Abstract

PURPOSE:To easily communicate messages between terminals by using different media by discriminating the kind of media used by a transmitting and receiving terminals based on received messages and transmitting a message to the receiving terminal after converting the medium of the transmitting terminal to that of the receiving terminal. CONSTITUTION:The terminal number of a transmitting source is read out from terminal information in received communication data. A medium discriminating section 6 discriminates the kind of the medium used by the transmitting terminal based on the terminal number information of the transmitting source. The discriminated results of the section 6 are sent to a medium converting section 7 as the kind of the medium before conversion. Then the terminal number of a receiving side 2 is read out from the terminal information and the section 6 discriminates the kind of the medium used by the receiving terminal 2. The section 7 successively converts the data before medium conversion into data after medium conversion and sends the data to a transmitting section 8 after inputting the data before medium conversion from a receiving section 5.

Next, the contents of communication data used in this embodiment will be explained.

FIG. 3 is a diagram showing communication data that the communication processing device 1 of this embodiment receives from a destination and communication data that is transmitted to the destination.

First, the terminal information includes the terminal number of the destination, the relay or terminal number sent from the relay destination (receiving destination), and the terminal number sent from the relay destination (
Recipient 2). As for the overall structure of the communication data, data to be transmitted before or after media conversion is added to the terminal information. Reference numeral 300 indicates communication data that is relayed through the receiving destination 1 when the communication data is transmitted from the sending destination to the receiving destination 2. Reference numeral 301 indicates communication data in a format obtained by converting the communication data 300 received by the receiving destination 1 into the media of the receiving destination 2.

Here, the media conversion method of the message communication system of this embodiment will be explained.

FIG. 4 is a flowchart explaining the operation of the CPU 2 of this embodiment.

First, when communication data is received from the network 20,
The received communication data is temporarily stored in the receiving section 5 (step SL, step S2), and the destination terminal number is read from the terminal information in the received communication data (step S3). The following will explain based on the communication data shown in FIG. In this case, the received communication data becomes communication data 300. The destination terminal number read in step S3 is r21aJ, and information on this destination terminal number is sent to the media identification section 6. The media identification unit 6 identifies media A, that is, text media, as the corresponding media type from the table 100 based on the information on the terminal number of the destination (step S4). This identification result is sent to the media conversion unit 7 as the type of media before conversion (step S
5). Next, the terminal number of receiving destination 2 is read from the terminal information (step S6). In this case, the terminal number of receiving destination 2 is r21 bJ. Information on the terminal number of the receiving destination 2 is sent to the media identifying unit 6, and the media identifying unit 6 identifies media B, that is, audio media, as the type of media that corresponds to the receiving destination 2 (step S7). . This identification result is sent to the media conversion unit 7 as the type of media after conversion (step SS).

Next, the media conversion unit 7 receives data from the reception unit 5, sequentially converts data from text media to audio data, and sends the media-converted data to the transmission unit 8.

The transmitting unit 8 sequentially stores the data input from the media converting unit (step S9). When the media conversion is completed in this way, the amount of data stored in the receiving unit 5 and transmitting unit 8 before and after media conversion is reduced. are compared in the data capacity comparison unit 9 (step 5IO). If the result of this comparison is that the data capacity after conversion is large, the communication data 300 before media conversion is stored in the data storage unit 10 (
Step 512). If the amount of data before conversion is large, the communication data 301 after media conversion is stored in the data storage unit 10 (step 513). In this way, data can be retrieved from the data storage unit 1o at any time. .

Then, when the storage of the communication data with the smaller capacity is completed in step S12 or step S13, the terminal number r21 bJ stored as the receiving destination 2 in the terminal information of the media-converted communication data 301 is
is stored as the terminal number of destination 1 (step 514). In this case, the terminal corresponding to receiving destination 2 will disappear.

Next, communication data 3 after media conversion is sent to receiving destination l.
01 is transmitted from the transmitter 8 (step 515).

In this way, when the communication data is sent to the terminal 21b for media B (audio), the terminal 21b processes the received communication data as media B (audio) data.

As described above, according to this embodiment, in a message communication system, mutual communication of messages between terminals using different media is facilitated, message storage efficiency during communication is increased, and the entire system is simplified. It is possible to provide a communication processing device using multimedia that achieves miniaturization and cost reduction.

Here, in this embodiment, the information stored in the table 100 and the terminal information is the terminal number, but the present invention is not limited to this, and the name of the terminal (including relaying equipment) may also be used. .

[Effects of the Invention] As described above, according to the present invention, in a message communication system, mutual communication of messages between terminals using different media can be facilitated, and the entire system can be simplified and miniaturized. , can be used with multimedia to realize cost reduction. Furthermore, it is possible to improve the efficiency of storing messages during communication.
