The present invention relates to mail transmission in a wired / wireless integrated internet network. More particularly, the present invention relates to a multilingual system and method for mail transmission that can reduce the load and memory usage of a terminal by implementing a charset decoding process in a client. It is about.

The Internet is a global computer network system. It is an open network that can be connected and used freely by applying a common protocol called TCP / IP to other computers that want to connect anywhere in the world. In addition to delivering basic text information, data compression technology has made it possible to use a variety of services such as large-capacity multimedia file transmission, e-mail, and the World Wide Web.

On the other hand, with the development of wireless communication technology, services provided by mobile communication systems are developing into multicasting multimedia communication that simultaneously transmits large amounts of data such as packet data and circuit data as well as voice services.

In addition, from the CDMA-2000 1x network, mobile communication can operate as an Internet Protocol (IP) terminal, and high-speed bidirectional data service is enabled.

Unlike wired Internet systems, wireless Internet systems have several limitations. In the case of wireless Internet systems, there are network problems such as low data communication bandwidth, data transmission time delay, instability of data communication line connection, central processing unit with low processing speed, low memory capacity, limit of battery life, small display device. However, there is a problem of a device such as an input device having only a few function buttons and numeric buttons.

Therefore, there are many problems in applying the protocol used in the wired Internet to the mobile communication terminal as it is. In order to overcome the limitations of the wireless environment, new technologies for the wireless Internet have been developed. Currently, the technology for wireless Internet access is based on the newly developed WAP (Wireless Application Protocol), which is not based on HTTP (Hypertext Transfer Protocol), which is a protocol on the wired Internet, in the WAP forum, which is mainly led by Phone.com, Ericsson, and Motorola. For example, Microsoft's Microsoft Mobile Explorer (ME) and NTT-Docomo's i-mode, which provide wireless data services based on HTTP, are typical. As a wireless Internet access technology in Korea, KTF is serving ME and SK Telecom and LG Telecom adopt WAP.

1 is a block diagram of a mail transmission system in a wired / wireless integrated internet network according to the prior art.

An example of a mail transmission system in a wired / wireless integrated internet network according to the prior art will be described with reference to FIG. 1.

The mail transmission system according to the related art includes a mobile communication terminal 100, a mobile communication network 110, a WAP gateway 120, an internet network 130, a personal computer 140 and a mail server 150.

The WAP gateway 120 performs a process such as communication code conversion or protocol conversion between the mobile communication network 110 and the internet network 130 so as to quickly search and display information on a wired Internet. It performs the function of interconnecting the 110 and the Internet network 130.

It is assumed that the mobile communication terminal 100 creates a mail including a text and transmits the mail to the personal computer 140. The mail created by the mobile communication terminal 100 is stored in the mail server 150 through the mobile communication network 110, the WAP gateway 120, and the Internet network 130. The personal computer 140 may access the internet network 130 and view the mail stored in the mail server 150. In addition, there will be a case where the mail is transmitted from the mobile communication terminal, the computer, or the computer to the mobile communication terminal. However, detailed description thereof will be omitted here.

Here, the computer or mobile communication terminal receiving the mail is provided with a language package for decoding and displaying on the screen by coding methods of each language so that mail in various languages can be viewed. For example, if you want to see the mail in English and Korean, you must install the English package and Korean package on your computer or mobile terminal to see the mail in that language.

As described above, according to the related art, when a character set used in each country is different, when a download is received from an email client receiving a mail, a decoding process to Unicode must be performed. By the way, when the code value of Unicode and the character set of the received mail coincide in the decoding process to Unicode, a separate conversion table is not required. However, if there is a mismatch, a conversion process using the Unicode conversion table is required.

As described above, the mail transmission method according to the related art has a problem that it is not suitable for a mobile communication terminal having limitations on a communication network and a terminal device. In other words, there is a problem that the central processing unit having a low processing speed and the mail transmission method that is not suitable in terms of low memory capacity.

The present invention is to solve the above problems, the present invention implements the process of decoding the character set in the client, the server, the terminal does not need to store the character set conversion table and does not need to perform the Unicode conversion operation It is an object of the present invention to provide a multilingual support system and method for mail transmission that can reduce the load and memory usage of a terminal.

As an aspect of the present invention for achieving the above object, a multilingual support system for mail transmission according to the present invention,

A transmitting terminal capable of accessing wired or wireless Internet; A receiving terminal capable of accessing wired or wireless Internet; And a mail server converting the character set of the mail received from the sending terminal into a Unicode format and transmitting the same to the receiving terminal.

In another aspect of the present invention, a multilingual support method for mail transmission according to the present invention includes: a first process of receiving a mail from a sending terminal by a mail server in a wired / wireless integrated Internet network; A second step of the mail server analyzing the received mail and converting the mail character set into a Unicode format; A third step of storing the converted mail in the mail server; And a fourth process of transmitting the converted mail to a receiving terminal.

The terms used in the present invention are described as follows.

(1) Unicode refers to the Universal Code System (UCS), which is a universal 2-character system established by international standards. Unicode unified 16-bit values for one character to facilitate data exchange. Each character of the code has a value of 7 bits in English, 8 bits in non-English, and 16 bits in Korean or Japanese, all of which are unified to 16 bits. The dials of ISO / IEC 10646-1 provide code values for characters and special symbols in 26 languages used around the world.

