particular, to a multimedia message transmission method, apparatus, and terminal.

Background technique

MMS, also known as Multimedia Messaging Service (MMS), the biggest feature of MMS is to support multimedia functions, which can transfer text, images, and between terminals and terminals, between terminals and the Internet, between terminals and E-mail. Information in various multimedia formats such as sounds and animations. Compared with SMS, MMS can transmit pictures and music, and it is more popular.

In addition to text, MMS can also include information in various media formats such as images, sounds, and data, and users can edit the information themselves. The most attractive application of MMS is to use it in conjunction with the camera function of the terminal to instantly send photos taken with the terminal to relatives or friends. Another big application of MMS is that users can download it on the website or send some special color letters to friends, such as: holiday blessings, love songs, entertainment jokes, etc. Of course, users can also customize MMS news for themselves.

At present, MMS technology first combines pictures, audio, video, text and other elements according to the smil format. If it is text, it is encoded according to the encoding format such as UTF8. If it is picture, audio or video, the binary data of the whole file of the picture, audio or video is packed into it, and then encoded into a PDU string and sent to the MMS server. Due to network restrictions, the current network can only send a maximum of a few hundred KB of MMS files. For an oversized MMS file, the MMS server will fail. Since MMS can insert text, pictures, audio or insert video files through attachments, it is easy to exceed the capacity limit of MMS server, and can only be sent through multiple lines, which will increase the tariff and make it difficult for users to preview.

The patent CN200810094333.X reduces the capacity by adjusting the size of the picture inserted in the MMS file to ensure that the MMS size does not exceed the upper limit value. This may cause distortion of the picture during the adjustment process, and it cannot be adjusted for audio and video data.

In order to make the objects, the technical solutions and the advantages of the present invention more clearly, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments of the present application may be arbitrarily combined with each other.

In the embodiment of the present invention, a large-capacity multimedia message is sent through a single strip by changing the content of each element (such as picture, audio, video, etc.) packaged in the multimedia message file. In the data packaging process, the actual non-text information is not packaged, but the link address or the server address corresponding to the non-text information to be sent is packaged, so that the MMS size is greatly reduced, the transmission capacity can be greatly reduced, and the terminal and the device are saved. The memory of the PC. Wherein, the non-text information is one of a picture, an audio, a video, a data, or a combination thereof.

A method for sending a multimedia message according to an embodiment of the present invention includes:

When the non-text information to be sent is local, the non-text information is uploaded to the data management server, and the link address is recorded, and the link address is packaged into a multimedia message packet in a multimedia message format, and sent to the multimedia message server.

The method further includes: when the non-text information to be sent is located in the network, the link address is packaged into a multimedia message data packet in a multimedia message format, and sent to the multimedia message server.

The method further includes: when there is still text information to be sent, and further packaging the non-text information to be sent together in a multimedia message format.

The embodiment of the invention uses the following technical solutions:

Before sending, if the text to be sent is text, it is encoded (such as UTF8 encoding); if the non-text information stored in the terminal is to be sent, it is uploaded to the data management server, and its link address is recorded; If the non-text information on the network is not downloaded to the local, the link address can be directly recorded. The link address (including text if there is text) is packaged into a multimedia message packet in the MMS format and sent to the MMS server. A specific packing method is as follows: According to the Smil format combination, it is packaged into a PDU string. When the MMS recipient receives the MMS, it parses the elements of each frame in the MMS file according to the smil protocol. If there is a link address in the content, go directly to the chain Download the relevant content from the address, combine each frame and each element according to the smil format, and preview and play the multimedia message.

The following describes the complete implementation of MMS from sending to receiving, including:

Step 1: Create a new MMS interface, add a new menu to the options for inserting each element, such as insert picture menu, display as: Insert local picture / audio / video, insert picture / audio / video in the link, select a menu, insert element. Step 2: If the element to be inserted is not text and the element is saved locally, upload it to the data management server and record its link address. If the element to be inserted is on the network, simply record the link address of the element.

The elements here can be picture/video/audio, etc.

Step 3: After the user clicks and sends, the encoding module first packs each frame and each element according to the Smil format. The information of the non-text element is the link address of the element.

Step 4: Encode the data into a PDU string, add the header information such as the sender, the recipient, and the validity period, and establish a Socket connection with the MMS server to upload the entire data packet to the MMS server.

Step 5: The MMS server sends the MMS notification message of the MMS to the MMS recipient according to the recipient information.

Step 6: When the MMS recipient clicks to download the MMS message, the MMS data packet is downloaded from the MMS server, and the MMS data packet is parsed according to the MMS protocol and the coding specification. If the non-text information is parsed, the header data is first parsed to determine whether the link data or the non-text information is related data. If it is related data, the data is directly saved. If not, the data is obtained by connecting to the parsed link address.

