The following describes the media message transmission method of the present invention in detail. In the following description, a video message is taken as an example. It can be understood that other media messages are processed in a similar manner.

Please refer to Fig. 3, the flow of the embodiment of the media message transmission method of the present invention includes:

301. The calling user calls the access code;

Wherein, the calling user calls the service access code to initiate a media message transmission request, the number may be a local special number, and the calling user calls this number only for local calls.

302. Provide the called user number;

Wherein, after the service control point establishes the call connection between the calling user and the service server, the service server prompts the calling user to input the number of the called user, and after receiving the called user number provided by the calling user, the service server responds to the called user Verify the number to determine whether it conforms to the standard number specification. If it does, execute the follow-up process. If it does not, it prompts the calling number "The number of the called party is incorrect. Please re-enter it" and asks the calling user to re-enter it. Called user number.

Described in this embodiment is the situation that the user makes a call through a local PSTN phone or a mobile terminal, which can also be accessed through a web page. If the calling user uses a web page to transmit media messages, it is necessary to establish the For the network connection between the servers, after the call connection is established with the service server, the user name and password need to be input to verify the user identity. If the user identity authentication is passed, step 302 is executed, and if the verification is not passed, the operation is ended.

303. Collect video messages;

Wherein, after the service server receives the valid called user number, it stores the number.

The calling media device in the service server prompts the calling user to start recording a video message.

It can be understood that if the calling user has recorded the video message in advance, the calling user can directly upload the video message file to the calling media device.

In actual applications, the length of the recorded video message or the size of the uploaded video message file can be specified according to network conditions.

After the calling media device finishes collecting the calling user's video message, it stores it locally.

304. Disconnect the call connection;

Wherein, the service server releases the call connection with the calling user, and charges the calling user.

305. Forward video messages;

Wherein, the calling media device sends the video message to the called media device.

In order to reduce the cost of network transmission, the video message can be encoded first, for example: the calling media device compresses the stored voice message, for example, the video message file in AVI format is compressed into the video message in RM format.

It can be understood that, if the sent media message is a voice message, it can also be encoded in the following manner: the calling media device uses Automatic Speech Recognition (ASR, Automatic SpeechRecognition) to convert the voice message into a text file.

After encoding the video message, the calling media device queries the address of the called media device according to its destination address, and then sends the video message to the called media device through the Internet. If the transmission is unsuccessful, it will be processed according to the preset retry rules, wherein the retry rules can be formulated according to the actual situation, which can be the number of retries or the total time spent on retries. Wherein, the video message can be transmitted to the called media device through the high-speed packet switching network.

Correspondingly, if the media message is a voice message and is converted into text by using the ASR technology, the data in the text can be sent in the form of a signaling message.

In addition, the service server can also send an FTP_REQ message to the calling media device, requesting the calling media device to forward the video message to The called media device; when the calling media device forwards the video message successfully, it feeds back an FTP_ACK message to the service server, and the message includes a successful forwarding confirmation message and an identification code of the stored video message. For security reasons, configure IP firewalls on all voice station interfaces facing the IP network.

After receiving the voice message, the called media device decodes the video message, for example, decodes the video message in RM format and restores it to a video message in a format (AVI, etc.) supported by the voice network.

Similarly, if the sent media message is a voice message, and the ASR technology is used for encoding, then the called media device converts the received text file into an original voice message by means of text-to-speech (TTS, Text To Speech) mode.

The video message after decoding is stored in the called media device, and the encoded file received from the calling media device can be deleted at the same time. The called media device feeds back a decoding confirmation message to the calling media device.

306. Initiate a call connection to the called user;

After receiving the media message, the called media device initiates a call connection to the called user.

307. Play a voice message;

Wherein, if the called user answers the call, the called service control point establishes a call connection between the service server and the called user, and the called media device plays the stored video message to the called user. After starting to play the video message, provide options to the called user, including "delete message", "keep message", etc., the called user can select as required, and save the update result into the service server database log according to the user's selection.

308. Release the call.

Wherein, after the called media device successfully plays the stored video message to the called user, the service server releases the call connection with the called user.

In this embodiment, the called media device adopts the method of directly initiating a call to the called user to play a video message. It can be understood that the called media device can store the media message and send a short message to the called user or In other forms, the called user is notified of new news, and the called user actively connects to the called media device to query new news when appropriate.

The above embodiments take video messages as an example. In addition, there are some special cases. For example, when sending a video message, if the called terminal does not have the video capability, the called terminal only receives the audio content in the video message. At the same time, You can also log in to the business service website, or receive video messages through other terminals (such as PCs, PDAs, etc.).