(2) MIME (Multipurpose Internet Mail Extension) is an Internet standard that sends multimedia data, such as text and images, audio, and video, other than ASCII format, to Internet format without the need to convert to ASCII format. An extension of the Simple Email Transfer Protocol (SMTP). Early Internet e-mails could only handle text files recorded with 7-bit ASCII code representing alphanumeric characters. However, due to the global spread of the Internet, it is necessary to exchange text and multimedia data of non-ASCII characters, including double-byte characters such as Korean, Chinese, and Japanese. That's why MIME was defined by the Internet Engineering Task Force (IETF), the Internet's standardization organization. MIME allows the transmission of non-ASCII text or multimedia data by using a MIME type that describes the content of the document being sent. When a mail program that can use MIME sends a file specifying a MIME type, the receiving application consults a list of standard documents organized by MIME type and subtype to interpret the contents of the file. For example, one of the MIME types, text, has several subtypes, plain and html. A MIME type called text / html means a file that contains text written in Hypertext Generation Language (HTML). MIME types include text, multipart, message, application, image, audio, and video.

The above objects, features and advantages of the present invention will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Like numbers refer to like elements throughout. In addition, when it is determined that the detailed description of the known function or configuration related to the present invention may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

3 is a block diagram illustrating an example of a mail server according to the present invention.

Referring to Figures 2 and 3, it will be described a preferred embodiment of a multi-language support system for sending mail according to the present invention.

Multilingual support system for mail transmission according to a preferred embodiment of the present invention, the transmitting mobile terminal 200, wired and wireless integrated Internet network 210, the receiving mobile terminal 220, the mail server 230 and personal Computer 240. In addition, the mail server 230 includes a mail receiver 300, a charset converter 310, a storage 320, a database 330, and a mail transmitter 340. The character set converter 310 includes a MIME decoder 311, a Unicode converter 313, and a MIME encoder 315. Here, the transmitting side mobile communication terminal 200 and the receiving side mobile communication terminal 220 are mobile communication terminals capable of a wired Internet or a wireless Internet connection. In addition, the mail server 230 performs a function of converting the character set of the mail received from the sender terminal 200 into a Unicode format and transmitting it to the receiver terminal 220. The database 330 stores a Unicode conversion table.

The mail receiving unit 300 receives a mail from the transmitting terminal 200 through the Internet network 210.

The charset converting unit 310 analyzes the mail received through the receiving unit 300 and converts the charset of the mail into a Unicode format. Here, when the received mail is encoded in the MIME format, the MIME decoding unit 311 MIME decodes the received mail. The Unicode conversion unit 313 converts the character set into the Unicode format when the character set of the MIME decoded mail is not in the Unicode format. UTF-8 is a widely used Unicode format. Here, the Unicode converter 313 may convert the charset of the MIME decoded mail into a Unicode format by referring to the Unicode conversion table stored in the database 330. The MIME encoding unit 315 MIME encodes the mail in which the character set is converted into a Unicode format. If the character set of the MIME decoded mail is in Unicode format, MIME encoding is performed without converting the character set. For example, if the character set of the MIME decoded mail is a Unicode format such as UTF-8, the Unicode format conversion is not necessary, and when the character set of the MIME decoded mail is not Unicode format, it is converted to a Unicode format such as UTF-8. .

The storage unit 320 stores the MIME encoded mail. The mail transmitter 340 transmits the MIME-encoded mail to the receiving terminal 220. When the receiving terminal 220 performs only MIME decoding on the received MIME-encoded mail, the receiving terminal 220 can view contents without a charset conversion table for each country. However, the receiving terminal 220 must have a Unicode decoding means.

On the other hand, the charset converting unit 310 may be activated only when the request to translate the mail received by the mail server 230 to the Unicode from the receiving terminal 220. Here, the mail server 230 and the receiving terminal 220 may communicate by using a post office protocol (POP).

In the above-described embodiment, only the case of a mobile communication terminal as a transmission / reception terminal has been described, but is not limited thereto. That is, the terminal for transmitting and receiving may include all terminals capable of transmitting and receiving mail by accessing the Internet. 2 illustrates a personal computer 240 connected to the wired / wireless integrated internet network 210. That is, the mail transmission between the personal computer 240 and the terminal 200 or 220 may also be formed in a similar form to the above-described embodiment. In addition, it is possible to send mail between personal computers in a form similar to the above-described embodiment.

4 and 5, a preferred embodiment of the multilingual support method for mail transmission according to the present invention will be described.

First, the mail server receives the mail from the sending terminal (S400).

Thereafter, the mail server analyzes the received mail, converts the character set of the mail into Unicode (S410), stores the converted mail (S420), and transmits it to the receiving terminal (S430). Here, the Unicode conversion process (S410) may be activated only when there is a Unicode translation request from the receiving terminal.

Referring to Figure 5, the Unicode conversion process (S410) will be described in more detail as follows.

First, when the received mail is encoded in the MIME format, the received mail is MIME decoded (S500). Thereafter, it is determined whether the character set of the MIME decoded mail is in Unicode format (S510). As a result of the determination, if the Unicode format, the MIME decoded mail is MIME encoded (S530). If not, the character set is converted to the Unicode format (S520), and then MIME encoded (S530). For example, if the character set of the MIME decoded mail is a Unicode format such as UTF-8, the Unicode format conversion process (S520) is not necessary, and if it is not the Unicode format, the Unicode format such as UTF-8 Convert to In operation S520 of converting the character set into the Unicode format, the character set of the decoded mail may be converted into the Unicode format by a Unicode conversion table stored in a database provided separately by the mail server.

Here, other detailed features in each process are as described in the preferred embodiment of the multilingual support system for mail transmission according to the present invention.