Step 7: After obtaining each element, use the timer to play automatically or manually page through the contents of each frame.

In this way, the user can realize the transmission of large-capacity MMS through a single MMS, and can realize continuous playback of large-capacity content and reduce the tariff.

Example 1: MMS transmission on the terminal PC suite or data card PC suite (collectively referred to as the PC suite), where the terminal PC suite refers to the software running on the PC that is compatible with the terminal, and can synchronously manage the data in the terminal, the data card PC suite , refers to the PC side software running on the PC, which is matched with the data card (user identification card such as SIM card), and can synchronously manage the data in the data card. The steps are as follows: 101. Connect the terminal to the PC via data cable or wireless (Bluetooth, WIFI, etc.) and run the PC Suite.

102. In the New MMS interface of the PC Suite, add a menu to the option to insert each element, such as Insert Picture Menu, which is displayed as: Insert local picture, insert picture in link. If you are not inserting a text and are a local element, upload it to the server or network and record its link address. If it is an element inserted in the network, the user can first browse the videos, pictures, etc. that he likes on the Internet. If selected, copy the link address directly.

If you need to upload to the server, the PC will automatically establish a Socket connection with the server and upload the required files. This server is used by users to store and share large amounts of data. The terminal and the PC side can connect to the server through the socket at any time to obtain the latest data or upload their own local data. As a request for the server to listen to the client (PC or terminal), the server can use the multi-thread mechanism to simultaneously connect to multiple clients for socket transmission and data transmission.

103. On the PC side coding module, each frame and each element are combined according to the Smil format, and the data content of each element is packaged as a link address, and then packaged into a PDU string to generate a multimedia message data packet.

104. The PC transmits the MMS data packet to the terminal through AT, Diag command or Bluetooth. 105. After receiving the MMS data packet, the terminal repackages the header information, and sends the message to the recipient through the MMS server by using the existing MMS interface.

106. When the recipient clicks to download the MMS message, the MMS packet is downloaded from the MMS server. If the recipient's terminal is connected to the PC side software, the MMS data packet is directly transmitted to the PC through the data line or Bluetooth, and the PC package on the PC side analyzes the MMS data packet according to the MMS protocol and the encoding specification. If parsing into non-text information, such as picture or audio data, the header data is parsed first. If it is not the relevant data of the non-text information, the data is obtained by connecting to the parsed link address through the socket. After obtaining the data, according to the structure of the MMS, the MMS headers and the MMS Body are decoded, and then the MMS header is in accordance with the smil format. The elements are combined and the playback preview is performed according to the time of each frame.

If the PC side software is not connected, operate directly in the terminal.

See Figure 1 for the flow chart.

Since the amount of transmitted data between the PC side and the terminal is greatly reduced, the example of the present invention makes the transmission time of the large-capacity MMS on the PC side also significantly shortened, making it easier and more convenient for the user to directly edit and send the multimedia message on the PC.

Example 2:

Send the MMS on the terminal, the steps are as follows:

201. In the terminal interface, a new menu is added to the option to insert each element, such as the Insert Picture menu, which is displayed as: Insert a local picture, insert a picture in the link. If you are inserting an element stored in the terminal, upload it to the server and record its link address. If you are inserting an element in the network, simply copy its link address. If you need to upload to the server, the terminal will automatically establish a Socket connection with the server and upload the required files. The uploading process is the same as in Embodiment 1.

202. In the encoding module on the terminal side, each frame and each element are combined according to the Smil format, and the data content of each element is packaged as a link address, and then packed into a PDU string. Use the existing MMS interface to send to the recipient via the MMS server.

203. When the recipient clicks to download the MMS message, the MMS data packet is downloaded from the MMS server. The recipient's terminal parses the data according to the MMS protocol and the encoding specification. If parsing into non-text information, such as picture or audio data, first parse the header data to determine whether it is related data of non-text information, such as determining whether it is a picture or audio format, and if not, connecting to the parsed link address through a socket. retrieve data.

After obtaining the data, according to the structure of the MMS, the MMS headers and the MMS Body are decoded, and then the elements in the MMS body are combined according to the smil format, and the playback preview is performed according to the time of each frame.

See Figure 2 for the flow chart.

Since the data packet is greatly reduced during the transmission of the MMS, a large-capacity MMS can be transmitted through a single bar, and the transmission time can be shortened. Embodiments of the present invention can be used in multimedia messaging services in terminals, terminal PC suites, and data card PC suites.
